Abstract

A mattress includes at least in part a center convoluted foamed latex layer having opposite ends and opposite sides, a substantially flat lower surface and an opposite convoluted upper surface with the convoluted surface including a plurality of upwardly directed peaks and upwardly opening valleys. An upper layer of polymeric/copolymeric material spans the convoluted upper surface with a lower surface of the upper layer being substantially contiguous to the peaks and substantially closing the valleys. A frame of polymeric/copolymeric material substantially peripherally surrounds the convoluted layer and has an upper surface in underlying bonded relationship to the upper layer upper surface. A plurality of randomly sized pieces of foamed latex are housed within and substantially fill the valleys thereby progressively resisting compression of the peaks under the influence of different weights of persons supported upon the upper layer while imparting softness comparable to mattresses constructed entirely of solid unconvoluted foamed latex.
