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.

Penny Sparke (living — quote)

The pieces designed by Magistretti, Gardello, the Castiglioni brothers, Vigano and others at the 1946 RIMA exhibition of Popular Furnishings were simple and inexpensive, modelled on traditional types such as the deck chair and the safari chair.

Sparke, *Design in Context* (Bloomsbury, 1991 [first published Quarto, 1987]), Chapter 6, 'Italy: Style and Individualism,' on the postwar Italian RIMA (Riunione Italiana Mostre Arredamento) exhibition of Popular Furnishings. The Magistretti / Castiglioni / Castiglioni-brothers lineage Sparke names here continues through the 1981 Sindbad armchair (Vico Magistretti for Cassina) and the Memphis-era postmodern lounge — thirty-five years from austere postwar deck-chair revival to arch-clever Memphis fancy.
