Walter Knoll: CIRCLE Design: UNStudio/Ben van Berkel. "Circle was inspired by the design of the Mercedes-Benz Museum in Stuttgart, Germany. It is made up of four parts, two or more of its parts making up a semicircle or other configurations. The slope of the back and the seating area make up an unbroken flow from sitting upright to lying in relaxation. The height is the one thing that remains constant. The connection of convex and concave shapes results in sweeping sculptures."
