I used this product after have ankle surgery when I was non-weight bearing for 4 weeks. I had originally tried a much larger and more expensive shower seat that had a backrest, arm rests, and a slider and the chair always felt wobbly and made me feel unsafe. I tried this little guy out and loved it. It is petite enough to fit securely in the shower while allowing me to feel stable and comfortable. For reference, I am 5'5'' and 220 lbs.
