My bad knee and had back limit my ability to kneel down and do home repairs close to The floor! I've put off several repairs due to my physical limitations. Since I got this chair, I've done three repairs and one lower cabinet organising. This chair has spared my back knee from some severe pains. You don't have to be a car mechanic to find this chair useful to you. The chair is light and rollers are sturdy and help to make moving while sitting, a very easy task.
