I bought this for a friend...he loves it. i wish i had known about it a year ago after heart surgery. I had so much pain trying to get up from a chair.
I bought large but it ran a bit big but still functions okay. A little stiff so if your going to be their a while it makes a ring on your skin. After it wears in a while it's okay. For me 5'9" 198 lbs .
