An inflatable mattress comprises superposed lower, middle, and upper sheet layers. The lower and middle sheet layers are joined to each other in a manner to define an inflatable air chamber. The middle and upper sheet layers are secured to each other in a manner to define at least two independently inflatable mattress portions. Fluid passageways provide fluid communication between the air chamber and the inflatable mattress portions. A plurality of ventilation apertures are through the upper sheet layer for ventilating air from the inflatable mattress portions. The sheet layers are arranged such that air introduced into the inflatable air chamber flows through the fluid passageways into the inflatable mattress portions and then out through the ventilation apertures.
