Replacement Arm Set for Therapeutic Wobble Chair


If your arm set is cracked, broken, or just worn down you can now purchase a replacement set. We sells replacement arm sets to keep your Therapeutic Wobble Chair functioning!

If  you have a wobble chair over 10 years old, we recommend verifying the width of your arm brackets to make sure the new arms will fit, our current wobble chair arms are 2.25 inches wide. If you have an older model chair with arm brackets that will not fit the new arms, you can purchase an assembly kit to update your chair and accommodate our newer arm rests.

The Pettibon System Therapeutic Wobble Chair is a patented solution for back pain relief. With 360° of rotation, side to side, and front to back flexion, you are able to achieve all possible combinations of exercise motion.
