The Optic’s two supporting frames perfectly slide to create a light system of staggered shelves: the shelves are wider in the middle to accommodate large objects, while the side shelves are lighter and cantilevered. The frame comes in 2 types of metals with a total of 9 different finishes. The shifted frames give the bookcase a striking 3D effect and permit different configurations in the space: side by side on the wall, overlapping or in the centre of the room, joined with an “L” arrangement as a partition within the room.
