I've always wanted a kneeling chair, and the reviews on this one were pretty good. I usually sit for 2-3 hours at a time without getting up. This chair allows for enough adjustability to change things up a bit, and I like that. The down side is that for a 10 to 12 hour work day it's a bit tough on the knees. I LOVE that this chair fits below my desk and I don't have to look at a huge chair bac
