Mahogany curvilinear chair featuring a leather covered “springy” seat with horsehair interior padding.
It was used for posting exercise, to maintain riding muscles, on inclement days. For 20 or 30 minutes, the “rider” sat upon and bounced up and down on the Chamber Horse. A sliding safety bar was secured across the chair arms to avoid being “pitched-off the wild horse.” To slow the critter, all that was required was to stop moving one’s legs.
Exercise was obviously a different matter in the days before electrical fitness equipment and personal trainers!
