PK91 Folding Stool by Poul Kjaerholm for E. Kold Christensen, 1961

Iconic PK91 stool designed by Poul Kjaerholm and a first production manufactured by Ejvind Kold Christensen, Denmark 1961. This foldable stool has a matt chrome plated steel frame which is foldable due to an ingenious joint structure in the middle of the cross. The structure of the stool is slightly twisted so when it is in folded position, it fits perfectly against each other. This stool might seem simple but the way this is constructed is absolutely amazing. The design probably took a long time to perfection as the full weight of the person sitting on is rests solely on the canvas seat and the joint structure which keeps the frame together. It has to be incredibly strong and well thought to work as perfectly as it does. The frame is obviously made of solid steel which can take a lot, but still. The stool is in fully original condition with its original canvas seat which has a nice original patina from years of use. The matt chrome plated structure is also in very good condition with normal age-related wear. The stool is not stamped but many early productions weren’t. This was purchased together with other Kjaerholm pieces coming from the same house, all early E. Kold Christensen productions.
