Description

The present disclosure relates to bedding conditioners.

Japanese Unexamined Patent Publication No. 2001-169887 describes a height-adjustable pillow. In this pillow, a required number of height-adjusting sheets are stacked on top of the main body of the pillow, and the tops are covered with a cover. The covering has a rectangular shape. The covering is attached to the main body of the pillow so as to be wrapped around the main body, and is joined to the main body while being wrapped around the main body. A hook-and-loop fastener is arranged on one side of the covering and on each of the lower surface of the main body. The covering is wound around the main body and joined to the main body via the hook-and-loop fastener. In this way, the height of the pillow is adjusted by wrapping the cover around the main body on which one or more sheets are placed.

Japanese Patent Application Publication No. 2001-169887

In the pillow described above, since the sheet body is placed on the upper surface of the main body of the bedding (pillow), the position of the sheet body may shift during use of the bedding. Furthermore, bedding on which the user's body is placed is required to be able to easily adjust the height and softness of the bedding. However, in this bedding, the height is adjusted by stacking a plurality of sheets and further wrapping the covering around the main body. Therefore, when making such adjustments, it is necessary to remove the cover from the main body and adjust the number of sheets while exposing the main body or the upper part of the sheet body, and the work of adjusting the height of the bedding is required. is troublesome. Furthermore, in this bedding, the height is adjusted by adjusting the number of sheets placed over the entire bedding, so it is difficult to partially adjust the height and softness of the bedding.

An object of the present disclosure is to provide a bedding adjuster that can suppress misalignment and easily and partially adjust the height and softness of bedding.

The bedding adjuster according to the present disclosure is a bedding adjuster that is attached to bedding placed on a placement surface. The bedding has a front surface on which the user's body rests and a back surface located behind the front surface. The bedding adjuster includes a mat part arranged on the surface and extending in one direction, and a belt part connected to both ends of the mat part in one direction. In a state where the mat portion is placed on the front surface, the belt portion is placed between the placement surface and the back surface.

In the bedding adjuster according to the present disclosure, the belt portion is arranged between the placement surface on which the bedding is placed and the back surface. Thereby, the belt portion is sandwiched and fixed between the placement surface and the back surface, so that displacement of the bedding adjuster can be suppressed. Moreover, in this bedding adjuster, the bedding adjuster is attached to the bedding by placing the belt portion between the placement surface and the back surface of the bedding in a state where the mat portion is placed on the surface of the bedding. Therefore, the bedding adjuster can be easily attached to and removed from the bedding. With the mat section placed on the surface of the bedding, the belt section is placed between the placement surface and the back surface of the bedding, thereby moving the mat section along the surface of the bedding and moving it along the back surface of the bedding. This makes it possible to move the belt part. Therefore, since the mat portion can be easily moved to the area where the height and softness are desired to be adjusted, the height and softness of the bedding can be easily and partially adjusted. Since the belt part is placed between the placing surface and the back surface while the mat part is placed on the surface of the bedding, the belt part may be caught between the placing surface and the back surface, causing unintended damage to the belt part. Movement can be suppressed. Therefore, it is possible to suppress misalignment of the bedding adjuster.

The belt portion may be a pair of band-shaped members extending in one direction from both ends of the mat portion in one direction. At least one of the pair of band-shaped members may include a fixing member that allows one band-shaped member to be attached to and removed from the other band-shaped member. The pair of band-shaped members may be fixed to each other via a fixing member. In this case, a pair of belt-like members, which are belt parts, extend from both ends of the mat part in one direction, and at least one belt-like member is arranged between the bedding placement surface and the back surface of the bedding. Then, at least one strip member extends from one end of the back surface of the bedding to the other end. Therefore, since the bedding is wound around the pair of belt-like members, unintended movement of the belt portion can be more reliably suppressed. A pair of band-like members extending from both ends of the mat portion in one direction are removably fixed to each other via a fixing member. With this fixing member, the pair of band-like members can be more firmly fixed to the bedding, and the mat portion can be easily moved to a desired location on the bedding by removing the fixing member.

The fixing member includes a first fixing member provided on one of the pair of band-like members and a second fixing member provided on the other of the pair of band-like members, and the fixing member includes a first fixing member provided on one of the pair of band-like members, and a second fixing member provided on the other of the pair of band-like members. The length may be longer than the length of the second fixing member in one direction. In this case, the fixing position of the second fixing member relative to the first fixing member can be changed along the one direction. As a result, the length of the pair of band-shaped members wound around the bedding can be freely changed, so that the bedding adjuster can be attached to bedding of various sizes.

The first fixing member may be a loop of a hook-and-loop fastener, and the second fixing member may be a hook of the hook-and-loop fastener that engages with the loop. The length in one direction in the loop may be longer than the length in one direction in the hook. In this case, the second fixing member can be fixed to the first fixing member by adjusting the position in one direction and bringing the hook into contact with the loop having a longer length in one direction. Therefore, compared to fixing means other than hook-and-loop fasteners, the pair of band-like members can be attached and detached more easily. Also, the hook of a hook-and-loop fastener does not feel as good to the touch as compared to a loop. However, if the loop is longer than the hook, the entire hook can be hidden when the hook is joined to the loop. Therefore, it is possible to maintain a state in which the skin feels good.

According to the present disclosure, positional displacement can be suppressed, and the height and softness of the bedding can be easily and partially adjusted.

Hereinafter, embodiments of a bedding adjuster according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant description will be omitted as appropriate. In addition, some parts of the drawings may be simplified or exaggerated for ease of understanding, and the dimensional ratios and the like are not limited to those shown in the drawings.

First, the bedding to which the bedding adjuster according to the present disclosure is attached will be described. "Bedding" refers to something that the user's body rests on when the user rests or sleeps. "Bedding" typically includes bedclothes such as mattresses and mattresses, cushions, bed pads, cushions, or pillows. "Bedding" is used by being placed on a placing surface. "Placement surface" is a surface on which bedding is placed (mounted). As an example, the "placement surface" is a floor surface. "Bedding" has a front surface on which the user's body rests, and a back surface located behind the front surface. In other words, the "bedding" is placed on the placement surface so that the back surface is in contact with the placement surface, and the user's body is placed on the surface of the bedding.

A "user" is a person who uses the bedding by bringing his or her body into contact with the bedding. For example, when the bedding is a bedclothes, the "user" is a person who places his or her body on the bedding. In this case, as a specific example, the "user" is a person lying on the purchased bedding or a person lying on the bedding for purchase. In this embodiment, a worker adjusts the height and softness of the bedding by attaching a bedding adjuster to the bedding. The "worker" is, for example, a person who attaches bedding adjusters to bedding. A "worker" is typically a user, a person who purchased bedding, or a person who sells bedding.

[Composition of bedding adjuster]
FIG. 1 is a schematic plan view showing a bedding adjuster 1 according to an embodiment. The bedding adjuster 1 is attached to the bedding placed on the placement surface to partially adjust the height and softness of the bedding. As shown in FIG. 1, the bedding adjuster 1 has a shape extending in one direction (left-right direction in FIG. 1). The bedding adjuster 1 includes a mat portion 2 and a belt portion 3.

A part of the user's body is placed on the mat portion 2. The mat portion 2 is placed on the surface of the bedding and is used to adjust the height and softness of the bedding. In this embodiment, the mat portion 2 has a rectangular shape with long sides extending in one direction. For example, the mat portion 2 has a flat shape. The mat portion 2 has long sides 2a, 2b and short sides 2c, 2d. Hereinafter, the direction in which the long sides 2a and 2b of the mat portion 2 extend is referred to as a longitudinal direction D1, and the direction in which the short sides 2c and 2d of the mat portion 2 extend is referred to as a lateral direction D2. In this embodiment, the longitudinal direction D1 of the mat portion 2 coincides with "one direction" which is the direction in which the bedding adjuster 1 extends.

The mat portion 2 is configured, for example, by housing a cushioning material in a bag body (side fabric). The bag is made of cloth, for example. The cushioning material is, for example, high resilience urethane, low resilience urethane, fibrous network, honeycomb, latex, solid cotton, profiled urethane, beads, pipes, buckwheat hulls, low resilience chips, or polyester cotton. Further, the cushioning material may be constructed by combining a plurality of these materials. The types of the bag and the cushioning material can be changed as appropriate.

For example, when the bedding to which the bedding adjuster 1 is attached has a rectangular shape in plan view, the length of the mat portion 2 in the longitudinal direction D1 may be the same as the length of the bedding in the lateral direction. However, the length of the mat portion 2 in the longitudinal direction D1 may be longer than the length of the bedding in the lateral direction, or may be shorter than the length of the bedding in the lateral direction. When the length of the mat portion 2 in the longitudinal direction D1 is greater than or equal to the length of the bedding in the lateral direction, the mat portion 2 can cover the entire length of the bedding in the lateral direction.

The length of the mat portion 2 in the longitudinal direction D1 is, for example, 20 cm or more and 200 cm or less. Further, the length of the mat portion 2 in the lateral direction D2 is, for example, 10 cm or more and 70 cm or less. The thickness of the mat portion 2 (the length in the direction orthogonal to both the longitudinal direction D1 and the lateral direction D2) is, for example, 0.5 cm or more and 3 cm or less.

Examples of the material and dimensions of the mat portion 2 have been described above. However, the material and dimensions of the mat portion 2 are not limited to the above examples. For example, multiple types of bedding adjusters 1 having mat portions 2 having mutually different softness (hardness) may be prepared. Moreover, a plurality of types of bedding adjusters 1 having mat portions 2 having mutually different dimensions (area or thickness in plan view) may be prepared. In this way, a plurality of bedding adjusters 1 having different types of mat portions 2 may be selectable. In this case, it becomes possible to select a desired bedding adjuster 1 according to the user's preference or physical properties.

The belt portion 3 is a portion for attaching the bedding adjuster 1 to bedding. For example, the belt portion 3 is a portion on which the user's body cannot be placed. The belt portion 3 is connected to both ends of the mat portion 2 in the longitudinal direction D1. In this embodiment, the belt portion 3 is band-like members 4 and 5 extending in the longitudinal direction D1 from both ends of the mat portion 2 in the longitudinal direction D1. Each of the strip members 4 and 5 has a flat shape. Further, each of the band members 4 and 5 has an isosceles trapezoid shape. The length of each of the strip members 4 and 5 in the lateral direction D2 becomes shorter as the distance from the mat portion 2 increases.

The strip member 4 has a lower base side 4a and an upper base side 4b shorter than the lower base side 4a. For example, the lower base side 4a extends substantially parallel to the upper base side 4b. The strip member 4 has opposite sides 4c and 4d that connect the lower base side 4a and the upper base side 4b. The opposite sides 4c and 4d correspond to the legs of the trapezoidal band member 4. For example, the length of the opposite side 4c is equal to the length of the opposite side 4d.

The lower base side 4a of the strip member 4 is connected to the short side 2c of the mat portion 2. As an example, the strip member 4 is sewn to the mat portion 2. In this embodiment, the length of the lower base side 4a of the strip member 4 is shorter than the length of the short side 2c of the mat portion 2. However, the length of the lower base side 4a may be equal to the length of the short side 2c, or may be longer than the length of the short side 2c. The length of the lower base 4a of the strip member 4 is, for example, 10 cm or more and 70 cm or less.

The shape and size of the strip member 5 may be the same as the shape and size of the strip member 4. For example, the strip member 5 has a lower base side 5a and an upper base side 5b shorter than the lower base side 5a. For example, the lower base side 5a extends substantially parallel to the upper base side 5b. The strip member 5 has opposite sides 5c and 5d that connect the lower base side 5a and the upper base side 5b.

The lower base side 5a of the strip member 5 is connected to the short side 2d of the mat portion 2. As an example, the strip member 5 is sewn to the mat portion 2. In this embodiment, the length of the lower base side 5a of the strip member 5 is shorter than the length of the short side 2d of the mat portion 2. However, the length of the lower base side 5a may be equal to the length of the short side 2d, or may be longer than the length of the short side 2d.

Each of the band members 4 and 5 is made of, for example, a stretchable mesh material. In this case, since the belt-like members 4 and 5 are expandable and contractible, the bedding adjuster 1 can be moved more easily, and the breathability of the belt-like members 4 and 5 can be improved. However, the material constituting the band members 4 and 5 can be changed as appropriate, does not have to be expandable and contractible, and is not particularly limited. Further, the shape of the band members 4 and 5 may be, for example, rectangular, and is not limited to the isosceles trapezoid shape.

For example, the length of each of the strip members 4 and 5 in the longitudinal direction D1 is shorter than the length of the mat portion 2 in the longitudinal direction D1 (namely, the length of the long sides 2a and 2b). For example, the length of the strip member 4 in the longitudinal direction D1 and the length of the strip member 5 in the longitudinal direction D1 are the same. The length of each of the strip members 4 and 5 in the longitudinal direction D1 is, for example, 20 cm or more and 200 cm or less. For example, the bedding adjuster 1 is attached to the bedding so as to wrap around the bedding. The lengths of the strip members 4 and 5 in the longitudinal direction D1 may be different from each other as long as they can be wrapped around the bedding.

Each of the strip members 4 and 5 has a fixing member 6. The fixing member 6 allows the strip member 4 to be attached to and removed from the strip member 5. The band members 4 and 5 are fixed to each other via a fixing member 6. The fixing member 6 includes a first fixing member 61 provided on the strip member 4 and a second fixing member 62 provided on the strip member 5.

FIG. 2 is a plan view showing the fixing member 6 of FIG. 1. As shown in FIG. 2, the first fixing member 61 is, for example, a loop 63 (female) of a hook and loop fastener. In this embodiment, the loop 63 has a rectangular shape. For example, the loop 63 has a rectangular shape with long sides extending in the longitudinal direction D1. However, the shape of the loop 63 is not particularly limited. In this embodiment, the loop 63 is provided at the end of the strip member 4 in the longitudinal direction D1 (on the upper base side 4b side of the strip member 4). The loop 63 is, for example, sewn to the band member 4.

The second fixing member 62 is a hook 64 (male) of a hook-and-loop fastener that is engaged with the loop 63 . In this embodiment, the hook 64 has a rectangular shape. For example, the hook 64 has a rectangular shape with long sides extending in the longitudinal direction D1. However, the shape of the hook 64 is not particularly limited.

In this embodiment, the hook 64 is provided at the end of the strip member 5 in the longitudinal direction D1 (on the upper base side 5b side of the strip member 5). The hook 64 is, for example, sewn onto the band member 5. For example, the length A1 of the loop 63 (first fixing member 61) in the longitudinal direction D1 is longer than the length A2 of the hook 64 (second fixing member 62) in the longitudinal direction D1. For example, the length of the hook 64 in the lateral direction D2 is approximately the same as the length of the loop 63 in the lateral direction D2.

[How to use bedding adjuster]
Next, a method of using the bedding adjuster 1 according to this embodiment will be described using FIGS. 3 and 4. Below, a mattress 10 will be illustrated as an example of bedding to which the bedding adjuster 1 according to the present embodiment is attached. FIG. 3 is a perspective view showing the surface 10a of the mattress 10 to which the bedding adjuster 1 is attached. FIG. 4 is a perspective view showing the back surface 10b of the mattress 10 to which the bedding adjuster 1 is attached.

As shown in FIGS. 3 and 4, the mattress 10 according to this embodiment is placed on a placement surface S. As shown in FIGS. As an example, the mounting surface S is a floor surface. The mattress 10 has long sides extending in the longitudinal direction D3 and short sides extending in the lateral direction D4. The mattress 10 has a surface 10a on which the user's body rests, and a back surface 10b located behind the surface 10a. In this embodiment, the mattress 10 has a rectangular shape in plan view. The mattress 10 includes, for example, a side fabric 11 and a cushion body (not shown) housed inside the side fabric 11.

In this embodiment, the side material 11 is constituted by bags 12, 13, and 14 divided in the longitudinal direction of the mattress 10. For example, the bag 12 is a part on which the user's head is placed, the bag 13 is a part on which the user's buttocks are placed, and the bag 14 is a part on which the user's legs are placed. Each of the bags 12, 13, and 14 (hereinafter sometimes simply referred to as a "bag") accommodates the cushioning material described above.

A folded portion 15 is formed between adjacent bags in the side fabric 11. The folded portion 15 is formed by the side fabric 11 that connects the adjacent bags. The bent portion 15 extends along the lateral direction D4 of the mattress 10. Thereby, for example, the user of the mattress 10 can fold the mattress 10 via the folding portion 15.

In this embodiment, the mattress 10 has a plurality of folded portions 15. Therefore, the mattress 10 can be folded via each folding portion 15. As an example, since the mattress 10 has two folding portions 15, it can be folded into three. However, the number of bent portions 15 is not particularly limited. As an example, the side fabric 11 may be constituted by one bag body having a rectangular shape in plan view. In this case, the bent portion 15 is not formed.

When attaching the bedding adjuster 1 to the mattress 10, an operator first places the mat portion 2 of the bedding adjuster 1 on the surface 10a of the mattress 10. For example, as shown in FIG. 3, the operator places the mat section 2 on the surface 10a of the mattress 10 with the longitudinal direction D1 of the mat section 2 aligned with the transverse direction D4 of the mattress 10.

In this embodiment, the operator places the mat portion 2 on the surface 10a of the mattress 10 on the portion where the bag 13 is formed. As mentioned above, as an example, the length of the mat portion 2 in the longitudinal direction D1 is the same as the length of the mattress (bedding) 10 in the transverse direction D4. In this case, in a state where the mat portion 2 is placed on the surface 10a of the mattress 10, the mat portion 2 is placed over the entire width direction D4 of the mattress 10.

The operator may place the mat portion 2 on the surface 10a of the mattress 10 on the portion where the bags 12 and 14 are formed. In this way, the position of the bedding adjuster 1 (mat part 2) in the longitudinal direction D3 of the mattress 10 can be changed according to the preference of the operator (user). The operator places the mat portion 2 at a portion of the mattress 10 where the height and softness are desired to be adjusted. The position where the mat portion 2 is placed is not particularly limited, but is appropriately selected depending on, for example, the shape of the user's body, the distribution of body pressure, etc. As an example, the mat portion 2 may be placed on the mattress 10 at a position on which the shoulders, hips, backs of knees, calves, or heels of the user are placed.

Subsequently, as shown in FIG. 4, the operator places the strip members 4 and 5 on the back surface 10b of the mattress 10 with the mat portion 2 placed on the front surface 10a of the mattress 10. The operator locks the hook 64 (second fixing member 62) of the strip member 5 to the loop 63 (first fixing member 61) of the strip member 4. Thereby, the band members 4 and 5 are fixed to each other via the fixing member 6. As mentioned above, as an example, the lengths of the strip members 4 and 5 in the longitudinal direction D1 are the same. In this case, the band members 4 and 5 are fixed to each other approximately at the center of the back surface 10b of the mattress 10 in the transverse direction D4.

Subsequently, the operator places the mattress 10 on the placement surface S so that the back surface 10b is in contact with the placement surface S. Thereby, in a state where the mat portion 2 is placed on the front surface 10a, the belt portion 3 is placed between the placement surface S and the back surface 10b. That is, the belt portion 3 is in a state of being sandwiched between the mounting surface S and the back surface 10b. Through the above steps, the bedding adjuster 1 is attached to the mattress 10 so as to be wrapped around it.

Next, the effects of the bedding adjuster 1 according to this embodiment will be explained. In the bedding adjuster 1, the belt portion 3 is arranged between the placement surface S on which the mattress 10 is placed and the back surface 10b. Thereby, since the belt part 3 is fixed by being sandwiched between the placement surface S and the back surface 10b, it is possible to suppress misalignment of the bedding adjuster 1. In addition, in this bedding adjustment tool 1, in a state where the mat portion 2 is placed on the front surface 10a of the mattress 10, the belt portion 3 is placed between the placement surface S and the back surface 10b of the mattress 10, thereby adjusting the bedding. A device 1 is attached to a mattress 10. Therefore, the bedding adjuster 1 can be easily attached to and detached from the mattress 10.

With the mat section 2 disposed on the surface 10a of the mattress 10, the belt section 3 is disposed between the placement surface S and the back surface 10b of the mattress 10, so that the mat section 2 is disposed along the surface 10a of the mattress 10. 2, it becomes possible to move the belt portion 3 along the back surface 10b of the mattress 10. Furthermore, this bedding adjuster 1 does not require any equipment, tools, etc. when it is attached to (or removed from) the mattress 10. Therefore, since the mat portion 2 can be easily moved to a portion where the height and softness are desired to be adjusted, the height and softness of the mattress 10 can be easily and partially adjusted. Since the belt portion 3 is placed between the placement surface S and the back surface 10b while the mat portion 2 is placed on the front surface 10a of the mattress 10, the belt portion 3 is placed between the placement surface S and the back surface 10b. By being pinched, unintended movement of the belt portion 3 can be suppressed. Therefore, displacement of the bedding adjuster 1 can be suppressed.

The belt portion 3 is a pair of band-like members (band-like members 4 and 5) extending in the longitudinal direction D1 from both ends of the mat portion 2 in the longitudinal direction D1. The band members 4 and 5 have a fixing member 6 that allows the band member 4 to be attached to and removed from the band member 5. The band members 4 and 5 are fixed to each other via a fixing member 6. In this case, belt-like members 4 and 5, which are belt parts 3, extend from both ends of the mat part 2 in the longitudinal direction D1, and each of the belt-like members 4 and 5 covers the mounting surface S of the mattress 10 and the back surface 10b of the mattress 10. placed between. Then, the belt-like members 4 and 5 extend from one end of the mattress 10 in the lateral direction D4 to the other end. Therefore, unintended movement of the belt portion 3 can be suppressed more reliably.

A pair of band-like members 4 and 5 extending from both ends of the mat portion 2 in the longitudinal direction D1 are removably fixed to each other via a fixing member 6. This fixing member 6 allows the belt-like members 4 and 5 to be more firmly fixed to the mattress 10, and also allows the mat portion 2 to be easily moved to a desired location on the mattress 10 by removing the fixing member 6.

As shown in FIG. 2, the fixing member 6 includes a first fixing member 61 provided on the strip member 4 and a second fixing member 62 provided on the strip member 5. The length A1 of the longitudinal direction D1 is longer than the length A2 of the second fixing member 62 in the longitudinal direction D1. In this case, the fixing position of the second fixing member 62 relative to the first fixing member 61 can be changed along the longitudinal direction D1. This makes it possible to freely change the length of the strip members 4 and 5 that are wrapped around the mattress 10, that is, the length of the portion of the strip members 4 and 5 that is wrapped around the bedding. It becomes possible to attach the bedding adjuster 1 to the bed.

The first fixing member 61 is a loop 63 of a hook-and-loop fastener, and the second fixing member 62 is a hook 64 of a hook-and-loop fastener that is engaged with the loop 63. The length A1 of the loop 63 in the longitudinal direction D1 is longer than the length A2 of the hook 64 in the longitudinal direction D1. In this case, the second fixing member 62 can be fixed to the first fixing member 61 by adjusting the position in the longitudinal direction D1 and bringing the hook 64 into contact with the loop 63 having a longer length in the longitudinal direction D1. Therefore, compared to fixing means other than hook-and-loop fasteners, the strip members 4 and 5 can be attached and detached more easily. Furthermore, the hook 64 of the hook and loop fastener is not as comfortable to the touch as the loop 63. However, if the loop 63 is longer than the hook 64, the entire hook 64 can be hidden when the hook 64 is joined to the loop 63. Therefore, it is possible to maintain a state in which the skin feels good.

Moreover, the bedding adjuster 1 according to the present embodiment includes a mat portion 2 and a belt portion 3 that have a flat shape. Therefore, when the bedding adjuster 1 is not in use, the operator can roll the bedding adjuster 1 in one direction as shown in FIG. Further, the rolled up bedding adjuster 1 may be able to be stored in a storage bag. When storing the mattress 10 described above in a closet or the like, for example, the operator folds the mattress 10 into three. At this time, even if the mattress 10 is folded without removing the bedding adjuster 1 from the mattress 10, the bedding adjuster 1 is less likely to interfere with storing the mattress 10 because the bedding adjuster 1 is thin.

[Example]
Examples of the bedding adjuster according to the present disclosure will be described below. Note that the present invention is not limited to the contents of the following examples. Below, the evaluation test results of the bedding adjuster 1 according to this embodiment will be explained using FIGS. 6 and 7. In this evaluation test, first, a profile mattress and a synthetic fiber firm cotton mattress were prepared as bedding to which the bedding adjuster 1 was attached. Furthermore, in this evaluation test, a low-resilience bedding adjuster and a high-resilience bedding adjuster were prepared as the bedding adjuster 1.

Profile mattresses are constructed by housing profiled urethane foam in a bag-like side fabric. The side fabric has an outer fabric (100% polyester) on which the user's body rests, a lining (100% polyester) located on the back side of the outer fabric, and a gusset (100% polyester) that connects the outer fabric and the lining to each other. ing. The lining and gusset are made of honeycomb mesh.

A profile mattress has a rectangular shape in plan view.
