The adjustment options are perfectly adequate. The backrest can be tilted backward by 135° so that you can watch a movie on the PC and lean back comfortably. The height adjustability of the chair itself and the armrests is also fine. I would therefore give it a clear recommendation for anyone who likes to sit in front of their PC for long periods.

This was for my son's birthday. I was hesitant to buy such an expensive chair but after sitting in it, it is worth the money.!! I'm thinking of getting one for myself!

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?"
