Abstract
A fire-retardant mattress having at least one sleeping side is disclosed that has an inner support compartment with a generally parallelepiped shape with a top side opposite the sleeping side and a fire-containing compartment covering the top side of the inner support compartment and located between the sleeping side and the inner support compartment. The fire-containing compartment includes a first fire-resistant layer consisting essentially of natural fibers, the first fire-resistant layer being in direct contact with the top side of the inner support compartment, a second fire-resistant layer consisting essentially of natural fibers, the second fire-resistant layer located separate from the first self supporting layer of fire-resistant material, and a plurality of combustible cushioning layers positioned between the first and second fire-resistant layers. The first and second fire-resistant layers form a compartment around the plurality of combustible cushioning layers to delay combustion of the fire-retardant mattress from fully catching fire.
