This new invention is a frame and servo assembly for attaching to massage chair seats manufactured without an existing servo assembly. It includes a frame body, on which there is sliding rack, a screw drive, a positioning stabilizer bar, and a connecting plate. The sliding rack is coupled to various motor brackets, the screw drive, a driving block, a screw drive stop block, and a plurality of wave shaped massaging wheels.
