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 Liberty futon is constructed with 6" of premium cotton/poly fiber fill for natural support. It is approximately 6" high. It has a 1 year warranty. All Serta Futon mattresses are compressed, rolled and boxed which makes for ease in shipping and installation. Proud to say Made in the USA!
