Robin Day

British industrial designer Robin Day (1915–2010) was a pivotal figure of post-war European modernism, dedicated to creating affordable, high-performing furniture through advanced mass production. Trained at the Royal College of Art, Day gained international renown after winning the 1948 Low-Cost Furniture Competition at MoMA in New York. Day established a legendary, multi-decade partnership with British manufacturer Hille, beginning with his ply-and-steel 675 Chair in 1952. In 1963, Day revolutionized global seating with the Polypropylene Chair. Engineered from a single injection-molded shell mounted on tubular steel legs, it became the world's first mass-produced plastic chair, selling tens of millions of units for schools, stadiums, and transit hubs. His work is preserved by design institutions and reissued by brands including Case Furniture.
