13 Best Crib Mattresses for Babies

When a baby is born, it spends up to as many as 17 hours sleeping every day. According to the National Sleep Foundation, newborns up to 3-month-olds need at least 14-17 hours of sleep a day – it sounds like a dream, doesn’t it? Thus, it’s important to buy a comfortable and safe crib mattress for your baby. But shopping for the best crib mattress for babies or a toddler isn’t the same as shopping for an adult-size bed.

How To Choose The Best Crib Mattress for Babies?


One of the most important factors to consider when it comes to buying a toddler and baby crib mattress is firmness. Usually, baby mattresses are firmer than adult mattresses as they support their growing bones and keep them safe while they sleep. If that wasn’t enough, firm mattresses also help reduce the risk of SIDS (sudden infant death syndrome).

Fit and size

There’s no doubt that the mattress fit and size are other important factors. According to the Consumer Product Safety Commission, full-size crib mattresses must measure 51.24 inches long and 27.25 inches wide. What’s more, the mattress should fit snugly against the frame of the crib, and parents shouldn’t be able to fit more than two fingers between the crib and the mattress. This prevents the baby from slipping in between or sinking into the mattress and potentially getting stuck. Also, remember that portable or mini cribs will require a different-sized mattress.


Crib mattresses need to either have polyethylene or a vinyl surface that makes them waterproof and resistant to mold. Are you choosing a fabric option? Always add a waterproof cover. Since some parents prefer mattresses made from organic and natural materials to avoid chemicals, that also works.


Finally, you need to look at the breathability of the crib mattress, which ensures that babies can still breathe if and when they flip over onto their stomachs. While different fabrics are more breathable than others, looking for products that specifically market themselves as breathable and lightweight is a good idea.

What type of mattress is best for babies?

Pick foam crib mattresses to help prevent SIDS (Sudden Infant Death Syndrome) and suffocation, which even the AAP recommends (American Academy of Pediatrics).

Do babies sleep better on a crib mattress?

Yes, as they’re much more comfortable than traditional mattresses.

How thick should my baby’s mattress be?

According to the Consumer Products Safety Commission, the crib mattress should be no more than 6 inches thick.
