Cruise in comfort! With our ComfortSeat Lumbar Support System, you can set the amount of lower back muscle support you need for your individual comfort while driving. Hidden under the upholstery of your factory driver or passenger seat, the power lumbar system provides the precise amount of extra lumbar support to your lower back, decreasing strain at your command. With just the touch of a finger, the seat or console-mounted switch activates a pneumatic motor filling the bladder within the seat. Make every drive a comfortable drive.
