These shelves are great and well made. We ordered two. They come with the option to mount to the wall so that you do not have to worry about them falling. Each shelf holds a good amount of weight. It is a sleek contemporary addition to the office area. 

Con: The only thing I would warn is that the black finish did rub off on to the wall when we were adjusting where to place this she shelf. It did not easily come off. This isn't enough to take away a star.
