A massager for incorporation internally of a seat, and the seat, which may be reclinable, either in a seat portion thereof or a backrest or in both the seat portion and backrest for massaging an occupant seated or reclining on the seat. The massager has a pair of rotatable massage rollers extending longitudinally in opposite directions on a common longitudinal axis and are transported on a self-propelled carriage which travels alternately on two rectilinear paths in the form of parallel tracks. The carriage carries a pivot normal to the longitudinal axis of the massage rollers about which the longitudinal axis is selectively rotated by an electric motor so that the massage rollers are rotated in a circular path for massage different body parts of the seat occupant than when travelling on the rectilinear paths. A switch drum rotated by an electric motor and belt drive carries the carriage on a pair of parallel switch tracks alignable with the linear tracks for switching to alternate travel of the carriage on the rectilinear tracks. A control system of switches activated by the carriage energizes various electric motors in timed relationship for sequencing the travel of the carriage for massaging the hips and/or back of the occupant of the seat.
