Offering you the perfect blend of support and comfort, the Stearns and Foster Estate Soft Mattress features IntelliCoil® innersprings and premium memory foam for a relaxing feel you'll enjoy night after night. The sturdy, tight-stitched top gives you a more responsive sleep experience. Its stretch-knit fabric is made from a sustainably sourced Tencel™, a fiber also used in athletic wear. This fabric wicks moisture away from the body, keeping you comfortable as you sleep. The ventilated coils and external air vents help keep heat from building up by pulling warm air away from your body, promoting cool, deep sleep all night long. Your only regret may be that you didn't get a Stearns and Foster Estate Soft Mattress sooner.
