FREDERICIA Soborg Chair Wood Frame In 1950, Børge Mogensen introduced the prototype of the Søborg Chair. His fusion of functionalism, expertise in cabinetmaking and use of new production techniques led to a remarkably simple chair that could be manufactured industrially. Merging his signature love of solid wood with his newfound passion for plywood shells, Mogensen crafted the Søborg Chair with soft rounded corners and gentle lines in a timeless design that appears light yet solid, with an ample-sized seat and back to ensure endless hours of comfort.
