Sealy Baby Cozy Cool
Score: 81/100
Serta Perfect Start
Score: 80/100Rankings
The Sealy Cozy Cool Hybrid provides a 2-stage mattress with 204 coils and a cool-gel foam side, wrapped in a waterproof breathable cover. Its heavier weight and lack of GREENGUARD certification are notable compromises. It fits parents who want hybrid support and temperature regulation.
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.
