Patent ID: 7178187

Claim:
An asymmetric innerspring having a plurality of interconnected asymmetric wire form coil springs, each of the coil springs having a generally helical coil body with a plurality of turns with at least two of the turns having a unique pitch or radius, a support end contiguous with one end of the coil body, and a base end contiguous with an opposite end of the coil body, the support ends of the coil springs being arranged in a plane to define a single support side to the asymmetric innerspring, wherein there is a greater density of wire in an upper half of the innerspring than in a lower half of the innerspring, wherein the largest pitch angles of the coil springs are proximate to the base ends of the coil springs, and wherein the smallest pitch angles of the coil springs are proximate to the support ends of the coil springs, and wherein the coil springs are interconnected at the support ends.
