Description

technical field

The invention generally relates to a mattress, in particular a combi or reversible mattress with a plurality of mattress elements stacked on top of one another, the mattress having two outer surfaces designed as lying surfaces. In particular, the mattress according to the invention can advantageously be used with box spring beds or low beds, but is not limited to these.

Background of the Invention

Mattresses have been used for a long time as a base and/or lying surface for a user and are constantly being further developed, in particular with regard to lying comfort for the user and ergonomic lying for the user. As a rule, mattresses have a maximum thickness of around 18 cm.

To improve lying comfort, mattresses can also be designed, for example, with zones, areas, support areas and/or regions of different hardness, compressibility, compression hardness and/or elasticity adjoining one another in the longitudinal direction of the mattress. In this way, a penetration depth of the user lying on the mattress can be adapted to the body shape of the user. It can also be achieved, for example, that the user lies on the mattress in the lateral position with a spine that is as straight as possible. The same applies in the supine position, in which the spine can be supported in such a way that it has the natural S-shape. By providing several support areas or areas of different compression hardness, also referred to below as ergonomic zones, a weight distribution of the user on one of the lying surfaces of the mattress can be taken into account in an advantageous manner and thus an ergonomic posture of the user, for example in several sleeping positions and/or sleeping positions of the user, be assured.

Such an ergonomic adjustment of mattresses currently only exists for mattresses with a maximum thickness of 18 cm - 20 cm, e.g. mattresses for a box spring bed or very low beds or bed frames, as are often used in southern European regions such as Spain. This can be due, among other things, to the fact that the ergonomic zones cannot be formed sufficiently well in the case of greater thicknesses, which can lead to a deterioration in the feeling of lying and ergonomics.

Summary of the Invention

Embodiments of the invention advantageously make it possible to provide a user with an improved mattress, in particular a reversible mattress, which is characterized in particular by increased lying comfort. In particular, the mattress according to the invention can also be used on low beds or bedsteads and on box spring beds with improved lying comfort.

This is made possible in particular by the subject matter of the independent claim for protection. Advantageous embodiments and developments are specified in the dependent claims and the following description.

One aspect of the present disclosure relates to a mattress, combination mattress and/or reversible mattress. In particular, the mattress can be used by a user on both sides and/or can provide two lying surfaces of different compressive strength. The mattress has at least one first mattress element with a first contact surface and a first outer surface arranged opposite, which is designed as a first lying surface for a user. Furthermore, the mattress has at least one second mattress element with a second contact surface and a second outer surface arranged opposite, which is designed as a second lying surface for a user. The first mattress element and the second mattress element are stacked on top of one another in such a way that the first contact surface of the first mattress element and the second contact surface of the second mattress element are at least partially in physical contact with one another. The first and second mattress elements can, for example, be positioned one on top of the other and/or one on top of the other. In particular, the first and second mattress element can be positioned on top of one another without further attachment, or the first and second mattress element can be connected to one another via the first and second contact surface, for example knitted, glued, attached by means of a zipper or otherwise attached. The mattress has at least one head support area for supporting a head, at least one neck support area for supporting a neck, at least one shoulder support area for supporting shoulders, at least one lumbar support area for supporting at least part of a spine and at least one pelvic support area for supporting a pelvis of the user. The first mattress element has a profile on the first outer surface and/or the second mattress element has a profile on at least one of the second outer surface and the second contact surface, so that the first mattress element and the second mattress element (and/or the first and second outer surfaces) have different compressive strengths and/or differ in their degree of hardness. A thickness of the mattress is at least 24 cm. A thickness of the mattress can be dimensioned transversely to a longitudinal axis of the mattress, transversely to a transverse axis of the mattress and/or parallel to a vertical axis of the mattress. Alternatively, the mattress can be at least 22 cm thick. The profile arranged on the second outer surface of the second mattress element has a plurality of, in particular three, recesses in the at least one pelvic support area, the plurality of recesses having a triangular cross-section, and the plurality of recesses differing at least partially in cross-sectional area

Here and below, the profile formed “on the” first and/or second outer surface can mean that the respective profile is formed in the area of, adjacent to and/or near the first and/or second outer surface. The first and/or the second outer surface can be designed to be essentially smooth and/or flat. For example, the profile formed on the first outer surface can have one or more recesses with any desired cross-section and/or any cross-sectional geometry, which each adjoin the first outer surface and/or are connected to the first outer surface, for example via an incision. Alternatively or additionally, the profile formed on the second outer surface can have one or more recesses with any desired cross-section and/or any cross-sectional geometry, which each adjoin the second outer surface and/or are connected to the second outer surface, for example via an incision.

For example, in the areas of the mattress, i.e. head support area, neck support area, shoulder support area, lumbar support area and pelvic support area, at least partially different profiles, for example with different recesses and/or indentations, can be introduced into the first outer surface and/or the second outer surface, so that the compression hardness and /or the support property of the respective area can be adjusted and/or changed, for example compared to mattress elements without a profile. As a result, a user can sink to different depths into the mattress and/or into the respective outer surface (or lying surface) on which the user is located in the respective area. A weight distribution of the user over at least part of the first and/or second lying surface can also be taken into account by the different areas. For example, with the different compression hardnesses of the areas, it can be taken into account that the user's head weighs less than the pelvis, so that the head support area can have a lower compression hardness than the pelvic support area. The different compressive strengths in the different areas can also ensure that the user's spine or back is straight, for example when the user is lying on his side, or has the typical S-shape, for example when the user is lying on his back. In addition, a different bearing surface of the user's body parts can advantageously be taken into account since, for example, a shoulder area of the user usually has a larger bearing surface than the user's head.

The profile on the first outer surface and/or at least one of the second outer surface and the second contact surface can have, for example, one or more grooves, beads, grooves, incisions, cutouts, transverse grooves, channels, indentations and/or recesses.

In particular, the profile of the first outer surface, the second outer surface, the first contact surface and/or the second contact surface can have a plurality of transverse grooves which can extend parallel to one another and/or parallel to a transverse axis of the mattress. The transverse grooves on one side or surface of the mattress can be spaced apart from one another in the longitudinal direction of the mattress, so that at least part of the respective surface or side of the mattress can be equipped with a profile.

The areas mentioned above, i.e. the head support area, the neck support area, the shoulder support area, the lumbar support area and the pelvic support area, can designate different lying zones, zones, support areas, regions and/or lying areas of the mattress. Degrees of hardness can, for example, have a large number of hardness classes. The hardness classes can be: very soft, soft to medium hard, medium hard to hard, hard, and very hard, but are not limited to these. Alternatively or additionally, the degree of hardness can be specified in H1 to H5.

By providing the first mattress element and the second mattress element, each with different degrees of hardness, a combination/reversible mattress can be provided. The user can thus choose the degree of hardness that is suitable for him by selecting the first or the second lying surface accordingly. To select the degree of firmness, the mattress can be rotated approximately 180 degrees about a longitudinal axis and/or a transverse axis of the mattress. Furthermore, by providing a mattress with a thickness of min at least 24 cm, a thicker mattress than the usual 18 cm mattress can be provided for a user, with this mattress also featuring increased lying comfort.

According to one embodiment, the first mattress element on the first outer surface and the second mattress element on the second outer surface have at least partially different profiles from one another.

By forming a first profile on the first outer surface of the first mattress element and a second profile on the second outer surface of the second mattress element, which at least partially deviates from the first profile, a lying surface with a different degree of hardness can be formed on each outer surface of the mattress element or mattress and/or or the degrees of hardness can be matched to each other. An improved combination/reversible mattress can thus be provided, for example with a hard and a softer side or outer surface. In this way, individual needs and different anatomies of different users can be taken into account, and each user can choose the side or outer surface of the mattress that suits him or her.

According to one embodiment, the thickness of the mattress is determined solely by the thickness of the first mattress element and the second mattress element, and/or the thickness of the mattress is determined by a sum of the thicknesses of the first mattress element and the second mattress element. The thickness of the mattress elements and/or the mattress can be dimensioned transversely to a longitudinal axis of the mattress, transversely to a transverse axis of the mattress and/or parallel to a vertical axis of the mattress. Alternatively or additionally, the mattress has exactly two mattress elements. Optionally, however, the mattress can also have more than two mattress elements.

According to one embodiment, the thicknesses of the first mattress element and the second mattress element are identical. Alternatively, the thicknesses of the two mattress elements can differ. In particular, the thickness of one mattress element can be greater than the thickness of the other mattress element. The compression hardness can also be changed and/or adjusted via the thickness of the respective mattress element.

According to one embodiment, the first and second mattress elements at least partially have different materials from one another. In particular, the material of one mattress element can be more elastic and/or more deformable than the material of the other mattress element. Alternatively, the materials of the first and second mattress element can be identical, but differ in one or more material properties, in particular in their elasticity and/or deformability. For example, both mattress elements can have a foam material, with a pore size of the first mattress element being able to differ from a pore size of the second mattress element, so that both mattress elements can be deformable to different extents. This can mean, for example, that a defined mass sinks deeper into the first outer surface than into the second outer surface if the first mattress element is more deformable and/or has a lower compressive strength than the second mattress element.

According to one embodiment, the thickness of the mattress is between 24 cm and 30 cm, in particular between 25 cm and 29 cm, for example around 27 cm. Mattress thicknesses of this type can be advantageous, in particular when used on box spring beds and/or low-height beds, can offer improved sleeping comfort and/or make it easier to get in and out of bed. A bed frame and/or a slatted frame can also be dispensed with entirely.

By providing a mattress with a thickness between 24 cm and 30 cm, in particular between 25 cm and 29 cm, for example around 27 cm, the mattress can be used, for example, for a box spring bed but also for lying freely, i. H. not to be used lying in any bed frame. As a result, such a mattress can also lie on a subsurface, such as the floor, and still offer improved sleeping comfort. The thickness of the mattress can also make it easier for a user to get up from the lying surface of the mattress.

According to one embodiment, the second contact surface of the second mattress element has a jagged and/or tooth-shaped profile at least in the at least one head support area, the at least one neck support area, the at least one shoulder support area and/or in the at least one lumbar support area. Alternatively or additionally, the second contact surface can also have a jagged and/or tooth-shaped profile, at least in a partial area.

In the context of the present disclosure, the serrated and/or tooth-shaped profile can designate a profile (and/or a profiling and/or a structure) which has one or more depressions and/or transverse grooves introduced into the second contact surface, so that the second mattress element in a longitudinal section through the Mattress parallel to a longitudinal axis of the mattress has a tooth-shaped and/or jagged geometry and/or contour, for example on the second contact surface, at least in a partial area.

By forming the profiles on the first outer surface and the second outer surface and by forming the serrated and/or tooth-shaped profile on the second contact surface of the second mattress element, the support properties and/or compressive strength of different areas of the mattress, in particular the headrest area, the neck support area , the shoulder support area and/or the lordosis support area are designed differently from one another or from the pelvic support area. In addition, such a profile can be introduced into the second contact surface in a cost-effective, reliable, fast and precise manner. In addition, with such a profile, the compressive strength and/or support properties of individual areas of the mattress can be adjusted efficiently and effectively.

Alternatively or additionally, different compressive strengths can be achieved by using different materials, such as materials of different hardness or softness, such as mattress foam and/or polyurethane foam.

According to one embodiment, the jagged and/or tooth-shaped profile has at least one indentation (and/or transverse groove) with a rectangular cross-section. Optionally, several transverse grooves with a rectangular cross section can be provided, which can extend essentially parallel to one another and parallel to a transverse axis of the mattress. In this way, the compression hardness and/or support properties can be adjusted efficiently and effectively in the areas of the mattress in which the jagged and/or tooth-shaped profile is present. Different transverse grooves can be spaced apart from one another in the longitudinal direction of the mattress.

The cross section of the indentation can be related to the at least one indentation. In other words, the cross section can denote a cross section through the depression. A cross section through an indentation can, for example, represent a longitudinal section through the mattress, in particular if the indentation runs essentially parallel to a transverse axis of the mattress or extends parallel to a transverse axis of the mattress. In other words, the cross section of the recess can run parallel to a longitudinal axis and/or be given by a longitudinal section through the mattress. The indentation with a rectangular cross-section can also be referred to below as a rectangular indentation.

According to one embodiment, the at least one indentation, in particular a rectangular indentation, of the jagged and/or tooth-shaped profile extends over an entire width of the mattress essentially parallel to a transverse axis of the mattress. In particular, several indentations can be provided, each of which can extend over an entire width parallel to the transverse axis of the mattress and/or parallel to one another. In this way, the compression hardness and/or support properties can be adjusted efficiently and effectively in the areas of the mattress in which the jagged and/or tooth-shaped profile is present.

The indentations can be introduced into the second contact surface, the first contact surface, the first outer surface and/or the second outer surface, for example using a cutting tool. The indentations can extend completely through the mattress from a first transverse side of the mattress to a second, opposite transverse side of the mattress. A depth of the depressions can be dimensioned in a vertical direction and/or parallel to a vertical axis of the mattress, starting from the respective side or surface of the mattress.

According to one embodiment, the jagged and/or tooth-shaped profile is formed exclusively on the second contact surface of the second mattress element and/or the first contact surface of the first mattress element is profile-free, smooth and/or flat. No profile means that no profile is formed on the first contact surface of the first mattress element and/or no depressions are formed on the first contact surface. In this context, smooth means that the first contact surface of the first mattress element has no structuring, elevations and/or recesses. As a result, different degrees of hardness can be provided for the first lying surface and the second lying surface in an advantageous manner. In addition, different support properties and/or compressive strengths can advantageously be provided by the formation of these areas of the jagged and/or tooth-shaped profile.

According to one embodiment, the indentations of the serrated and/or tooth-shaped profile are spaced equidistantly in the longitudinal direction of the mattress, in particular parallel to the longitudinal axis. In other words, directly adjacent indentations of the serrated and/or tooth-shaped profile are spaced an identical distance from one another. This allows the compression hair ten and/or support properties can be adjusted efficiently and effectively in the areas of the mattress where the jagged and/or toothed profile is present.

According to one embodiment, the distance in the longitudinal direction of the mattress between the indentations of the serrated and/or tooth-shaped profile is equal to a length or width or dimension of the respective indentation in the longitudinal direction of the mattress. In other words, two adjacent indentations are arranged in such a way that the adjacent indentations are spaced apart by a distance which corresponds to the respective dimension of the indentations in the longitudinal direction of the mattress.

According to one embodiment, the indentations of the jagged and/or tooth-shaped profile have identical depths. As an alternative or in addition, the indentations of the jagged and/or tooth-shaped profile are made at the same depth in the second contact surface of the second mattress element. In particular, this can simplify the manufacture of the mattress and enable the ergonomic zones to be formed in a targeted manner.

According to one embodiment, the jagged and/or tooth-shaped profile is embodied symmetrically, in particular mirror-symmetrically, relative to a central transverse axis and/or a central transverse plane of the mattress.

According to one embodiment, the first outer surface of the first mattress element and the second outer surface of the second mattress element each have a profile, and the profile formed on the first outer surface and the profile formed on the second outer surface are each embodied symmetrically, in particular mirror-symmetrically, relative to a central transverse axis of the mattress .

The symmetrical configuration of the jagged and/or tooth-shaped profile makes it easier to manufacture the mattress and reduces manufacturing costs, since the jagged and/or tooth-shaped profile of the mattress can be machined with the same tool. Handling of the mattress can also be simplified, since the user only has to choose the lying surface that suits him.

According to one embodiment, the profile formed on the first outer surface of the first mattress element and/or the profile formed on the second outer surface of the second mattress element has at least one recess with a round, rounded, triangular, rounded, circular, elliptical, oval T-shaped and/or or drop-shaped cross-section. Here and in the following, the recess can denote a cavity and/or a cavity formed at least partially in the first and/or second mattress element. The recesses of the respective profiles, in particular the profiles formed on the first and second outer surface, can in principle have any depth, arrangement, cross-sectional geometries, cross-sectional areas and/or cross-sections, such as T-shaped, triangular, quadrangular, rectangular, cuboid, polygonal, round , oval and/or elliptical cross-sections (or cross-sectional geometries).

According to one embodiment, at least one recess of the profile formed on the first outer surface of the first mattress element extends over an entire width of the mattress, for example in the transverse direction of the mattress, and is from the first outer surface of the first mattress element in a vertical direction of the mattress (and/or parallel to a vertical axis) spaced, so that the at least one recess is formed in an inner volume of the first mattress element. The at least one recess is opened in the direction of the first outer surface via an incision extending through the mattress parallel to the at least one recess in the transverse direction of the mattress. The recess can be connected, so to speak, to the first outer surface via the incision. A width of the incision measured parallel to the longitudinal axis can be smaller than a width (and/or a diameter) of the recess measured parallel to the longitudinal axis. Such a design of the profile formed on the first outer surface allows the first outer surface to be designed to be essentially planar and/or smooth, since the recess can be at least partially covered by a layer of the first outer surface. Thus, the recess cannot be felt by the user and lying comfort can be increased.

According to one embodiment, at least one recess of the profile formed on the second outer surface of the second mattress element extends over an entire width of the mattress, for example in the transverse direction of the mattress, and is from the second outer surface of the second mattress element in a vertical direction of the mattress (and/or parallel to the vertical axis) spaced, so that the at least one recess is formed in an inner volume of the second mattress element. The at least one recess is opened in the direction of the second outer surface via an incision extending through the mattress parallel to the at least one recess in the transverse direction of the mattress. The recess can be connected to the second outer surface, so to speak, via the incision. A parallel The width of the incision measured relative to the longitudinal axis can be smaller than a width (and/or a diameter) of the recess measured parallel to the longitudinal axis. Such a design of the profile formed on the second outer surface allows the second outer surface to be designed to be essentially planar and/or smooth, since the recess can be at least partially covered by a layer of the second outer surface. Thus, the recess cannot be felt by the user and lying comfort can be increased.

According to one embodiment, the profile formed on the first outer surface of the first mattress element and the profile formed on the second outer surface of the second mattress element have a plurality of recesses. Furthermore, a diameter and/or a cross-sectional area of at least some of the recesses differ from one another. This allows the support properties to be adjusted in certain areas, for example to form the ergonomic zones.

According to one embodiment, a depth and/or cross-sectional area of at least part of the recesses of the profile formed on the first outer surface of the first mattress element differs from a depth and/or cross-sectional area of at least part of the recesses of the profile formed on the second outer surface of the second mattress element. As a result, different compressive strengths of the two outer surfaces can be provided.

Alternatively or additionally, the depth of the recesses of the profile formed on the first outer surface of the first mattress element and of the recesses of the profile formed on the second outer surface of the second mattress element depends on the cross-sectional area of the recesses. The depth of a recess can designate the orthogonal distance of the recess from the associated outer or contact surface in which the recess is made. In other words, the depth of the recesses differs depending on the cross-sectional area of the recesses. For example, recesses with a larger cross-sectional area have a greater depth and/or a greater distance from the respective outer surface, measured in the vertical direction of the mattress, than recesses with a smaller cross-sectional area. Similarly, recesses with a smaller cross-sectional area have a shallower depth than recesses with a large cross-sectional area. Recesses with the same cross-sectional area can have an identical depth.

According to one embodiment, recesses (synonymously also referred to as indentation or transverse groove) of the profile formed on the first outer surface of the first mattress element and of the profile formed on the second outer surface of the second mattress element with an identical cross-sectional area have an identical depth.

According to one embodiment, a single recess of the profile formed on the first outer surface of the first mattress element and of the profile formed on the second outer surface of the second mattress element is formed in the at least one headrest area. A suitable bush hardness and preferred ergonomics of the headrest area can thereby be provided.

According to one embodiment, several, in particular five, recesses of the profile formed on the first outer surface of the first mattress element and of the profile formed on the second outer surface of the second mattress element are formed in the at least one shoulder support area. As a result, a suitable bush hardness and a preferred ergonomics of the shoulder support area can be provided.

According to one embodiment, the multiple recesses of the profile formed on the first outer surface of the first mattress element are formed identically in the at least one shoulder support area.

According to one embodiment, the diameter and/or the cross-sectional area of the respective recesses of the profile formed on the second outer surface of the second mattress element decreases, starting from an end of the at least one shoulder support area adjoining the head area to an end of the at least one lumbar support area adjoining the pelvic support area. The diameter and/or the cross-sectional area of the respective recesses can decrease step by step and/or continuously, but is not limited to this.

According to one embodiment, several, in particular three, recesses of the profile formed on the first outer surface of the first mattress element are formed in the at least one pelvic support area. A suitable bush hardness and preferred ergonomics of the pelvic support area can thereby be provided.

According to one embodiment, the plurality of recesses of the profile formed on the first outer surface of the first mattress element differ at least partially in the transverse direction in the at least one pelvic support area interface. For example, the recesses can differ in their cross-section, their depth, their cross-sectional area, shape, geometry, direction of extension and/or length

According to one embodiment, at least one of the plurality of recesses in the profile formed on the first outer surface of the first mattress element in the at least one pelvic support area is aligned with the one single recess in the profile formed on the first outer surface of the first mattress element and the profile formed on the second outer surface of the second mattress element identical in the at least one headrest area. In other words, at least one of the recesses formed in the pelvic area is identical to the single recess formed in the headrest area. A suitable bush hardness and preferred ergonomics of the pelvic support area can thereby be provided.

According to one embodiment, the mattress, the first mattress element and/or the second mattress element has a first half and a second half, which are arranged one behind the other in the longitudinal direction and/or parallel to the longitudinal axis of the mattress, with the mattress, the first mattress element and/or the second mattress element has a head support area, a neck support area, a shoulder support area, a lumbar support area and a pelvic support area in the first half and in the second half.

The support areas or areas can be formed in each of the first and second halves of the mattress, for example, as described below. A headrest region extends from each end of the mattress in the direction of the central transverse axis. A neck support area connects to each of the head support areas and extends further in the direction of the central transverse axis. A shoulder support area adjoins each of the neck support areas and extends further in the direction of the central transverse axis. A lordosis support area connects to each shoulder support area and extends in the direction of the central transverse axis. A pelvic support area connects to each lumbar support area and extends to the central transverse axis. The two pelvic support areas of the first half and the second half can, as it were, form a common pelvic support area.

According to one embodiment, the first half and the second half are formed symmetrically to one another, in particular mirror-symmetrically, relative to a central transverse axis and/or a central transverse plane of the mattress. Due to the symmetrical design of the first half and the second half of the mattress, manufacture of the mattress can be simplified and manufacturing costs can be reduced since the two halves of the mattress can be machined with the same tool.

According to one embodiment, the first mattress element and/or the second mattress element is made from a foam, in particular a viscoelastic foam, a cold foam, a point-elastic foam and/or a polyurethane foam.

However, other materials such as latex, natural latex, layered latex, gel foam and/or polystyrene are also possible. The individual mattress elements can be made from identical material or at least some of the mattress elements can be made from different materials. The mattress elements can also have different colors, at least in part, for example to show a user the respective degree of hardness of the lying surface. For example, a color of the first mattress element can differ from a color of the second mattress element. Furthermore, the first mattress element and/or the second mattress element can be formed completely or at least partially from a foam.

By using a foam, an unwanted draft or an unwanted air circulation through the mattress or the first mattress element and/or the second mattress element can be reliably prevented. A feeling of warmth, i. H. whether the mattress feels warm when used by a user can be provided and the lying comfort can be improved. In particular, insulation from the floor can be improved, for example compared to innerspring mattresses.

According to one embodiment, the mattress also has a mattress cover which at least partially, in particular completely, encloses the first mattress element and the second mattress element, with the mattress cover having a first half and a second half which are at least partially closed with a fastener, in particular a zipper, are connectable to each other along at least part of an outer circumference of the mattress.

By providing a mattress cover on the mattress, damage to and/or soiling of the mattress can be reliably prevented and the haptic properties or the feeling of lying on the mattress by the user can be improved.

The mattress cover can be opened via the fastener and completely removed, for example to wash the mattress cover. The mattress cover can be washed in particular at a washing temperature of up to around 75° Celsius, for example up to around 60° Celsius, which can advantageously simplify and/or enable comprehensive cleaning of the mattress cover.

According to one embodiment, the first half of the mattress cover differs at least partially with regard to a fabric structure and/or a fabric type of a cover material forming the mattress cover (or the first half of the mattress cover) from a cover material forming the second half of the mattress cover. Alternatively or additionally, the two halves of the mattress cover can have different colors. This can enable the user to be shown by the different structure and/or color of the respective half of the mattress cover which side and/or which of the first and second lying surface has a desired degree of hardness. In other words, the user can use the color and/or structure of the mattress cover (or the halves of the mattress cover) to determine which lying surface has the desired degree of hardness. The color and/or structure of the respective half of the mattress cover can be an indicator of the degree of hardness of the first and/or second lying surface, which is covered by the respective half of the mattress cover. This means that the user can choose the lying surface that suits him or her without having to remove the mattress cover. Overall, this can simplify handling of the mattress for the user.

The first half of the mattress cover can, in particular, at least partially enclose the first mattress element. The cover material of the first half of the mattress cover can be designed in one or more layers. For example, the cover material of the first half of the mattress cover can have an upper layer forming an outer material, which can serve as a support surface for the user. In addition, the cover material of the first half of the mattress cover can have a lower layer which can be at least partially in physical contact with the first outer surface of the first mattress element. A layer of wadding, such as a layer of polyester wadding and/or climate wadding, can optionally be arranged between the upper layer and the lower layer. As a result, the upholstery fabric can be given a pleasantly soft feel, volumization and/or a certain compressibility.

The cover material of the first half of the mattress cover can also have honeycomb-like and/or honeycomb-shaped depressions, which can be arranged in the cover material, for example in a regular pattern. The wadding layer can be fixed between the upper layer and the lower layer in an advantageous manner by means of the honeycomb-like depressions.

The cover material of the second half of the mattress cover can also be designed analogously and/or identically to the cover material of the first half of the mattress cover. Alternatively, however, the cover material of the second half of the mattress cover can differ from the cover material of the first half of the mattress cover, in particular with regard to a structure, a type of material, a material composition and/or a material structure. For example, the cover material of the second half of the mattress cover can be at least partially siliconized and/or rubberized. For example, a layer of latex may be applied to an outer surface of the cover fabric of the second half of the mattress cover. In particular, this can prevent the mattress from slipping on a support surface, such as a bed. This can be of particular advantage in the case of box spring beds, since here the mattress is regularly not held laterally by the boundary surfaces of the bed and/or bed frame.

According to one embodiment, the cover material of the first half and/or the second half of the mattress cover is made at least partially, in particular completely, from a spacer knitted fabric, for example a three-dimensional spacer knitted fabric, with the mattress cover preferably having a honeycomb structure on its outside, a honeycomb structure and/or has a honeycomb mesh structure with recesses open to the outside. In this way, a breathable surface of the mattress can advantageously be provided, which can further improve lying comfort for the user. A mattress cover made from a knitted spacer fabric can also have an advantageous haptic effect, in particular in comparison to a mattress cover made from a knitted spacer fabric, so that the mattress cover can feel soft and not scratchy. The honeycomb recesses can have any desired cross-sections, in particular round, oval, elliptical, angular and/or polygonal cross-sections. The spacer knitted fabric can be multi-layered, in particular two-layered or three-layered.

The recesses, such as the recesses open to the outside, can be variable in terms of their geometry, for example round, square, oval, polygonal, elliptical or else be designed in any other way with regard to their open cross section. The at least on the outside of the In the context of the present disclosure, recesses formed in the upper layer of the covering material are to be strictly distinguished from meshes, from which the covering material, the lower layer and/or the upper layer can be formed. The cutouts can be larger than the meshes, for example the cutouts can have a cross-sectional area that can be many times (approximately 5 to 100 times or more) larger than an average cross-sectional area of the meshes of the cover material.

The knitted spacer fabric can have, for example, a spacer structure with stitches made from knitted monofilament or multifilament spacer threads. Due to the structural composition of spacer fabrics, these can be more elastic than spacer fabrics, which can increase comfort for the user of the mattress, since the mattress cover with spacer fabric can be made soft, elastic and pleasant to the touch. In addition, air circulation and moisture removal from the mattress can be increased via the honeycomb structure on the outside of the mattress cover.

The honeycomb-like recesses open to the outside are not only advantageous in terms of air exchange and moisture transport as well as the compensation of temperature fluctuations in general, but can also enable increased elasticity, which offers the user a soft feel and also allows the Mattress cover adapts optimally to the user lying on it, without this being adversely affected by the brittle spacer threads that are often noticeable in spacer knitted fabrics.

The mattress cover can be produced, for example, on a large circular knitting machine working according to the so-called 3-way technique with a high throughput and therefore high cost-effectiveness.

The recesses of the mesh structure are preferably provided in a regular arrangement on the outside of the cover material and/or the mattress cover, although an irregular arrangement, for example an arrangement forming a pattern, is also conceivable.

The honeycomb-like recesses open to the outside can be variable in terms of their geometry, for example round, elliptical and/or oval and/or angular in terms of their open cross section.

According to one embodiment, the cover material and/or the mattress cover made of 3D spacer fabric is formed in at least two layers with an upper layer forming the outside and a fabric layer preferably made of polyester fiber fabric forming an inner layer.

The inner layer can form a smooth fabric layer, which can also be jacquard and, for example, provided with a pattern, and on which the upper layer of the 3D spacer fabric made of textured, twisted yarn, in particular multifilament yarn, can be formed on the outside.

The honeycomb-like recesses can extend at least essentially over the entire thickness of the upper layer, i.e. from the outside optionally through one or more middle layers to the inner layer or close to it, in order to achieve optimal air conditioning with regard to the air and To allow moisture exchange between the two sides of the cover fabric. In addition, the depth of the honeycomb recess increases the softness of the upper layer made of 3D spacer fabric, which means that an improved feel can be obtained.

The cover material and/or the mattress cover can also be constructed in three layers. For example, the cover fabric may have a middle layer knitted to the top layer with a monofilament yarn as a filler. As a result, with simultaneous high air and moisture permeability, stabilization and volumization of the 3D spacer fabric, which is often desired in terms of feel, can be achieved. According to a preferred embodiment, the monofilament yarn can be formed from polyester, but other synthetic fibers such as fibers formed from polyamide can also be used for this purpose.

In order to give the outward-facing surface or outside of the knitted spacer fabric, the cover fabric and/or the mattress cover a particularly smooth and pleasant feel, the surface of the cover fabric and/or the mattress cover surrounding the honeycomb-like recesses can be made of particularly fine knitted stitches.

Studies have shown that it is particularly advantageous in terms of comfort and microclimate control if the upper layer of the knitted spacer has a weight proportion of 50% to 70%, in particular 55% to 60%, of the cover fabric and/or the mattress cover.

The inner layer can have a weight proportion of 20% to 30%, in particular 25% to 30%, of the cover material and/or the mattress cover.

When using a filler, optimal results in terms of air permeability, stabilization and volumization were determined with a weight proportion of 10% to 20%, in particular 15% to 20%, of the middle layer on the cover fabric and/or the mattress cover.

The cover material and/or the mattress cover can have a weight of 200 g/m ² to 300 g/m ² , which means that it can have the required durability and at the same time is easy to handle in terms of its weight during manufacture and use.

Optionally, the mattress cover can be made at least partially from a natural fiber in the upper layer and/or the lower layer of the cover material. The use of natural fibers, which can be contained and/or knitted into the spacer fabric, for example, can increase the sustainability and/or ecology of the wet protection cover, for example since the natural fibers can be obtained from renewable raw materials. Natural fibers can also be characterized by increased resilience and/or durability. In addition, natural fibers can result in a pleasant, soft feel for the user. Natural fibers can also be characterized by increased skin compatibility, breathability and/or odor neutrality. In addition, natural fibers can enable cost-efficient production of the cover.

According to one embodiment, the natural fiber is animal hair fiber, wool fiber, cotton fiber, hemp fiber, eucalyptus fiber, bamboo fiber, linen fiber, wood fiber, viscose fiber, flax fiber, silk fiber, plant fiber, or a combination thereof. In comparison to synthetic fibers, such natural fibers can be characterized by increased sustainability, odor neutrality, skin compatibility, durability and/or robustness.

According to one embodiment, the upper layer, the lower layer and/or one or more middle layers of the upholstery fabric have a proportion by weight of natural fibers, based approximately on the respective layer or the entire upholstery fabric, of 2% to 99%, for example at least 5% 10%, at least 15%, at least 20% and/or at least 25%. At least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, or 75% of natural fibers is also conceivable.

According to one embodiment, the proportion, for example the proportion by weight and/or the proportion by volume, of natural fibers, for example in relation to the respective layer or the entire cover fabric, in the upper layer is greater than the proportion, for example the proportion by weight and/or the proportion by volume, of natural fibers in the lower and/or one or more middle layers. For example, the proportion in the upper layer can be at least twice as large as the corresponding proportion of natural fibers in the lower and/or one or more middle layers.

According to one embodiment, the upper layer consists essentially and/or almost completely, for example completely, of natural fibers and the lower layer and optionally one or more middle layers consist essentially and/or almost completely, for example completely, of synthetic fibers.

The mattress cover made of spacer fabric can be formed on all sides of the mattress, i.e. in particular on the first half and the second half of the mattress cover. Alternatively, for example, only the first half or the second half of the mattress cover can be made of spacer fabric.

Examples of possible embodiments of the mattress cover are summarized below.

The mattress cover can have a cover material and/or be made of a cover material which has a 3-D spacer fabric at least on one outside of the mattress cover and has a honeycomb mesh structure with outwardly open recesses on the outside.

The cover fabric and/or the mattress cover can have at least two layers of 3-D spacer fabric with an upper layer of textured, twisted yarn, in particular multifilament yarn, forming the outside of the mattress cover (or the cover fabric), and an inner layer of preferably smooth Polyester yarn be formed.

The cover material and/or the mattress cover can be constructed in three layers with a middle layer knitted with the upper layer with a monofilament yarn as a filler, the monofilament yarn preferably being made of polyester or polyamide.

The honeycomb recesses can extend at least essentially over the thickness of the upper layer and optionally the thickness of the middle layer.

The upper layer can have a weight proportion of 50% to 70%, in particular 55% to 60%, of the cover fabric and/or the mattress cover.

The inner layer can have a weight proportion of 20% to 30%, in particular 25% to 30%, of the cover material and/or the mattress cover.

The middle layer can have a weight proportion of 10% to 20%, in particular 15% to 20%, of the cover material and/or the mattress cover.

The cover material and/or the mattress cover can have a mass per unit area of around 250 g/m ² to 300 g/m ² .

The cover material and/or the mattress cover can be the same on all sides of the mattress.

Detailed description of exemplary embodiments

1 shows a schematic plan view of a mattress 10 according to an embodiment of the invention. 2 12 shows a perspective view of the mattress 10 of FIG 1 .

The mattress 10 has a first half 12a and a second half 12b which are arranged one behind the other along a longitudinal axis 14 of the mattress 10 . The longitudinal axis 14 can, as in 1 indicated as an example, parallel to that in the 1 x-axis shown. A longitudinal direction, ie the x-axis, of the mattress 10 can run parallel to the longitudinal axis 14 . Transversely and/or orthogonally to the longitudinal axis 14, the mattress 10 has a transverse axis 16 which is parallel to the y-axis of the 1 can run. A transverse direction, ie the y-axis, of the mattress 10 can here run parallel to the transverse axis 16 . In the 1 The transverse axis 16 shown here can denote a central transverse axis 16 which separates and/or delimits the halves 12a and 12b from one another. In 2 a central transverse plane 17 through the mattress 10 is illustrated in the area of the central transverse axis 16 . The central transverse plane 17 can lie in a plane which is spanned by the transverse axis 16 and a vertical axis (not shown) of the mattress 10 or the z-axis. A vertical direction of the mattress 10 can run parallel to the vertical axis or z-axis. The vertical axis can be parallel to the z-axis of the 2 run and run transversely and/or orthogonally to the longitudinal axis 14 and to the transverse axis 16 . A length of the mattress 10 can be dimensioned parallel to the longitudinal axis 14, a width of the mattress 10 can be dimensioned parallel to the transverse axis 16 and a thickness (or height) of the mattress 10 can be dimensioned parallel to the vertical axis (z-axis).

In 1 the individual areas and/or support areas of the mattress 10 are illustrated schematically. In the first half 12a, the mattress 10 has a first head support area 20a, a first neck support area 22a, a first shoulder support area 24a, a first lumbar support area 26a and a first pelvic support area 28a, which are arranged one behind the other starting from a first end 18a of the mattress 10 in the direction of the central transverse axis 16 and/or the central transverse plane 17 of the mattress 10 are arranged.

Analogously to the first half 12a, the mattress 10 has in the second half 12b a second head support area 20b, a second neck support area 22b, a second shoulder support area 24b, a second lumbar support area 26b and a second pelvic support area 28b, which are connected one behind the other from a second, first end 18a in the longitudinal direction of the mattress 10 opposite end 18b of the mattress 10 in the direction of the central transverse axis 16 and/or the central transverse plane 17 of the mattress 10 . The first half 12a and the second half 12b of the mattress 10 are therefore symmetrical, in particular mirror-symmetrical, with respect to the areas 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b, 28a, 28b relative to the central transverse axis 16 and/or to the central transverse plane 17 , educated.

2 FIG. 12 shows a perspective sectional view along the longitudinal axis 14 of the mattress 10. FIG 1 , ie a longitudinal section through the mattress. The mattress 10 includes a first mattress member 30 having a first outer surface 32 and an opposite first outer surface 32 ordered first contact surface 34 on. The first outer surface 32 forms a first lying surface 32 for a user. Furthermore, the mattress 10 has a second mattress element 40 with a second outer surface 42, which serves as a second lying surface 42 for the user, and a second contact surface 44 arranged opposite thereto. As described above and below, the first lying surface/outer surface 32 can differ in terms of a degree of firmness from the second lying surface/outer surface 42 so that the user can choose the degree of firmness that is suitable or suitable for him or her by turning the mattress 10 over.

The first mattress element 30 and the second mattress element 40 are arranged and/or stacked on top of one another in such a way that the first contact surface 34 of the first mattress element 30 is at least partially in physical contact with the second contact surface 44 of the second mattress element 40. The first contact surface 34 can thus be at least partially placed and/or rest on the second contact surface 44 (and/or vice versa).

The mattress elements 30, 40 can have essentially identical lengths, widths and/or thicknesses. Alternatively, a thickness of the first mattress element 30 can differ from a thickness of the second mattress element 40 . A thickness of the first mattress element 30 and/or the second mattress element 40 can be influenced by the degree of hardness of the material used for the respective mattress elements 30 and 40 . Different degrees of hardness of the mattress elements 30 and 40 are shown or indicated with different colors of the foams/the material.

Like in the 2 is clearly recognizable, the first contact surface 34 of the first mattress element 30 is planar, smooth and/or flat, in particular completely planar, smooth and/or flat. In other words, the first mattress element 30 has no structure, no profile and/or no indentations on the first contact surface 34 (apart from unevenness in the material of the first mattress element 30). Alternatively, however, a profile can also be provided on the first contact surface 34 .

At least in a partial area, the second contact surface 34 of the second mattress element 40 has a profile 36 with a plurality of depressions 38 . The depressions 38 of the second contact surface 44 are designed as transverse grooves 38, which extend across the entire width of the mattress 10 and/or the second mattress element 40, each parallel to the transverse axis 16 and parallel to the vertical axis into the second mattress element 40, i.e. into the interior volume of the second mattress element 40, protrude. Depressions 38 may also be referred to as recesses 38 and/or transverse grooves 38 in the present disclosure.

Like in the 2 recognizable, the depressions 38 of the profile 36 of the second contact surface 44 have a substantially rectangular cross section and/or a substantially rectangular cross-sectional geometry. The individual rectangular depressions 38 are open to the outside and/or in a direction parallel to a surface normal vector of the second contact surface 44 . In the cross section of 2 the profile is therefore to be seen as a tooth-shaped profile with several teeth. The depressions 38 are delimited by the first contact surface 34 of the first mattress element 30 .

Corners of the cross section of the rectangular depressions 38 are essentially pointed, i.e. with a 90° angle, but can alternatively also be rounded. In principle, the depressions 38 can have any other cross-sectional geometry. For example, a cross section and/or a cross sectional geometry of the depressions 38 can also be triangular, oval, round, elliptical, T-shaped, square, trapezoidal and/or polygonal.

The depressions 38 are formed in particular in the two head support areas 20a, 20b, the two neck support areas 22a, 22b, the two shoulder support areas 24a, 24b and/or in the two lumbar support areas 26a, 26b. Any number of rectangular depressions 38 per area 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b of the second contact surface 44 is fundamentally arbitrary. For example, 22, i.e. 11 per half of mattress 10, wells are provided in areas 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b.

A dimension and/or width of the depressions 38 measured parallel to the longitudinal axis 14 of the mattress 10 can be between around 0.5 cm and 5 cm, in particular between 1 cm and 3 cm, for example. A depth of the depressions 38 measured parallel to the vertical axis can be between 0.5 cm and 5 cm, for example between 1 cm and 3 cm.

Directly adjacent indentations 38 of the rectangular indentations 38 can be essentially the same distance apart, it being possible for a distance between adjacent indentations 38 to be dimensioned parallel to the longitudinal axis 14 of the mattress 10 . Also directly adjacent wells 38 may be at different distances from each other in comparison to further directly adjacent depressions 38 . The spacing of directly adjacent indentations 38 of the rectangular indentations 38 may be substantially equal to the width of the indentations 38 . The depth of the depressions 38 can be dimensioned parallel to the vertical axis (or z-axis) of the mattress 10 starting from the second contact surface 44 . The width here can be dimensioned parallel to the longitudinal axis 14 of the mattress 10 .

The profile 36 can optionally be embodied symmetrically, approximately mirror-symmetrically, relative to the central transverse axis 16 . in the in 2 shown embodiment, the profile 36 is shown mirror-symmetrical to the center plane of the mattress.

On the first outer surface 32, the first mattress element 30 also has a profile 46 with a plurality of recesses 48, depressions 48 and/or transverse grooves 48. The recesses 48 extend completely through the first mattress element 30, starting from a first transverse side of the first mattress element 30 to an opposite, second transverse side of the first mattress element 30. The recesses 48 have, for example, a round, T-shaped, semicircular and/or circular cross section . Alternatively, however, the recesses 48 can also have any other desired cross section, for example an angular, elliptical, polygonal and/or drop-shaped. Each of the recesses 48 is spaced apart from the first outer surface 32 in a direction parallel to the vertical axis of the mattress 10, so that each of the recesses 48 extends through or into the first mattress element 30 in an inner volume of the first mattress element parallel to the transverse axis 16.

A vertical distance, measured parallel to the vertical axis, between the first outer surface 32 and each of the recesses 48 , in particular the deepest point of the recesses 48 , depends on the corresponding shape or cross-sectional area of the recesses 48 . For example, recesses 48 having a circular cross-sectional area are spaced farther apart than recesses 48 having a T-shaped cross-sectional area or recesses 48 having a semi-circular cross-sectional area. In other words, the corresponding depth of the recesses 48 depends on their cross-sectional area.

Each of the recesses 48 is open via an incision 47 in the direction of the first outer surface 32 , the incisions 47 extending parallel to the recesses 48 over the entire width of the mattress 10 . The recesses 48 are, as it were, connected to the first outer surface 32 via the incisions 47 . Between each of the recesses 48 and the first outer surface 32, apart from the incisions 47, there is a (thin) material layer of material of the first mattress element 30. The recesses 48 are therefore each of a material layer of the first mattress element 30, apart from the incisions 47 covered, so that the recesses 48 are not or hardly noticeable for a user located on the first outer surface 32 .

In the example of 2 the recesses 48 are formed at least partially in the head support areas 20a, 20b, the neck support areas 22a, 22b, the shoulder support areas 24a, 24b, the lumbar support areas 26a, 26b, and the pelvic support areas 28a, 28b of the first mattress element 30. In detail, a recess 48 with a T-shaped cross-sectional area is provided in each of the headrest areas 20a, 20b. Five recesses 48 with a circular cross-sectional area are provided in each of the shoulder support areas 24a, 24b. A recess 48 with a semicircular cross-sectional area is provided in each of the lumbar support areas 26a and 26b. In the pelvic support portions 28a and 28b, three recesses having a T-shaped cross-sectional area are provided together. No recesses 48 may be provided in the neck support areas 22a, 22b. However, there may be more or fewer recesses 48 in each of the portions or halves 12a, 12b. The recesses 48 with a circular cross-sectional area have an identical depth. The recesses 48 with a T-shaped cross-sectional area have an identical depth. The recesses 48 with a semi-circular cross-sectional area have an identical depth.

On the second outer surface 42, the second mattress element 40 also has a further profile 50 with a plurality of recesses 52, depressions 52 and/or transverse grooves 52. The recesses 52 extend completely through the second mattress element 40, starting from a first transverse side of the second mattress element 40 to an opposite second transverse side of the second mattress element 40. The recesses 52 have, for example, a round, triangular, T-shaped, semicircular and/or circular shape cross section. Alternatively, however, the recesses 52 can also have any other desired cross section, for example an angular, elliptical, polygonal and/or drop-shaped. Each of the recesses 52 is spaced apart from the second outer surface 42 in a direction parallel to the vertical axis of the mattress 10, so that each of the recesses 52 is in an inner volume of the second mattress element 40 extends parallel to the transverse axis 16 through or into the second mattress element 40 . A vertical distance, measured parallel to the vertical axis, between the second outer surface 42 and each of the recesses 52 is smaller than a distance between the second contact surface 44 and each of the recesses 52.

A vertical distance, measured parallel to the vertical axis, between the second outer surface 42 and each of the recesses 52 , in particular the deepest point of the recesses 52 , depends on the corresponding shape or cross-sectional area of the recesses 52 . The recesses 52 formed on the second outer surface 42 have a larger diameter, at least partially a larger cross-sectional area and/or larger dimensions than the recesses 48 . Starting from each end of the shoulder support areas 24a, 24b of the mattress 10, a diameter of the recesses 52 decreases in the direction of the central transverse axis only in the shoulder support areas 24a, 24b, in particular gradually. The diameter of the recesses 52 can also decrease continuously in the direction of the central transverse axis 16 in the shoulder closure areas 24a, 24b. As a result, the corresponding depth of the recesses 52 also decreases step by step in the direction of the central transverse axis 16 in the shoulder closure areas 24a, 24b.

Each of the recesses 52 is open via an incision 54 in the direction of the second outer surface 42 , the incisions 54 extending parallel to the recesses 52 over the entire width of the mattress 10 . The recesses 52 are, as it were, connected to the second outer surface 42 via the incisions 54 . A thin material layer of material of the second mattress element 40 is thus located between each of the recesses 52 and the second outer surface 42, apart from the incisions 54. The recesses 52 are thus each covered, apart from the incisions 54, by a material layer of the second mattress element 40, so that the recesses 52 are not or hardly noticeable for a user located on the second outer surface 42 .

In the example of 2 the recesses 52 are formed at least partially in the head support areas 20a, 20b, the neck support areas 22a, 22b, the shoulder support areas 24a, 24b, the lumbar support areas 26a, 26b, and the pelvic support areas 28a, 28b of the first mattress element 30. In detail, a recess 52 with a T-shaped cross-sectional area is provided in each of the headrest regions 20a, 20b. Five recesses 52 with a circular cross-sectional area are provided in each of the shoulder support areas 24a, 24b. A recess 52 with a semi-circular cross-sectional area is provided in each of the lumbar support areas 26a and 26b. In the pelvic support areas 28a and 28b, three recesses 52 having a triangular cross-sectional area are provided together. The three triangular cross-sectional area recesses 52 in the pelvic support regions 28a and 28b differ at least partially in cross-sectional area. In other words, the two recesses 52a, which are spaced furthest from one another, are of identical design, but can also be of different design. These recesses 52a, which are spaced furthest from each other, differ from the last recess 52a, which is provided between the two recesses which are spaced furthest from each other. The recesses 52a which are spaced furthest from one another have a depth of 30 mm, or extend 30 mm into the interior volume of the second mattress element 40. The recesses 52a which are between the recesses which are spaced furthest from one another point a depth of 25 mm, or extend 25 mm into the inner volume of the second mattress element 40. The three recesses 52a are open towards or to the second outer surface 42 and form openings of 30 mm there. Alternatively, the recesses 52a with a triangular cross-sectional area can also extend into the second mattress element 40 with a range of 10 mm to 60 mm. Further, the cross section of the recesses 52a may increase or decrease stepwise or continuously.

No recesses 52 may be provided in the neck support portions 22a, 22b. However, more or fewer recesses 52 may be provided in each of the portions or halves 12a, 12b. The recesses 52 with a T-shaped cross-sectional area have an identical depth. The recesses 52 with a semi-circular cross-sectional area have an identical depth.

A dimension and/or a diameter of the recesses 52, 48 measured parallel to the longitudinal axis 14 of the mattress 10 can be between around 0.5 cm and 7 cm, in particular between 1 cm and 5 cm, for example.

Furthermore, the profiles 46, 50 and/or the recesses 48 and 52 can be arranged and/or formed symmetrically relative to the central axis 16 and/or the central transverse plane 17, in particular mirror-symmetrically.

By designing the profiles 46 and 50 of the first and second mattress element 30, 40, at least partially different support properties and/or compression hardnesses can advantageously be achieved in the areas 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b, 28a, 28b of the Mattress 10 are provided.

As further in the 2 As can be seen, the profile 46 of the first outer surface 32 of the first mattress element 30 differs at least partially from the profile 50 of the second outer surface 42 of the second mattress element 40. For example, there are more, the same number or fewer recesses 48 on the second outer surface 42 than on the first outer surface 32 is formed.

3 and 4 each show a mattress 10 according to exemplary embodiments. Unless otherwise described, the mattress 10 of 3 and 4 These live elements and features like the mattress 10's 1 and 2 on.

The mattress 10 has a mattress cover 60 which at least partially, in particular completely, encloses and/or envelops the first mattress element 30 and the second mattress element 40 .

The mattress cover 60 has a first or upper half 62 and a second or lower half 64, which at least partially has a zipper 66 along at least part of an outer circumference of the mattress 10, for example along the side surfaces and/or end faces of the mattress 10, are connectable to each other. The first half 62 of the mattress cover 60 can cover at least the first lying surface 32 and/or the first outer surface 32 of the first mattress element 30 . The second half 64 of the mattress cover 60 can cover at least the second lying surface 42 and/or the second outer surface 42 of the second mattress element 40 .

The mattress cover 60 can be opened via the closure 66 and completely removed, for example in order to wash the mattress cover 60. The mattress cover 60 can be washed in particular at a washing temperature of up to around 75° Celsius, for example up to around 60° Celsius, which can advantageously simplify and/or enable thorough cleaning of the mattress cover 60 .

The halves 62, 64 of the mattress cover 60 can differ, for example, with regard to a type of fabric and/or a fabric structure of the cover material used for the halves 62, 64. The covering material of the first half 62 of the mattress cover 60 can, for example, have one or more layers. For example, the cover material of the first half 62 of the mattress cover 60 can have an upper layer forming an outer material, which can serve as a support surface for the user. In addition, the cover material of the first half 62 of the mattress cover 60 can have a lower layer which can be at least partially in physical contact with the first outer surface 32 of the first mattress element 30 . A layer of wadding, such as a layer of polyester wadding and/or climate wadding, can optionally be arranged between the upper layer and the lower layer. As a result, the upholstery fabric can be given a pleasantly soft feel and a certain compressibility and/or volumization. The cover material of the first half 62 of the mattress cover 60 can also have honeycomb-like and/or honeycomb-shaped depressions 70, which can be arranged in the cover material, for example in a regular pattern. As an alternative to the indentations 70, the mattress cover 60 can have a pattern 70, similar to an embossing, at least in a partial area. The honeycomb-like depressions 70 can advantageously be used to fix the cotton layer between the upper layer and the lower layer. The cover material of the second half 64 of the mattress cover 60 can also be configured analogously and/or identically to the cover material of the first half 62 of the mattress cover 60 .

Alternatively, however, the cover material of the second or lower half 64 of the mattress cover 60 can differ from the cover material of the first or upper half 62 of the mattress cover 60, in particular with regard to a structure, a material type, a material composition and/or a material structure. For example, the cover material of the second half 64 of the mattress cover 60 can be siliconized and/or rubberized. For example, a layer of latex may be applied to an outer surface of the cover fabric of the second half 64 of the mattress cover 60 . In particular, this can prevent the mattress 10 from slipping on a support surface, such as a bed. This can be of particular advantage in the case of box-spring beds, since here the mattress 10 is regularly not held laterally by the boundary surfaces of the bed.

Optionally, the halves 62, 64 of the mattress cover 60 can differ in terms of a color of the cover material. This can enable the user to use the structure and/or color of the respective half 62, 64 of the mattress cover 60 to indicate which side and/or which of the first and second lying surfaces 32, 54 has the desired degree of firmness. The user can thus identify and/or select the lying surface 32, 54 that is suitable for him or her without removing the mattress cover 60, for example.

Optionally, the thickness of the two halves 62, 64 of the mattress cover 60 can be different. For example, the top/first half 62 may have a lesser thickness than the bottom/second half 64 . This can mean that the upper/first half 62 in the vertical direction of the mattress 10 covers a smaller part of the thickness of the mattress 10 than the lower/second half 64. In the example of FIG 4 the upper/first half covers about 1/3 of the thickness of the mattress 10 and the lower/second half covers about 2/3 of the thickness of the mattress 10. A 50/50 split or any other split is fundamentally conceivable.

Furthermore, the mattress cover 60 has two handles 65 on each side surface of the mattress 10, with the aid of which the mattress 10 can be transported. The carrying handles 65 can be made of a fabric, for example. For example, the carrying handles 65 can be made from the cover material of the first and/or second half 62, 64 of the mattress cover 60 and/or, for example, from a spacer fabric, as described above and below with reference to the cover material of the first and/or second half 62, 64 described. The carrying handles 65 can have a length measured parallel to the longitudinal axis 14 of around 15 cm to 25 cm. The carrying handles 65 can be attached to the first half 62 of the mattress cover 10 or, as in 4 shown, may be located on the second half 64 of the mattress cover. Carrying handles 65 can also be provided on both halves 62, 64.

As in 4 recognizable, the zipper 66 is not arranged in the middle, so that the first half 62 has a smaller thickness (or height—measured parallel to the vertical axis) than the second half 64 of the mattress cover 60 . As a result, the carrying handles 65 can be made wider and thus more mechanically stable. A width of the carrying handles measured parallel to the vertical axis of the mattress 10 can be around 2 cm to 5 cm. The arrangement of the zip fastener 66 can also indicate a degree of hardness of the respective lying surface 32, 54.

Alternatively, however, the zipper 66 can also be arranged in the middle, so that the halves 62, 64 of the mattress cover 60 can have essentially identical thicknesses and/or heights (measured parallel to the vertical axis).

Alternatively or in addition to the above with regard to the cover material of the first and second halves 62, 64 of the mattress cover 60, the mattress cover 60 can be produced at least partially, in particular completely, from a spacer knitted fabric, for example a three-dimensional spacer knitted fabric, with the mattress cover 60 (or The spacer fabric) on the outside (the side facing the user) has a honeycomb structure with outwardly open recesses. In this way, a breathable surface of the mattress 10 can advantageously be provided, which can further improve lying comfort for the user. A mattress cover 60 made from a knitted spacer fabric can also have an advantageous haptic effect, in particular compared to a mattress cover made from a knitted spacer fabric, so that the mattress cover 60 can feel soft and not scratchy. The honeycomb recesses can have elliptical cross sections, for example. However, any other cross sections, in particular round, oval, angular and/or polygonal cross sections, are also possible. The spacer knitted fabric can be multi-layered, in particular two-layered or three-layered. The first and second halves 62, 64 of the mattress cover 60 may generally be made of an identical fabric or of different fabrics.

Additionally, it should be noted that "comprising" and "having" do not exclude other elements, and "a" or "an" does not exclude a plurality. Furthermore, it should be pointed out that features that have been described with reference to one of the above exemplary embodiments can also be used in combination with other features of other exemplary embodiments described above. Any reference signs in the claims should not be construed as limitations.
