ABSTRACT:
The combination of a pressure-switch operated vibrating motor, enclosed within a cushioning material, such as synthetic or natural foam, having an enlarged surface area relative to that of the motor. As a person applies pressure on said enlarged cushioning means, as by leaning on the cushion, the pressure switch is engaged to close a circuit thereby starting the vibrating motor enclosed within the cushioning means. The cushioning means acts as a damping means for the vibrating motor for greater comfort than would otherwise occur if the vibrating motor were not so enclosed.
