ABSTRACT:
Each mattress comprises a plurality of valved cells or cylinders held by a cover in side by side relation. Each cell is made from flexible, essentially inelastic material, and comprises upper and lower cylindrical sections of equal diameter interconnected by one or more corrugated cylindrical sections of smaller diameter. Each lower cylindrical section has an orifice which connects the interior of the cell with an air plenum that extends along the entire underside of the mattress, and which registers with a valve that projects from the inner surface of the plenum opposite the cell orifice. Each orifice may be supported by a small, collapsible section of the cell in a normally open position, so that when a load is applied to the top of the cell it automatically closes the orifice against the registering valve; or, alternatively, the valve may be insertable manually into the orifice to seal it until once again manually removed.
