The F10 Chaise Lounge from 1968 is one of Antti Nurmesniemi most striking and iconic furniture designs. Created for Finnish manufacturer Cassina Oy, it reflects Nurmesniemi’s disciplined modernist aesthetic combined with a sculptural, almost futuristic form. The chaise features a curved, tubular steel frame supporting a black leather seat that appears to float, emphasizing both lightness and precision. With its ergonomic shape and industrial materials, the F10 embodies Nurmesniemi’s belief that comfort, function, and visual clarity could coexist within the language of modern design.
