Sealy makes the Posturepedic line of mattresses featuring a combination of foam top with coil and gel centers, while Therapedic, a different manufacturer, makes a variety of mattresses under many brand names with different features and materials. Therapedic mattresses may include foam, coil or gel components depending on the brand.
Therapedic mattress brands include names such as Kathy Ireland, Memory Touch and Agility, among many others. Each of these brands features different mattress technology, from foam tops that "remember" body shape, as in the Memory Touch product, to more conventional inner spring mattresses, as in the Kathy Ireland brand. Therapedic started out as a local New Jersey mattress company and is now an international manufacturer with locations around the world.
Sealy Posturepedic mattresses all feature some combination of the company's CoreSupport center, inner-spring or coil component, and foam top. Sealy Posturepedic mattresses come in three series, the Posturepedic Series, the Posturepedic Plus Series and the Posturepedic Premier Hybrid Series, with added features in the Plus and Premier lines. Sealy traces its history back to Sealy, Texas in 1881, when Daniel Haynes made a cotton-filled mattress. As of April 2015, Sealy manufactures its mattresses at 25 facilities in the United States.
