The Esosoft marks Antonio Citterio's first design for Cassina, a collaboration that announced itself with characteristic calm authority. The concept resolves a long-standing tension in furniture design: how to maintain structural clarity while offering genuine physical softness. A lightweight aluminum exoskeleton defines the silhouette from the outside, its geometry precise and unhurried. Within that frame, an organically shaped shell cradles generously proportioned cushions, producing a posture of ease that draws from the sensibility of 1960s Italian domesticity without quoting it directly. Eight configurable modules spanning compact sofas to expansive L-shaped compositions Collection includes benches, ottomans, and coffee tables for a coherent living environment Upholstery available in fabric and leather Aluminum exoskeleton with organically formed interior shell Citterio's approach here is one of controlled generosity. The system scales without losing its identity, and each configuration reads as a considered whole rather than an assembled collection of parts.
