Other couch variants include the divan, the fainting couch (backless or partial-backed), the chaise longue (long with one armrest), the canapé (an ornamental 3-seater), and the ottoman (generally considered a type of footstool). To conserve space, some sofas double as beds in the form of sofa-beds, daybeds, or futons. There are also couches known by genericized trademarked names, such as a davenport or Chesterfield (named for one of the Earls of Chesterfield).
The term "chesterfield" is a Canadian term equivalent to couch or sofa. The use of the term has been found to be widespread among older Canadians. This term is quickly vanishing from Canadian English according to one survey done in the Golden Horseshoe region of Ontario in 1992. In the United Kingdom, the word refers to a particular style of sofa featuring a low rolled back and deep buttoning.
The term "three-piece suite" is used to describe a furniture set consisting of a two or three-seater couch and two armchairs. Other less specific terms for sets with at least one sofa include "chesterfield suite", "lounge suite", "living-room suite" and "sofa suite".
