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?"

It was a successful gift. I love it.

As a someone who spends extended periods at a computer, I sought a premium chair that would focus comfort, support, and function, while simultaneously allowing me to play guitar from the same piece of furniture. This chair exceeded my expectations in every aspect. The chair's adjustability options are impressive. The height can be easily adjusted, as can the pitch of the backrest. The armrests are also adjustable.
