A water mattress has a portion of its volume occupied by air or gas filled bodies which lower the total mattress weight and inhibit the under damped natural harmonic motion typical of conventional water mattresses. A method of fabricating the water mattress of the instant invention is also disclosed. The gas filled bodies comprise independent, elongate, parallel chambers having sidewalls which are secured to the bottom panel of the mattress. The chambers are positioned to float between the horizontal midplane of the mattress and its upper surface such that it exhibits the uniform force per area weight distribution characteristic found desirable in such devices. Air is supplied to the chambers through generally aligned access fittings on the chambers and water mattress. The chambers are fabricated of a plurality of staggered, overlapped rectangles of plastic, each having a length substantially equal to the length of the mattress and a width approximately equal to twice the chamber to chamber distance measured along the surface of the chamber structure.
