Are there technical differences between a sofa a couch and a davenport? Or are these merely regional/cultural names for the same thing? I grew up saying “couch”, though I’ve gravitated toward “sofa” in recent years. I’ve only ever heard a few people say “davenport”.
I suppose I could ask the same question about “bureau” vs “dresser” vs “chest of drawers”.
Davenport: a large sofa, often convertible into a bed. (A writing desk is a second meaning.)
Divan: A long backless sofa, especially one set with pillows against a wall. (I grew up referring to one of these as a daybed.) (There are also three other definitions having nothing to do with sofahood.)
Sofa: A long upholstered seat, typically with back and arms.
Chesterfield: [After a long discourse about the Earls of Chesterfield and their tastes, the following note occurs]
Couch: A sofa. (A note indicates that it is the term of choice in reference to the object used for reclining while undergoing psychotherapy.)
Loveseat: A small sofa or chair that seats two people.
So the terms appear to be synonymous, with several having specific connotations.
