Kjaerholm's 1961 masterpiece, the PK91 stool made by E. Kold Christensen is the perfect distilation of his aesthetic. A minimalist form combining matte chrome-plated steel and leather, the elegant propeller shape to the legs and precisely machined hinge allows the stool to fold flat when not in use.
