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 quality is excellent. The leather is of high quality, and the product includes additional support and metal frames. This surpasses any chair at my workplace.

This chair is suitable for my requirements and provides a high level of comfort. I am satisfied with the purchase. The chair I bought has surpassed my first expectations.
