The CH25 is one of the first four chairs Hans J. Wegner created exclusively for Carl Hansen & Son at the beginning of the collaboration which started in 1949. The chair, considered revolutionary at the time, was put into production in 1950. The woven paper cord, a replacement for seagrass developed during World War II, had not been used in furniture before. However, Wegner was enthusiastic about the look of the material and its non-stretching and optimal durability, and so were generations after him.
