Reversible mattress

Claim 1

A cushion assembly which can be reversed in orientation to expose support cushions having different stiffnesses, said cushion assembly comprising a stiffener member which includes (1) a plurality of section elements which are positioned in generally abutting side by side relationship to one another, each section element defining a first face, an oppositely directed second face, and side edges, each section member also including an abutment ridge which extends away from its second face adjacent each side edge thereof which is abuttable with the side edge of an adjacent section element, and (2) a hinge means connected between the first faces of adjacent section elements so as to flexibly connect said plurality of section elements together; said abutment ridges on said section elements being abuttable to prevent the movement of adjacent section elements such that their second faces pivot towards one another, and said hinge means connected between said section elements allowing adjacent section elements to move such that their first faces pivot toward one another, a first support cushion connected to said hinge means, said first support cushion having a unitary structure and a predetermined stiffness, and a second support cushion connected to the second faces of said plurality of section elements, said second support cushion having a unitary structure and a predetermined stiffness, the predetermined stiffness of said second support cushion being greater than the predetermined stiffness of said first support cushion.
