Lounge Chair

A chair designed for extended seating in a relaxed posture — Eames Lounge (1956), Wegner Wishbone, Hans Wegner Papa Bear, le Corbusier LC4 chaise. The design typology where ergonomic ambition reaches its most public expression and where named historical exemplars define the type to a degree no other chair category matches. The lounge chair is a cultural object first; it just happens to be sat in.
