Description
- Futon mattresses generally have cushioning filler material encased in a protective cover. For example, some futon mattresses are filled with cotton batting, wool batting, foam, or the like to provide sufficient cushioning. However, due to the many uses for a futon cushion, the outer cover can become easily soiled. The cover of most conventional futon cushions can not be easily cleaned because the cover cannot be conveniently separated from the cushioning filler material.
- The present invention generally relates to a futon mattress having multiple pockets for storing filler material within the cover of the mattress. The filler material can be removed from the pockets and the cover to allow the cover to be easily laundered. In some embodiments, the top of the cover can be separated from the bottom of the cover to allow the top to be separately laundered.
- One embodiment of the invention relates to a futon mattress including a cover having a top portion coupled to a bottom portion and a closure device coupled to the cover to selectively allow access to inside surfaces of the top and bottom portions of the cover. A first plurality of pockets are positioned along an inside surface of the top portion of the cover and contain a filler material accessible only from inside the cover. A second plurality of pockets are positioned along an inside surface of the bottom portion of the cover and contain a filler material accessible only from inside the cover.
- Another embodiment relates to a futon mattress having a cover with a top portion selectively coupled to a bottom portion via a closure device positioned between the top portion and the bottom portion. The closure device is movable to selectively allow the top portion to uncouple from the bottom portion. The top portion of the cover has a first layer of pockets, while the bottom portion of the cover has a second layer of pockets. The first layer of pockets and the second layer of pockets are filled with a filler material.
- Another embodiment relates to a futon mattress having a cover with a top surface coupled to a bottom surface, where the top and bottom surface of the cover each have a length and a width. A zipper is positioned along the interface between the top surface and the bottom surface to selectively allow the top surface to uncouple from the bottom surface. A first plurality of pockets are positioned along an inside surface of the top of the cover and contain a first filler material accessible only from inside the cover. The first plurality of pockets are positioned side-by-side along the length of the top of the cover. A second plurality of pockets are positioned along an inside surface of the bottom of the cover and contain a second filler material accessible only from inside the cover. The second plurality of pockets are positioned side-by-side along the length of the bottom of the cover.

-
FIGS. 1-6 illustrate one embodiment of the present invention. As shown inFIGS. 1 and 2 , the illustrated mattress is adapted for use as a futon mattress. In other words, the mattress can be easily folded or otherwise manipulated to change the configuration of the mattress from a fully laid-out position, as illustrated inFIG. 2 , to a folded position, as illustrated inFIG. 1 . Manipulation of the mattress, as shown inFIG. 1 , can allow it to be easily stored or used for other purposes such as seating. - As best illustrated in
FIGS. 2 and 6 , the illustratedmattress 10 has a fabric case orcover 14 filled withfiller material 18. Thecover 14 contains and protects thefiller material 18. Thecover 14 has atop portion 22 coupled to abottom portion 26 along aperimeter 30. Thetop portion 22 can be coupled to the bottom portion via stitching, adhesive or cohesive bonds, and the like. Furthermore, aclosure device 34, such as a zipper, hook and loop fastener, and the like can be coupled to the mattress to allow selective access to the interior portions of themattress 10. Theclosure device 34 can form part of the coupling between thetop portion 22 and thebottom portion 26 of thecover 14. The access allowed bysuch closure devices 34 can be used to reconfigure or removefiller material 18 from thecover 14. With the filler material removed, thecover 14 can be easily laundered. - Since the
top portion 22 of themattress 10 is more likely to be soiled, it may be desirable in some situations to only launder thetop portion 22 of thecover 14 without laundering thebottom portion 26. Accordingly, in some embodiments, theclosure device 34 can form the entire coupling between thetop portion 22 andbottom portion 26 of thecover 14. In such embodiments, thetop portion 22 can be separated or uncoupled from thebottom portion 26 to be separately laundered, if desired. For example, as illustrated inFIGS. 2 and 3 , theclosure device 34 or zipper can be actuated to separate or uncouple thetop portion 22 of thecover 14 from thebottom portion 26 of thecover 14. - Although the illustrated embodiment shows that the
top portion 22 can be separated or uncoupled from thebottom portion 26 to remove thetop portion 22 from thebottom portion 26, other embodiments can allow these portions to be separated, but not removed from each other. For example, in some embodiments, thetop portion 22 can be coupled to thebottom portion 26 along a substantial portion ofperimeter 30 via aclosure device 34, while a seam or other substantially permanent connection is used to connect thetop portion 22 to the bottom portion along only a portion of theperimeter 30. In some embodiments, thetop portion 22 can be substantially permanently connected to thebottom portion 26 along at least one side or edge of thecover 14. Accordingly, in these alternative embodiments, thetop portion 22 can be separated from thebottom portion 26 such that it can be positioned on a support surface adjacent thebottom portion 26 to allow access to interior portions of thecover 14. - The
cover 14 can be made from many different materials. In some embodiments, thetop portion 22 of thecover 14 is formed from a first material, while thebottom portion 26 of thecover 14 is formed from a second material. For example, thetop portion 22 of thecover 14 can have a relatively soft velour feel, while thebottom portion 26 of thecover 14 can be made from a non-slip material. However, in other embodiments, both thetop portion 22 and thebottom portion 26 of thecover 14 are made from the same type of material. - As illustrated in
FIGS. 3-6 , thecover 14 includesmultiple pockets filler material 18. A first plurality ofpockets 38 are connected to thetop portion 22 of thecover 14. The first plurality ofpockets 38 are arranged in a layer or positioned side-by-side along thetop portion 22 of thecover 14 to substantially cover the entire length L of thecover 14. Each pocket within the first plurality ofpockets 38 extends substantially across the width W of thecover 14. In other constructions, however, two or more pockets can extend across the width W of thecover 14. For example, it may be desirable in some embodiments to provide different levels of cushioning on each side of the mattress corresponding to a specific user's desire. - Each illustrated pocket within the first plurality of
pockets 38 is shown as fully enclosingfiller material 18 within the pocket. Each illustrated pocket within the first plurality ofpockets 38 also has aclosure device 46 to fully contain thefiller material 18 within the pocket, prevent thefiller material 18 from unintentionally escaping the pocket, and allow selective access within the pocket. As illustrated, thepocket closure device 46 can be a zipper, but in other embodiments, it can include hook and loop fasteners and the like. The illustratedpocket closure device 46 is positioned on a surface of each pocket that is only accessible from inside the cover. In other words, thecover closure device 34 must be opened prior to being able to access and manipulate thepocket closure device 46. As illustrated inFIGS. 3 and 5 , thepocket closure device 46 can be located on asurface 50 of each pocket that is substantially parallel to thetop surface 22 of thecover 14. With this construction, thepocket closure device 46 is positioned beneath thefiller material 18 when themattress 10 is used in the unfolded position. Accordingly, the chance that thepocket closure device 46 will be felt by a person resting on the mattress is reduced. Although the illustrated embodiment shows thepocket closure device 46 extending across the bottom surface 50 (as shown inFIG. 6 ) of the pocket, in other embodiments, the closure device can be positioned around at least a portion of the perimeter of each pocket. - Although the illustrated embodiment has a
pocket closure device 46 on each pocket of the first plurality ofpockets 38, in other embodiments, aclosure device 46 is not used. For example, each pocket can be constructed to fully enclose thefiller material 18 without sealing theopening 54 of the pocket. Specifically, theopening 54 of the pocket can have overlapping pieces of fabric that prevent thefiller material 18 from unintentionally escaping the pocket. Furthermore, assuming that each pocket is properly sized for thefiller material 18, the pocket would not have to fully enclose thefiller material 18. Rather, it could merely enclose the perimeter of thefiller material 18. - As illustrated in
FIGS. 3 , 4, and 6, the futon mattress also has a second plurality ofpockets 42 that are connected to thebottom portion 26 of thecover 14. The second plurality ofpockets 42 are arranged in a layer or positioned side-by-side along thebottom portion 26 of thecover 14 to substantially cover the entire length L of thebottom portion 26 of thecover 14. Each pocket within the second plurality ofpockets 42 extends substantially across the width W of thecover 14. However, in other constructions, two or more pockets can extend across the width W of thecover 14. For example, it may be desirable in some embodiments to provide different levels of cushioning on each side of the mattress corresponding to a specific user's desire. - Unlike the first plurality of
pockets 38 which are shown as being fully enclosed, the illustrated second plurality ofpockets 42 do not fully enclose thefiller material 18 within each pocket. Rather, each pocket within the second plurality ofpockets 42 merely enclose the perimeter of thefiller material 18 to prevent movement of thefiller material 18 within themattress 10. However, other embodiments can fully enclose thefiller material 18 if desired. For example, it may be desirable to fully enclose thefiller material 18 when aloose filler material 18, such as granular or shredded foam, foam beads, loose cotton, and the like is used within the second plurality ofpockets 42. Accordingly, some constructions may also use apocket closure device 46 as well to fully contain thefiller material 18 and prevent thefiller material 18 from unintentionally escaping the pocket. Like the first plurality ofpockets 38, thepocket closure device 46 can be positioned on a surface of each pocket that is only accessible from inside thecover 14. - As shown in the illustrated embodiment, each of the pockets in the second plurality of
pockets 42 has afabric lip 58 that extends around one surface of the pocket to engage the perimeter of thefiller material 18, such as a block of foam. Thefabric lips 58 extend in a direction substantially parallel to the top andbottom surfaces cover 14. Furthermore, anopening 54 defined by thelips 58 is accessible only from inside thecover 14. - Although the illustrated embodiment shows each pocket within the same plurality of pockets has having the same construction, in other embodiments, one or more pockets within the same plurality of pockets can have a different construction relative to the other pockets within the same plurality of pockets. For example, one or more pockets within the second plurality of
pockets 42 can be fully enclosed while the remainder of the pockets utilize thelip 58 construction described above. Similarly, one or more pockets of the first plurality ofpockets 38 can utilize a non-fully enclosed structure while the remainder of the pockets are fully enclosed. - As illustrated in
FIGS. 2 , 3, and 6, the first and second plurality ofpockets pockets 38 includes seven pockets and the second plurality ofpockets 42 includes four pockets. Accordingly, as illustrated, two pockets of the first plurality ofpockets 38 are generally provided for each pocket of the second plurality ofpockets 42. Due to this arrangement, the end of certain pockets within the each of the plurality of pockets generally align to form a convenient fold location for thefuton mattress 10. However, in some embodiments, the ends of pockets do not need to align to form fold locations. Furthermore, the size and number of pockets within each plurality ofpockets - Although some pockets are illustrated as having equal lengths, the length of each pocket does not have to be the same. Rather, the length can vary depending upon the location of the pocket on the
mattress 10. For example, some mattresses are divided into zones that correspond with locations of different areas of the body. Accordingly, the pockets can have different lengths corresponding to the desired size of several zones on the mattress. For example, an average person's hips will generally fall within a predetermined area on the mattress and need to sink into the mattress more than the small of the back to properly align the spine. Thus, a zone having a select length andfiller material 18 characteristics can be positioned in this area. The adjacent zones can have different lengths and/orfiller material 18 characteristics to properly align the back and legs with the hips. - As described above, each pocket is designed to at least partially contain a
filler material 18, which provides a cushioning effect for themattress 10. Thefiller material 18 can include a wide variety of cushioning materials. For example, thefiller material 18 of themattress 10 can include cotton batting, wool batting, foam such as viscoelastic foam, polyurethane foam, highly resilient (HR) foam, or other foams commonly used in the industry, and the like. The selection of materials can depend upon the desired feel of the mattress. Furthermore, the filler material can be formed as blocks, strips, or webs, or it can be placed in the pockets in a loose or granular form. Additionally, a combination of different filler material types and forms can be used in a single pocket. - The
filler material 18 of each pocket can be individually selected to provide a desired feel in themattress 10. Accordingly, one or more of the pockets can be filled with the same material or one or more pockets can be filled with different materials. In the illustrated embodiment, the first plurality ofpockets 38 are filled with a first type offiller material 18 and the second plurality ofpockets 42 are filled with a second type offiller material 18. More specifically, the first plurality ofpockets 38 are filled with a first type of foam and the second plurality ofpockets 42 are filled with a second type of foam. The first type of foam is a viscoelastic foam sold by Tempur World, LLC of Lexington, Ky., U.S.A. under the trademark Tempur®. The second type of foam is a highly resilient foam. In possible alternative embodiments, each first plurality of pockets and/or each second plurality of pockets is filled with a combination of two or more types of foam, however, one type of foam being the primary type of foam in the pocket in question. It will also be possible filling selected first pockets with one type of foam or with more types of foam, and filling remaining first pockets with another type of foam or with other more types of foam. The same possibility applies to selected second pockets and remaining second pockets. - As illustrated in
FIGS. 3 and 4 , foam filler material is formed as strips or blocks. These strips are covered by a nettingmaterial 62 or other fabric and inserted into the pockets of thecover 14. The netting 62 can help to protect the foam when being inserted and removed from the pockets. Additionally, depending upon the type of material used for the netting 62, the netting 62 can control the amount of sheer force or friction force between the pockets and the filler material. For example, it may be desirable to use a material that reduces the sheer force to allow easier movement between the filler material and the pocket. This can reduce the effort needed to insert and remove thefiller material 18 from the pockets. However, in some embodiments, a material with a greater sheer force can be selected to reduce the amount and/or ease of movement of the filler material within the pocket. - As illustrated, the foam blocks are roughly the same size as the pockets. However, the foam can be made slightly larger or smaller than the size of the pockets. For example, in some embodiments the pockets are designed to fit snuggly over the foam to provide a firm feel. In other embodiments, the pockets are not as snug to provide a softer feel.
- The embodiments described above and illustrated in the figures are presented by way of example only and are not intended as a limitation upon the concepts and principles of the present invention. As such, it will be appreciated by one having ordinary skill in the art that various changes in the elements and their configuration and arrangement are possible without departing from the spirit and scope of the present invention. For example, some embodiments of the invention have been described with reference to specific types of filler material, such as highly resilient foam and visco-elastic foam. However, the type and shape of the filler material may be different, without departing from the scope of protection. Furthermore, some embodiments referenced a specific pocket construction in specific locations on the mattress. The specific construction of the pocket relative to the location of the pocket can vary without departing from the scope of protection.
- Variations and modifications of the foregoing embodiments are within the scope of the present invention. It is understood that the invention disclosed and defined herein extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. For example, various alternatives to the certain features and elements of the present invention are described with reference to specific embodiments of the present invention. With the exception of features, elements, and manners of operation that are mutually exclusive of or are inconsistent with each embodiment described above, it should be noted that the alternative features, elements, and manners of operation described with reference to one particular embodiment are applicable to the other embodiments. All of these different combinations constitute various alternative aspects of the present invention.
