ABSTRACT:
The water-filled chair or couch of the present invention includes a frame, and a bladder positioned on the frame. The bladder has a seat portion, a back portion, and a channel extending substantially across the width of the bladder so as to provide communication between the seat and back portions. The bladder is partially filled with water and is void of air such that, as a person sits down into the chair, water is forced substantially instantaneously from the seat portion through the channel and upwardly into the back portion of the bladder which expands to provide support to the person's lower back. The channel has a depth substantially less than that of the seat or back portions. A restrictor bar extends across the channel to maintain the shape thereof as water passes therethrough. A dam is provided at least on the front edge of the bladder to provide support thereto. A heating element and vibrator are provided for additional comfort.
