I had a narrow empty space on a living room wall that I wanted to be able to put books in, but there was a heating vent below so I couldn't put a freestanding bookcase. This fit perfectly and discreetly on the wall and now my books are all together.  It's not for anything too heavy nor is the space between the shelves too high - so I wasn't able to put up certain picture frames.  But if you have small items or books, this is an efficient item.  I might get another for my son's room - to put next to the bed in place of a nightstand.
