Abstract
Disclosed is a one-piece inflated air mattress that can be used as such or laid over a hospital bed mattress. Its body is formed of a series of transverse parallel pillow-like air tunnels connected at their ends with a pair of lengthwise distribution channels. The body has an inlet end, to which an air pressure source is connected, and a terminal end; the distribution channels running between the two ends and tapering from one end to the other, being wider at the inlet end than at the terminal end. An open-ended plenum conduit, located at the inlet end of the body, communicates at its ends respectively with said distribution channels.
