The ergonomic are nice with plenty of lumbar support. The parts and materials of the chair feel strong and durable. I feel confident in the longetivty of this chair so far.

Took no more than 15 minutes to put it together. I have been using it for months and found no problems.

As someone who spends a lot of time sitting and designing, I can't recommend this company enough to anyone looking for a new chair. My old cheap chair was wrecking my back, even when I tried to maintain good posture. I ended up sitting in awkward positions just to feel comfortable. I never realized how much a firmer chair could make a difference. A friend recommended this brand, and after using my chair for over a year now, I can't imagine going back.
