Set of six Break 401 armchairs by Mario Bellini for Cassina, 1976

Milan-born architect and designer Mario Bellini just may be the closest thing to a modern-day Renaissance man: His creative output spans genres, from electronics to furniture to architecture to cars, comprising iconic designs in each. Vintage Mario Bellini sofas, dining chairs and other seating pieces are widely coveted, and the designer has been the recipient of multiple prestigious Compasso d’Oro awards. More than 20 of his works are in the permanent collection of the Museum of Modern Art.

Born in 1935, Bellini studied architecture at the Polytechnic University of Milan before founding his own firm in his native city in the early 1960s. He soon branched out beyond architecture, however, first for the tech manufacturer Olivetti, where he served as chief industrial design consultant from 1963 to 1991. During that time, Bellini oversaw the design of some of Olivetti’s most popular typewriters.

His penchant for electronic design didn’t stop there: Bellini also designed cameras for Fuji, televisions for Brionvega and a slew of audio devices for Yamaha, then served as design consultant for Renault and devised the interior of the 1980 Lancia Trevi for Fiat. Meanwhile, his architecture work spans continents, including such modern gems as the Museum of Islamic Arts at the Louvre, the National Gallery of Victoria extension in Melbourne, the Dubai Creek Complex and the Milan Convention Centre in his hometown.

And then there’s the furniture: Over the last 70 years, Bellini has designed office furniture for Vitra; lamps for Artemide, Erco and FLOS; porcelain for Rosenthal and long-admired sofas and other seating for Kartell, Natuzzi, B&B Italia, Cassina and more.

His oft-imitated 1977 Cab chair for Cassina, comprising 16 individual pieces of saddle leather that create a “skin” over a minimal metal frame, remains one of the manufacturer’s best sellers today. His pudgy-legged, round tables for Cassina foreshadow Faye Toogood’s widely loved Roly Poly line. His postmodern Summa armchairs for Kartell, as well as his elegant Chiara floor lamp, still lure collectors on vintage furniture websites.

Bellini’s most famous contribution to furniture design, though, may be his 1970 Camaleonda sofa for B&B Italia (then C&B Italia). An entrant to the 1972 MoMA show “Italy: The New Domestic Landscape,” the seat takes its name from the Italian words for chameleon and wave. Its bulbous, modular form makes it infinitely flexible. The sofa was a runaway hit at the show and, once discontinued, remained so popular among vintage dealers that B&B Italia reissued it in 2020 with all recycled materials and interchangeable seat covers. “Of all the objects I have designed, Camaleonda is perhaps the best in terms of its sense of freedom,” Bellini said.

Furniture manufacturer Cassina is a prolific design house for more reasons than one: It not only owns the licenses to an exquisite collection of iconic chairs, sofas, tables and other pieces from the 20th and 21st centuries but also produces original works that are characterized by innovation and the finest Italian craftsmanship.

Cassina’s illustrious legacy includes being one of the first companies to bring industrial design to Italy in the 1950s. Founded in 1927 in Meda, Italy, by brothers Cesare and Umberto Cassina, the Italian manufacturing giant originally specialized in bespoke woodworking. In nearly a century since its founding, the company has shown incredible foresight about design trends and the evolution of technology.

In 1964, Cassina signed an exclusive licensing agreement to manufacture furniture by Le Corbusier and his collaborators — such as the LC4 chaise longue made with trailblazing French modernist Charlotte Perriand and Pierre Jeanneret — a move that would shape the future of the company. Cassina’s I Maestri collection is an ongoing initiative to restyle landmark designs from the 20th century, such as pieces by Gerrit Rietveld (the Red and Blue armchair from 1918), Charles Rennie Mackintosh, Erik Gunnar Asplund, Franco Albini and Frank Lloyd Wright. The company preserves the intentions and original styles of their designs but adds updated techniques, materials and processes — rendering them the best possible combination of past, present and future. The brand has also worked with contemporary icons like Zaha Hadid, Gio Ponti and Philippe Starck.

Cassina’s original designs are cutting-edge as well. They include pieces for everyday use, the development of which is guided by comfort and the marriage of Italian craftsmanship with industrial technology.

Some of Cassina’s pieces, both from its contemporary and I Maestri collections, can be found in the collections of museums like the Museum of Modern Art and the Vitra Design Museum. In 2014, the company became part of Haworth in its acquisition of Italian furniture group Poltrona Frau, and in 2015, Spanish designer Patricia Urquiola joined Cassina as its art director, leading the brand into its next century of inventive style.
