Classic Fern Sofa Black from Byarums Bruk became popular after the World Exhibition in London in 1851 and quickly became a common feature in English parks and gardens. Its popularity spread to Sweden, and today Byarums Bruk is the only foundry still producing this classic sofa. Its timeless design and popularity were confirmed when the design brand supplied several sofas to Count Lennart Bernadotte's park and castle Mainau in southern Germany during the 20th century.
