Books appear to defy the laws of gravity when resting on this imaginative and quirky Conceal "L" bookshelf, part of the award-winning Conceal family of floating shelves by Umbra. Attach the shelf to the wall with the included mounting hardware and secure a book onto each end by sandwiching the shelf"s brackets between the books" cover and pages, securing the cover with the built-in clips. Stack additional books next to the end books. The books obscure the bracket from view, creating the optical illusion that they are magically staying on the dramatically sloped shelf. Constructed of sturdy bent wood with steel brackets, the shelf measures 17-inch long by 7-1/4-inch high by 5-inch wide and holds up to 30-pound. Designed by Miron Lior for Umbra - the worldwide leader in innovative, modern, casual and affordable design for the home.
