While his mid-century Danish peers were working with wood, Poul Kjærholm (1929–80) found inspiration in the structural potential of steel. His innovative PK22 chair, designed in 1956 for E. Kold Christensen, offers a modern take on the style of ancient folding chairs through its 20th-century engineering. These Scandinavian Modern archetypical lounge chairs are in original cognac leather and remarkable condition. Because every element of the PK22 chair’s spare construction is visible, Kjærholm considered its aesthetics down to its exposed joints. Its immediate commercial success fueled Kjærholm’s career, and Fritz Hansen continues to manufacture the chair today.
