stapel, a 1949 horgenglarus in-house construction, anticipated the 1950s' use of shape with its new free lifestyle. Its characteristic kidney shape contrasts stapel to the then-popular Carpenter style in Switzerland. The robust chair's name says it all—this solid wooden chair is perfectly easy to stack. Its manufacturing process is particularly complex because its rear legs are turned in different diameters prior to bending. Front, as well as rear legs, are also used in Max Bill's kreuzzargenstuhl launched two years later. This chair has recently been re-interpreted with a larger seat frame and a more pronounced curved shape.
