One of the worst things I ordered on Wayfair, this piece is literally falling apart as you put it together. Not only the 3d printed details that you’re supposed to hammer in simply don’t fit - which in its turn destroying the wood outside, but also the wood is destroyed from you simply screwing screws in. Instructions have some steps not in order, so make sure you attach all the pieces to the shelves before attaching them to the walls. You either have to be extremely careful when putting this piece together (and hopefully the 3d details that you’ll receive would be correct size) either don’t waste your time and buy normal shoe rack. 
P.S. This shoe rack is so small my boyfriends sneakers of size 12 are barely fitting in
