Overall very nice
February 12, 2013
I like this chair a lot, but I have two issues with it. First, the lumbar support doesn't stay in place. It's basically just a cheap piece of plastic that slides up and down and I find it slips down after a few hours of sitting. Second, the seat is suspended on a set of wires. You sit on a pad that's on top of those wires. Maybe it's the way I sit or the shape of me, but I find that after a long period of sitting I can feel the pressure of one or two of those wires quite distinctly. Finally, the tension on the seat back isn't adjustable in the way I'd like. It's very light, and although you can set locking positions to prevent it from going back to far, I would find a bit more tension with a full range of motion to be better.

Great chair
July 25, 2011
I really like this chair because the back is so flexible and the arms are adjustable in height, width apart, and angle. I personally like it better than the Aeron.

Good chair for the money
February 20, 2011
Now that I've had this chair for a while I think I can say I'm very impressed with it. When I'm at home I'm almost ALWAYS sitting at my desk, and unlike cheap chairs from big office stores, this chair has never made my butt, back or arms hurt. I'm glad I got the lumbar support because without it I don't know if there would be enough support to keep me from slouching. The first 2 tension settings always provide enough support, but I'm pretty thin. One thing I was worried about when ordering was whether the arm rests would be soft enough since other chairs tend to hurt my bony elbows, but the rubber is plenty soft. The only complaint I have is that after a few months of heavy sitting the seat lost some of it's spring and cushion, but it's still very comfortable. This chair is about as cheap as you'll find for real ergonomic chairs, but the build quality has been great so far and it meets all my requirements for comfort without paying for even more expensive chairs. I'm 6'3" and about 150lbs, and always had problems with cheap office store chairs, so if you're like me this chair is definitely worth the investment.
