ABSTRACT:
A box spring comprises a rectangular base frame, a wire grid, and a plurality of parallel rows of coil springs supporting the grid atop the base frame. Each row of coil springs is made from a single continuous length of wire in which adjacent coils are interconnected by an interconnecting segment of the wire. Each interconnecting segment is in the form of a generally diagonally extending bar having substantially parallel end portions interconnected at the center by an offset section, which offset section is formed by rotating the offset section relative to the parallel end portions while the end portions are restrained against rotation.
