I purchased this chair about 18 months ago. For the first year it was great! Recently however the cushioning on the seat has completely worn out and rendered the chair very uncomfortable for long periods of sitting. I'd recommend spending a little extra on a quality product!
I first tried this chair in the store and liked it better than anything else they had on the floor. Ordered one and had it sent to my office. The most difficult part of the assembly was getting the arm rests on the screw holes and a little embedded into the fabric and stuffing of the cushion but once it was threaded it was pretty easy to finish it. I've been using this chair now for about 4 months. Still as comfortable as the first day that I got it. I work 9 hour days and I needed something that wouldn't be unbearable to sit in for that long everyday. If something ever goes wrong with this chair I would buy this chair again.
My son uses it for gaming. It is much more comfortable than other popular brands. When assembling the arms make certain you do not tighten them all the way until you have both holes lined up.
