Grant Sofa
The Bonaldo Grant modular sofa by Massimo Castagna is shaped by broad, uninterrupted curves.
Semicircular and semi-arched modules combine with chaise lounges, peninsulas and ottomans to form open seating arrangements, including compositions for the center of a room. Fabric or leather upholstery rests above a recessed metal sled base that lets the curved upholstered volumes define the design.
Every detail, considered.
