This simple and clever shelving system by Mehtap Obuz of Demirden Design for Ilio is modular and can perform several tasks. Comprised of light wooden components, Katkat can be stacked as high or as low as you want. And because there are two sets of connecting holes in each segment, you can adjust the height of the shelves – perfect for oversized books of magazines. And if you need extra seating, each unit can serve as a stool. The item is light, intuitive in assembly and visually stimulating. The piece can be made from oak, walnut and/or african padouk, which is another beautiful variable – you can mix and match layers of different colors.
