Additional System Lounge Chair and Ottoman

Modules with unconventional shapes create seating arrangements where composition and adaptability take center stage. Designed by Joe Colombo in 1967, the Additional System is a modular concept with a timeless appeal, still strikingly “futuristic” more than fifty years later.

Its six cushion sizes, rooted in the ergonomic research of the 1960s, can be combined in countless dynamic configurations by adjusting both the number of pieces and their placement. The Additional System is offered in armchair, ottoman, and daybed variations, allowing for exceptional versatility.
