Black Sofa

A couch, also known as a sofa, settee, or chesterfield, is a cushioned item of furniture for seating multiple people. 

Although a couch is used primarily for seating, it may be used for sleeping. In homes, couches are normally put in the family room, living room, den, or lounge. They are sometimes also found in non-residential settings such as hotels, lobbies of commercial offices, waiting rooms, and bars. Couches can also vary in size, color, and design.

The most common types of couches include the two-seater, sometimes referred to as a loveseat, and the sofa. The loveseat is designed for seating two people, while the sofa has more than two cushion seats. 

A furniture set consisting of a sofa with two matching chairs is known as a "chesterfield suite" or "living-room suite". In the UK, the word chesterfield was used to refer to any couch in the 1900s. A chesterfield now describes a deep buttoned sofa, usually made from leather, with arms and back of the same height.
