Only available from Hammacher Schlemmer, this is the cordless portable massager that lets travelers relax with a back massage during a long flight or car ride. Controlled with a simple integrated button, the fabric-swaddled device delivers five types of vibration massage that vary in speed and intensity to help prevent stiffness and maintain blood flow. The massager straps to a seat back and has no dangling wires or bulky components; with automatic shutoff function. After treatment, the 1-lb. massager rolls into a lightweight bundle that is easily carried. Requires three AA batteries. Spot clean. 24 1/2" L x 19" H x 1" D.
