This Wagan Tech 12-Volt Deluxe Velour Heated Seat Cushion is a better looking, better functioning, more ergonomic, more durable and overall better seat cushion than the venerable original It features a copper nickel alloy wire wound over a fiberglass core with a high temperature silicone sheath encapsulating it. This new element is more efficient and delivers an even heat transfer throughout the entire seat cushion. Being wound over a fiberglass core allows it to be more flexible and less prone to wear and tear. The cushion also features a larger, patented pressure pad in the seat area that allows for different individual seating styles. The 3-position switch Hi Off Low allows you to adjust the heating level to your desired setting and includes a LED power indicator. The seat cushion’s straps include metal cinch hooks on the bottom and 1 adjustable strap on the back for a custom fit to any chair. The rear strap is now easily opened to accommodate those seats that have seat belts built in. Not only is this a heated car cushion, you can use it at home or in the office when you use the optional 12 volt to AC adapter sold separately.
