In 1940, Charles Eames and Eero Saarinen made this reading chair for the NY Moma's competition "Organic Design in Home Furnishings". Due to the lack of techniques, it couldn't go into series production; it was made with plywood and foam rubber. It was impossible to shape seats with organic forms and make large quantity of them, until the 1950s. They continued to develop the idea of an organic seat, could molde them in fiberglass and finally manufactured them.
In his further development for the organic seat, Eero Saarinen made the famous Tulip Chair, in 1956. The resemblances with the previous chair are clear, but he put just one leg. He achieved his ideal of formal unity: "every piece of furniture from the past has a holistic structure".
