I would give these 4 stars except for the fact that they smell like smoke!  

My husband put them together while I was gone or I would have had FedEx come back and pick up the boxes. 

They look nice and, yes, the backing is flimsy but that’s normal for inexpensive bookshelves. We bought three and they look really nice side-by-side.

Its a bummer, I just wish Wayfair/Closetmaid would have warned us that these obviously came from an area or warehouse with smoke damage. Now I’m trying to decide if I want to go through the hassle of disassembling and returning them and shopping for replacements.
