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.
I am very petite, so this chairs fits me well, but I'm certain it would not work for someone over 5'10" or so. I use it for my art work and it helps me balance and keep my back from straining. Love it.
