10 Best Crib Mattresses 2026 in the United States

The Graco Premium Crib & Toddler Mattress positions itself as a solid choice for parents looking for a safe and comfortable sleeping surface for their infants and toddlers. One of its most notable strengths is its certifications: it’s GREENGUARD Gold Certified, which means it helps ensure cleaner indoor air quality, and CertiPUR-US Certified for low emissions, making it a favorable option for health-conscious families. The mattress is designed to fit standard full-size cribs and toddler beds, so it should meet the size requirements of most cribs without issues.

In terms of comfort, the high-density foam provides a firm yet supportive surface that is essential for infant safety and proper spine development. Its waterproof outer cover is a big plus, as it keeps the mattress clean and dry from any spills or leaks, and the machine-washable feature makes maintenance easy for busy parents.

The mattress weighs in at a manageable 12-15 pounds, making it easy to handle, but it’s still advisable to ensure it’s the right fit for your crib. For parents looking for a reliable, safe, and easy-to-care-for crib mattress, the Graco Premium Crib & Toddler Mattress is a commendable option.

The Newton Baby Waterproof Crib Mattress is designed with safety and convenience in mind, standing out mainly for its unique breathable Wovenaire core. This special material helps reduce the risk of suffocation and overheating, which is a big plus for parents prioritizing their baby's safety. The mattress is firm, which is recommended for infant sleep to support proper development and reduce risks. Sized at the standard crib dimensions (52" x 28" x 5.5"), it fits most cribs and even transitions to a toddler bed with its 2-stage design, meaning you get longer use from the same mattress.

One of its biggest strengths is its waterproof feature on the toddler side, protecting against leaks and accidents while keeping the mattress clean. Both the removable cover and the core itself are washable, making it easier to maintain a hygienic sleeping environment, which is not always common in crib mattresses. The mattress weighs 15 pounds, which is manageable for moving or cleaning but feels sturdy enough to stay in place. It's also Greenguard Gold Certified, meaning it meets high safety standards for low chemical emissions, which helps keep your baby's air quality healthy.

The mattress is relatively thin at 5.5 inches, which might feel less cushioned compared to thicker options. While the breathability is fantastic, some parents who prefer traditional foam or innerspring mattresses might find the feel different or less plush. Its price point tends to be higher than average, reflecting its advanced materials and features. This crib mattress is ideal for parents seeking a highly breathable, washable, and safe mattress with waterproof protection. It’s especially suited for babies with allergies or sensitive skin and those who want a mattress that grows with their child from infant to toddler stages.

The Naturepedic Organic Crib Mattress is a solid choice for parents seeking a safe and healthy sleeping surface for their baby and toddler. It features a two-stage design with a firmer side for infants and a slightly softer medium-firm side for toddlers, providing suitable support as your child grows. Made from 100% GOTS-certified organic cotton and pocketed coils, it meets strict safety standards while being non-toxic and low in chemical emissions.

Breathability is another strong point, thanks to its organic cotton cover and a breathable core that helps regulate temperature and reduce overheating. The patented waterproof coating on the fabric adds convenience by allowing easy cleaning with just soap and water, protecting against spills and accidents. In terms of size, it fits most standard cribs snugly with dimensions around 27 by 51 inches and is about 6 inches thick. Weighing roughly 14 pounds, it is relatively lightweight compared to typical coil mattresses, making it easier to handle during sheet changes.

Some parents may prefer an even firmer feel for newborns, depending on personal comfort preferences. The price point may be higher than non-organic options, which is worth considering if budget is tight. This mattress is especially suited for parents who prioritize organic materials, certified safety, and a versatile mattress that grows with their child.
