The chair was very easy to assemble until I got to attaching the back the holes were pretty hard to line up. The chair is very comfortable my only complaint is that the locking mechanism does not lock it in place completely. I would recommend this chair.
Pros: The chair is a little bigger than expected. So extra roomy is good for some people! I have less back aches at the end of the day which was my goal when I purchased this chair. It is comfortable. Cons: I've had it just under 2 months and one arm padding has come loose (not repairable) and it has the awfullest squeak at all times whether you are in it and move or move it while not sitting in it.
