This chair is a god send I am 6' 1" and I am a skinny Indian 14 year old that sit at his computer all day. Now I am a power user once I sit down I stay for at least an hour and I have managed to pull 8 hours in my other chair. The only two issues that I see is that the bottom mesh is not the best for comfort and that the headrest digs into my neck. To solve the bottom mesh you could get a mattress topper and shove it in the gap and for the headrest just don't attach it. One of issues that I couldn't solve is that the arm rests are hard to move up and down and they stick. I do believe they use a standard mount so it might be possible to get a pair from Secret Labs for $60 and all you have to do is add some washers and a new hold or two. That is why I gave it a 4 star review. I feel that you paying a premium and not getting what you should.
This chair is so comfortable that I was sitting in it at home after work as done. The lumbar and head support adjustments make the biggest differences to choose this over the other chairs at Staples. Glad I took my time and went with this one.
I would definitely recommend this chair! I've had it for almost two weeks now and I love it. I was originally thinking about going for something more expensive but I'm glad I didn't because this one has what I was looking for. It has helped me improve my posture a bit and makes sitting in front of my computer for hours a little more bearable. I also like that you can lock the backrest at different angles when you recline it which makes it comfortable for TV watching since I don't have a couch yet. It was doable to assemble by myself. If you're able to try it out in-store first like I did I would recommend doing it to make sure it's the right fit because everyone is different.
