I've had this chair for about a month. It's perfect for my needs. Excellent support.

The adjustment options are perfectly adequate. The backrest can be tilted backward by 135° so that you can watch a movie on the PC and lean back comfortably. The height adjustability of the chair itself and the armrests is also fine. I would therefore give it a clear recommendation for anyone who likes to sit in front of their PC for long periods.

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!
