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 provides excellent comfort and support without breaking the bank, making it a fantastic choice for a wide range of people. I believe this chair will serve me well for decades to come.

I am thoroughly pleased with my purchase in every aspect. The product I acquired is of exceptional quality, exhibiting versatility and reliability, thereby significantly improving my overall user experience. I would wholeheartedly recommend it to individuals seeking such qualities in a product.
