A sofa is a large piece of furniture that typically seats three or more people, and it is often the centerpiece of a living room or den.
A sofa is typically much longer and wider than a loveseat, and it can take up more space in a room.
Sofas come in a wide range of styles, from traditional and formal to modern and casual, and they can be upholstered in a variety of fabrics, including leather, velvet, and microfiber.
