The PK25 was designed by Poul Kjaerholm in 1951, for his final graduation project at the School of Applied Arts in Copenhagen.  The PK25, also known as the "Element" Chair, is a fine example of the young Kjaerholm's eagerness to work with common, industrial materials. Kjaerholm was determined to reduce the chair to a single piece of each material, resulting in the overarching hallmark of the chair: The continuous and rather complex steel frame that is bent in a single piece without joints and connections. The PK25 is available in natural or black flag halyard combined with a matt chromed spring steel base.
