Here, the best crib mattresses for a good night’s sleep.

Final Verdict

For a breathable, firm, and cooling option, we love the Newton Baby Crib Mattress and Toddler Bed Best. All of the components are machine-washable for great sleep for your baby and an easy clean-up process for you. For a more budget-friendly pick, we recommend the Graco Foam Crib and Toddler Mattress. This comfortable foam option includes a waterproof outer cover, free from chemicals and allergens.


Avoid ordering a mattress just for it to not fit in your child’s crib by double checking the size. A standard crib is about 28 by 52 inches. You want your mattress to fit snugly in your crib without any gaps. This avoids your baby from sinking into the mattress or slipping to one size and potentially getting stuck, says Lindsay Albutt, RN. “These are all recommendations supported by the American Academy of Pediatrics,” she says.

Mini or portable cribs will require a different size mattress. Mini cribs are usually only 24 by 38 inches, so be sure the mattress you are purchasing will fit in your desired space. This is the first step to building a safe and comfortable space for your baby to sleep.


Crib mattresses come in a variety of materials, from foam and cotton to wool and polyester. Perhaps more important than the actual material is the construction of said material. You want to make sure the materials of the crib you purchase are non-toxic and free of chemicals—this prevents your child from breathing in toxins when sleeping. Look for words such as “organic,” “non-toxic,” and “hypoallergenic” when shopping. This guarantees your mattress will not irritate your child or trigger any allergies.

The material of a mattress can also affect how hot or cold it feels throughout the night. If your baby runs warm, consider buying a cooling mattress that ensures they won’t overheat.


Albutt shares that placing babies on their back on a firm, flat sleeping surface can reduce the risk of Sudden Unexpected Infant Death. According to her research, out of 3,400 deaths that occur every year from SUIDS, 72 percent occur in unsafe sleeping environments. Thus, it becomes increasingly important to take small measures to prevent any harm to your child at nighttime.

“Firmness ensures that when babies inevitably roll over, they won’t suffocate,” Mommywise founder Natalie Nevares explains, and it does not have to sacrifice comfort. “If I wouldn’t want to sleep on the mattress, I don’t want my baby sleeping on it,” she adds.


Nevares says along with firmness, breathability is most important to her when shopping for a crib mattress. A breathable mattress ensures that if a baby flips over onto their stomach, they can still breathe, and most mattresses are made with this in mind. Different fabrics can be more breathable than others, but looking for products that pride themselves on being lightweight and breathable is always a good idea.

“Avoid anything with pillow tops or comfort tops as they can lead to a sleeping area that is too soft,” says Elizabeth King, founder and CEO of Sleep Baby Consulting. “These soft spaces allow baby’s face to get trapped and can inhibit breathing,” she shares.


While not always pivotal for ensuring safety or comfort, many crib mattresses boast environmentally conscious materials and practices that can be appealing to a consumer. “When choosing the right mattress for your baby, I recommend looking for a firm mattress that is Greenguard Gold Certified. This certification ensures that the interior of the mattress is low in chemical emissions,” says certified sleep consultant Kaley Medina. This means safer materials for your baby and the earth.


In case of accidents, waterproof crib mattresses are easy to wipe down or throw in the washing machine for a quick turnaround. Some options on this list come with non-removable waterproof covers that are stitched together to ensure no liquid gets through. Others have removable options that you can wash, swap, and reuse. For any option on this list, you can consider adding a waterproof cover on top to make the cleaning process a little bit easier.

One thing to note—waterproof covers can often be loud or crinkly. They are often made from plastic or vinyl that may not the most comfortable to sleep on. If not already included on the mattress, look into the materials of a waterproof cover before purchasing. While a brand may boast an organic, non-toxic mattress, these claims may not carry over to the waterproof cover. You don’t want to ruin all of the hard work you did in searching for a non-toxic, organic, allergen-free mattress just by covering it up with something not as clean or safe.


  • Most crib mattresses are made with cleanliness in mind. Many options on this list include a mattress and a cover that can easily be thrown in the washing machine weekly or immediately after spills or accidents. Others include waterproof covers that easily wipe down to avoid stains and liquid seeping through. Look into the care instructions before taking the plunge to prepare for inevitable messes.

  • Medina and Navares agree that the crib and mattress do not have the biggest impact on your child’s sleep. Still, creating a safe, comfortable space for your baby is a great way to start. “The single most important thing you can do to get your child sleeping well is teaching how to fall asleep independently, without the assistance of any sleep associations or sleep props,” says Medina. Ensuring that your child feels good in their crib and all of the safety precautions are taken only aids in this process.

    Nevares adds, “Sleep and development go hand in hand. Once they’re getting great-quality sleep, then their development skyrockets.” Thus, anything a parent can do to improve a baby’s sleep, including finding the perfect mattress, contributes to your baby’s development.

  • In a crib, babies need a good flat mattress and a fitted sheet. This sheet should be as tight on the mattress as possible to prevent the baby from suffocating if they roll over on their stomach. “The mattress with the fitted sheet are the only two items that should be in your baby’s crib…no mobiles, blankets, stuffed animals, toys, bumpers, etc., for safest sleep,” says Medina. Because an infant requires so few products to sleep, it becomes important to ensure these few products are as high-quality and safe as possible.
