An air-filled mattress with virtually no air loss has a plurality of air-filled bags grouped into zones of uniform air pressure. A controller monitors the air pressure in each zone and activates a blower to adjust the pressure in any zone in which the measured pressure differs from the desired pressure by more than a threshold amount. The blower is otherwise deactivated. The bags are deflated by reversing the direction of flow from the bags to the blower. The bags are fastened to a mattress base using an attachment fitting that receives an elongated bead on the bag's bottom edge into a chamber along the mattress base fitting. The mattress base can be attached to any of a variety of different conventional bed frames. Tabs fastened to the mattress base having a hinge and a hand malleable aluminum plate can be bent to grasp a variety of different bed frames. A unique air manifold between the blower and the bags, a unique hose coupling between the blower and the manifold and a unique air coupling between the manifold and the bags are also described. The controller is incorporated into an independent housing with an adjustable handle, wheels and a movable keyboard and is operated according to a four-mode control program.
