Description
- This application claims priority of U.S. provisional application No. 61/428,979 filed on Dec. 31, 2011 and is incorporated by reference.
- 1. Field of the Invention
- The present invention relates to mattresses, mattress toppers, mats and sleep systems. More particularly, it relates to systems that can be used to provide comfort and support. It also relates to a system that can be used to provide supplemental support to compensate for mattress sag.
- 2. Prior Art
- Generally, there have been a variety of systems proposed for use to help in enhancing comfort and to support parts of the body. Devices of this type include mattress toppers positioned over the mattress as well as other devices positioned between a mattress and a box spring. The existing devices may be configured to elevate one part of a person's body or to provide different levels of support in different zones.
- Different people have different body types and it often the case that the comfort enhancing sleep device that works best for one person's body is not the best device for a different person.
- Additionally, existing mattresses often develop mattress sag or an indent after several years of use. Such a sag or indent may make the mattress uncomfortable or even unusable. Replacing the mattress with a new mattress is very expensive. Positioning a rolled up towel or pillow below the mattress may cure the sag, but it is rare for the towel or pillow to provide the optimum amount of adjustment.
- In view of the above referenced deficiencies in the prior art, it is an object of the invention to provide a sleep system which can be in the form of a mat, a mattress topper or a mattress that provides an adjustment to conform to a user and may cure the defect of mattress sag.
- The invention is directed to sleep systems comprising multiple foam members having different densities. The foam members may be releasably or permanently attached to one another.
- The invention further includes at least one air filled bladder. A first bladder placed within the system provides added comfort and support. A second bladder may be placed in another position, such as approximately under the knees of a user, to provide additional comfort and support. A third bladder may be placed to provide support for the head. Additionally, the system, or a portion thereof, may be placed on an existing mattress to compensate for mattress sag.
- The foregoing aspects and other features of the present invention are explained in the following description, taken in connection with the accompanying drawings, wherein:
-
FIG. 1 is a perspective view of a sleep system in accordance with a first preferred embodiment of the invention, where the removable cover is revealed at the top; -
FIG. 2 is a plan view of the sleep system in accordance with the first preferred embodiment of the invention; -
FIG. 3 is a cross-section view thereof, taken along line 3-3 ofFIG. 1 ; -
FIG. 4 is a second cross-section view of and the sleep system in accordance with the first preferred embodiment of the invention, showing the bladders in an inflated state; and -
FIG. 5 is a cross section view of a mattress topper system designed to compensate for a sagging mattress in accordance with a second preferred embodiment of the invention. - Referring to
FIGS. 1 through 4 , there is shown anassembly 10, which may be, for example, a mat, a mattress or a mattress topper placed on top of a support S. Theassembly 10 includes ahead member 14, abody member 16 and abase member 18. All of themembers members 14 a, 16 a and 18 a which correspond to the first three members. The additional three members are positioned opposite the first three members and may be employed to provide varying support levels for the opposite sides of the bed. (Where only thefoam members corresponding members 14 a, 16 a and 18 a.) Thus, two people having different body profiles may share a single assembly having foam densities specifically selected for their respective body profiles. - The
foam members base foam member 18 being greater than the density of thehead member 14 and thebody member 16. In the case of a standard weight, the densities are 4, 6 and 10 lbs per cubic foot, respectively. Preferably, each has a thickness of two inches in the case of a mattress topper, or thicker in the case of a mattress. - In alternative embodiments, polyurethane foam is used in place of latex foam and varying densities of either foam may be used are used in place of the preferred densities.
- As best illustrated in
FIG. 3 , thehead member 14 andbody member 16 are positioned above thebase member 18, which extends the entire length of the assembly. Thehead member 14 is relatively smaller than thebody member 16 because thehead member 14 is positioned to support the head and shoulders of a user, where thebody member 16 is positioned to support the body and legs of the user. In order to allow the user's shoulders to sink deeper into the assembly, thehead member 14 is constructed of lower density foam. - The
head member 14, thebody member 16 and thebase member 18 are adhered to one another by an adherent, preferably a glue adherent. Alternatively, themembers members - An air inflatable bladder 22 is positioned between the
base member 18 andbody member 16 approximately centered along the height of theassembly 10. Asecond bladder 24 is positioned between thebase member 18 and thehead member 14. Athird bladder 26 is positioned between thebase member 18 and thebody member 16 at thebottom end 20 of theassembly 10. In the preferred embodiment, corresponding fourth, fifth and sixth bladders (22 a, 24 a and 26 a respectively) are positioned between the support S and thefoam members 14 a and 16 a. (Where only thebladders - The
bladders vessels having valve 29 for receiving and releasing air. While only onevalve 29 is shown, it is preferable for eachbladder own valve 29. Thebladders - The adhesive used to secure the
foam members bladders foam members bladders bladders bladders bladders FIG. 4 ), thebladders foam members bladders foam members bladders foam members - The
bladders FIG. 2 , may be of rectangular, circular, oval and other shapes, as may be appropriate for providing comfort and support. - The
assembly 10 offoam members bladders removable cover 28. Thecover 28 encases the member or bladder in the manner of a tightly fitting pillow or quilt cover, having a zipper or other closing apparatus. Thecover 28 may be removed and washed separately, as required from time to time.Cover 28 is preferably constructed of Lyocell (commonly known as Tencel®). Openings may be provided incover 28 for thevalve 29 that provides air to thebladders - While the
assembly 10 has been described with emphasis on a mattress topper on a mattress, it will be understood that implementation is also possible in a mattress or a mat. - Referring to
FIG. 5 , there is provided a second preferred embodiment of the present invention in form amattress topper 30. The purpose of themattress topper 30 is to compensate for sag or indent in a mattress M. Themattress topper 30 may be constructed in a conventional manner, as for example, of a single piece of foam with a suitable outer covering, or in accordance with the principles described above. A lower surface 32 of the outer covering may be configured with a hook and loop fastener system, as described above. Abladder 34, of the type described above, is placed betweenmattress topper 30 and mattress M. An outer surface ofbladder 34 is configured with a hook and loop fastener system so thatbladder 34 may be releasably fastened to the bottom surface 32 of the outer covering ofmattress topper 30 at a selected position. The position is chosen so thatbladder 34, when inflated, compensates for any sag in mattress M, in regions where mattress M has a surface that is not flat (i.e. that sags due to extended use). It will be understood that for a larger amount of sag, a greater degree of inflation ofbladder 34 is used, while a lesser amount of air and a smaller degree of inflation may be used to compensate for a smaller amount of sag in the mattress M. - In certain cases, the
bladder 34 alone, with the use of suitable releasable fasteners to keep it in place, can be effective when at least one bladder is placed between an existing mattress topper and a mattress to compensate for mattress sag. In particular, a bladder also can be used between a mattress and a box spring. - The mattress assembly of the present invention has been described with reference to a bed, but the assembly is also applicable to lounge chairs, beach chairs, traditional chairs, etc. When incorporated into a chair or similar support structure, the assembly is positioned above the support structure similarly to how the
assembly 10 is positioned above the flat support surface S described herein. - It should be understood that the foregoing description is only illustrative of the invention.
