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?"

I had been looking for some months and seen this beauty.

Very comfortable and sturdy chair! It was pretty straightforward to put together, instructions were easy to understand. Got this for my home office for work, and I can sit for long periods of time without needing to shift or get up due to soreness. Would highly recommend for gaming and work!
