The seat shells are embedded in a frame construction. Makes a stable impression. The backrest can be adjusted perfectly using the lever. No problem finding a good sitting position.

I went with DXRacer chairs because of their reputation for great customer support and the comfort of the chair. When an issue came up that wasn’t covered by the warranty, they quickly responded and helped me out, which just reinforced why I chose them in the first place.

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?"
