This desk is made of a poor quality pressboard, not much better than dense cardboard.  Screws strip and split the material very easily.  

The plastic drawer alignment tabs (factory installed) were misaligned.  I had to pry and unscrew them to make the drawer work.  

Missing 4 self-tapping screws from the sealed parts pack, too.

Wayfair, you can do a lot better than this.
