ABSTRACT:
A therapeutic chair is provided having angularly displaceable seat bottom and seat back positioned on a supporting base for pivotable movement relative thereto. The seat bottom and seat back include longitudinally extending sidewalls having inwardly facing surfaces which may be selectively displaced inwardly to effectively provide support for the occupant of the chair. Selective displacement of the inner sidewall surfaces is achieved through incorporation of selectively inflatable air cells which are restrained against the respective side walls. These cells are inflated to expand inwardly and provide the proper size adjustment and support of the occupant in maintaining the desired body position for comfort and avoidance of the involuntary extensor thrust positioning.
