ABSTRACT:
A flexible, water bed pad support system for reclining chairs and the like. The water bed pad is attached to the chair and comprises a plurality of integrally connected, plastic cells containing water or a similar material such as a water mix solution. An orifice such as bleed valves and/or narrow pipe orifices are provided at the junction or connection areas between adjacent cells, and the bleed valves enable water movement between adjacent cells in response to variations in pressure changes when a person shifts on the chair. These pressure change responses result in the water bed pad to slowly conform to the body curvature of a person, and equalize the support under the chair.
