I am thinking about buying the Razer Enki gaming chair. I've had a shop around and can't really find much for gaming chairs that I like - I like the bucket seat look and prefer to move away from my tatty office chair - and the Enki looks like a good fit.
I'm 188cm (~6ft2), and not sure if it's good for someone over 6ft - my current chair isn't very comfortable because I'm too tall for it - arm rests don't go out wide enough is the biggest annoyance at the moment. I also work from home a decent amount so spend a lot of time in my chair.
