I purchased this for my mom who has limited mobility due to arthritis. She has arthritis in her hands, legs and feet. She is able to work the hand brakes with no problem. She is 5'1" and the medium was perfect, only making a minor adjustment with the hand rail. My mom sometimes travels with me and is unable to walk far and we have to search for a place for her to sit and rest. This will allow her to walk a little further and we will not need to look for a place to sit. I wish it was possible to just fold the legs up. My mom loves this. She has already talked about where she will take it ... one store in particular that only has one motorized wheelchair for the entire store.
