A shower chair should be easy to use, lightweight, and durable, just like this product: Nova Ortho-med Quick Release Shower Chair. Originally І purchased а shower seat for my mom that was just а bench with side grips built into the seat. The other day she confessed that it did not make her feel secure in the shower. She has problems with RA in both knees and her upper body. It is very difficult for her to stand or walk without good support.
