DS-600 was created in 1972 by designers Urs B. Rüegg, Ueli Berger, Eleonore Peduzzi-Riva, and Heinz Ulrich. Their goal was to design a modular seating system that could be adapted to any space and purpose. The result was the DS-600, also known as the “Non-Stop Sofa.” Materials: • Natural wood frame • Filling: high-density foam • Upholstery: eco-leather on a microfiber base
