Newton Baby Crib Mattress Cover - Best Overall
Newton Baby's mattress cover is engineered with the same breathability-first philosophy as their full mattress line. The cover uses a breathable TPU waterproof barrier that allows airflow while blocking all liquids - even under sustained pressure. It fits snugly on standard crib mattresses, makes no noise when the baby moves, and washes easily. The quiet, breathable waterproofing combined with a soft quilted top makes this the best single cover for newborns through toddlers.
Naturepedic Organic Cotton Crib Mattress Cover - Best Certified Organic
Naturepedic's cover uses a GOTS-certified organic cotton top layer with a food-grade polyethylene waterproof barrier - no PVC, no vinyl, and no phthalates. It's the cover to reach for when parents are committed to a fully certified-organic sleep environment. The elastic skirt fits tightly over standard mattresses and holds through machine washing without stretching out. Paired with a Naturepedic mattress, it creates the most comprehensively certified sleep surface on the market.
Graco 2-Pack Waterproof Fitted Crib Sheet Cover - Best Value Multi-Pack
The practical wisdom of buying two mattress covers so you always have a clean one ready is baked into this Graco 2-pack. Each cover features a jersey-knit top layer that's soft against skin, a quiet (not crinkly) waterproof barrier, and a deep elastic skirt for secure fit. Having two identical covers in rotation makes nighttime changes faster and less stressful - a feature that matters more at 3 AM than any premium certification.
Safety 1st Peaceful Slumber Waterproof Cover - Best Budget Pick
Safety 1st's cover earns its place on this list by being genuinely quiet - a problem that plagues many cheap waterproof covers that crinkle loudly every time a baby moves and can disrupt light sleep. The Peaceful Slumber addresses this with a cotton blend top that absorbs the noise. Waterproofing performance is solid at its price tier, and the elastic skirt secures reliably to standard crib mattresses. A confident budget pick from a trustworthy brand.
Moonlight Slumber Mattress Cover - Best Soft-Top Premium Feel
Moonlight Slumber's cover prioritizes tactile quality alongside waterproofing - the quilted cotton-blend top layer is noticeably softer than standard waterproof covers and adds a subtle cushioned feel without compromising mattress firmness. The waterproof barrier is quiet and effective, and the construction is robust enough to maintain fit and performance after repeated washing. A great pick for parents who want the nicest feel for the dollar above Safety 1st's baseline.
Before you buy
Waterproof Barrier Material
TPU and food-grade polyethylene are the safest options; avoid vinyl (PVC) covers, which can off-gas plasticizers - especially problematic in a fully enclosed crib environment. - **Noise Level:** A crinkly waterproof barrier disrupts infant sleep every time the baby moves. Test this by pressing and shifting the cover material - it should be quiet and soft-feeling, not stiff. - **Fit Security:** Deep elastic skirts (minimum 9 inches) that hug the full perimeter of the mattress are critical - a cover that shifts exposes the mattress edge and can create a safety gap between cover and crib frame. - **Wash Durability:** The waterproof laminate is the first thing to fail on budget covers after repeated washing. Choose covers with warranty information or verified reviews confirming long-term waterproof performance after 50+ washes.
The wrap-up
Newton Baby's cover is the safest and most breathable option for parents of newborns, while Naturepedic is the right choice for a fully certified-organic sleep setup. For practical households where value and convenience drive the decision, the Graco 2-pack is the smartest purchase on this list - two covers at a combined price lower than the premium single options, ready for the round-the-clock rotation that early par
Quick answers
A crib mattress cover (or protector) is typically a waterproof encasement or fitted sheet-style protector that sits directly on the mattress surface to guard against liquids and allergens. A mattress pad adds a thin layer of cushioning on top of the mattress for comfort. For infants, a thin waterproof cover is preferred over a thick pad, as it preserves the firm sleep surface the AAP recommends.
Some waterproof covers - particularly those using vinyl or thick polyurethane - can reduce airflow and trap heat, which is a safety concern for infants. The best covers use breathable TPU (thermoplastic polyurethane) laminate or similar materials that block liquids while maintaining adequate airflow. Newton Baby and Naturepedic covers are specifically designed to balance waterproofing with breathability at the highest standard.
Most crib mattress covers are machine washable on a gentle or normal cycle in cold or warm water. Avoid hot water and high heat drying, which can degrade the waterproof laminate layer over time and cause it to crack or peel. Tumble dry on low or air dry flat. Always check the care label - some covers with organic cotton tops require more specific washing instructions to preserve the certification.
