The Savory Pillow top uses a posturized (more coils in the center third) 416 coil Tri-Zone innerspring. This innerspring provides correct anatomical support at a value price. Layers of Polyurethane foam, pre-compressed resin treated fiber, and lofted fiber provide firm underlying support. Then we quilt polyurethane foam and our Safeguard flame retardant fiber to the surface. Safeguard fiber is anti-microbial and is not chemically treated to achieve its flame retardant characteristics. 10 year non pro-rated warranty.
