A couch or sofa is a piece of furniture for seating two or more people in the form of a bench, with or without armrests, that is partially or entirely upholstered, and often fitted with springs and tailored cushions.Although a couch is used primarily for seating, it may be used for reclining and napping.
In homes, couches are normally found in the family room, living room, den, sitting room or the lounge. They are also found in hotels, lobbies of commercial offices, waiting rooms, furniture stores, etc.
The term couch is used in North America and Australia, whilst the term sofa is generally used in the United Kingdom. The word originated in Middle English from the Old French noun couche, which derived from the verb meaning “to lie down”. It originally denoted an item of furniture for lying or sleeping on, somewhat like a chaise longue, but now refers to sofas in general.
The most common types of couches are the loveseat, designed for seating two persons, and the sofa, with two or more cushion seats. A sectional sofa, often just referred to as a “sectional”, is formed from multiple sections (typically two, three, and four) and usually includes at least two pieces that join at an angle of 90 degrees or slightly greater, used to wrap around walls or other furniture.
