ABSTRACT:
A box spring 10 for supporting a load includes a horizontally extending frame 12 which defines a load supporting area, a plurality of formed wire springs 14 mounted on the frame 12 for providing symmetrical resilient support under the load, and a grid 16 spaced above and in parallel relationship with the frame 12. Each spring 14 is defined by an integral wire having a horizontally extending section 32 with first and second ends 34, 36 and a fishmouth section 54, 56 associated with each end. Each fishmouth section 54, 56 includes a V-shaped portion with a torsion bar 58, 68. The V-shaped portion of the fishmouth section 54 adjacent the first end 34 of the horizontally extending section 32 faces oppositely from the V-shaped portion of the fishmouth section 56 adjacent the second end 36. Spacer segments 41, 47 are located on opposing sides of the horizontal section 32 to provide stability to the spring 14 under load.
