Abstract: Stepped-edge and side-support members, systems, assemblies, and related methods for an innerspring assembly or other core are disclosed. In one embodiment, an innerspring assembly or core is provided having an interior area of a first height surrounded by one or more exterior, perimeter area(s) of shorter height(s) to provide a stepped-edge innerspring assembly or core. At least a portion of side-support members are placed onto at least a portion of the top surface of the perimeter area to provide edge-support for the innerspring assembly or core. In this manner, a greater portion of the side-support members can be disposed in the sleeping area of the innerspring assembly or core since the underlying perimeter area provides spring support to the side-support members. Further, this support can assist in retention and/or recovery of the shape of the side-support members to further prevent or reduce compression set of the side-support members.

Abstract: Interlocking foam encasement components to form mattress encasements, and related mattress encasements, mattress assemblies, and methods are disclosed. A mattress encasement is formed by two interlocking foam encasement components engaged with each other. Each interlocking foam encasement component includes a foam base member with two foam side-support members provided in parallel or substantially parallel arrangement on opposite sides of the foam base member. To form the mattress encasement, first side-support members of a first interlocking foam encasement component are interlocked orthogonal or substantially orthogonal to second side-support members of a second interlocking foam encasement component to form a foam side-support perimeter for the mattress encasement. The foam side-support perimeter provides an interior area to receive and encase a mattress innerspring or mattress core.

Abstract: Mattress assemblies and methods employing foam side support members and cloth members to enclose mattress cores are disclosed. A mattress may include a mattress assembly enclosing a mattress core. The foam side supports of the mattress assembly may be disposed adjacent to a periphery portion of the mattress core to provide additional support, for example, when a user mounts and dismounts from the mattress. The side support members may be thermally bonded to the cloth members to secure the side supports adjacent the periphery portion of the mattress core. In this manner, the side support members may be precisely positioned relative to the mattress core without the need for adhesives or expensive manufacturing equipment to thermally weld the side support members directly to a foam base.

Abstract: Embodiments disclosed in the detailed description include a unitary or monolithic composite or hybrid cushioning structure(s) and profile(s) comprised of a cellular thermoplastic foam and a thermoset material. The thermoset material may also be provided as cellular foam as well. In one embodiment disclosed herein, the unitary composite cushioning structure is formed from a cellular thermoplastic foam and a thermoset material. The cellular thermoplastic foam provides support characteristics to the unitary composite cushioning structure. The thermoset material provides a resilient structure with cushioning characteristics to the cushioning structure. A stratum is disposed between at least a portion of the cellular thermoplastic foam and at least a portion of the thermoset material to secure the at least a portion of the thermoset material to the at least a portion of the cellular thermoplastic foam to provide a unitary composite cushioning structure.

Abstract: 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.
