The CH25 lounge chair, like many of Hans J. Wegner’s other iconic designs, is clean and simple in its distinctive shape. But its introduction caused a stir due to Wegner’s choice of materials on the backrest and seat. 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.
