The Chesterfield armchair

In the United Kingdom a Chesterfield is a deep buttoned sofa, with arms and back of the same height. It is usually made from leather and the term Chesterfield in British English is only applied to this type of sofa.  In Canada the term "chesterfield" is equivalent to couch or sofa.
