Armchair (model 4814)

Anna Castelli Ferrieri was an Italian designer and architect who pioneered modular furniture systems in the postwar period. Working primarily in plastic and metal, she developed stackable, reconfigurable storage units and seating that prioritized flexibility and spatial efficiency for compact urban living. Her designs for Kartell, the Milan-based plastics manufacturer, established her as a central figure in the development of injection-molded furniture. Ferrieri's approach combined industrial production with refined modernist form, making advanced design accessible to a broad market.
