Gianfranco Frattini Space Age Leather “Sesann” Living Room Set for Cassina, 1972


The Sesann lounge was designed by Gianfranco Frattini in 1970 and produced by the Italian manufacturer Cassina. This set upholstered in black leather is composed of a two-seater sofa and two lounge chairs.

The leather is its original one restored, it presents some scratches, but the structure and the foam are in perfect condition. The chromed tubular cage is in excellent condition, too, without rust or oxide.

Sesann is characterized by an organic and informal shape and is defined by the tubular metal detail that wraps around the soft, upholstered seat. In the 1970s, the Cassina catalog contained inside two space-age chromed living room solutions: “Soriana” series by Afra & Tobia Scarpa and “Sesann” series (composed of a two seater sofa, a three-seater sofa, a lounge chair, and a coffee table).

Gianfranco Frattini (May 15, 1926 – April 6, 2004) was an Italian architect and designer. He is a member of the generation that created the Italian design movement in the late 1950s through the 1960s. Gianfranco Frattini was born in Padua, Italy on May 15, 1926. He graduated with a degree in architecture from the Politecnico di Milano in 1953. Frattini opened his professional practice in Milan after having worked in the office of his teacher and mentor Giò Ponti. Frattini became an industrial designer by default when he lacked appropriate lighting and furniture for his interiors. His collaboration with Cesare Cassina for his namesake company started in 1954, followed by partnerships with many other manufacturers, such as Bernini, Arteluce, Acerbis, Fantoni, Artemide (for whom among others pieces with Livio Castiglioni he designed the historic Boalum lamp), Luci, Knoll, Lema and many others. In 1956 he co-founded Associazione per il Disegno Industriale, and throughout his career, he practiced both industrial design and architecture, mainly focusing on interiors. He was a board member of the Triennale. Great connoisseur of wood craftsmanship, he forged a long and fruitful professional partnership with the master craftsman from Bovisio Masciago (Milan), Pierluigi Ghianda. Glassware designed by Gianfranco Frattini for Progetti is in the permanent collection of the Museum of Modern Art, and the Boalum lamp (with Livio Castiglioni) produced by Artemide is in the collection of the Smithsonian, Cooper-Hewitt National Design Museum.
