This was originally delivered to me missing one box of 3. After contacting Wayfair, I expected to receive the missing box, however the whole unit was reshipped.  I have no use for the extra parts so they ended up in the trash, which felt very wasteful. 

The assembly was not too difficult. The most tedious part was using the tiny screwdriver on the screw to hold in glass. I do appreciate the firm boards that make up the backing. Many units use a stained cardboard. These are thicker piece that slid into place. 

Despite the problems with shipping this unit looks very nice and seems much more sturdy than any unit I've previously used.
