20100175197 | PERIMETER STIFFENING SYSTEM FOR A FOAM MATTRESS - A stiffening system for the perimeter edges of a foam core mattress comprising a coil spring (or other spring-based) structure disposed along one or more perimeter edges (e.g., one or both side edges, the foot, the head, or a combinations thereof including the foot and both side edges) of a mattress having a foam sleeping area. The perimeter spring structure is rectangular or square in cross-section and provides sufficient stiffness for comfortable seating on the edges of the mattress and is joined to the foam core by planar fabric elements that span the joint between them and are attached to both. The sleep area provides the softness and other salutary effects of a foam sleeping surface while the stiffer spring perimeter element provides the rigidity need for comfortable seating and wear resistance. | 07-15-2010 |
20120167312 | MATTRESS SIDE/EDGE SUPPORT SYSTEM - By providing a plurality of preformed components which are quickly and easily affixed in engagement with each other, a final construction is realized which peripherally surrounds any desired mattress configuration in cooperating association therewith. In this way, a new foam plastic product is achieved which is capable of being quickly and easily mounted to mattress constructions peripherally surrounding the mattress and providing an enhanced side support system. In this way, any desired mattress size or configuration is capable of being peripherally surrounded with a foam support assembly for enhancing the mattress construction and configuration. Furthermore, by employing the present invention, a rapid, convenient, and virtually labor free assembly is realized. | 07-05-2012 |
20130025068 | MATTRESS AND SIDE RAIL ASSEMBLY WITH HIGH AIRFLOW - A side rail assembly for supporting an edge of a mattress includes a layer of a polyurethane foam comprising an open cellular structure, wherein the open cellular structure comprises about 10 to about 40 cells per inch, a hardness of about 35 pounds-force to about 100 pounds-force, and a density of about 1.2 pounds per cubic foot to about 2.0 pounds per cubic foot, wherein the layer is configured to be disposed about a perimeter of an inner core of the mattress and is configured to permit the flow of fluid from and to the inner core through the layer. | 01-31-2013 |
20130081209 | CELLULAR MATTRESS ASSEMBLIES AND RELATED METHODS - Embodiments disclosed herein include cellular mattress assemblies and related methods. The cellular mattresses assemblies may comprise thermoplastic material and/or thermoset material to achieve appropriate comfort and support characteristics. The cellular mattress assemblies may also comprise one or more components including a cellular thermoplastic foam profile to achieve appropriate comfort and support characteristics. The cellular mattress may include a support layer, a comfort layer, and a transition layer between the support layer and the comfort layer. | 04-04-2013 |
20130167302 | CUSHIONING ELEMENTS COMPRISING BUCKLING WALLS - Cushioning elements having a first plurality of parallel buckling walls and a second plurality of parallel buckling walls each comprising an elastomeric material. At least some of the buckling walls of the second plurality intersect and interconnect with at least some of the buckling walls of the first plurality. The elastomeric material comprises an elastomeric polymer and a plasticizer, and a ratio of a weight of the plasticizer to a weight of the elastomeric polymer is from about 0.1 to about 2.2. A height of the cushioning element is at least about 5 inches (12.7 cm). A mattress includes a core structure including buckling walls and a flexible material formed over the core structure. | 07-04-2013 |
20130167303 | MATTRESS WITH A SPACER TEXTILE - A mattress has a frame, which is formed from an elastic material and laterally delimits an interior. Arranged in the interior are at least two elastic spacer textiles, which are each releasable from the frame and from one another. The mattress has a high degree of reclining comfort and, because of the modular construction, can be cleaned in a conventional washing machine. | 07-04-2013 |
20130291312 | FOAM MATTRESS OR CUSHION WITH SUPPORTING EDGES - A foam support, such as a mattress or cushion, with additional edge supports. The edge supports may be in the form of a support member that may include firmer foam than the body of the mattress. The support member may include a top portion and a bottom portion. The top portion of the support member may have a larger surface area than the bottom portion of the support member. | 11-07-2013 |
