is there ever damage to the chair being used with back joy?
The back of the back joy seems hard and not completely smooth. I haven't used mine yet because it seems as though it could make marks on a wood chair or some fabrics. Is there a way to protect the chair and still receive all the benefits of using the back joy? For example, I thought of putting a towel between the chair and the back joy. I'm not sure if either the towel or the back joy would stay in place. I am concerned even more about possibly injuring my back by not sitting on the back joy properly because of trying to protect the chair!
