Blonde Girl Undresses On The Couch

Etymology
The traditional meaning of couch is a particular type of sofa with a half back and one raised end. By this definition it more closely resembles a daybed, chaise longue, or indeed a bed. In the UK, where the generic term for the item of living room furniture is usually "sofa" or "settee", the term "couch" retains this specific meaning, for example in a therapeutic setting (e.g. a psychiatrist's couch). A couch is therefore used while lying down, while a sofa or settee is for sitting upright. The word "couch" derives from Old French couche, meaning "bed", and from coucher, meaning "put to bed, lay down".
