ABSTRACT:
A sleeping mattress consisting of multiple layers of foam material having different densities and structural characteristics with sealed chamber formed therein for receiving a flexible but inelastic liquid filled container. The sealed chamber is located in the torso supporting area of the mattress only. The foam layers supporting and enclosing the sealed chamber are bonded to one another so that the sides of the chamber provide sufficient lateral support to the liquid filled container to provide buoyant support to the torso portion of the body in a recumbent position.
