Wolf Corporation has been creating Sweet Dreams since 1873! We are the oldest mattress manufacturer in the USA under continuous family ownership. In addition, Wolf Corporation is the oldest Serta licensee, proud to say we are the sole manufacturer of Serta Futon Mattresses! Serta Futon Mattresses feature Cottonique. Cottonique combines selected grades of cotton with polyester fibers for a unique, durable upholstery blend that outperforms and outlasts traditional cotton batting. As a result Serta futons are more resilient, more comfortable and yet surprisingly light. The Serta Willow futon mattress is a high quality foam and cotton futon with both finger foam and a 1" foam core made out of Serta's proprietary gel foam surrounded by layers of Wolf's cotton blend. It is 8" thick and provides firm support. It has a five year warranty. Machine lace tufts and true box casing construction complete the Willow. This Willow futon mattress is covered in a cedar green microfiber casing and is queen size, 60" x 80". All Serta Futon mattresses are compressed, rolled and boxed which makes for ease in shipping and installation.
