(Posting this just after I assembled it) 
I needed a black basic chair for my desk at my apartment to get work done, this did the job. 
PROS 
* I got the one with the arm rest: the arm rests are detachable and adjustable in terms of height
* the height of the chair is adjustable and works well
* I was able to assemble this easily and without any tools (if you have tools the most you would need would be a screwdriver)
CONS:
* the material does feel cheap, slightly less polished than what I'm used to but it gets the job done. I just got it so I don't know how robust or durable it is with time... if I remember I may upload an update :)
