Creative Sofa Design

Types
The most common types of couches are the "loveseat", or British two-seater, and the settee or sofa, with two or more seats. A sectional sofa, often just referred to as a "sectional", is formed from multiple sections (typically two to four) and usually includes at least two pieces that join at an angle of 90 degrees or slightly greater, used to wrap around walls or other furniture. A sectional sofa is known as a corner sofa in the UK.
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.
