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's so humanized, like, you can adjust it in all these different positions to find your perfect comfort zone. As a gamer and YouTube enthusiast, I like the comfortable chair. It's worth to buy.

I tried out alot of chairs before this purchase, never really found a chair I was COMPLETELY comfortable and happy with. This chair is very well made, appearance 10/10 real good looking chair. You will not be disappointed at all!
