Be advised that there is not much padding on this chair. However, I have sat for an hour or two and found it reasonably comfortable. The backrest helps quite a bit. 

It has a small profile and doesn’t get in the way in close spaces. The rollers are adequate but I may consider swapping out some quieter ones. 

Assembly was easy and all the parts were included. I’ve used it for a couple of months and it has held up well.
