Designed by Anna Castelli Ferrieri in 1969 and featured in MoMA’s 1972 exhibition Italy: The New Domestic Landscape, the cylindrical stacking units have stayed in production for over 55 years without a single revision — which is itself the argument for one. The modular system lets a single unit grow into a column of three, scaling storage without changing the visual language. New colorways like Burgundy plant it firmly in current home aesthetics without chasing trends.
