<p>A mattress box spring comprising a plurality of substantially conical coil springs rigidly fastened at the spring ends of lesser diameter to a support frame such that the spring end coils of greater diameter lie in a substantially common plane, a wire mesh overlying the end coils in the common plane with the spring end coils being unattached or free-floating with respect to the mesh and with respect to each other, and a cloth cover or pad disposed over the mesh and having a periphery attached to the frame to hold the assembly together. Preferably, the diameter of each spring end coil lying in the common plane is greater than the corresponding spring height.</p> |
