<p>A mattress consists of a foam body (2) having recesses (8) at positions corresponding to the locations of protruding portions of a patient lying on the mattress. Foam blocks (14, 16) can be selectively placed in portions of the recesses (8). An encasement member (4) encases the foam body (2) and includes a top foam sheet (18). A bloused waterproof, non-shearing, flame retardant and antibacterial top sheet (24) forms a portion of the encasement member (4) covering the foam sheet (18). A zipper (26) in the encasement member (4) enhances air circulation into and out of the mattress.</p> |
