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?"

Great chair. I’m 6’1 300 pounds so I’m a pretty large guy. This chair has held up easily with no issues. This one has been a great investment so far.

Very easy to assemble, sturdy and comfortable. I had a DXracer chair before (forgot the model) and they do last pretty long. But the price is a little steep on this model and I am not sure if I would recommend this one
