This chair emerged as a commission from Walter Dorwin Teague Associates for the Gas Pavilion at the 1964 World's Fair in New York. Three hundred of these chairs were used at the Festival '64 American Restaurant in the pavilion. The chair is closely linked to the United Airlines chair and was placed on a steel base that was originally designed for the Flexible Radius seating. The seat is made of individual segments and is vaguely reminiscent of the shell of an armadillo. The segments were made of an urethane foam that formed a smooth skin when heated with natural gas (thus the link to the theme of the pavilion). In this chair, the industrial manufacturing process of furniture cushioning that had served as the basis for the design of the Marshmallow sofa was realized.
