The Cooling / Heating Automobile Seat Cushion

This is the padded seat cushion that employs thermoelectric technology to cool or heat water circulating through its seat and back, providing quick relief from sun-baked auto seats and comfort during long commutes. A quiet, compact 30-watt pump/power unit circulates water that's up to 40º F cooler than the ambient temperature through soft rubber tubes embedded in the cushion to draw heat away from your body as you sit; it alternates from cooling to heating at the flip of a switch. The cushion uses no Freon or other materials harmful to the environment and its 1"-thick foam padding protects the circulation tubes against punctures and leaks. It consumes about as much electricity as a compact fluorescent bulb, so it can be left on for short periods when the vehicle isn't running. The cushion has soft cotton fabric that resists stains, and spills pose no threat because there are no electrical components within; four adjustable straps secure it to most vehicle seats. The power unit plugs into a 12-volt outlet and sits unobtrusively on the floor; an AC adapter is included for use at home, office, or on a patio. The cushion measures 44" L x 20" W; the power unit is 6" H x 3" W x 2" D. (6 lbs.)
