Cheers guys. The chair is an FX Automotive Detroit . It's the all black, with red stiching. Very comfy, I got it purely for the lumbar support, and have spent upwards of 15 16 hours if not more sat in it without a single problem. I've got a habit of reclining the back a touch ( it reclines flat ), and lowering the pedestal, and putting my feet on the desk edge so I'm almost lying down to game. One of the most comfortable postions ever.
The top bracket is just a cheep £5 tilt one from Ebay.
