I had no issues with assembly. All parts were in box (extra screws/bolts also included). Directions were simple to follow. All parts fit as required. Although included, I did use my own tools for assembly. As a reminder, and stated in directions, do not use drill to tighten screws/bolts as you will depress metal frame - hand tighten only. Desk looks very good assembled. I state this because I read that quiet a few had issues with parts fitting - thankfully I did not. Very nice little desk that works perfectly for my wife's needs (painting, various arts & crafts, and laptop). Only caution is when using the lift for desk top be careful not to pinch your fingers when lowering - easily done.
