ABSTRACT:
Waterbed with supplemental support for providing different degrees of localized firmness or support in different areas of a mattress. The bed includes a water-filled mattress having a horizontally extending upper wall and a chamber containing a body of water for buoyantly supporting a person resting on the upper wall, a pocket on the upper wall, and a pad disposed in the pocket and extending across a portion of the upper wall for providing additional localized support for a person resting on the upper wall so that the person is supported by a combination of the water and the pad. The pocket is of greater horizontal extent than the pad, and the pad can be moved to different positions within the pocket to support different portions of the body of a person resting on the mattress. The pad can comprise either an air-filled cushion or a foam cushion, and the firmness or degree of support provided by the pad can be adjusted by adjusting the amount of air in an air-filled cushion or by changing the foam cushion.
