Abstract
A modular air mattress including three separate pieces, one to support the head region, the middle abdomen region, and the lower leg region of a human body, respectively. The mattress pieces include a low air loss ventilating air mattress piece and conventional, non-ventilating mattress pieces. The ventilating mattress piece is positioned to support a body region susceptible to bed sores, while the conventional mattress pieces are positioned to support non-bed-sore susceptible body regions. Each piece has means for releasably coupling to each of the other pieces so that the ventilating air mattress piece and conventional mattress pieces may be conveniently positioned, and securely coupled, in any longitudinal series. The releasable coupling means also facilitates easy and convenient replacement and/or rearrangement of the mattress pieces.
