Interior designers will agree that small corner sofas were made for cozy small spaces. Perhaps it is not a small room, but a small area you want to devote to a snug haven for intimate conversation or reading, or whatever. A 2 or 3 person comfortable, soft, and proportionately sized sofa fits the bill.
If you have a need for a table in the center dividing the seating, a receptacle for drinks, or books, they are available in many styles and fabrics with the perfect table to accent your décor and a price tag to fit your budget. If you desire, you can put a standing lamp between the two pieces of a small sectional sofa. It has become trendy to place a standing piece of art in a corner flanked by small sections of sofa.
Some people prefer the solidarity of a one piece L shaped sofa and these are available also in small sizes. If you have a minimalist décor, you might want to consider this option. Even small sofas come with bells and whistles like heat, massage, reclining, and wired for light and sound.
Perhaps you require a firmer mattress on your seating area. That too is available in large variety. Sofas are made in a wide variety of countries. If you want to buy American, expect to pay the price and expect to get quality that will last a long time even if you have not opted for the regal leather social asset that immediately puts you in the upper class of furniture owners.
Luxury or cheap, soft or hard, brightly colored or subdued, elegant or modern, classic or avante guard, simplicity or baroque, wired or not wired, fabric or leather, the addition of a small corner sofa can enhance your living room ambiance. Look for small corner sofas wherever you shop.
