Temperature management bedding systems
Temperature management bedding systems for mattresses and quilt panels generally include a trilayer of active components including a phase change material applied to a top surface of a flexible substrate thereof, a fire retardant layer underlying the flexible substrate including hydrophilic rayon fibers treated with ammonium polyphosphate; and a vertically oriented fiber batting layer underlying the first retardant layer including an elastomeric binder. The temperature management bedding systems provide heat control and mass transfer of moisture from the bedding surface.
