An exercise and rehabilitation chair includes a framework having lower frame members, pivotal front legs, and elongate rear legs. The chair includes a seat assembly having a seat bottom and seat back and upper arms, each upper arm being pivotally coupled at one end to a generally upstanding support arm and at an opposed end to a front leg. Bearing housings pivotally connect corresponding support arms and rear legs and establish a fulcrum about which the seat assembly may rotate. The bearing housings may be slidably positioned longitudinally along corresponding support arms and rear legs using pin fasteners or, alternatively, using motorized gear assemblies. The displacement of the fulcrum relative to a user's hips is adjustable for regulating the resistance of chair operation. A foot assembly is pivotally coupled to the front legs. All pivotal connections correspond anatomically to a user's joints for low joint stress and low-resistance exercise.

An exercise and rehabilitation chair and method includes pivotal front support legs, rigid rear legs, a seat assembly having a seat bottom and seat back and upper and lower arms, each upper and lower arm being pivotally coupled at a rearward end to a pivotal support arm rigid with a seat back and at a forward end to an upper end of a pivotal front leg. Bearing structures pivotally connect corresponding support arms and rear legs and establish a fulcrum about which the seat assembly may rotate. The bearing structures are simultaneously adjustable longitudinally along the pivotal support arms and rigid rear legs with displacement of the fulcrum relative to a user's hips regulating the resistance of chair operation. A foot assembly is pivotally coupled to the front legs and the forward ends of the upper and lower arms. All pivotal connections correspond anatomically to a user's joints for low joint stress and low-resistance exercise.
