Zanotta Servofumo Low Ashtray in Steel by Achille and Pier Giacomo Castiglioni

Milanese industrial designer-architects Achille and Pier Giacomo Castiglioni (1918–2002; 1913-68) created some of the most iconic furniture designs in the world, particularly those that originated in the realm of mid-century modern lighting. 

In the late 1930s, after graduating from the acclaimed Polytechnic University of Milan, Pier Giacomo opened a design studio with his brother Livio and likeminded architect Luigi Caccia Dominioni. Achille, also a graduate of Milan Polytechnic, joined the group after completing his studies in 1944. The era’s architects were encountering difficulty in their attempts to secure building commissions, so the group focused on designing practical everyday objects such as the Model 547, a tabletop radio for Phonola that was encased in Bakelite. 

The Castiglioni brothers produced wildly popular and innovative designs throughout the 20th century. While Livio departed the practice in 1952 to pursue lighting design and sound technology on his own, Pier Giacomo and Achille would continue to collaborate on a wealth of projects in the ensuing years. 

Vintage furniture collectors may be familiar with Livio and Italian designer Gianfranco Frattini’s serpent-like Boalum lamp, while Achille’s Taraxacum hanging lamp — created for FLOS with sprayed plastic polymers originally intended for military use — as well as the Arco, Snoopy and Toio lamps, which were the result of the collaboration between Pier Giacomo and Achille, are milestones in modernist lighting design. 

Also for FLOS, Pier Giacomo and Achille created a series of metal frames that, wrapped in the polymer, became floor lamps (Gatto) or pendant lights (Viscontea and Taraxacum), all released in 1960. The Gatto floor lamp takes its name from the Italian word for “cat” and the inspiration for its aesthetic from lighting that George Nelson developed for legendary American furniture manufacturer Howard Miller during the 1940s. Around the same time, the designer Tobia Scarpa (son of the famed Italian architect Carlo Scarpa and one-half of the widely revered postmodern husband-and-wife design duo Afra and Tobia Scarpa) created a floor lamp called Fantasma (1961) using the polymers technique. FLOS continues to make the Castiglionis’ innovative pieces today.

In addition to their provocative lighting works, Pier Giacomo and Achille also created stereo systems, decorative objects, seating, tables and other items for the likes of Brionvega, Alessi, Zanotta, Kartell and more.

Entrepreneur Aurelio Zanotta founded Zanotta in 1954 in Nova Milanese, Italy. Originally called Zanotta Poltrona, it specialized in traditional furniture. By the early 1960s, however, Zanotta had established a reputation for edgy mid-century modern design. Today’s vintage furniture collectors know the brand well for its innovative and wholly sculptural chairs, coffee tables and more.

One of Zanotta’s earliest successes was the Mezzadro stool — better known as the Tractor stool — designed by Pier Giacomo Castiglioni and his brother Achille in the late 1950s. In 1965, Zanotta was among the first furniture companies to work with expanded polyurethane foam and frameless construction, such as for the Throw-Away sofas and armchairs designed by Willie Landels. Another popular design was the Blow chair — designed by Jonathan De Pas, Donato D’Urbino, Paolo Lomazzi and Carla Scolari — viewed by many as a physical expression of late '60s carefree culture.

In 1969, amid the provocative movement we now call Italian Radical Design, Zanotta’s Sacco chair garnered major attention. The boundary-pushing beanbag chair was the brainchild of designers Piero Gatti, Cesare Paolini and Franco Teodoro who presented it to Aurelio Zanotta as a transparent vinyl sack loosely filled with small polystyrene balls. He suggested its signature brightly colored leather.

The Sacco chair won the 1970 ADI Design Museum’s Compasso d’Oro award. In 1972, the Museum of Modern Art in New York included it in the landmark exhibition “Italy: The New Domestic Landscape” curated by designer Emilio Ambasz. In 2020, it received a Compasso d’Oro ADI Lifetime Achievement Award for 50 years of enduring popularity. It is now in museum collections around the world including the Triennale Design Museum of Milan, the Musée des Arts Décoratifs in Paris, and London’s Victoria Albert Museum.

After Aurelio Zanotta died in 1991, the company remained in his family and has been run by his three children since 2002. Zanotta continues to set the bar high for furniture design with trend-setting pieces.
