Originally designed in 1976 by acclaimed architect and designer Mario Bellini, the Duc-Duc Sofa for Cassina is an iconic expression of bold lines, innovative structure, and timeless style — now renewed with sustainable materials and improved comfort.

This updated version stays true to Bellini’s pioneering vision while evolving for modern living. Its distinctive panel structure — uniquely assembled with a full-length zipper — creates a clean, architectural silhouette that’s instantly recognizable.

Inside, advanced cushioning technology uses polyurethane foam wrapped in 100% recycled PET fiber, responsibly sourced mainly from ocean plastics — a result of Cassina LAB, the brand’s sustainability-driven research program in collaboration with Poli.design at Milan Polytechnic.

The minimalist design has been refined by removing the original side cushions, creating a sleeker profile without sacrificing the signature elegance and generous comfort. Optional armrest cushions are available for additional personalization.

Available in a two- or three-seater version, the Duc-Duc Sofa brings sophisticated Italian craftsmanship, environmental responsibility, and Bellini’s timeless design into any contemporary living space.
