Mechanical massaging device incorporated in the back rest of a seat or other supporting equipment that has a pair of cross shafts operatively mounting paired rolling massaging wheels that can be selectively positioned and rotated to produce massaging through suspension fabric on the body of a person supported thereon. The massaging device has three centralized input shafts extending longitudinally within the confines of a cavity in the back rest or other support which are selectively driven by user controlled motors remote from the massaging wheels. The lateral spacing of the massaging wheels as well as their rotation can be adjusted. The massaging wheels can be selectively positioned at an infinitely number of vertical positions within the cavity to provide massaging action for enhancing the supply of blood to supported body areas under pressure of body weight. The device includes a mechanism for varying massage pressure and the massaging wheels and associated components can be moved to an out of way position when inactivated. A thigh massaging unit in a seat is also disclosed.
