Score: 81/100Rankings
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.
The Sealy Baby OptiCool offers a lightweight, dual-sided foam design with a cooling gel toddler surface and a waterproof breathable cotton cover. Its 60-lb weight limit and all-foam construction may limit durability for larger toddlers. Best suited for families prioritizing portability and GREENGUARD-certified comfort.
