I purchased this item because I have Fibromyalgia and cannot stand for long periods. I used it the first time and it seemed to work until I try to fold it again and had to have my son do it for me and he had a hard time folding it as well. The third time I used the product I noticed that the legs were getting wider and I was getting lower, yeap it gave way right from under me. The product claims it holds up to 300 pounds NOT TRUE, I'm only 170 and it buckled. DO NOT BUY. I'm returning mine.
