After pondering the reviews on this product for awhile I finally based my decision after seeing and hearing a ton of positive things about the chair. Let me tell yah, at first I absolutely hated it, it was uncomfortable but after about 2-3 days of sitting on it the chair kinda molded to my body and I've never felt more comfortable than I do now. Now I can actually keep up with the hours that my stream demands with no back pain which in turn helps me with other things on a daily basis. I will add that I am over the height requirement of this chair, I am 5'10 and am a pretty built guy (200 lbs) yet the chair is perfect size for me, my head doesn't go over the top and there's plenty of room for my legs. The assembly of the chair was cake as all the screws and bolts came pre attached and all the tools necessary came with it. If you're pondering like I once was I suggest to just get it :) It's my favorite piece of furniture that I have ever bought.
