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 was an excellent purchase. I tried out many different chairs at the store but this is definitely the best one I could find. I work from home now and I’m glad I invested on a great office chair.
