Not great for standing on
I bought this for physical therapy exercises because I couldn't bring myself to pay $10 for shipping for the one my PT recommended (NOT from Amazon). This is not particularly firm - certainly it is not nearly as firm as the one I use in the office for balance exercises. I use it rounded side down and step on the flat side. My feet sink into it and the ends pop up somewhat. It's okay, but after trying to make it work for a few weeks, I've decided to buy the one my PT recommended in the first place. I will keep this one only because I'm sure my children will love to use it as a balance beam.
