During a Danish furniture trade show, Dr. Eigill Snorrason critiqued the industry for not paying enough attention to ergonomics. The Swivel Chair (1955) Wegner’s rejoinder of sorts, an elegant backrest of hand-carved wood that’s been compared to a gently bent propeller. The smooth lines, thin profile and wheels invite a sure-footed slide across any office. Manufactured by PP Møbler. Photo by Jens Mourits Sørensen.
