Sealy Baby Posturepedic Grace Hybrid
Score: 78/100
Serta Perfect Start
Score: 80/100Rankings

The Serta Perfect Start Two-Stage Crib Mattress combines a breathable, waterproof cover with a recycled-fiber core and a convertible infant-to-toddler design. At 5-inch thickness it may feel less plush than thicker alternatives, and its weight is higher than mini options. Ideal for families using standard full-size cribs who value eco-friendly materials and a long warranty.

The Sealy Baby Posturepedic Grace Hybrid 2-Stage Crib Mattress combines a soy-enhanced foam layer with 204 innerspring coils, delivering firm infant support and cushioned toddler comfort. Its hybrid construction and certifications add safety but the mattress is heavier than foam-only options. Ideal for parents seeking a durable, certified hybrid mattress that grows with their child.
