PK51™ and PK55™ are two rectangular tables designed by Poul Kjærholm in 1957. Both tables have an ash veneer table top that is is carried by a satin brushed stainless steel frame with four legs. The PK51 worktable was the first to be launched together with PK11™ as a matching set. Later, PK55 was launched as a smaller version of PK51.
