An improved therapeutic chair is provided which advantageously massages the muscles of the back of a user in a number of directions while conforming to the curvature of the user's back, thereby greatly enhancing the therapeutic value of the chair. Preferably, the back support of the chair includes a plurality of spaced-apart massaging devices located adjacent the back of a user when the user is seated in the chair. Each massaging device includes a plurality of elongated rollers interconnected in a radial, outwardly extending fan-like fashion about an elongated shaft. The rollers are pivotally mounted and forwardly biased such that, in use, the rollers exert a slight pressure on the musculature of the back while the pivotal mounting allows the rollers to conform to the curvature of the back. An electrical motor powers the massaging device thereby rotating the shaft and roller arrangement to provide the massaging action. In particularly preferred forms, the massaging devices are reciprocated up and down within the chair while the fan-like roller arrangement revolves thereby imparting a variable massaging action to the musculature of the back.
