The stool is better than I hoped except..there is a disclaimer that came with the stool that says the castors provided were for use on carpet and another set is available for use on hard surfaces! So I have to catch the stool while it moves around trying to evade my butt. I'm getting pretty good at it.
I was worried the price of the chair would mean cheap quality. This is such a great chair. I love it and sit on it for most of the day in my in home office. I highly recommend!!!
