This type of chair on wheels was devised by James Heath of Bath in around 1750 and for the next 75 years it rivalled the sedan chair in its popularity. It was mainly intended for use by invalids or elderly people.
This is an example of the commonest variety with two wheels joined by an axle beneath the seat, with a small pivoting wheel in front supporting it. The chair could be pushed from behind and steered by the long rod connected to the front wheels and controlled by the occupant. The whole chair was designed with flowing lines. The bath chair was especially popular in Victorian times and used at seaside resorts. Some bath chairs had sliding hoods to protect the traveller from wind and rain.
