The word wicker or "wisker" is believed to be of Scandinavian origin: vika, meaning "to fold" in Swedish, and vicker, meaning willow.

The distinctive braid pattern is called Wiener Geflecht, Viennese Braid, as it was invented in 18th century Vienna and later most prominently used with Thonet coffee shop chairs.
