Good for increasing balance by standing. Builds stronger legs.

I use this at work. I don’t use a standard office chair, I use a stool on wheels. This helps me build my core strength by sitting it on the seat.

There is only one thing I don't care for and that is strictly on me. I have sensitive feet and the little knobs on the top are a bit uncomfortable - so I wear socks and that helps. This stability disk is definitely superior to others I have tried. Upon arrival it will need a little more inflation, so don't forget to order an inflation device if you don't have one.

This is similar to an item I used in physical therapy to regain flexibility in my foot. I bought it to use at home - it's very helpful.

Good price. I'm 212 and it holds the pressure. Grand kids like to play with it.
