Bonaldo Grant Modular Sofa Designed by Massimo Castagna

The Grant Bonaldo modular sofa, designed by Massimo Castagna, develops through a fluid composition of continuous curves and soft volumes, designed for large and dynamic environments. The collection includes semi-circular modules, semi-arc elements, chaise longues, peninsulas and ottomans, which can be freely combined to give rise to different configurations, adaptable to residential and contract contexts.

The absence of edges and interruptions in the design emphasizes a formal continuity that encourages conviviality, naturally orienting the seating toward a more open and dialogic dimension. This setting makes the system particularly suitable for placement in the center of the room, where its configuration helps to define areas of relationship within lounges, salons or hospitality spaces.

The sofa is available in textile upholstery or leather, while the frame rests on a backed metal sled base, a choice that visually lightens the upholstered volume and reinforces the perception of overall softness.

Presented at the Salone del Mobile 2026, the Grant design sofa expresses a modular and flexible vision of the living area, built on formal continuity and compositional freedom.
