Poul Cadovius Rosewood Dinning Table with Aluminium Pedestal Base

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 Poul Cadovius is most famous for his modular floating shelving system, his career in design didn’t actually start with wall units.

Born just outside of Copenhagen in 1911, Cadovius began manufacturing window treatments in the 1940s with his partner, Hother Brønner. He soon turned his focus from Venetian blinds to furniture, finding success designing svelte pieces in teak, a richly colored hardwood favored by the Danish mid-century modernists.

In 1945, Cadovius founded the furniture manufacturer Royal System with his designs, including 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.

Cadovius followed the Royal System shelving unit with the System Ultra in 1957, the System Cado in 1960 and the System Abstracta, which was installed throughout the exhibition halls of the 1962 Cologne Furniture Fair. All expanded on his idea of wall-mounted shelving that saved space while offering functionality, allowing for limitless combinations of storage, shelves, work surfaces and other units. The Royal System proved to be especially popular and is still produced by Danish furniture brand dk3 today, with early models continuing to be in demand.

Along with the shelving systems, Cadovius designed everything from lounge chairs to mushroom-shaped bus shelters, and he held over 400 patents. In addition to being a designer, he was also an entrepreneur with an eye for opportunity, such as purchasing Danish manufacturer France & Søn in the mid-1960s and folded it into Cado, a company he founded years earlier. He used this as an occasion to experiment with his designs, conceiving such unusual pieces as an aluminum-based dining table topped with rosewood and hand-painted by artist Susan Fjedldoe Mygge.

Cadovius’s innovations in shelving continued throughout his career, with examples like the sculptural Butterfly shelf and vertical pieces mixing shelving and storage. In 2018, to celebrate the 70th anniversary of the Royal System, dk3 reissued the celebrated shelving system as well as a more compact version reimagined for 21st-century homes.
