Types
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, or 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.
