Sealy Baby Posturepedic Grace 2-Stage Infant and Toddler Crib Mattresses provide one-of-a-kind targeted support with the Posturepedic® Advanced Zone Support System. The targeted areas create support and comfort where infants and toddlers need it most. Center zones target the sweet spot, where infants are placed in their cribs, offering enhanced firmness in the middle of the mattress. Comfy layers are added to the toddler side plus extra head and foot support for active toddlers. The Sealy Baby Posturepedic Grace Hybrid model is upgraded as a coil and foam “hybrid” similar to adult mattresses. This offers extra comfort and pressure-relieving feature like the hypoallergenic soy-enhanced memory foam cushioning that safely senses and responds to your child’s movement for contouring comfort. Coils and foam are tested for lasting durability. Baby Posturepedic 2-stage models grow with your child with two levels of firmness, targeted support throughout, and fit all standard-size cribs and toddler beds. Highly durable cotton fabric surfaces and tightly woven fabrics help create an easy-clean surface. The fabric is breathable on the baby’s skin while the waterproof barrier underneath protects against mold, mildew, and odors inside the baby’s mattress. The advanced Support system also features a high coil count with 204 durable coils, 10-strength pillars, and steel edge guards for a lifetime of use.
