ABSTRACT:
A bed mattress is constructed so that its opposite sides have marginal inclined surfaces which converge to form a relatively shallow truncated rectangular wedge portion on each side of the mattress for self-centering nested engagement in a similarly tapered cavity of a foundation for the mattress. The mattress may be of the innerspring type or may consist of a foam rubber slab. The mattress foundation can be framed and padded or may be formed from rigid foam plastics material.
