Experience the convenience of a mattress in a box with this hybrid model that delivers an ideal medium-firm feel, perfectly balancing supportive pressure relief and spinal alignment. The tight top design provides a uniform, non-shifting sleep surface layered with soft, skin-friendly knit fabric and contouring foam. At its core, individually pocketed coils work independently to eliminate motion transfer, ensuring an undisturbed sleep. Specially reinforced edges create a sturdy perimeter, preventing sagging and making getting in and out of bed easier. Engineered for lasting durability, this mattress meets all applicable federal flammability standards (CPSC 16 CFR 1632 & 1633) and is an excellent choice for back and stomach sleepers.
