A chaise (the French for chair, through a transference from a sedan-chair to a wheeled vehicle) is a light two- or four-wheeled carriage with a movable hood or calash; the post-chaise was the fast-travelling carriage of the 18th and early 19th centuries. It was closed and four-wheeled for two or four horses and with the driver riding postillion.
