The seat shells are embedded in a frame construction. Makes a stable impression. The backrest can be adjusted perfectly using the lever. No problem finding a good sitting position.

12/05/2016 and now 04/04/2016 the chair has been retired, never broke never had any issues, these GEN 1 dxracers were good but the cushions are flat and the fabrics are beyond stained... beer mostly, milk, food, sweat, boogies and people and friends on it. I believe that to be 7+ years out of a chair i think those years were worth the $300 spent. R.I.P. DXRACER.

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!
