A driven massager of roller type for incorporation into a seat or backrest of a chair or into a mat as traveling massage unit. A traveling housing of the massage unit houses and carries drive and operating mechanisms for driving the traveling unit and operating a rotatable pair of elongate massage pressure rollers carried thereon disposed axially spaced in a common plane above the housing and driven alternatively in circular clockwise and counterclockwise motion while the traveling housing is stationary along a rectilinear path of travel or traveling thereon in two opposite directions on a pair of parallel gear racks laterally spaced defining the path of travel. The traveling housing is provided with driven paired gears on opposite sides for traveling on the gear racks. The massage pressure rollers are mounted on a support that provides for moving the rollers between two planes spaced above the level of the traveling housing for variably applying massage pressure to a user seated in the chair or reclining thereon or on a mat. The various circular motions and movements between the planes can be effected simultaneously or separately with the massage unit stationary or traveling.
