Almost as easy as folding and unfolding paper, our Origami Rack converts from a tall six-shelf bookcase to a low, long unit with three shelves - whatever fits your space. You don't need tools. Just a flip. Shelves stay securely in place, giving you room to organize books, store supplies, corral toys or display photos, art and collectibles. Each industrial shelf can hold up to 33 pounds, and the metal frame is as sturdy as it is versatile. It's even easy to move, so your shelving rack can go from room to room or from dorm to apartment when it's time to move.
