Produced by Seguso Modern Murano Glass Coffee Table for Roche Bobois, 1990s

Members of the Seguso family have been leading figures in the manufacture of glass on the Venetian island of Murano since the late 1300s, but for most collectors of vintage design the name evokes two companies formed in the first half of the 20th century. Seguso Vetri d’Arte, born from a small consortium of master glass artisans that included Archimede Seguso (1909–99), thrived under the artistic directorship of Flavio Poli (1900–84), a designer with an eye for modern forms, color and pattern. Vetreria Archimede Seguso, meanwhile, was founded in 1946, when Seguso opened his own atelier in order to employ classical techniques in the making of modern glassware.

The owners of Seguso Vetri d’Arte were justly proud of their skills as craftsmen, but they were not worldly aesthetes — and they knew it. Poli had studied at the Art Institute of Venice, originally working in ceramics before switching mediums and taking up the art of glass. He introduced new simple forms to the genre — the best known of his designs being the Valva, which resembles a clamshell in profile — and employed several novel techniques such as corroso, which gives glass a rough, emery-board-like finish. Poli’s most collectible works are his sommerso pieces, made with a layering process in which clear and colored-glass vessels are “submerged” within one another, producing a kind of nesting-doll effect in striking, elegant vases with bands of separate and overlapped hues.

At his eponymous workshop, Archimede Seguso often favored highly decorative, age-old techniques employed with modern restraint. His layered-glass Losanghe vessels have the look of an abstract checkerboard while his free-form Merletto vases have delicate, lacy patterns created by painstakingly twisting two heated glass straws to create helixes around the walls of the piece.

Though different in their scope and mission, both of these furnaces bearing the Seguso name created some of the most beautiful, alluring and exquisitely crafted works in all of modern design.

In 1974, Roche Bobois opened its first showroom in the United States on Madison Avenue in New York City. The celebrated luxury French furniture brand is now in 50 countries with more than 200 stores.

The Roche Bobois story has origins in 1950, when entrepreneur Jacques Roche converted an old Paris theater into two contemporary furniture boutiques so that his sons could help usher stunning Bauhaus-inspired work out of the shops and into French homes nearby.

At another showroom called Au Beau Bois, also in the French capital city, the Chouchan family was simultaneously selling home furnishings. The families met later, when Philippe and François Roche convened with Patrick and Jean-Claude Chouchan at a furniture exhibition in Copenhagen in 1960 and afterward produced a catalog announcing their partnership.

Minimal and modernist Scandinavian design had gained prominence in the furniture industry by 1960, rendering designers such as Kaare Klint and Poul Henningsen marquee names — and Roche Bobois's principals had taken notice. Following a national advertising campaign in Elle magazine a year later, the Scandinavian furniture that the newly minted Roche Bobois was importing to Paris became a huge success. Early promotional material from the firm likely included the sleek modular wall units crafted in rosewood by Danish furniture maker Poul Cadovius. It didn’t take long for Roche Bobois to shift toward producing its own contemporary furniture line.

When the popularity of cable television took hold in more major American cities during the 1970s, sofas and other seating became integral to contemporary living-room decor. Roche Bobois’s newly launched Les Contemporains series positioned its own sofas front and center, and it also offered plush lounge chairs designed by Mario Bellini.

Bold works from the company during the decade included Marc Berthier’s Pop Art–colored tubular metal desks and chairs — the latter covered with braided fabric — as well as one of Roche Bobois’s most enduring and well-known pieces, the Mah Jong sectional sofa created by sculptor, painter and designer Hans Hopfer. Anchored by few central elements, this modular lounge sofa can be combined or stacked, giving the buyer total freedom over its appearance and the ability to maximize comfort.

Since its inception, Roche Bobois has worked with many internationally renowned architects and designers on its collections, among them Paola Navone and Vladimir Kagan. Even fashion designers such as Missoni and Emanuel Ungaro have made contributions to the company’s lineup.

In 2010, Roche Bobois marked its 50-year anniversary by debuting a partnership with French fashion designer Jean Paul Gaultier. A decade later, Roche Bobois teamed up with Portuguese artist Joana Vasconcelos, who designed a collection of organically shaped sofas as well as vibrant, colorful accent pillows and rugs.

Roche Bobois’s offerings over the years have included everything from mid-century modern armchairs to Art Deco case pieces to sculptural outdoor cocktail tables framed in metal wire — shop these classics now on 1stDibs.
