This book shelf is called Reader's Nest and it is designed by David Design in 2009. This bookshelf is made out of painted metal, is simple but ingenious and perfect for all book lovers. This is also very great because if you put a book on top of the shelf it works as a book marker, and you can easily find back to the page where you stopped reading. I think this is really beautiful, simple but yet special, and a great way to decorate your home with your books. If you fill up the hole shelf, it'll look like you've hung books straight on your wall.
