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 chair is the most convenient and comfortable one I've ever used.

I've bought two DXRacer chairs now, and both times the shipping was insanely fast—my first one showed up in a day, and the second only took two. These are by far the most comfortable gaming chairs I've had, and they keep getting better with more color and design options. Plus, I really like the lumbar support pillow that came with it.
