Sofa and couch are two words that mean the same thing; Ethan Allen calls both sofas. Loveseats are the sofa's little sibling, also sometimes called small sofas or apartment sofas. The only difference between the two is their size. At Ethan Allen, sofas come in three size ranges: Small: 70 to 79 inches long Large: 80 to 89 inches long Grand: More than 90 inches long Ethan Allen loveseats range between 50 and 68 inches in length. Ethan Allen also offers sleeper sofas—sofas with a pullout mattress for overnight guests—in a range of sizes.
