20th Century Gerrit Rietveld Armchair Model 635 Red and Blue for Cassina in Wood

With its geometric composition and primary colors, the Red and Blue armchair has become the definitive symbol of the Dutch De Stijl (“the Style”) movement. The chair’s creator, Gerrit Rietveld (1888–1964), was perhaps an unlikely pioneer of this revolutionary aesthetic movement given his traditional path to making furniture. The son of a carpenter in Utrecht, Rietveld left school at age 11 to begin an apprenticeship with his father. Later, he attended night school and worked for a goldsmith. In 1917, Rietveld opened his own furniture workshop.

Although he trained as a cabinetmaker, Rietveld’s interests eventually grew beyond craftsmanship, and he began to focus closely on the intellectual concepts of design. He built objects from minimal materials and believed that a chair could provide more than rest for the body; the greater goal — the one he set for this chair — was to provide for the “well-being and comfort of the spirit.” On the underside of the seat he inscribed, “When I sit, I do not want to sit as my seated flesh likes, but rather as my seated spirit would sit, if it wove the chair for itself.” 

Designed in 1918, the original Red and Blue armchair was neither red nor blue — it was made of beechwood. But in its geometric precision, the piece embodied the modernist De Stijl philosophy to achieve postwar harmony through a rigorous aesthetic of pairing basic shapes with a minimal color palette. Rietveld designed the chair using only wood that had been cut in standard, readily available sizes. In doing so, he hoped it would one day be mass produced. This move toward an ethos of industrialization was pure De Stijl, and would later influence movements like Bauhaus and International Style. Writer and architect Theo van Doesburg, who cofounded the movement with the artist Piet Mondrian, featured Rietveld’s chair in De Stijl, the magazine he edited and published that launched alongside the Dutch movement.

It wasn’t until approximately 1923 that Rietveld painted the chair in the colors it is known for today — the colors most frequently associated with Mondrian and De Stijl. In addition to furniture and decorative objects, Rietveld designed 100 buildings throughout his career but only one outside the Netherlands. By far the most important is the Rietveld Schröder House (1924), considered the only house built completely on De Stijl precepts. Cassina manufactures the Red and Blue chair today, and the ingenious simplicity of Rietveld’s construction continues to challenge designers as often as it delights them.

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.
