An inflatable mattress construction having use as a maternity mattress. The mattress is provided with a central, generally cylindrical cavity which extends through the thickness of the mattress. The lower end of the cavity is enclosed by a bottom panel, while a top panel is located within the cavity and the peripheral edge of the top panel is sealed to the upper surface of the mattress bordering the cavity. The central portion of the top panel is secured to the bottom panel. A gas, such as air, can be supplied to the chamber between the panels to thereby inflate the upper panel and adjust the depth of the cavity to accomodate the abdomen of a pregnant woman.
