The Superonda Sofa (1967) by Archizoom Associati is an icon of Italian radical design, produced by Poltronova. Made from two interlocking polyurethane waves coated in glossy PVC, it was the first sofa without a traditional frame, allowing multiple configurations as a bed, chaise, or seating. Its playful, sculptural form rejects modernist rigidity, embodying the pop and postmodern spirit of the 1960s. Today, it remains a collectible statement piece that bridges art and furniture design.
