When I had hip surgery at a young age, it was impossible to take a shower comfortably. This seat was my best friend for about a month and a half and I still use it! I couldn't stand long periods of time and this is a convenient way to shower without actually sitting on the ground. I can see why many elderly people would use this and I am thankful it was so light and easy to move. No instillations needed and you can easily use it as needed. Great device and very secure. You'll never need to worry about it slipping!
