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?"

I must say, the inclusion of head and lumbar pillows has truly enhanced the overall comfort of this space. If you're on the hunt for a reliable and affordable chair, look no further. I've got just the recommendation for you.

This chair is solid and super comfortable. I highly recommend it. Assembly was easy with very clear, precise instructions.
