How can Wayfair even sell this thing? way it mounts to wall (if you can get that far) is UNSAFE ...4 tiny lags with #4 or #6 screws with TINY heads that are supposed to slide into slots on 2 vertical pieces. of course the particle board around the slot is not reinforced so the tiny heads can pull through the particle board and cause the unit to fall off wall. Says shelves will hold 20 or 30 #. I wouldn't trust this unit to support it's own weight. Will be returning unit.
