This article was written in order to understand rockers of today and to provide basic data of their designs and manufacture studying pattern changes in the West. This article contains, the characteristics of the style of the Adirondack rockers, the Mission style rockers in America and the European rockers. Adirondack rockers ($1850{sim}1940$) were made in various styles out of the mingling of rustic sensibilities with the formalism of Victorian designs. They were Old Hickory chair Co. style, Westport style, bentwood rocker style of two shape and Mottville rocker style. Mission style denoted American furniture design style of the early 20th century especially the work of Gustav Stickley and Roycroft Community. Mission style rockers had a simple, rectilinear style with exposed construction techniques, unpretentious materials (usually oak, with covering of leather, canvas or plain cloth) and little or no decoration. European rockers ($1660{sim}1918$) have come to mean rockers from the English regional chair, Thonet, J&J Kohn, Henry Van de Velde and Hoffmann. The modernism of modern furniture was affected by the characteristics of the Adirondack rockers, the Mission style rockers and European rockers.
