A couch, also known as a sofa, settee, or chesterfield, is a cushioned item of furniture for seating multiple people (although it is not uncommon for a single person to use a couch). It is commonly found in the form of a bench, with upholstered armrests, and often fitted with springs and tailored cushion and pillows. 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 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 which join at an angle of 90 degrees or slightly greater. Sectional sofas are used to wrap around walls or other furniture.
