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.
This is a great product added to my daughters dance workout ! She uses this to strengthen her core and help with a strong balance. Our daughters ballet teacher recommended this and we are very satisfied with the results.
