If you have a tendency to pile up books near your bed or couch (I do) – you will love this bookcase. Designed by studio Reverso for furniture brand Cattelan Italia, the piece takes this piling habit and turns it into a visually pleasing object. DNA Bookcase lets you arrange your books into a double spiral, imitating a DNA cell diagram. Filled with books, the shelving itself becomes invisible, making the whole arrangement look like a book sculpture. Lovely idea, wishlisted.
