How We Ranked the Top Crib Mattresses

Let’s talk about the good stuff you want to look for in a crib mattress so you can breathe a sigh of relief knowing you found the best option for your baby. 

Firmness– Crib mattresses should always be firm to provide the safest surface for babies to sleep. 

Hypoallergenic Layers– To put it simply, you want to minimize the possibility of an allergic response. This is usually the main reason for the price difference of a $100 crib mattress to a $300+ crib mattress. However, we did find one for under $150 to include on our list!

Price– Our top crib mattress picks are all just about $300, but they each offer different features. Everyone’s budget will be different, but it is something you should consider before shopping.

Size– Most standard crib mattresses are about 28” x 52”, but there can be small variations. You want to make sure that the mattress you choose fits snugly inside the crib for safety. 

Waterproof Cover– You want to be able to use the same mattress with your baby from the newborn stage through toddlerhood and maybe even afterward, so it is important to use a waterproof cover to keep it in good shape. I recommend looking for a mattress brand that makes their own covers so you can ensure a good fit.

Certifications– Ideally, you want to buy a mattress that has been third party tested and is Greengaurd GOLD Certified to ensure cleaner air for babies to breathe for a healthier environment.
