PK11 is a complex and beautiful chair carried by a three-legged satin brushed stainless steel frame. The chair was designed by Poul Kjaerholm in 1957 as a companion to the PK51 worktable designed that same year. Together, the two parts were originally designed as a matching set.

Poul Kjærholm had a particular interest in various construction materials; especially steel, which he considered a natural material. He was a trained carpenter who continued studies at the Danish School of Arts and Crafts. He moved on to work at Fritz Hansen, for about a year, where he designed a number of noteworthy chair prototypes. In 1955, Kjærholm started collaborating with manufacturer Ejvind Kold Christensen, which lasted until his death in 1980. In 1982, Fritz Hansen took over the production and sales of "The Kjærholm Collection", developed from 1951 to 1967, designs, which are logical to the minute detail with an aura of exclusivity.

PK11 armchair features a satin-brushed stainless steel frame with a lacquered ash arm and backrest. It is upholstered in a limited selection of leathers.
