Sectional sofas


Antonio Citterio

The Adda sofa features a clean, contemporary style. Its lightweight structure and generously filled goose-down cushions feature piping that highlights their soft, welcoming shapes. The Adda sofa rests on a metal base covered in leather or fabric, while the exposed cast-aluminum feet reveal their graceful, yet absolutely modern, vibe. The comfortably soft armrest and backrest cushions slip over the base using a simple and effective bayonet coupling system. The cushions are creased with a unique lengthwise stitching detail that produces a slight wrinkle in the surface of the upholstery – that can be crafted in fabric or leather – and that, in addition to following the natural fold created when seated, lends a distinctive look to the sofa.
