"The Adirondack chair was not always known by that name. According to the Adirondack Museum in Blue Mountain Lake, New York, it started its life as the Westport chair named after a small town close by the Adirondack Mountains on the edge of lake Champlain.
Thomas Lee first worked out the design of the chair around 1900. Vacationing at his family's house Stony Sides, along with some 22 relatives, he set about designing a truly conformable outdoor chair
Nailing boards together on the front lawn, he asked other members of his family to test prototypes and tell him which were the most comfortable. With this research as a guide, he built a chair with a sloping seat and back. Each chair was made from a single pine board and with the wide armrests that became a hallmark of the Adirondack style. His chair was an immediate success with the family."
