It's a nice, sturdy bookcase and a good size. However, as others have mentioned, the backing is very flimsy. The product I received did not have the backing cut in an exact rectangle to fit the bookcase like it should have been, so nailing it on was a challenge and it doesn't fit properly. 

I'm not sure if it's because of the backing or my skills with bookcase building, but it leans slightly to the right. I do like how it looks though, and if I anchored it to the wall it would probably stand straight.
