PK80 is a daybed designed in 1957 by Poul Kjærholm for Fritz Hansen. The mattress is soft but firm, made of Hairlok with a foam core. The mattress is available in natural canvas or leather in a variety of colors. The cushion rests on a plywood base plate and the legs are made of satin-polished steel. The PK80 fits perfectly with Kjærholms PK31 series.

The inspiration behind the design comes from Bauhaus, which in turn was inspired by ancient Roman sofas. In PK80, Kjærholm has interpreted history and combined grand design with the absolute necessity of a resting place, resulting in this minimalist daybed. In 2004, the Museum of Modern Art in New York chose to furnish its galleries with the daybed, giving PK80 a place in design history.
