How We Chose the Best Crib Mattress for 2020

– Our Ranking Methodology –

Obviously, we can’t test mattresses designed for babies the same way we test other types of beds. Also, we can’t ask infants if they had a good night’s sleep. Still, there are a few criteria that can help us make a sound decision if a mattress is a good pick. So we focussed on the following:

Quality Materials

Quality has definitely been one of our primary concerns. First, the best mattress for kids should be made of high-quality materials in order to offer a high level of comfort for your cute bundle of joy. Therefore, in the case of innerspring mattresses, we looked for those with thicker coils (lower gauge). And in the case of foam beds, we picked the ones constructed with a foam of higher density.

Besides ensuring great comfort, quality materials promise longevity. Considering that kids typically sleep in the crib till the age of three, you don’t want a cheap mattress that will show signs of wear and tear after only one year of use. Instead, the best baby crib mattress should provide exceptional support as long as your kid is sleeping in a crib.

Certificates

Another key factor for choosing a mattress for a baby’s crib is its material composition. More precisely, it’s essential that they meet strict standards regarding their content of VOCs (volatile organic compounds), heavy metals, and other harmful substances. That’s why we looked for the following certificates, which prove that a mattress isn’t harmful to your baby’s health or environment. And no crib mattress, not just the best rated crib mattress, should have adverse effects on a kid’s health.

  • The CertiPUR-US certificate proves that the polyurethane foams used in the mattress don’t contain heavy metals (such as lead and mercury), harmful flame retardants, phthalates, or other substances that can have adverse effects on our health. Additionally, these materials have low VOC emissions.
  • The Greenguard Gold certificate also shows that the materials used have low VOC emissions.
  • STANDARD 100 by OEKO-TEX® is an international label proving that the textiles are safe for human health.
  • The Global Organic Textile Standard (GOTS) certifies that a mattress is made of a minimum of 70% organic fibers. So if you’re shopping for the best organic crib mattress, you should look for this label.

Warranty

It’s always better when a product comes with a warranty. It gives you peace of mind that a mattress is made of high-quality materials and that it will be durable. In addition, it shows that the manufacturer is confident about its products and that it will cover any damage. However, it’s not enough that a warranty covers a long period—you need to carefully check the terms and conditions, which customers have emphasized in many crib mattress reviews.

Price

A higher price typically means better quality, but this doesn’t mean you should spend a fortune on a mattress. In general, you can get a good crib mattress for $90 to $200, and most mattresses on our list fall into this price range.

Our goal was to only present you with models that offer good value for the money.

How to Pick the Best Crib Mattress for Your Baby

– Buyer’s Guide –

According to the National Sleep Foundation, newborns need between 14 and 17 hours of sleep a day. Infants sleep only a couple of hours less, and toddlers still need at least 11 hours of sleep to grow and develop healthily.

Therefore, it’s crucial that their sleeping surface provides them with adequate support and great comfort. With this in mind, here are a few important considerations you need to take into account when choosing the best mattress for the baby crib.

Types of Crib Mattresses

Generally, baby mattresses either have a foam or an innerspring construction. As long as they’re made of high-quality materials, both types can be a solid pick for your kid.

Foam Crib Mattresses

Mattresses made of polyfoam are typically more affordable than innerspring models. Another advantage of foam beds is that they’re lightweight, so you can easily change sheets.

If you decide to get a foam baby bed, choose resilient models that quickly come back to their original form after being pressed. The top rated crib mattress shouldn’t closely conform to a baby’s body since this might pose a safety risk.

Also, you should look for foam of a higher density because it provides a firmer sleeping surface, which is recommended for infants. Besides offering ample support, a firm mattress is also safer than a soft option.

Innerspring Crib Mattresses

An innerspring construction consists of a coil system, which is topped with several layers of cushioning materials. The comfort layer might be made of cotton, foam, or polyester.

When shopping for the best innerspring crib mattress, you need to pay attention to the coil count and gauge. The number of coils affects the mattress’s level of support, so it’s usually better to look for models with a higher number of coils. The gauge represents the thickness of the coils—the lower the gauge, the thicker the coil. Generally, thicker coils provide better support and make the mattress firmer.

However, innerspring mattresses might be heavy. Also, they’re usually pricier than foam models.

Organic

Organic models are made of natural materials, such as cotton, wool, and latex. Nowadays, many parents are looking for the top rated organic crib mattresses since they don’t contain any harmful substances. Plus, they owe their popularity to the fact that they’re generally hypoallergenic.

However, if you don’t get an organic crib mattress, keep your baby’s health in mind. Just be sure you check it complies with safety standards regarding the content of harmful substances. This is something that applies to all mattresses, not just the top rated baby crib mattresses.

Firmness Level

Regardless of the type of mattress you decide to buy, it’s crucial to look for a firm bed. Even though babies are soft and delicate creatures, they don’t need a cushiony sleeping surface like some adults.

Instead, a firm mattress will provide them with adequate support for their growing bodies. What’s even more important, it will create a safe sleeping environment. Indeed, the best infant crib mattress should offer a firm sleeping surface, while toddlers can sleep on a slightly softer bed.

To reduce the risk of SIDS, newborns and infants shouldn’t sleep on soft beds, which offer body contouring. According to expert recommendations, when you apply pressure to a crib mattress, it should quickly bounce back to its original shape.

Dual Firmness

Some manufacturers offer crib mattresses with dual firmness—the firm side is designed for infants and the softer side is meant for toddlers. Therefore, you can use the infant side during the first year of your baby’s life and then simply flip it once your child needs a more comfortable bed.

However, if you’d like the best cheap crib mattress, this kind of crib mattress might not be the greatest pick since it’s often more expensive than standard options with one firmness level.

Also, don’t forget to check with a pediatrician if your tot is ready for a softer bed before you flip the mattress.

Crib Mattress Size

The mattress needs to perfectly fit the crib. Therefore, the crib mattress dimensions should depend on your crib size. It’s important that there are no gaps between the mattress so your little one’s arms and legs don’t get trapped. The best crib mattresses in 2020 usually also have square-shaped corners in order to snugly fit the crib.

You can easily check if a mattress is the right fit by tucking your fingers between the mattress and the crib. If the gap is wider than two fingers, then you’ll need a bigger mattress.

Keep in mind that there are also federal government regulations, which prescribe that a mattress for a standard crib has to be at least 27 ¼” x 51 ⅝”. Plus, a mattress shouldn’t be more than 6″ thick.

Cover

Many of the best baby crib mattresses are made with a cotton cover. While this soft material is very breathable, it won’t protect the mattress from leaks. Therefore, you might also consider getting a mattress with a waterproof cover. Alternatively, you can use a waterproof mattress protector.

In case you opt for a polyurethane cover, check if the mattress features ventilation holes, which increase its breathability and prevent it from keeping unpleasant odors.

A Brand New or Second-Hand Mattress

If not properly cleaned or maintained, even the best rated crib mattresses might become a perfect spot for bacteria or mold growth. Therefore, used mattresses may pose a threat to your infant’s health. That’s why buying a new bed is always the best option.

If you plan to use this mattress for your next child, you need to clean it before storing it. Also, make sure you keep it in a dry place.

Safety First!

Picking the best crib mattress for your baby is more than thinking about your kid’s comfort and the nursery’s interior design. In the first place, it has to be about safety.

Sudden infant death syndrome (SIDS) is the leading cause of death in babies younger than 12 months. Even though its cause is unknown, and it can’t be prevented, you can considerably reduce the risk by following some simple guidelines:

  • Get a mattress that snugly fits the crib.
  • Choose the best firm crib mattress.
  • The crib should be empty: You should only use a fitted sheet and keep all the pillows, blankets, stuffed animals, and other soft objects out of the crib. That’s because they increase the risk of suffocation.
  • A baby should sleep on its back. This is considered the safest sleeping position since it lowers the risk of SIDS.

Wrapping Up

Considering that infants need 12 to 15 hours of sleep a day and toddlers need between 11 and 14 hours, it’s crucial to get the best crib mattress for your little tot. Fortunately, there’s a wide range of high-quality options, and we’re here to help you narrow down the choice and make a well-informed decision.

FAQs

Which crib mattress is the best?

Our top three picks are Naturopedic, Newton, and Sealy. However, there are other great brands that offer high-quality crib mattresses, so we recommend you check out our top 11 list above.

Whatever choice you make, it’s vital to look for a firm mattress that snugly fits your crib. Plus, it has to be made of safe materials that don’t contain any harmful substances.

What is the best type of mattress for a newborn?

Most crib mattresses on the market are either innerspring or foam models. Both types are equally good for newborns as long as they’re firm enough. Also, the mattress should be resilient, and it shouldn’t closely conform to a baby’s body.

What is the safest baby mattress?

To be safe, a baby mattress should be firm, and it should quickly bounce back to its original shape after being pressed. Such a mattress reduces the risk of SIDS. It’s also essential that it’s made of safe materials that don’t contain any toxic substances.

Are foam crib mattresses safe?

Yes, foam crib mattresses are perfectly safe if they’re made of high-quality materials that meet the standards regarding the content of harmful substances. Also, look for those made of high-density foam because they’re firmer and don’t provide body contouring.

How do I know if my crib mattress is firm enough?

If a mattress quickly regains its original shape and it doesn’t conform to your hand when you press it on its edges or in the center, it’s firm enough for your baby. Also, don’t worry if a mattress seems too firm for you. Babies need a firm sleeping surface since it provides the best support for their growing bodies.

How high should a crib mattress be for a newborn?

According to US regulations, crib mattresses can be 6 inches thick at most. During the first months of your baby’s life, you can keep the mattress at the highest position. However, when your baby starts sitting, you’ll have to switch the mattress to the lower setting.

Can babies sleep on a memory foam mattress?

No, babies shouldn’t ever sleep on a memory foam mattress because this material conforms to a sleeper’s body, and it might increase the risk of SIDS.
