Rocking chairs have a rich history dating back to the late 18th century, when the word "rocking chair" was first included in the dictionary. The Shaker rocking chair was invented in New York in 1820, and the Boston rocking chair emerged in 1825. Throughout the years, the type of wood used to make rocking chairs has varied, with oak and maple being expected in the 1700s and mahogany being used in the 1800s. Rocking chairs were also made from wicker in 1860. Today, various styles of rockers are still being manufactured.
