Abstract
A mattress includes reduced-firmness materials along a central region thereof in order to mitigate the occurrence of a central ridge following repeated use of the mattress as a sleeping surface. An associated box spring may also, or instead, present a central region with reduced firmness. An adjustable member may be employed to controllably compensate for the development of a central ridge.
