Well, this desk is only partially assembled due to 1 defective part (metal bar not drilled properly and not countersunk), 1 damaged part (drawer bottom piece cracked) and 1 broken part (ball bearings fell out of the drawer glides).  The packaging was super secure however so I think these are all factory problems. Wayfair customer service was fantastic and replacement parts are on the way.  The instructions say the assembly is an hour but honestly it's more like 2.5 due to the so-so drawings. So far everything does fit together well and no hardware was missing.  I'll up date this review after the replacement parts arrive and the desk is fully assembled.
