Set of Four Steen Østergaard Dining Chairs A-Line 290, CADO, Denmark, 1960s.

Danish architect and industrial designer Steen Østergaard was decades ahead of his time with his futuristic Space Age designs. Through his innovative chairs, tables and other furniture, Østergaard elevated Scandinavian modern design during the mid-20th century.

Born in 1935, Østergaard studied furniture design and architecture at the School of Arts and Crafts in Copenhagen in 1957, graduating with honors in 1960. That same year, he won first prize in furniture design at the Danish Upholstery Guild’s annual awards, presented at Copenhagen’s Designmuseum Danmark.

From 1962 to 1965, Østergaard worked in the studio of revered furniture designer and architect Finn Juhl before establishing his own firm. Østergaard’s watershed moment came in 1968 when he created the iconic Cado 290 chair. Later produced in 1970 by Danish designer Poul Cadovius’s Cado company, the chair — a brilliant one-piece work of polyamide nylon reinforced with fiberglass by way of injection-molding — features an elegant form inspired by the stackable seats created by Danish designer Verner Panton, who started experimenting with the concept of single-piece plastic chairs in the late 1950s. However, unlike the revolutionary Panton chair, Østergaard’s design includes optional cushions that can be affixed directly onto the chair’s frame.

Another of Østergaard’s exemplary seating pieces is the President Meteor lounge chair designed in 1968 as part of Cado’s A-Line collection. The indoor and outdoor chair was originally produced in six colors — beige, brown, green, white, red and blue — and incorporates a molded plastic frame with a deep, upholstered seat. The lounge chair appeared in the original Star Trek television series and film Star Trek II: The Wrath of Khan and was used at NASA’s Johnson Space Center in Houston, Texas.

Østergaard is also known for furnishings such as his molded plastic dining room chairs, patio and garden furniture and ergonomic club chairs. In 1981, he designed and constructed the first Action Recliner chair, which included a built-in footrest, a piece now replicated around the world.

Østergaard’s furniture has been featured in exhibitions throughout Europe and the United States, including at the Museum of Modern Art in New York, the Deutsches Museum in Munich and Designmuseum Danmark.

While Danish furniture company Cado is popular among collectors of Scandinavian modern furniture for its well-crafted chairs, sofas, coffee tables and dining tables, the brand is best known for its sculptural wall shelving systems created by renowned Danish designer Poul Cadovius (1911–2011), Cado's founder.

The Copenhagen-born Cadovius initially studied to be an upholsterer and saddler before pursuing furniture design. He began his career in the 1940s making Venetian blinds and other window treatments before shifting his focus toward designing versatile furnishings that could be adapted to all sorts of interior spaces.

In 1945, Cadovius founded the furniture manufacturer Royal System intending to produce his designs for postwar homeowners. His visionary works included the 1948 Royal System shelving unit, a space-saving solution that underscored Cadovius’s penchant for problem-solving in a multifunctional way. Rather than balance shelves on wooden or metal legs, it held them to the wall with brackets. The wall unit was practical and functional, but it was also decorative, made of rich and exotic woods like walnut, rosewood and teak, a favorite wood of Cadovius’s and a highly sought-after material among mid-century modern designers. 

Cadovius established Cado in the late 1950s. The manufacturer followed the Royal System shelving unit with several other modular storage designs including the System Ultra in 1957, System Cado in 1960 and System Abstracta in 1962. Two years later, with more than 400 patents to his name, Cadovius purchased premier Danish furniture manufacturer France Søn and incorporated it into Cado.

Throughout the 1960s and 1970s, Cado collaborated with influential Danish and European designers of the era such as Steen Østergaard, best known for his stackable Cado 290, a Space Age fiberglass-and-polyamide nylon lounge chair; Finn Juhl, a stylistic maverick who embraced expressive, free-flowing shapes in chair and sofa designs much earlier than his colleagues; and Ole Wanscher, who drew on Shaker furniture and Chippendale forms and created the widely loved Colonial chair and coffee table for P. Jeppesens Møbelfabrik. 

Cadovius’s designs — as well as the other works manufactured by Cado — are widely coveted by vintage furniture enthusiasts all over the world. In 2018, the Danish brand dk3 reissued the Royal System as well as a more compact version.
