I love the chair. I thought the headrest would be great but it sits too low so my shoulders rest against it which is annoying. You can adjust the angle but not the height so I removed it. Other than that it sits nice so far. Had it for a couple of weeks now.
Great chair! I am a photographer so I can spend a lot of time at my computer editing photos for easily 4-6 hour stretches. Before getting this chair I was experiencing a lot of back pain. The adjustable lumbar support doesn't have a very wide range but it's enough to help. It was easy to put together and the mesh is nice and cool for the Arizona weather. The only small complaint I would have is that after a lot of time sitting in it with shorts the mesh starts to push into your legs and makes that webbing pattern. I don't mind the pattern look of the pattern (since I'm at home) but it IS the tiniest bit irritating on the skin. If I had known this I MIGHT have considered getting one of the other chairs that has a mesh back to keep cool but a fabric/padded seat. I have a feeling I will appreciate the mesh once our summer hits and it gets 110-120 degrees here in Yuma - so perhaps not. Otherwise still very much a 5 star worthy chair.
I use this chair while sewing and like the way I can sit up straight and support my back. I did take off the headrest because it was not at the proper angle for me. The chair is very adjustable and comfortable. I would highly recommend it!
