This circular bookshelf designed by Zhdanova Irina is not only stylish and innovative but makes worries of books falling off the ends of shelves a thing of the past. Not only that but the spherical design also enables you to use it not only as a bookshelf but an exercise tool too, much like a human hamster wheel! Finally because you can turn the shelf round, the issue of not being able to reach the books on the top shelf becomes irrelevant.
