The felt construction of the woven panels ensures that the seat warmer will not break down or tear apart with use. Extensive occupant testing has demonstrated the safety, flexibility and strength of these heated car cushions.


Adjustable Lumbar Support

If you suffer lower back pain while driving, our fully adjustable lumbar support system may provide relief. Made from heavy-duty polypropylene, these inflatable support pads are easy to use and much more durable than standard rubber bladders.
