William by Zanotta is a three-seater straight sofa designed by Damian Williamson, defined by a refined balance of minimal form, generous comfort, and precise tailoring. Introduced in 2010, the collection has become a sophisticated living-area staple, with clean upholstered volumes, slim aluminum alloy feet, and a composed silhouette that feels both contemporary and enduring. Built with a steel frame, elastic strip suspension, and removable fabric or leather upholstery, William is designed for a relaxed yet highly polished seating experience. Goose down cushions add softness and depth, while the modular William family can be complemented with solid wood shelves in oak, grey-stained ash, or natural Canaletto walnut on selected configurations, bringing additional function and material warmth to refined residential or hospitality interiors.
