Abstract
A portable cushion containing a vibratory mechanism. The cushion includes a back padding and a front padding and between these paddings is a rigid or semi-rigid frame member which carries the vibratory mechanism. This mechanism is contained in a casing which is located in the lower portion of the frame member. The position of the casing is such that when a cushion is placed next to the back of a chair with its lower end resting on the seat of the chair, the casing will be approximately even with the lumbar region of an adult sitting in the chair.
