The PK25™ was designed by Poul Kjærholm 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 Kjærholm’s eagerness to work with common, industrial materials. Kjærholm 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.
