Two months ago I finally bought this chair and have to say: "I'm impressed." It's the BEST chair I've ever sat on. Even my back pain has improved or (almost) disappeared.

Really nice quality chair for the money. It's very comfortable, easy to put together, and well-designed. This feels better than the office chair that I spent double the price on.

I have an older model (~8 years) and one of the wheelbase arms broke off. DXRacer was responsive to my email question and told me which base would work with my model. If you're looking for parts, the links can be found in the FAQ question: "If my chair's warranty has expired and I need to purchase corresponding parts, what should I do?"
