The sedan chair was a popular form of non-wheeled transport in Europe until the 19th century. It was fitted with a seat for one person, and was carried by two or four chairmen (depending on the occupant's weight), who lifted it using two long poles that slotted into brackets on the side of the chair, attached to leather straps that hung round the chairmen's necks. Sedans were particularly useful for travelling through cities with narrow streets.
