I had been looking for a supportive adjustable chair for a while and was overwhelmed by the high prices. This chair was more moderately priced and it has all the adjustments I was looking for. I assembled it myself and it was pretty intuitive. It is comfortable rolls very smoothly feels light but still substantial. Go for it!
I really like this chair. It's comfortable and it leans back a perfect amount for me. However one thing I dislike and the reason I'm giving it 4 stars is that it doesn't go low enough. I'm 5'5" which is not even particular short for a woman but my feet BARELY touch the ground. If I lean back they are several inches off the ground so I have to use yoga blocks as a foot rest. If you're any shorter than 5'5" I would recommend not getting this chair.
