For peace of mind during the night, we recommend the Newton Baby Crib Mattress as our best overall pick.

Also, the entire mattress is washable, from the removable cover to the mattress. Constructed without foam, glue, latex, or springs, parents won't have to worry about allergens when their baby sleeps either. Made from recycled materials and GreenGuard Certified, which guarantees this product has low chemical emissions, Newton Baby proves to be an eco-conscious company that consumers can feel good buying from.

Satisfied parents love the breathability and cooling features of this mattress, so they don't have to worry about their baby overheating during the night. In terms of safety, parents feel confident letting their child sleep on their stomach on this pick. While expensive, the Newton Baby mattress easily grows with your child from an infant to toddler.

One thing to note, some users reported a strong smell of plastic upon opening. Luckily, this seems to go away after the first wash.

Best Splurge

Avocado Organic Crib Mattress

Ensure there are no harmful chemicals or toxins in your child's mattress by picking an organic option, like this one from Avocado. Its blend of latex, wool, and cotton ensures your baby has a soft and comfortable sleeping place while being breathable and soothing.

We love that they use GOLS organic-certified latex and GOTS organic-certified wool. These materials last longer and feel sturdier than competitor options, but they feel heavier, resulting in a 28-pound mattress. Still, the organic materials and dual sides for babies and toddlers make this pick worth the heavy weight and price tag.

_{Dimensions: ‎52 x 28 x 6 inch | Materials: GOLS organic certified Dunlop latex, GOTS organic certified cotton and wool | Thickness: 6 inches | Cover?: Yes | Warranty: 25 years | Certifications: GreenGuard Gold, OEKO-TEX®: Class 1}

Best Convertible

Moonlight Slumber Little Dreamer Crib Mattress

View On Amazon View On Bambibaby.com

As babies get older, they transition to a softer crib mattress that keeps them comfortable while sleeping. Instead of buying two mattresses, consider one with two sides designed for two stages of your child's life, like this one from Moonlight Slumber. One side contains extra-firm plant-based foam ideal for infants. The other boasts soft and plush foam that toddlers can melt into.

The medical-grade stretch knit fabric holds up well over time while resisting water, odors, bed bugs, and dust mites. Parents can feel good about this PVC-free, phthalate- and lead-free, non-toxic, antimony-free, and vinyl-free mattress that won't irritate your baby's skin or allergies while sleeping. It also comes with a waterproof cover, which proves helpful in case of accidents.

Finding a waterproof crib mattress or cover is pivotal for keeping a clean sleeping space for your baby. It makes it much easier to wash and clean up spills or accidents without fear of staining or damage. We love this pick from Sealy, which features an antimicrobial and odor-resistant waterproof cover with lock-stitched binding, so nothing can seep through.

The heat-tempered interlocking steel coils in this innerspring option ensure your baby stays cool and content throughout the night. Additionally, the all-around secure edge heavy gauge steel border rods keep them from sinking into one side or getting stuck anywhere on their bed. The cover can make some noise throughout the night, but the cleanliness it provides makes it worth the risk.
