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?"

Took me about 20 minutes to put it together alone. Super comfortable and so far solid.

This chair is much better for me for everything I do than other brands like Respawn and other competitor brands. I was able to sit in the respawn chair for very little time before experiencing pain in my bum bum. However, with this chair. I am able to sit for more than 5 hours at a time to stream, work, and game. This chairs reclining feature is also very robust and very stable. The arm rests can also be adjusted in a bunch of ways that can make it comfortable for almost anyone.
