AB Gustav Kahrs was founded in 1857, but not as a flooring manufacturer. Their primary product was spinning wheels, though they manufactured decorative and practical wooden products as well. By 1930, their product lines had evolved in another direction. At that time Kahrs was manufacturing furniture and had become Sweden's leading producer of wooden toys. In 1941, Kahrs obtained a patent on multlayer flooring as their interest in the engineered flooring market grew. Now their flooring can be found in such prestigious places as the National Opera House, Prague, Czech Republic, the Performing Arts Centre, St. Swithun's School, Winchest, UK, and the Van Palace, Beijing, China. Kahrs has three production facilities in Sweden and one in Norway, and all are certified to ISO 14001.
