The Mary Twin Sleeper Sofa from the Washable Wonders offers a soft tailored style. Soft tailoring is a type of upholstery in which the end result is a much more casual piece. The skirts are not lined, and will drape naturally, sometimes that can mean that they are uneven. Welt lines can be wavy, and you will find comfort wrinkles through out the piece. This slipcover style Sleeper Sofa features track arms, one square boxed back, one padded seat cushion and a bottom skirt. It is adorned with beautiful welting details.
