Coen de Vries (b.1918) was a Dutch industrial designer.
From 1940 until 1946, he studied interior design at the Royal Academy of Fine Arts in The Hague.
After graduating, de Vries established his own store named ‘De Sleutel’ (The Key) in Amsterdam. Here he produced and sold his own designs as well as others, making him the first Dutch interior architects to do so. He produced practical, yet modern furniture at an affordable price in light woods with simple construction and upholstered in brightly colored fabrics.
The philosophy behind ‘De Sleutel’ was in line with the views propagated by the association ‘Goed Wonen’.
As a member of 'Goed Wonen', Coen de Vries belonged to the post-war generation of designers who left their mark on the development of Dutch furniture and interior after 1945.
Founded in 1946, the association ‘Goed Wonen’ (Good Living) was a design and industry partnership that was committed to postwar reconstruction and quality-of-life improvements through good design. The group forged many strong collaborations between artists, designers, architects, manufacturers, and customers, which resulted in widespread interest in modernist design principles and aesthetics in the Netherlands.
In addition to his work for Goed Wonen, de Vries was often commissioned for the construction of private residential buildings and renovations of interiors.
From 1966 to 1972, de Vries was a member of the Council for the Arts, a national advisory board to the Minister of Culture, and from 1977 to 1980 he was a member of the Committee on Architecture of the Amsterdam Arts Council.
