The PK9 Dining Chair, frequently referred to as the "Tulip," represents a masterful evolution of the three-legged form. Poul Kjærholm designed this piece with unique structural integrity, where three curved bands of satin-brushed spring steel converge to form a central column before branching out to cradle the seat. The shell itself is a study in ergonomics; its distinct curvature was finalized after the designer's wife, Hanne Kjærholm, sat in boxes of clay to capture the perfect imprint for lasting comfort. Fully wrapped in premium leather, the seat creates a soft, organic contrast to the cool precision of the steel base, resulting in a silhouette that is both fluid and supportive.
