Very comfortable chair that will fix your core and lower back issues. Purchased one, tried it for a few weeks at home and I'm buying the 2nd one for my office. I saw it first in one of my coworker's place and she loved it. Inflate it to your preferred comfort level and enjoy being sitting down in the most healthy way. The only thing I'd like to see would be the availability of other different colors.
Bought this to help with balance, obviously. It does take a bit of work to master balancing on this board, but that's not the board's fault! Good size to get both feet on nicely.
