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?"

Some people may think the armrests are too short, but for me, the highest height is more than enough for me to play games. The lumbar cushion strikes a balance between softness and firmness, and it remains fixed in position even when you change your posture.

A pretty good chair. The materials feel high quality and solid. Easy to put together.
