The crib is the best place for your baby to sleep. It is accessible to the parent yet gives the infant their own space to sleep in. If you use the crib regularly for your baby’s naps, ensure that you choose the ideal crib mattress to make nap or sleep time relaxing and soothing.
In this MomJunction article, we give you a list of 15 best and crib mattresses for your precious little one. Before that, some information on the types and sizes of crib mattresses and how to pick the right one for your baby’s crib.
Does Your Baby Need A Crib Mattress?
Yes. The American Academy of Pediatrics recommends the use of firm sleeping mattress for your baby’s crib (1). Your baby only needs a mattress and a fitted cover/sheet in their crib. There should not be any toys, pillows, towels, or other items that could pose the risk of entrapment, suffocation or strangulation.
Do Crib Mattresses Vary In Dimensions?
Yes. Crib mattresses vary in sizes to suit cribs of different sizes. The two common types of cribs include:
- Full-size crib: Interior/Base width of 28 ± 5/8 inches (71 ± 1.6 centimeters) and length of 52 3/8 ± 5/8 inches (133 ± 1.6 centimeters).
- Mini/portable crib: There is no standardized size for it, but product regulatory bodies state that its interior width should be less than 25 3/8 inches (64.3cm) and length should be less than 49 3/4 inches (126.3cm). Most manufacturers of mini/portable crib stick to a width of 24 inches (60.96cm) and a length of 38 inches (96.52cm).
These dimensions are as recommended by the US Consumer Product Safety Commission for standardized cribs (2) (3). However, custom-made cribs may vary slightly in size, so be sure to check the crib’s interior/base dimensions before buying a mattress for a snug fit.

Are There Different Types Of Crib Mattress?
Yes. The following are the three types of crib mattresses:
- Coil mattress: Coil mattresses have steel springs/coils and quite likely an outer steel frame for support. The coils are topped with cushioning material such as cotton or foam. The more the number of coils, the more comfortable a coil mattress gets. Coil mattresses tend to be expensive, but are also more likely to retain their shape for longer.
- Foam mattress: Simple mattresses with an external fabric cover that is tightly stitched over polyester foam. Foam mattresses are lightweight and soft to touch but may lose their firmness over a period since there is no internal metal coil for support. When picking foam mattress, choose the one that has the highest density of foam since it will stay firmer for longer.
- Two-sided mattress: Also called double-sided mattress or 2-in-1 mattress, which usually have foams of different firmness on either side. It is firm on one side and softer on the other. If you want a one-time purchase for both infant and toddler years, then this mattress is for you.
It is essential to know the type of mattress and also how to pick the right one for your baby.
How To Choose A Crib Mattress?
Keep in mind the following criteria when exploring crib mattresses for your baby:
- Right size for your crib: The mattress should fit perfectly into the crib base: from edge to edge. A gap between the mattress and the side walls increases the risk of a baby’s face getting stuck in the gap or them falling into it. Always check the crib dimensions before buying a mattress for it.
- Mattress sheet: Some mattresses may come with a sheet/cover. Other mattresses may not require a bed sheet since the external fabric doubles as a cover. It is always good to pick mattresses that you can use without bed sheets to eliminate the risk of suffocation and keep your baby safe.
- Waterproofing: If your baby sleeps without diapers, then waterproof or water resistant mattresses are the ideal choice. Waterproof mattresses are covered with a layer of plastic or waterproof fabric and do not permeate water within. Water resistant mattresses prevent small quantities of fluid from passing through.
- Do not buy second-hand: Mattresses are intimate products. Babies may poop or puke on it, which can make the mattress susceptible to bacterial and fungal growth. You may not know whether the previous owner would have taken adequate care while cleaning the mattress. A second-hand mattress can expose your baby to pathogens. Therefore, it is best to go first-hand when buying a crib mattress.
You can also choose mattresses made of organic material or ones that may be free of chemicals in any form. There is no scientific evidence to suggest that such mattresses are better than the usual ones. Nevertheless, parents can pick these mattresses after checking the material quality.

Crib Mattress Safety Guidelines
- Snug fit: A crib mattress should always fit snugly within the crib base. Even the slightest gap between the mattress and crib wall/railing can pose a suffocation hazard. Consumer products experts state that there should be a very minimal gap between the sides of the crib and the edge of the mattress (4). If your crib comes with a mattress explicitly designed for it, avoid purchasing a separate mattress.
- Mattress cover should go over the side: If the mattress cover does not envelope the mattress and only covers the top, then find a cover that it goes all the way over the edge of, or around the mattress. If you intend to use a blanket or a warm sheet during winter, then tuck the blanket over the mattress like a cover, and place the baby on top.
- Regular cleaning: Keep the mattress clean even if your baby does not soil it. Most manufacturers have machine washable covers. If your mattress does not have one, then use a sponge soaked in a baby-safe disinfectant liquid to clean the mattress.
- Turn mattress when the baby becomes toddler: Switch to the toddler side of the mattress once your baby is old enough to sleep on the softer side. Infant-safety experts recommend switching the baby to a toddler bed at the age of 18 months (5).
