The Estate 2012 Sheila Luxury Firm Mattress is part of the Stearns and Foster Collection. This Firm mattress is designed to give you stiffer support at the surface, which is great for stomach sleepers, with a hint of softness for comfort. High density foam layers enhance the durability of the mattress, with a layer of memory foam that provides conforming comfort as it shapes to your body. The Intellicoil iD titanium innerspring system features a unique two-in-one coil design which is individually wrapped to give you deep-down support and comfort. A foam encased edge system creates a firmer, more substantial sitting and sleeping edge. This mattress also includes an exclusive Indulge Quilt with tension-relieving foams that will cradle you in complete comfort for a luxurious night's sleep. Box spring not included.
