Stringent but invitingly open is how Normann Copenhagen describes Sum, its lightly scaled modular sofa available in easily accessible preconfigured edits. Simon Legald's seating beckons with its spread-out armrests and generous contours while slim, angled aluminum legs airily lift it from the floor. Available in 2-, 3- and 4-seater versions, the sofa has a harmonious look front and back so it can stand in the middle of a room. With custom upholstery in a fine textile or leather, the modules are made of soft molded PU foam with a steel frame and topped with lush foam cushioning.
