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?"

Honestly, it was so worth it. So comfy. Love my new chair. Highly recommend.

The sturdy construction of the chair conveys a feeling of stability and durability. The high-quality material and precise workmanship are visible. The adjustable armrests allow me to adjust them to my ideal height, ensuring optimal support for my arms and wrists.
