Abstract
A box spring assembly having modular spring elements distributed in an array beneath rectangular pockets of a wire grid top. The elements include a single piece of wire formed into a head configured to support and be contained within selected pockets of the wire grid top, a base formed of the two ends of the wire to attach to a lower base frame, and a pair of compressible arms formed into a pattern of bars and bends which give firm elastic support with economy of wire.
