This trooper of a chair has been carrying the weight of my fat arse (which is getting fatter as the years go on) for 6 years on my home kit. I bought this throne as I had damaged nerves in my neck and my cheap starter throne was exacerbating this problem.
Well, as well as reversing my back and neck pain, playing drums actually became therapeutic for it when I ordered this chair. I sit down, play, and the back rest cushions my lumbers and after a 20-30 minute session (with stretches before hand) my back feels like I've just completed Yoga! Amazing!
A slight drawback is lack of adjustability of the rest on the throne, wish it could come a tiny bit more forward, but that's only a minor complaint. Also it is quite heavy so it doesn't really suit to be transporting to gigs in your mums hatchback, other than that I'm very happy with the 9608MB!
