Abstract
Description
- The present invention relates generally to the field of mattresses, and, more particularly, to mattress toppers.
- An unfortunate aspect of mattresses is their limited lifespan. The ability of a mattress to provide adequate support for a back and for other flexible regions of a body degrades continuously, beginning with the first use of a mattress. Initial resiliency and planarity may be lost due to use or to degradation of the materials comprising the mattress.
- Although use of a mattress may be prolonged at the price of increasing discomfort for a user, at some point, degradation of mattress support for the user becomes sufficiently severe for replacement of the mattress to be necessary. Further incentive for replacement is accumulation of stains on the mattress top. Acting as a disincentive for replacement is the cost of a replacement mattress, which may be several hundreds of dollars.
- One approach to extend the usable life of a mattress is to employ a mattress topper, a piece of foam having the same lateral dimensions as the mattress and enclosed in a fabric bag. The corners of the mattress topper may be attached to the corners of the mattress to hold the mattress topper in place.
- Such a prior art mattress topper lacks the performance of the mattress that it covers. The mattress topper may move with respect to the underlying mattress during use. The mattress topper may not restore the combination mattress topper-mattress to the performance of the mattress in its initial state. Stained areas may still be visible. Further, the combination may not have the fit and feel of a new mattress. The edge may not maintain its shape if sat upon by the user.
- For the above reasons, there is need to provide means to extend the useful life of a mattress and to restore performance to pre-use levels.
- The needs of the invention set forth above as well as further and other needs and advantages of the present invention are achieved by the embodiments of the invention described herein below.
- According to one aspect of the present invention, a mattress comfort topper includes a support, a boxtop enclosing the support, and a skirt coupled to the boxtop. In some embodiments of the present invention, the boxtop may include a top, a bottom, a border, an upper binding tape coupling the top to the border, and a lower binding tape coupling the border to the bottom and to the skirt. The top and the bottom may be quilted. A surface of the top may be liquid repellant, and the bottom may be resistant to skidding on the mattress. The border may be substantially rigid and the boxtop substantially rectangular.
- In other embodiments of the present invention, the support may be resiliently deformable and may include a convoluted foam or a contoured foam. In still other embodiments of the present invention, the support may include a viscoelastic foam and/or a latex foam. The viscoelastic foam may include a surface modification technology material.
- In certain embodiments of the present invention, the skirt may be resiliently deformable and may include an elastic material such as spandex. The skirt may be selectively disengagably couplable to the mattress.
- In some embodiments of the present invention, the mattress comfort topper may be selectively disengagably couplable to the border. The top may be completely disengagable from the border or may be partially disengagable from the border. The boxtop mattress coupler may further include a means for selectively disengagably coupling the top to the border, including a zipper having a side coupled to the top and another side coupled to the border.
- For a better understanding of the present invention, together with other and further objects thereof, reference is made to the accompanying drawings and detailed description and its scope will be pointed out in the appended claims.

FIG. 8 is a cross-sectional schematic illustration of a mattress comfort topper according to an embodiment of the present invention including a zipper selectively disengagably coupling the top to the border. - Resiliency, the ability to return to an original shape with removal of a distorting force, is an important property of a mattress, determining to a substantial degree the extent to which the mattress provides comfort to a user. The resiliency of current mattresses has a limited life, determined in part by the extent of mattress use and by the age of the mattress. In a
conventional spring bed 100 where aninner spring mattress 105 is mounted on a box spring support 110 (FIG. 1A ), use of theinner spring mattress 105 over a long period may result in distortion of the supporting springs 115. In aplatform bed 102 where afoam mattress 120 is mounted on aplatform 125 havingslats 130,foam cells 135 may be permanently compressed or the foam embrittled. A user 230 (FIG. 2A ) of the mattress may become aware of these changes after about three to five years. - Some prior attempts to extend the life of the mattress have involved placing a mattress topper on the mattress. To better understand the concepts and advantages of the various embodiments of the present invention, set forth below is a description of an example of a prior
art mattress topper 200 shown inFIG. 2A andFIG. 2B . -
FIG. 2A illustrates the priorart mattress topper 200 placed on the top 118 of aninner spring mattress 105. Thetopper 200 includes a piece offoam 205 coextensive with the top 118 of theinner spring mattress 105, held within afabric enclosure 210, and affixed tocorners 122 of theinner spring mattress 105 orcorners 122 of thebox spring support 110 by straps 215 (FIG. 2B ). - The
mattress topper 200 presented inFIG. 2A andFIG. 2B may have several deficiencies. Themattress topper 200 may not have the same feel to auser 230 as had theinner spring mattress 105 when theinner spring mattress 105 was new. For example, since theedge 220 of themattress topper 200 may not be firm, theedge 220 may not effectively resist compression by theuser 230 moving in his or her sleep or sitting on theedge 220. From an appearance point of view, themattress topper 200 may not have the appearance of aninner spring mattress 105, looking instead like a rather inexpensive solution to a problem. Consequently, the priorart mattress topper 200 may not have restored the underlyinginner spring mattress 105 to its former condition and performance. - Reference is now made to various embodiments of the present invention. These embodiments may return a used mattress, such as a used
inner spring mattress 105 or a usedfoam mattress 120, substantially to the initial performance of the mattress. -
FIG. 3A illustrates an embodiment according to present invention, amattress comfort topper 300, mounted on the top 118 of aninner spring mattress 105 and secured by askirt 315.FIG. 3B illustrates a cross-sectional view of theboxtop topper 300. Aboxtop 310 is coupled to theskirt 315 with a lowerbinding tape 340. Theboxtop 310 comprises a top 320, a bottom 325, and a border orside panel 330. The lowerbinding tape 340 couples theborder 330 and the bottom 325 to theskirt 315. An upperbinding tape 335 couples theborder 330 to the top 320. The combination of the top 320, theborder 330, and the bottom 325 encloses aspace 345. Within the 345 is asupport 305. Thespace 345 and thesupport 305 may be substantially rectangular. Other shapes for thespace 345 and thesupport 305, such as circular, are also possible. - The top 320 and the
border 330 may be quilted, containing at least onelayer 348 between anupper layer 350 and alower layer 355. Theupper layer 350 and thelower layer 355 may be coupled together, as by stitching, at various locations across the top 320 and theborder 330 to form pillows orpockets 360, where theupper layer 350 may be a tick cover layer and thelower layer 355 may be a fabric layer. Thepockets 360 may give stiffness to the top 320 and to theborder 330, tending to maintain the shape of thespace 345 even when a force is applied to the top 320 of themattress comfort topper 300. -
FIG. 4A andFIG. 4B illustrate embodiments of thepocket 360. Thepocket 360 may contain a single fill layer 462 (FIG. 4A ) or several fill layers, for example, filllayers FIG. 4B ), between theupper layer 350 and thelower layer 355. For example, filllayer 462 inFIG. 4A and filllayer 466 inFIG. 4B may be foam layers and filllayer 464 and filllayer 468 inFIG. 4B may be fiber fill layers. -
FIG. 5A illustrates an installation of the upperbinding tape 335 according to an embodiment of the present invention andFIG. 5B illustrates the installation of the lowerbinding tape 340 according to an embodiment of the present invention. The upperbinding tape 335, coupling theborder 330 to the top 320, and the lowerbinding tape 340, coupling theborder 330 to the bottom 325 and to theskirt 315, are installed after thesupport 305 has been placed within thespace 345. - The upper
binding tape 335 may acquire a rounded profile as a result of attachment, giving themattress comfort topper 300 the appearance and finish of amattress 105. The lowerbinding tape 340 may attach theskirt 315 to the bottom 325 and to theborder 330, permitting theskirt 315 to draped so as to encircle themattress 105 upon installation of themattress comfort topper 300 on themattress 105. The form and rigidity of the attached upperbinding tape 335 and of the attached lowerbinding tape 340 contribute to the stiffness of themattress comfort topper 300. - Enclosed within the
boxtop 310 and substantially filling thespace 345 is thesupport 305. For a substantiallyrectangular space 345, thesupport 305 may also be substantially rectangular in shape. Thesupport 305 may be made of a foam that may be a resilient foam, such as a latex foam, or a viscoelastic foam, also known as a memory foam, or a combination of these. - A resilient foam springs back to its original shape upon the withdrawal of a compressive force. A resilient foam may be convoluted, where the foam has a non-planar shape, as, for example, in “egg crate” foams, or contoured, where slits may be cut into the foam. Cutting and/or removing material from a foam blank may provide different amounts of support at different locations on the top 320 of the
mattress comfort topper 300. For example, convoluting may allow hips 235 (FIG. 2A ) to receive more support than a head 238 of theuser 230. - The
support 305 may also be made of memory foam modified by Surface Modification Technology (SMT)™ of Foamex LP (Linwood, Pa.) to provide variation of support across the top 320 of themattress comfort topper 300. Instead of removal of material, different regions of a foam blank receive different amounts of compression, producing different amounts of resiliency.FIG. 6A shows a perspective view of asection 605 of viscoelastic foam processed by SMT, andFIG. 6B shows a top view of asupport 305 where different areas over the top 320 of themattress comfort topper 300 are associated with the different parts of theuser 230, including ahead zone 610, ashoulder zone 615, alumbar zone 620, ahip zone 625, and afoot zone 630. Support of the different areas is adjusted by varying the relative height and area of the raised positions, such as raisedposition 622 in thelumbar zone 620. - The top 320 and the bottom 325 may have additional capabilities to enhance performance of the
mattress comfort topper 300, according to embodiments of the present invention. The bottom 325 may include a skid resistant layer 365 (FIG. 3B ), such as velour, to maintain themattress comfort topper 300 in a centered position relative to themattress 105. The top 320 may include a stain resistant material 370 (FIG. 3B ), such as one subjected to treatment with Nano-Pel™ of Nano-Tex LLC (Emeryville, Calif.), which results in liquids beading up. - The top 320 of the
boxtop 310 may be coupled to theborder 330 by a selectively disengagable means 705, such as a zipper, Velcro™, buttons, or snaps.FIG. 7A showsmattress comfort topper 300 where the top 320 is completely disengagable from theborder 330.FIG. 7B shows an alternative embodiment where the top 320 is partially disengagable from theborder 330.FIG. 8 shows a cross-sectional view of themattress comfort topper 300 further including, as a selectively disengagable coupling means 705, azipper 810 with aninner side 815 attached to the top 320 and anouter side 820 attached to theborder 330. Acover 805 attached to the top 320 conceals thezipper 810 and presents a rounded, finished appearance to theuser 230 when the selectively disengagable coupling means 705 is engaged and theboxtop 310 encloses thesupport 305. - The
mattress comfort topper 300 may be compatible both withinner spring mattresses 105 and withfoam mattresses 120 and may augment performance of a usedinner spring mattress 105 and a usedfoam mattress 120 so as to restore performance to substantially initial levels. As a consequence, useful life of theinner spring mattress 105 and of thefoam mattress 120 may be extended at a cost that may be substantially less than the cost of replacing theinner spring mattress 105 or of replacing thefoam mattress 120. - Although the invention has been described with respect to various embodiments, it should be realized that this invention is also capable of a wide variety of further and other embodiments within the spirit and the scope of the appended claims.
