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.
