The Cassina Met 250 sofa, designed by Piero Lissoni, exemplifies minimalist design with clean, geometric lines and a modular structure. The new upholstery in Höpke's VIVO 601 fabric ensures durability, easy cleaning, and exceptional seating comfort. The slender metal legs lend the sofa a sense of lightness and elegance.
