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 chair itself is decently comfortable, and I was initially satisfied. The chair itself is for my son who is 6'1" and he loves how the chair fits him. The headrest and curves in the back of the chair are built for someone his height. The armrests also adjust which is a bonus.

For me, this chair is perfect. I've never felt so comfortable sitting in front of a computer before. All I can say is that this chair is a really good value for money, so I can definitely recommend it. top!
