ABSTRACT:
The present invention comprises an inflatable air mattress made up of four similar layers of pressurizable cells. The upper two layers are sequentially pressurizable with air pressure from a pressure generator. The lower two layers are under a constant pressure from the pressure generator. Each layer is divided into three square units containing a transversely disposed interdigitated pair of cells, to provide a wave-like motion to any patient on the mattress.
