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 Ash futon is constructed with 4" of premium cotton/poly fiber fill for natural support. It has a premium cotton black color duck casing and is approximately 4" high. It is a queen size, 60" x 80". It has a 1 year warranty. All Serta Futon mattresses are compressed, rolled and boxed which makes for ease in shipping and installation.
