Took about 2 weeks of evenings and weekends to complete. Wood cost about £120, Audi A6 chair was £100 and the transformer to power the electric adjustment / lumbar support was and old one that I had lying around. Next changes will be a smaller round leather drinks coaster and a bigger screen. The current one is 32" but I want a 42" but will have to wait till someone manufactures one that is good enough for gaming and doesn't ghost.
