Key is a highly modular storage system that ships flat and assembles easily- the only tool you need is a hammer. The parts are cleverly joined into an exceptionally strong structure by machined aluminum tenon keys. The wood is sustainably harvested, FSC certified maple or walnut plywood, finished with a zero VOC finish. Key is our effort to redefine what sustainable, green, modern furniture can be. Available with optional sliding powder-coated metal doors in a wide variety of colors. Key packaging is 100% paper-based and contains no plastic. The inside of the unit is split in the middle with matching wood and there is a pass-through between the left side and the right-side as well as a hole out of the back. T

he basic short Key module can be stacked up to 5 units high to form tall storage or a bookcase. Stacked Key modules lock together with steel pins so they can't be pushed apart (included). In addition, taller Key stacks can be secured to a wall stud with a galvanized steel anti-tip cable to prevent them from being accidentally knocked over. The full thickness back not only provides a very stiff structure, but also allows Key to be mounted directly to a wall. Stacked Key modules make a perfect modern storage solution for a living room or office.
