Adirondack chairs were invented in 1903 by Thomas Lee in Westport, New York, near the Adirondack Mountains. Lee designed them for his family’s summer home, aiming for a comfortable chair that worked well on uneven terrain. He crafted a wooden chair with a slanted back and seat and wide armrests, providing stability and relaxation. A friend, Harry Bunnell, later patented the design in 1905 and began producing them. The original “Westport chair” evolved into the Adirondack chair we know today, becoming a symbol of outdoor leisure and rustic charm.
