From side tables, benches and sideboards to space-filling shelf units, the elements of the YU system offer a wide range of furniture solutions that can be assembled, converted and expanded without tools. The YU Compartment of color-coated metal or blued steel takes center stage. Just insert it into the grooved wooden YU Boards in the desired direction and the furniture can grow layer by layer. Despite the huge variety, all YU configurations are connected by an almost iconic character, since the interaction of the projecting wood boards with the colored compartments create a distinctive shape. A sliding door and tray are complementary.
