ABSTRACT:
The present invention entails a seat structure including a water bladder that serves to support an individual disposed on the seat structure. In particular, the seat structure is contoured so as to form a well cavity intermediately between a leg support area and an inclined back. Formed in the well cavity is a displaceable water well. When an occupant sits on the water well the water therein is displaced upwardly along the inclined back and provides a padding and support structure about the back of the individual occupying the seat.
