I have been using this chair daily for over two months now, often for long hours. Here is my impressions. I love the shape of this chair. It fits me (I'm 6'1", 200 lbs). This is the best chair I have ever owned and used! Now I can lean back and take a nap!

A simple direction made the chair assembly easy. I finished within 20 minutes.

I like the chair, however, having a separate cushion for the lumbar support doesn't really work well. It fell over every time I got up. There should be lumbar support built into the back of the chair. I also had to add an ergonomic seat cushion because the seat was very hard. This solved the issue of the lumbar support falling down when I got up because I tucked it behind the seat cushion to hold it in place, but the lumbar support at that low height resting directly on the chair is way too low for a proper lumbar support. It would be well worth paying more for a chair with the lumbar support in the chair and a much softer seat cushion. I like the way the rest of the chair functions, such as the arm rests and way the sides of the chair wrap around.
