“Chesterfield” is an old term to describe a sofa or a couch. Generally, a chesterfield is a fancier sofa, and while some Canadians still call a sofa by that name, the term is outdated in most parts of the world. The most popular term used by Canadians is “sofa” while Americans are more inclined to use the term “couch.” Other terms, like “settee” and “loveseat,” are used to describe specific types of sofas.
