Not a problem to assemble definitely have someone with you when you put the back on though. That part is tricky. I enjoy coming into my office to see that chair everyday. No joke.
The only thing I would change is I would like adjustable arms. It was easy to put together and is really comfortable. The chair fits in with my decor. The delivery was very quick. I ordered one day around 2:00 PM and it was delivered around 10:00 the next morning. I can recommend to anyone who Has back problems as I do.
