A fainting couch is a modern term describing a couch with a back that is traditionally raised at one end. The back may be situated completely at one side of the couch or may wrap around and extend the entire length of the piece much like a traditional couch. However, so-called "fainting couches" are easily differentiated from more traditional couches, having one end of the back raised.[1]
The style of couch referred to popularly as "fainting couches" were popular in the 19th century as a revival of ancient furniture styles.[1]
