A sofa is a comfortable and versatile piece of furniture designed for seating multiple people. It typically features a cushioned seating area with soft upholstery, supported by a sturdy frame, often made of wood or metal. Sofas come in various styles, sizes, and fabrics, including leather, fabric, and velvet, to match different interiors. Ideal for living rooms or lounges, they offer both relaxation and style, becoming a focal point in any home decor.
