The source of inspiration for the PK91 is an ancient Egyptian folding stool that dates back to ca. 1500 BC. The designer’s method of refining historical furniture types has again been put into play and the result is unmistakably a Kjærholm classic, with the stool’s minimalistic and elegant expression. The PK91 is part of the permanent collection at the Röhsska Museum in Gothenborg, in Sweden. The folding stool is available with a leather or canvas seat and the base is in satin-brushed stainless steel.
