Modules with unusual shapes give life to original seating configurations where aggregation and variability take center stage. Additional System is a project by Joe Colombo from 1967, reimagined today by Tacchini while respecting its original spirit: a modular system with timeless allure, still “futuristic” even 50 years later. Cushions of six different sizes, inspired by ergonomic studies of the 1960s, come together in dynamic and flexible combinations created by varying the number of elements and how they are positioned. Additional System is available in armchair, pouf, and daybed versions.
