Designed by Vico Magistretti, this bookcase with its simple, clean-cut lines was the outcome of a detailed analysis of the classic model featuring side supports and shelves. The diagonal bracing struts become the support structure, and house the shelves, eliminating the need for side supports. Putting the focus on the hinges and the six shelves, the structure, which can be folded away, can also be used as a room-divider.
