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 an armchair, it's very comfortable. It is possible to sit for several hours. I sit for at least 8 hours a day, and at the end of the day I have no back pain;

I had an issue with my chair, but the team sorted it out under warranty without any hassle. The service was incredibly helpful, friendly, and efficient. You can trust them to take care of you!
