Beings I'm a 73 year old widow and noone to really help with things I was surprised how easy it was to put the chair together.  It did take me about 45 minutes only because I didn't have a third arm; otherwise, I could have gotten it together in less than 30.  It's a comfortable chair and rolls nicely.  I like that the arm rests fold up so you can get closer to the desk if need be.
