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.

Overall quality is good & it is packed well w/good instructions, arrived via FEDEX quickly. As a 6'3", 260lb, man who spends close to 12 hours at his computer (between work and live streaming) I have to say this is pretty comfortable.

In my experience, this is the finest seat available. This chair is ideal for those who have to sit for long periods.
