I like this one. This book shelve is designed for people who have little space to store their books. Since my library is full, I took notice. All my shelves are stocked and I have no space for more cabinets. This Italian designer seems to know the problem, so he designed the Sapien Bookcase.
This bookcase enables you to store your books horizontally. This ‘thing’ can accommodate up to 70 books. The shelves are removable, so you can play around with it. If it’s full, you do not see the shelves anymore. This makes it a nice book case / shelf in my opinion.
