The price of crib mattresses depends heavily on their quality; therefore, the better the quality, the higher the price. When you buy a quality mattress, you get comfort, safety, and longevity in exchange for your money which is definitely a good deal. Yes, you will pay a little more for a premium mattress, but you won’t need to visit the store any time soon looking for another one.

Other factors that may influence the price include the manufacturer’s reputation and the size and density of the crib mattress. With this in mind, the market price for crib mattresses is somewhere between $18 and $500. Obviously, you can find plenty of cheap crib mattresses, but remember that the safety and health of your angel is at stake. It is better to stay away for poorly built, ridiculously cheap crib mattresses because they might be potentially dangerous, and pick one which offers decent features and doesn’t break the bank. Yes, there are such mattresses available for purchase and we have selected 5 of them to feature on this review.


Crib mattresses vary depending on their make; foam, nature (organic or inorganic), and hypoallergenic capacity.
Some come with accessories and added features such as waterproof covers, mattress zipper bags, and dual-functional flip sides. Please note that low quality foam and innerspring crib mattresses have thin vinyl edgings and coverings that can tear, dry, and crack easily. If the covering is thicker, reinforced double or triple laminates, puncture-resistant, or has fine organic cotton, the longer the mattress will last.

Additionally, an innerspring crib mattress that has high-quality cushioning or has better-gauge steel will weigh more. The same applies to foam mattresses that are denser and have better quality foam. Everything that matters in a mattress is on the inside, buts cover also matters a lot. A waterproof crib mattress will serve your baby longer compared to mattresses that allows liquid and stain penetration.

Here is an overview of the features of crib mattress and brief description of each;

  • Foam Density — The denser the better. To assess the density of a mattress, place your hands on both sides of the mattress and press. The more dense mattresses will not allow your hands to sink far. The density spec can be checked from the manufacturers’ site.
  • Firmness — A crib mattress should not conform to your palm when you press it and should snap back immediately after you press. You do not want a mattress that conform with your baby’s head.
  • Convertibility — if you are planning to use the same mattress as your child develops, buy a dual-functional (dual-firmness convertible) crib mattresses. They are firmer on the infant’s size and cushier for toddlers on the flip side. We look at some excellent dual-firmness mattresses in this article.
  • Surface Cover — vinyl or fabric covers are normally used to cover the whole mattress. Fabric covers breathe more than vinyl ones. However, a multilayered vinyl cover will be more durable than a fabric cover. When purchasing a crib mattress, it is important to look for a three-ply cover that will add to its toughness and longevity.
  • Waterproof Covers — besides their make, it is also important to look at other cover qualities. A waterproof cover will protect your baby’s mattress from stains and liquids sipping through. The best thing about this option is that you can purchase a separate waterproof cover even if your crib mattress is not waterproof.
  • Antimicrobial Covers — do you need this new feature? Manufacturers say that such covers will slow down bacteria growth but will not prevent them.
  • Innerspring Layers — this feature applies to innerspring mattresses. If you are planning on purchasing this type of mattress, consider one with several layers. The more layers a mattress has, the better the quality.
  • Border Rods — a good innerspring crib mattress should have border line rods all around its perimeter. This will better support the mattress and prevent instances of sagging when the baby plays in the crib.
  • Steel Gauge and Coil Count — this also applies to innerspring mattresses. Look for a moderate to high coil count of about 135-150 and a steel gauge of 15.5 and below. In the same case, you should consider the quality of an insulator pad (a thick pad on top of a steel coil that prevents it from poking outside). A good insulator pad should be able to hold up for long.
Construction and Design

When choosing a crib mattress, there are a number of structural factors that you are supposed to consider and the first one is firmness. A baby’s mattress should be firm enough to avoid suffocation. As we just mentioned, a soft crib mattress may take the shape of to the baby’s face or head and increase the chances of suffocation. It shouldn’t be too stiff either because your baby spends over 18 hours a day sleeping, so a severely stiff mattress wouldn’t be comfortable enough. There should be proper balance in firmness for safety and comfort. The mattress’s cover also matters a lot. Remember that at this stage, babies like to spill the juice or milk a lot, so a waterproof crib mattress would be ideal for durability. Other construction and design consideration factors include functionality (dual-sided or not), weight, material type (foam or cotton), and product dimension (in terms of inches).

There are two types of crib mattresses; foam and innerspring. Either type is fine as long as you focus on a good-quality. The better the quality, the higher the safety and comfort your infant or toddler will enjoy.

  • Foam Crib Mattresses — these types are normally made using polyurethane and the covers might differ. They might be antimicrobial, organic, waterproof etc.
  • Innerspring Crib Mattresses — these types are made with several layers of better-gauge steel as well as a layer of cushioning. More layers and better cushioning add to the safety and comfort of your baby.

Performance and Ease of Use

An infant/toddler mattress should fit the crib to allow the sheets to remain static throughout your baby’s sleep hours. Additionally, a good crib mattress should be lightweight to allow for easy shifting and crib cleaning from time to time. Dual-functional crib mattresses are cost effective; they can be used both when the baby is an infant and a toddler. Ideally, you should look for a crib mattress that features a more sophisticated design. For example, one which comes with a side that is firm enough to support the infant and allow for a cozy nap, and another side that is comfortable enough to support the increased and continually increasing weight of a toddler.

Crib Mattress FAQs

How big is a crib mattress?
A standard crib mattress measures 27 ¼ inches by 51 ¼ inches with a thickness that isn’t more than 6 inches. If you have a giant crib, then you can buy a larger mattress.
How to choose a crib mattress?
You can choose a crib mattress by looking at its quality and ability to provide comfort to your child. Its features, design, and construction should be just right. The features you should look at include foam density, foam firmness, convertibility, cover, waterproof covers, antimicrobial covers, innerspring layers, border rods, and steel gauge. Notably, a crib mattress should be available at an affordable price for you to acquire it.
How to elevate crib mattresses?
To elevate a crib mattress, you could place a rolled towel or blanket under it. Usually, the material you put under the crib should be 3 to 6 inches thick to give you a proper incline. Alternatively, you may use a crib wedge under the mattress to get the right inclination levels without the bed budging or becoming unstable.
