Description from the Metropolitan Museum of Art:
Revolving chairs, also known as stools or swivel chairs, were produced by Shakers in many styles and sizes. The earliest examples stood on long legs and often were used in the brethren’s shops. Low revolving chairs, such as this example, with Windsor-like comb backs were rarely made before 1840.
