It is designed with safety standards and hygiene in mind to provide your baby with a superior level of comfort that doesn’t sacrifice functionality. It is also 100% recyclable so when you decide its lifespan has reached an end, you can easily dispose of it without it winding up in a landfill, as many baby mattresses unfortunately do.

This crib mattress is also GreenGuard Gold certified which means it is free from any harmful chemicals and reduces its VOC emissions.

Firmness, Support, and Comfort

Unlike some of the other best crib mattresses, the Newton does not feature dual firmness. Instead of providing two firmnesses, a softer one for the toddler years and a firmer one for infants, this mattress aims to be somewhere in the middle.

Breathability and Temperature Regulation

Wovenaire also excels in temperature regulation. Its open-air structure ensures it won’t retain heat from your baby’s body by actively dissipating and redistributing it all night long. Preventing overheating at night will allow some more restful baby sleep while also decreasing the chances of SIDS, which many believe can be attributed to being too hot.

Maintenance

The Newton baby crib mattress is 100% washable so you can rest assured your baby sleeps on a clean and sanitary surface free from bacteria, even when you hand it down to another child.

How To Pick The Best Baby Mattress

With all of the options and the seemingly limitless variations, it can be difficult to know how to pick a crib mattress that works for you and your child. This guide will help you determine what to look for when buying a crib mattress so you can make a knowledgeable decision that you will be happy with in the end.

Size and Height

When choosing a frame, you may find yourself wondering, how long are crib mattresses? Crib mattresses have a regulatory size to ensure safety across brands and to prevent gaps between the frame and the mattress that could cause small children to get trapped in their cribs.

baby wearing a bonnet

The U.S. Consumer Product Safety Commission (CPSC) regulations state that a crib mattress must be at least 27 ¼ inches wide by 51 ¼ inches long. The CPSC standards also require a crib mattress to be no more than 6 inches thick so small children will not run the risk of toppling out of the crib by falling over the top of the bars.

Many people prefer a crib mattress that is thinner than 6 inches so it provides minimal loft. The taller the crib mattress, the more likely a child will be able to climb out as they grow which could pose a potential threat or cause injury.

Materials

Just like mattresses for adults, the best crib mattresses are available in a variety of materials and structures that offer varying levels of supportive comfort which cater to specific needs and sleep preferences. When it comes to a foam vs a spring crib mattress, the main difference is weight. A spring mattress will generally weigh more than a mattress made from foam. An organic mattress may have different specifications entirely.

The weight of the crib mattress can make a difference if you anticipate moving it frequently for things like travel, or to clean after an unexpected accident. People with limited mobility may also have trouble moving a heavier crib mattress without assistance. Consider the weight of the mattress if you fall into one of these categories but for the most part, crib mattresses can be moved with ease from one place to another by an adult – an innerspring mattress may be lighter than a foam mattress.

Let’s review more about what makes different types of crib mattresses unique.

Innerspring Mattresses

Innerspring mattresses have been around for a very long and considered traditional. They consist of a series of coils that respond to pressure applied by body weight. Innerspring baby crib mattresses are often more expensive and heavier options but can be more durable and last longer without showing signs of wear. Additionally, some innerspring mattresses will include border rods for additional edge support.

Foam Mattresses

Foam crib mattresses can be comprised of varying types such as memory foam and polyfoam. They come in a variety of thicknesses and firmnesses as well, some are double sided which means they feature a firm side and a softer side. Make sure you choose a firmer one for infants and small children to help them sleep on their back all night without rolling over onto their stomachs. Keep in mind that they tend to be lighter and easier to move than spring mattresses which can be helpful when cleaning frequently.

Organic Mattresses

They come in a variety of materials such as wool, natural latex, cotton, and many more. Many parents prefer an organic mattress because they do not contain chemicals that could potentially pose a threat if they release gas. They do not use flame retardants, vinyl, or polyurethane in their construction.

Material Certification

Strict regulations are enforced for crib mattress manufacturers regarding emissions and chemical components. All crib mattresses must be GREENGUARD Gold certified which denotes minimal emissions of volatile organic compounds (VOCs) and other chemical components which pose health risks after extended exposure.

These crib mattresses must also be CertiPUR-US certified which guarantees they do not contain harmful chemicals such as lead or formaldehyde.

In addition to the two previous certifications mentioned, any product being advertised as an organic mattress should also be Global Organic Textile Standard Certified (GOTS) and/or Oeko-Tex Standard 100 certified.

Make sure you check the certifications each mattress has to ensure it meets all the guidelines and more.

Round vs Square Corners

Crib mattresses come with either rounded or square corners. Square corners provide a snugger fit along the edge of most crib frames. This ensures you will not have a gap between the frame and the mattress which should be avoided to prevent pinching. Some find the square corners can be too pointy for their preference though, and they worry about poking. Some may suit certain crib sheets better than others, too.

Rounded corners will prevent poking from happening but may also create little pockets for things like pacifiers to fall into because the mattress does not fit flush to the walls of the crib in the corners. There are benefits and drawbacks to crib mattresses with either rounded and corner crib; make sure you choose what is right for you and your family. You don’t have to stress about this minor detail too much.

Firmness, Support, and Comfort

The ideal crib mattress for a newborn or infant will be firm and offer a lot of support. These traits help a baby remain on their back all night long, something that is strongly recommended to reduce the risk of sudden infant death syndrome (SIDS), a disease also referred to as cot death or crib death. Aside from SIDS, a baby runs a higher risk of suffocation when sleeping on their stomach at a very young age so sleeping on their back is the ideal position to reduce the risk and ensure a safer sleep.

The best crib mattresses for babies are firm and are supportive enough to prevent them from rolling over onto their stomachs during the night. Adversely, a softer crib mattress is too conforming and will make it easier for them to roll over. Thus, they should be avoided for infants.

However, keep in mind that the mattress you use for your crib may not be the same one you want to use as your toddler bed mattress. Softer crib options are more suitable as a toddler bed mattress and are not recommended until your child is a little older. Some crib mattresses are double sided so the mattress can change to suit your child’s needs as they grow. These mattresses have a softer side for toddlers and have a firm side on the other for infants. This is a good option for a lot of families that offers diversity and saves some money in the long run.

Temperature Regulation And Breathability

One of the leading environmental causes suspected of contributing to SIDS is overheating in infants. This makes temperature regulation and breathability very important when deciding which crib mattress you should buy. The right mattress will help control body temperature throughout the night allowing your child to sleep safer and more comfortably.

Breathability also ranks really high on determining factors in top rated crib mattresses because they are good at preventing suffocation. Infants run a high risk of suffocation in the first few months before they have the strength and mobility to move their limbs and body more freely. Anything we can do to mitigate the threat of suffocation in infants, like increase breathability in a mattress, is a welcome and necessary adjustment. An innerspring mattress often has excellent airflow due to the construction of the core. 

Cloth covers retain more heat than a vinyl cover, but vinyl is less breathable than cloth. To combat this, many crib mattresses with vinyl covers are aerated or perforated in some way to help facilitate and promote more airflow and breathability.

Crib mattress reviews often rank mattresses with cloth covers that have been treated with a layer of polyethylene the highest because they provide a level of protection against liquids while still preventing overheating in small children.

Durability, Warranty and Affordability

The length of the warranty should be the first indication of its durability. Many people overlook the importance of durability in a crib mattress because they don’t expect to use it for more than a few years, three is pretty standard, before switching to a bigger bed. However, the same crib mattress can be used for future children as well if it is durable enough. Purchasing a high-quality crib mattress now may save you from having to buy again as your family grows.

Simply put, having a baby is expensive. Almost all expecting parents anticipate costs with a new baby and create a budget to prepare. With this in mind, the cost of a new crib mattress can play an important part in your decision. Of course, parents want to provide their kids with a comfortable and safe mattress, but the cost can be the determining factor for many people in the end. Fortunately, there are so many good quality options available on the market today that you will not have to sacrifice quality for affordability.

Waterproof vs Cloth Cover

When it comes to good quality crib mattresses, the cover material is very important. You want it to be breathable and of course safe. Most crib mattresses come with either a waterproof cover made from polyurethane or vinyl. They may also come with a fabric cover that can be made from materials like cotton or nylon.

Babies and small children use diapers, but they do not always eliminate leakage or prevent accidents from occurring. Bottles also have a tendency to leak or possibly come open if not properly sealed which can lead to a big mess. Many parents prefer to purchase a crib mattress with a waterproof case for precisely these reasons.

However, it does not mean you should ignore the many great choices available that have cloth covers. It simply means you should strongly consider purchasing a waterproof fitted-sheet to make your crib mattress as easy to clean as possible. When considering price, you may want to factor this additional cost into the total price if you are choosing a crib mattress without a built-in waterproof fabric cover.

At first, you may think this is only important for heavier people and couples who wish to maximize the usable surface area of their beds. However, it can be equally important for a crib mattress, only for different reasons. Some will include edge support in the form of border rods, while others will feature a denser foam.

Reinforced edges on a crib mattress prevent shrinkage when a small child rolls over. This is important to help reduce the potential for accidental injury from being pressed against the side or being wedged between the mattress and crib wall. In extreme cases, these scenarios could even cause suffocation. Edge support and a crib mattress that snugly fits into the bed frame will help mitigate this problem.

Unfortunately, many of our choices do not feature border rods, or any other specific edge support however, sometimes the firmness of the mattress is enough to prevent rolling.
