Add breathable, waterproof protection to any crib mattress. The unique spacer fabric promotes airflow to help regulate temperature and reduce suffocation risk, according to independent testing. A quiet, waterproof lining shields against leaks without blocking airflow, helping maintain a healthy, dry sleep environment. Unlike plastic pads, this one stays silent as baby moves, with no crinkly noise to interrupt sleep. The pad adds a safe sleep layer at home, on the go, or during potty training. When messes happen, just pull it off and toss it in the wash.Complete the setup: Pair with the Newton Essential Crib Mattress for breathable, waterproof protection.GREENGUARD Gold Certified.
