Convert is a modular sofa system designed as an evolving platform—never a final composition. Built around seating modules, movable (or fixed) backrests, and movable storage platforms, it lets you reconfigure your layout over time as your space and routines change. Its deliberately discreet design language keeps the look calm and architectural, so every new arrangement feels intentional—whether you’re shaping an intimate corner, a generous sectional, or an open, multifunctional island for conversation and work.
Designed by SMPDO, Convert invites interaction and co-creation: a flexible foundation that adapts, transforms, and grows with you—at home in residential settings and dynamic public spaces alike.
