The new Lumbar Support is an adjustable support for those who require additional lower back support due to back pain, or just to maintain proper posture. Easily installed on any of our EZ Rider seats, including our Rotating Seats; installation instructions are provided. This unique design offers vertical adjustments using the large dial, so you can focus your support where needed, the smaller "star" shaped dial pushes the lumbar pad outward into the seat back, just crank it until the pad has provided preferred support - these adjustments can be done while seated. Check out the Lumbar Support at your local dealer, or online!
