Abstract: The invention provides a nestable box spring foundation having a generally rectangular perimeter divided into a plurality of rectangular openings by a grid of longitudinally and laterally extending wires. Support is provided by a pair of generally U-shaped wire members mounted at their ends to adjacent grid wires. The members are of simple configuration and accordingly inexpensive to manufacture, simple to attach such as by welding and by virtue of their symmetry provide good lateral strength.

Abstract: A unitary base member for supporting a wire spring assembly of a bed foundation. The base member includes a lattice formed of a plurality of lateral members and a plurality of longitudinal members. The lattice has a lower surface and an upper surface for mounting a wire spring assembly thereon. The lateral members are oriented substantially parallel to each other, and the longitudinal members are oriented substantially parallel to each other. The plurality of lateral members are positioned above said plurality of longitudinal members. Significantly, the lateral and longitudinal members of the lattice are integrally and inseparably formed together with each other as a single piece of substantially rigid plastic for preventing movement of the members with respect to each other.

Abstract: A new Unitary Body Bedding Foundation for constructing the top deck portion, the end walls and the side walls are all as a single piece. The inventive device includes a top deck member having two spaced apart side walls and two spaced apart end walls on its bottom face. The side walls and the end walls may designed to be detachable from the top deck member. To aid in supporting the top deck member, the unitary body bed foundation may also include a support frame member adjacent the bottom face of the top deck member. The support frame member can be either a lattice support frame member having a plurality of longitudinal and latitudinal intersecting ribs included on the bottom face, or at least one lateral slat extended transversely between the two side walls and the ends of each lateral slat being accepted by a slat brace on each of the side walls.
