When was horse hair used to make furniture?

Horsehair has been used in furniture making since the 17th century, particularly for upholstery. It became particularly popular during the 18th and 19th centuries due to its durability and ability to retain shape. Horsehair was often used in cushions, mattresses, and as stuffing for upholstered furniture. Its use declined in the 20th century with the introduction of synthetic materials.
