I just got this today. Putting it together was a snap, and the instructions were clear and included the only tool you need. However, it's not so comfortable as I hoped. I was looking for an adjustable lumbar support. I like that the chair has one that adjusts both up and down and back and forth. But the actual support is very thinly cushioned and poorly shaped. Also, the armrests have a shape which only works if your arm is straight ahead. When you are typing, your arms are angled toward the center and thus rest across the ridges and not in the nice comfortable groove. It seems that the designer did not understand the positions of the human body, which is the defining character of ergonomics. So, while this seems to be a solid, well made chair, it has some design flaws which make it not a comfortable place to sit, which is the whole purpose of a chair!
