Abstract

A one-sided mattress construction includes a spring assembly with asymmetric spring coils. Only the bottom portion of each spring coil is attached, either to adjacent spring coils or to a bottom surface of the mattress. The top portion of each spring may have a narrowing taper that permits the top to move independent of other adjacent springs.
