Probably the worst thing I've bought on Wayfair. It's basically cardboard and putting it together is both extremely difficult and impossible to avoid some damage due to how flimsy the material is. 

Functionally it's also terrible. You can't have more than a few thin books on each level or it's impossible to get them out. It also pulls away from the wall at the bottom and books slide down the back, so you then have to remove every book, push it back, reload the books.

Honestly it's so awful and so expensive for what you get. I don't understand the good reviews.
