I bought one of these chairs a couple of years ago and it has been great. So when I needed to replace another chair I knew just exactly what I wanted. This is a great chair.
Purchased chair 5 months ago and still can't get comfortable in it. You slide forward when sitting. The adjustable height only goes up so far I'm only 5'4 and I feel I am sitting on the ground when height is adjusted all the way. Wish I could return for something better.
