The "920" armchair was designed by Afra and Tobia Scarpa in the mid-1960s (circa 1966) for Figli di Amedeo Cassina in Meda, during the same design period as the "Bastiano" system. Conceived as a single element of a modular series—the same unit that, bolted together in sequence, composes the 920 sofas—it condenses the Scarpas' rationalist approach into a compact cubic volume: the construction is exposed, not hidden, with the frame serving as an expressive element. This piece is upholstered in cognac leather with visible stitching, framed by a solid ash band that runs along the base and rises to crown the armrests—a lighter alternative to the more common walnut version. The seat rests on elastic straps stretched over a gray lacquered frame, with covered polyurethane cushions and the model's characteristic gray block feet. The seat cushion retains the original Cassina label (“B/5”, Made in Italy), an uncommon survival that documents its authenticity.
