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.

An inflatable air mattress formed from a one piece elongated body having an air inlet end and a terminal end comprising: a substantially planar lower portion having a longitudinal air distribution channel along each longitudinal side; an upper portion comprising a plurality of straight elongated pillow-like air tunnels; said air tunnels disposed transverse of said body adjacent to and parallel with each other; said air tunnels being sealed from said lower portion along substantially all their length; each of said air tunnels having an opening at each end thereof to be in fluid communication with said distribution channels; each of said air tunnels being integrally formed with a small air pocket at each end, each said pocket extending over and covering the adjacent distribution channel, thereby to increase the width of the mattress; an open transverse plenum conduit at an inlet end of said body, said conduit opening into said distribution channels, where by said channels, said air tunnels and said plenum conduit communicates with each other; and air pressure source means operatively connected to said transverse plenum conduit for supplying said conduit, said channels and said tunnels with pressurized inflation air.
