A sedan chair is a type of portable chair used for transportation, typically carried by two people. It consists of a seat enclosed by a frame, often with a canopy for protection against the elements. Historically, it was popular in the 17th to 19th centuries, especially in urban areas where roads were not suitable for vehicles. Sedan chairs were commonly used by the wealthy, allowing them to travel comfortably without walking. They were often seen in cities like London and Paris, where they provided a convenient way to navigate crowded streets. Today, they are mostly of historical interest and are sometimes used in parades or reenactments.
