Abstract

A nestably stackable pre-assembly for a box spring foundation having a top support surface formed by a substantially rectangular border wire, lateral surface support wires and longitudinal surface support wires. The top support surface is supported by a series of longitudinal formed wire structural support members having V-shaped sections extending down from the top support surface. The structural support members are attached to the surface support wires by clips. The V-sections of adjacent structural support members are angled towards each other in pairs such that they form a series of four-sided open-apex pyramids. The pre-assemblies can be stored and shipped by attaching a first pre-assembly to a bottom wooden frame, and stacking additional pre-assemblies on top of the first.
