The PK9 is a side chair also known as the "Tulip chair" due to its unique shape. The shape characterized by the three pieces of satin-brushed stainless steel that act as a column, a set of legs and carriers of the leather seating element. The story of the design is about Poul Kjaerholm's uncompromising quest for the perfect shape. The inspiration for the shape of the shell comes from the imprint of his wife's, Hanne Kjaerholm, behind in the sand on the beach. Later, during the design process, Hanne Kjaerholm sat in boxes of clay to find the most optimal and comfortable solution. PK9 matches the PK54 table perfectly. The PK9 chair is fully upholstered in a limited selection of leather. Tthe base is made of satin brushed stainless steel, while the inner shell is made of nylon.
