Add a Lumbar Support System to your Car, Truck, or SUV Seat for More Comfort While Driving

Cruise in comfort! With the ComfortSeat Lumbar Support System, you can set the amount of lower back muscle support you need for your individual comfort while driving. Tucked away inside the driver or passenger seat, the Lumbar Support System provides the precise amount of extra lumbar support to your lower back, decreasing lumbar 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.

The ComfortSeat Lumbar Support Systems are designed to be universal, however, prior to installing the unit, you'll want to inspect the construction of your seat to determine whether or not you will need a front-mount or rear-mount interior bladder. Front-mount units are installed between the inner foam and outer material of your seat, while rear-mount bladders are used in situations where your seat's exterior material is bonded (glued or stitched) to the supporting inner foam material.
