The PK20 is a comfortable and elegant lounge chair. PK20 rests on a flexible matt-chromed spring steel frame. The original idea was to use spare leather strips from the production of other leather furniture in order to optimize production. Due to the diversity of the leather strips, the idea was rejected and today, only the finest leather strips are used. The low back version of the PK20 is included in the permanent collection at the Victoria and Albert Museum in London. PK20 is available in wicker and leather. The leather version also includes a leather headrest.
