English exercise chair, 19th century
Made from mahogany and leather and measuring just over 2 m high, this exercise chair was said to offer the equivalent of riding a horse. Known in the 1800s as a chamber horse, the user sat on the seat and bounced up and down on the concertina springs as if trotting on a horse. Horse riding was considered a form of healthy exercise. Judging by the materials and its size, the chair was probably owned by someone who was wealthy.
