The PK91 Folding Stool was designed by Kjaerholm in 1961 and incorporated flat spring steel bars and canvas or leather for the seat. The long sides of the frames formed the legs of the stool and were twisted like propellers for increased strength. In a traditional folding stool of the time, the legs were located on either side of the seat to minimize the distance spanned by the wood struts. But by twisting the legs, Kjaerholm's stool could span a wider distance and thus, he rotated the structure 90 degrees so that crossed legs formed the front and the back of the stool.
Our PK91 inspired Folding Stool incorporates all of the elements described above. In addition, we use 12mm satin-brushed 304 stainless steel for the frame with a 3mm corner radius. The seat is made with 2mm thick cowhide belting, covered with Premium Black Leather.
