Sealy Baby Cozy Cool
Score: 81/100
Delta Children Twinkle Stars
Score: 81/100Rankings
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.
Delta Children's Miles 4-in-1 Convertible Crib mattress offers GREENGUARD Gold certification, waterproof hypoallergenic encasement, and a reversible 2-stage design for extended use. Availability is limited as the product is discontinued and the toddler guardrail must be purchased separately. Ideal for families seeking a certified, waterproof mattress that can grow with the child.
