The 405 Duc armchair was designed in 1976 by Mario Bellini for Cassina and is a distinctive example of Italian 1970s design. The chair features a modular panel construction, held together by subtle zipper closures running along the sides, giving the design a clear architectural and graphic quality. Upholstered in original high-quality black leather, the armchair offers a soft, supple feel and a comfortable seating experience thanks to its generously padded cushions. The clean lines and bold structure create a balanced combination of comfort and character. The chair is in very good vintage condition and reflects Bellini’s innovative approach to furniture design.
