The desk arrived in great time but the assembly instructions were terrible as no pieces were labeled leaving you in a trial by error construction. Tiny screws have to be perfectly lined up with holes or you spend enormous amounts of time trying to line everything up. Got it together in several hours and had each piece been labeled I am sure I could have done it in 30 to 40 minutes. Wayfair made this one as hard as possible, it has made me rethink my future purchases!
