This Cave Bookcase solves the common problem of having a bookshelf yet having no place to sit in your apartment to read the books it holds. It provides a comfy-looking seat built right into the middle of the shelf, complete with overhead light. It's certainly neat looking, but it seems to me that a space-saving design like this would be perfect for people who live in tiny apartments, and people in tiny apartments can't afford to drop $10,700 on a bookcase.
