Very easily assembled. Very sturdy. I bought it for my 13 yr old son to use at his computer desk for homework and gaming.  He has probably put more miles on it than I have put on my car, yet the chair hasn't once failed.  The wheels are scuff resistant (I guess) because they haven't left a single mark on the hardwood floor in his room.   When I need a new chair for my office, this will be the one.
