ABSTRACT:
This imvention is a chair comprising a seat and a backrest wherein the backrest is pivotable back and forth relative to a floor surface, the backrest being comprised of: a backrest frame extending above the seat, a massage frame mounted by the backrest frame and adapted to reciprocally-slide longitudinally of the backrest frame, massage rollers mounted by the massage frame and positioned so as to protrude beyond the backrest frame into the space occupied by a sitter's back, and a cover on the backrest frame covering the massage frame in front of the massage rollers whereby the cover will be interposed between a sitter's back and the massage rollers; and an actuating device mounted to the massage frame and being so constructed and arranged whereby pivoting movement of the backrest will effect relative movement between the massage frame and the backrest frame, thereby causing the massage rollers to move longitudinally of the backrest frame in a reciprocative manner as the backrest pivots back and forth.
