This furniture can hold itself together. A San Francisco-based designer named Robby Cuthbert has created architectural furniture made from wood and steel cables. The rows of cables in his chairs, lamps, and tables are placed precisely to maintain stability and strength through tension alone, similar to a suspension bridge. The pieces don't use adhesives or fasteners to stay together, and the result is truly furniture-meets-sculpture. Cuthbert says he studied architecture in college, and he explains on his site that laser cutters and 3D printers are key to his work. You can see more of his furniture at his website, and they're available to purchase on Etsy.
