ABSTRACT:
A foundation assembly is disclosed in which a wire grid is supported above a support frame by a plurality of wire form members extending parallel to one another and arranged in pairs. The wire form members have leg portions extending therefrom and are rotatably mounted to the wire grid to enable a wire subassembly to be shipped with the wire form members rotated to folded positions in which the leg portions lie against the wire grid. After shipping, the wire form members are rotated to extend the leg portions away from the wire grid at an angle less than ninety degrees where the paired wire support members cooperate together forming a rigid structure to prevent collapse of the foundation assembly.
