Berlin designer Jannis Hülsen has developed a fascinating new upholstery technique, using bacteria to grow a cellulose skin over the surface of a wooden stool. Called “Xylinum” after the bacterium used to create it, the furniture is immersed in a tank while the bacteria consumes sugar and builds a cellulose fibre structure. Once finished it can be dried out to form a material that’s 100% biodegradable. In Hülsen’s words: Xylinum is a research project that asks: “What could future materials and production processes look like?” For a comprehensive look into the Xylinum project, check out the full article by Dezeen.
