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?"

The quality of this chair is excellent! It's also, very comfortable. It's worth the price.

Great Chair, not just for looks. I sit at my computer for a few hours at a time with research and work and this is the first chair I have had that I do not find myself adjusting my seating position every 20 minutes. Great construction quality as well. Well worth the cash.
