The Sealy Posturepedic® level offers superior support that's built to last. The impressive Posturepedic® support system features our exclusive PrecisionFit™ Coils, arranged right where you need them to help maintain natural body alignment and reduce nagging bed aches. A coil edge provides a solid seating surface that's built to last. Each of the 736 coils in the Sealy Posturepedic® level (for a queen-size mattress) is individually encased to reduce motion transfer, helping you feel less movement from your partner through the night. Plus, Surface-Guard Technology™ kills bacteria on the surface of the mattress, protecting it from common allergens which can lead to a better night's sleep.
