Abstract
A foundation unit which can be collapsed for compact shipping and which later can be elevated to a fully expanded state. The foundation unit includes a rectangular, grid wire top bearing structure, a rigid bottom substructure, and a series of spaced, parallel rows of support members extending between the top bearing structure and the bottom substructure. The support members are hingedly secured to the top bearing structure and the bottom substructure to permit reduction of the foundation unit to the collapsed state with the elements of the rows of support members lying essential prone. In the elevated state, each of the rows of support members is composed at least in part of a plurality of spring wire segments comprising a pair of generally flat support elements forming a generally V-shaped configuration.
