8 Rated Baby Crib Mattresses Reviewed

Graco – Best Non-Toxic


  • Breathable polyfoam
  • Greenguard Gold certified
  • Quilted polyester cover
  • Moisture barrier
  • Standard full-sized crib
  • 5-inch profile

In our opinion, the best crib mattress is Graco. Foam-based mattresses that are meant for cribs usually have stricter guidelines about potentially harmful chemicals, but some go even further. This non-toxic Graco model should be free of phthalates, mercury, and lead, and has a Greenguard Gold certification, making it safe for babies, as well as appropriate for hospitals.

It is a standard-sized crib mattress with a polyester cover. It has a moisture barrier to keep any accidents on the surface, and additional isolation layers to keep the core secure. That core is a 5-inch layer of aerated polyfoam, which should provide all the support your baby needs to grow and develop.

And, as the foam core is breathable, its surface should remain refreshing regardless of how hot the weather might be, which should help your baby get a more relaxing night’s sleep.

So, if you’re looking for a safe mattress with no harmful chemicals, this one might be what you need. It should still support your baby correctly while being waterproof and durable, but it is made without harmful ingredients, and the off-gassing should be negligible.

Safety 1st – Best Lightweight


  • High-density thermo-bonded core
  • Greenguard Gold certified
  • Waterproof vinyl cover
  • 7.5 pounds of weight
  • Full-sized crib
  • 5-inch profile

There are many reasons you might want a lightweight mattress for your baby’s crib. You might want to be able to move it around, or you might want it to be more manageable and simpler to maintain. This Safety 1st model should provide just that, weighing in at only 7.5 pounds.

What makes it lightweight is its use of a high-density thermo-bonded core instead of foam. That means that it uses non-toxic polyester fibers which are then bonded by high temperature, making the core light, durable, and still firm enough to support your baby’s weight correctly. And, as it is Greenguard Gold certified, its off-gassing should be negligible.

That core is then wrapped in a waterproof vinyl cover, which should help protect it from any accidents, keeping the moisture trapped on the surface. That should also make it easier to maintain – you simply need to wipe any stains from the surface, and it is as clean as it can be.

That’s why this mattress can be ideal for those that want something that can be moved around without problems. And, while being lightweight, it is still safe and firm enough for your baby.

Dream on Me – Best Portable


  • Pocketed mini-coils
  • Waterproof cover
  • Greenguard Gold certified
  • Mini crib size
  • 3-inch profile

If you want a mattress meant for portability, this Dream on Me model should provide for all your baby’s needs. Its small size should fit into any mini-sized crib with a length of 38 and a width of 24 inches.

Despite a profile of only 3 inches, it should still provide plenty of support for your baby. To achieve that, it uses a core of pocketed mini coils, which should provide all the reinforcement that innerspring models give, all with lower thickness.

Its cover is waterproof, so it should be able to withstand any accident your child might have, as well as being easy to maintain. And, since it doesn’t use foam, it doesn’t put your baby in any danger of off-gassing, or exposure to any chemicals that might have been used during manufacturing.

Those that are looking for a safe and portable mattress that can fit into a standard mini-crib, this one might be what they need. Apart from providing ample support, it should also be free of harmful components, as testified by its Greenguard Gold certificate.

Newton – Best Hypoallergenic


  • Bonded polymer fiber core
  • Breathable cover
  • Greenguard Gold certified
  • Full-sized crib
  • 5.5-inch thickness

If you want to keep your baby safe from allergens, as well as any other potentially harmful components, this Newton crib model might be what you need. Its base isn’t made from any kind of foam, latex, or coils. Instead, it uses a distinctive Wovenaire core constructed from bonded polymer fibers.

That way, the base is breathable enough to always keep the air moving, all while still providing plenty of support. And, with that improved airflow, you can be sure that none of the harmful chemicals commonly used in manufacturing can reach your baby.

At the same time, the breathable cover should prevent any allergens from entering the mattress while still keeping the air flowing. And, both the core and the cover are fully washable and easy to maintain.

So, if you want to minimize the number of components that could hurt your child, this mattress should have what you need. And, while being safe, it also correctly reinforces your baby’s body.

Colgate – Best Orthopedic


  • Foam core
  • Organic cotton cover
  • Greenguard Gold and CertiPUR-US certified
  • Full-sized crib
  • Dual firmness levels
  • 6-inch profile

This Colgate model comes with two different firmness levels. One side is more firm to provide the extra support your baby needs to grow and develop correctly, while the other should be soft enough for most toddlers, providing them the comfort they enjoy.

It is an organic mattress, using an eco-friendly polyfoam core wrapped in a waterproof natural cotton cover that is also hypoallergenic. That should keep all the harmful particles away from your child, all while being easy to wash and maintain.

To do all that, its core uses two layers of foam, one firmer and the other softer. All of that is then enclosed in a fire-proofing layer, which is then covered with the breathable organic cotton outer layer. That way, the core is kept away from your baby, who is only in contact with the cotton cover.

All this makes this mattress a clear choice if you want something that can provide a healthy and supportive surface for your baby. It should do just that – correctly prop your child up during their infancy and toddler years.

Milliard – Most Comfortable


  • Memory foam and polyfoam
  • Waterproof washable cotton cover
  • CertiPUR-US certified
  • Full-sized crib
  • Dual firmness levels
  • 5.5-inch profile

Like many others, this Milliard crib mattress provides two different firmness levels at its two sides. The firmer one, more ideal for babies, provides all the reinforcement that they need to grow and develop healthily.

The softer side, however, uses memory foam, and it should be even better at shaping itself to your toddler’s body, providing them with the extra comfort they need. And, as both the polyfoam and memory foam layers are CertiPUR-US certified, you can be sure that no harmful chemicals were used to make them.

Its cover is made of cotton, and it is fully waterproof. It is also removable and washable, so maintenance shouldn’t be an issue. The cover is fully organic, making it extra safe, and it should keep any allergens away from your child.

That’s why this mattress could be ideal for those that want the comfiest option for their child. Its firmer side should provide a stable surface for them to sleep on, while the softer side should be more than comfortable enough for most toddlers.

NapYou – Best Reversible


  • Polyfoam and memory foam
  • Waterproof cotton blend cover
  • CertiPUR-US certified
  • Dual firmness levels
  • 5.5-inch thickness

If you want a crib mattress that can last from your child’s infancy all the way throughout their toddler years, you might want to buy a model that has two different levels of firmness. This NapYou option has just that – the firm polyfoam side should correctly support your baby, while the soft memory foam side should be comfortable enough for your toddler.

All of that is wrapped in a waterproof cotton blend cover that should also be hypoallergenic. That should make any mess your child makes easy to clean, and the maintenance more convenient.

To make sure it’s safe, both the polyfoam and memory foam layers are made with CertiPUR-US certified materials. That means that no harmful chemicals were used to make them.

The flippable nature of this mattress should ensure that it always maintains your child’s correct posture, from their infancy to their toddler years. Their back and neck should remain in a proper position, all to help them grow and develop healthily.

Serta – Best Waterproof


  • Innerspring
  • Waterproof cover
  • Greenguard Gold and CertiPUR-US certified
  • Dual firmness levels
  • 6-inch profile

When choosing a crib mattress, one of the most essential factors is whether the cover is waterproof. If it is, then the core should be safe from any accident your child could have when sleeping. That should, in turn, make the product last longer.

This Serta model comes with a waterproof vinyl cover that should make cleanup and maintenance even more straightforward. And, as the mattress uses steel coils to provide the support, it should be as responsive as it needs to be, all while offering reinforced edges. That should provide a stable surface for your toddler to stand on.

As it is a dual-sided mattress, it uses an additional layer of comfort foam on the plush side. That way, your toddler will have a softer surface to rest on, while the firmer side should keep your infant in a correct posture throughout the night.

So, if you want a waterproof mattress to help make the maintenance more manageable, this one should provide what you need. Its innerspring core should be safe from any moisture that might have an adverse effect, all while providing ample support on both of its sides.

Key Points in Choosing an Infant/Toddler Crib Mattress

Choosing a crib mattress can be difficult, especially if you’re a first-time parent. There are so many different factors to consider that you don’t even know where to start.

This section will give you an overview of the several main aspects, and what to look out for when looking at them.


There are many ways in which the materials the mattress is made of can be relevant. For starters, what the product is made of should determine the type of support your baby will get. Foam solutions are different from innerspring options. We’ll get into more details about those in a later section.

What you should pay attention to are the materials that make up the cover, the fire-proofing, and the separation between the two. The fire-proofing layer can contain several potentially harmful chemicals, and it must be separated from the outer cover by an additional layer.

Some parents prefer that their crib mattress is made of organic materials, and such models do exist.

Must be Certified

Primarily, you should be looking for a mattress with a Greenguard Gold certificate, as that means that the product was made with a minimal amount of harmful chemicals. It is primarily focused on volatile organic compounds or VOCs.

Additionally, mattresses can hold a CertiPUR-US certificate, which means that it doesn’t contain any harmful components such as lead or formaldehyde. These chemicals could have a negative effect even on adults, so it’s especially important to have them at least at a negligible level.

If you’re looking for an organic mattress, you should look for one with a GOTS certificate, as that should prevent the manufacturers from slapping the organic label on something that isn’t organic.

No Off-Gassing

Usually, when you buy a mattress, particularly those made of foam, they have a slight odor for the first several days. That’s why it’s usually recommended to give them several days to air out before sleeping on them.

The odor comes from the chemicals it is constructed from, and they can get stuck in the mattress before packaging. Crib mattresses, on the other hand, usually don’t have the smell, either because they have already been aired out, or they were made with a minimal amount of chemicals.

That’s why certifications are relevant. They signify that the product is made with less harmful chemicals and that those that were used won’t cause long-term health damage. As long as the mattress has a certificate, the off-gassing should be minimal.

Size of the Mattress

Models made for cribs usually come in a standard size. It is about 52 inches long and 28 inches wide, and its height shouldn’t be above 6 inches. As long as it follows those guidelines, it should fit snugly into the crib, all without leaving any space in the sides.

Apart from those full-sized models, there are also mini-cribs. They are usually more appropriate for people with smaller nurseries or not enough spaces in their bedrooms. If you have one of those, you’ll need a mattress that is 24 inches wide and 38 inches long.

Right Firmness Level and Support

The level of firmness can be challenging to determine. Your baby doesn’t have a preference yet, and that’s why it should be up to you to choose the right level. Generally, babies need a firmer surface for the first year or so. After that, a softer model could do, as well.

Usually, for infants and younger children, the firmness level should be a bit higher. The stiffer surface will support their bodies better and help them grow and develop healthily. If it’s too soft, they could sink too far, or they could roll over and suffocate. Their joints could also end in awkward positions, which could have harmful effects later.

As they grow and develop, and their movements become more coordinated, they could start to find softer surfaces more comfortable. That’s why it’s generally recommended that toddlers sleep on softer mattresses. They should still keep their bodies in proper positions, which should help their growth and development, while also providing them with enough quality rest.

Some mattresses have two sides – a firmer one for infants, and the softer one for toddlers. That way, you only have to invest in a mattress once, and your child gets to sleep on the same surface until they move to a proper bed. By then, they’ll already develop their preferences, at least to a level where they can tell you what they find comfortable.

Easy to Clean and Maintain

This is an essential factor as it makes it easier for you to maintain a clean and healthy sleeping space for your baby. Ideally, the mattress should have a removable and washable cover, and there should be a water-resistant layer under it.

Multiple layers should be preferred, as they will reduce the chances of anything leaking into the core, where bacteria or mold could develop and endanger your child. Clean sheets, cover, and mattress should create a clean and sanitary sleeping space for your baby, helping them grow and remain healthy.

Weight of Mattress

This primarily affects mobility, as more massive models can be more challenging to move around. Usually, crib mattresses weigh about 20 pounds, with foam-based solutions being lighter, and innerspring mattresses being heavier.

A model that weighs less should make it simpler for you to clean the crib, as well as remove and wash the covers should an accident happen. It could also make changing the sheets much more straightforward.

Models with more weight, on the other hand, can be firmer and more stable. That could make the nights much more comfortable for your child, and they won’t be able to move them as quickly.

Edge Support

With traditional mattresses, edge support is essential if you like to sit on your bed. It can be just as valuable for crib options, as well. For one, a model that has reinforced edges will not sink on one side, causing your child to roll towards the ends of the crib. Firm edge support should keep your child in the middle of the mattress while sleeping.

Toddlers, on the other hand, also like to stand on the edges of the mattress when they stand up in their cribs. If it’s reinforced there, it could make the bed much more durable, all while helping your child maintain balance.

Usually, innerspring models have superior edge support, and their foam counterparts aren’t as good in that department.

Material Used for Cover

The cover material can be even more crucial for crib mattresses. Firstly, you might want to avoid cheap models that contain plasticizers, as they might be harmful to your child. More expensive models should be free of them, and that’s why they’re generally a preferred option.

You should further try to find something that has a moisture-proof layer, either on top or beneath it. That should prevent any accidents from doing any damage to the core of the mattress, which could then develop bacteria or mold. Vinyl or nylon could be what you’re looking for, but you might also like something with natural non-resistant materials such as cotton.

There should also be at least a layer of separation between the top, the core, and fireproofing. Those should dramatically reduce off-gassing and keep any potentially harmful chemicals away.

Not Squeaky

One of the drawbacks when buying a waterproof mattress is that it can be noisy, especially if it’s made of vinyl. That could, in turn, keep your baby up at night, which should then keep you up, as well. This is one area where cloth covers are better – they may not keep the moisture from the mattress, but they are quieter.

Also, innerspring models are known to become noisier the more you use them, so if your toddler likes jumping in your crib, sooner or later, it will become squeakier. Foam is, on the other hand, not as bouncy, and it remains quiet throughout its lifetime.

Reasonable Price

This is another essential factor when considering buying a crib mattress. It will determine the build type, the materials used, as well as the cover quality.

While there are basic innerspring or foam models that cost less than $100, those usually don’t have any of the more advanced features. If, for example, you want a waterproof cover, it will cost you more. If you want something simple to clean and maintain, it should also increase the price.

Finally, if you want a fully organic model, be prepared to pay several times the price of the base models. They might be worth it, though, as they provide the healthiest sleeping surface for your child.

Best Material Types for Newborns

As we’ve mentioned earlier, there are several chief materials used to make these models. This section should give you an overview of the most common, as well as their pros and cons.


These have been the traditional types of mattresses for well over a century. You’ve probably slept on one in your crib when you were a baby. They are also the most common type in traditional beds, as well. So, are there any differences between those made for adults and those meant for cribs?

Like models made for adults, this type of mattress is made of many steel coils. Traditionally, those coils were joined together in a grid connecting them. Those models are usually bouncier, but they don’t isolate the movement, so when you move on one side, you’ll feel it on the other.

They can also be individually pocketed, which can then further boost their support. And, as they’re no longer connected, they don’t transfer the movement along the surface. These can be more expensive, though.

Gauge differences in the coils could also be vital. Thinner coils usually have a higher gauge, and they provide a softer surface. Those should be avoided, especially for the first year or so. Toddlers, on the other hand, can comfortably sleep on something plusher.

Another difference is in the quality of the build and materials used. Cheaper models use less expensive steel, which usually isn’t as durable as the more high-end types. That’s why mattresses that cost less regularly don’t last as long.

As far as advantages go, innerspring beds have several, the chief of which is their responsiveness. They are quick to adapt to any change in position your child can make, and they still provide plenty of support to help them grow. Also, they are bouncy, which some kids seem to enjoy jumping on.

That can be a drawback, as well, especially as the excessive jumping can dramatically lower the mattress’ life expectancy. It can also be annoying for the parents. These models are also not as good at adapting to your child’s body, which can make them a bit less comfortable than foam-based solutions. They are also heavier.

Overall, innerspring options can be a solid choice. They can be cheap, and the support they provide is adequate. They can also last longer than foam.


These are the most expensive types. They can easily cost you several hundreds of dollars. But what about them makes them cost so much? And are they really worth their price?

To be considered an organic bed, it needs to have a GOTS (Global Organic Textile Standard) certificate. That means that the materials used come from natural sources, and it usually includes organic cotton, wool, or latex. That includes both the cover and the core.

They can be based on steel coils, or they can use foam. Those based on steel springs have all the advantages and disadvantages that come with that type – they are more responsive and bouncier, but not as comfortable as foam.

Models based on foam, on the other hand, are usually better at shaping themselves to your child’s body but aren’t nearly as quick to respond as innerspring solutions.

The primary difference in quality, apart from the quality of the foam or springs, comes from the amount of natural matter in its build. To be considered organic and to receive the GOTS certification, they need to have at least 70%, but some go beyond that level and offer more. Those can, consequently, be more expensive.

Their primary advantage is their safety. They’ll be made from materials widely considered safe for your child, and their off-gassing should be negligible, further reducing the risk of harm. After a certain level, though, you’ll be dealing with diminishing returns – you’ll be paying much more for a minimal increase in quality.

Usually, these models should be the safest choice for your child. They will still provide plenty of support, all without the risk of exposure to some potentially harmful chemicals. They should also last longer, possibly all the way until your child moves to a proper bed.

They are also mostly two-sided. That way, you can use the firmer side while your child is still small, and turn it over when they get more stable.


This is another common solution, and mattresses based on polyfoam are generally among the most affordable options. While it’s possible to find innerspring models that are cheaper, foam-based options range in price from around $100 upwards.

Usually, polyfoam-based models are on the firmer side, making them more appropriate for babies. There can be differences in construction, though. Some dual-sided options could have a layer of memory foam on the softer side, for example. More expensive models can also use latex.

This is where things can get tricky. Polyfoam can be made with some potentially harmful chemicals, and there could be remnants of those trapped within the mattress. When you unpack them, there could be a faint chemical smell for several days until these odors air out. However, those chemicals should be gone after the first several days.

The off-gassing is more characteristic of memory foam, so if your chosen model contains a layer of that material, you should be extra careful and let it air out for at least several days.

Those can also get warm, so if you want such a mattress, you should make sure that the memory foam layer has at least one kind of cooling, whether it’s with increased airflow or an infusion of a cooling material such as a gel.

Foam-based models (check out our top rated memory foam beds) have several clear advantages, though. They are usually firmer, especially when using high-density polyfoam as their base. Another clear advantage over innerspring solutions is the lack of noise, so if you would prefer that your baby sleeps on a quieter surface, this may be the only option.

There are some drawbacks, though. They usually aren’t as durable and are likely to go flat after the first several years. Also, they aren’t as responsive and bouncy as innerspring models, which some kids enjoy. Their edges are usually not reinforced, as well, which could be detrimental if your child likes to stand in the crib.

Ways to Keep Your Crib Mattress in an Excellent Condition

If you want to make the best of your crib mattress, there are several things you should keep in mind. If you do the tasks outlined in this section regularly, the bed should last a much longer time, and your child’s sleeping surface should remain clean and healthy.

Clean it Regularly

You should regularly maintain the mattress, and that includes vacuuming it, as well as cleaning and disinfecting it. If you plan to use chemicals to clean it, you should let it air out just in case. That way, you should avoid unnecessary exposure to harmful chemicals, both for you and your child.

Along with the mattress, you should also clean the crib to make sure you remove any dust or other similar particles from your baby’s vicinity.

Flip it Regularly

If you rotate the mattress regularly, you’ll prolong its lifespan. You’ll avoid one side becoming flat and uncomfortable. This can be especially significant with innerspring models.

Of course, that only applies to the models that don’t have different firmness levels on each side. If you have such a solution, you should only flip it once your baby is stable enough to sleep on a softer surface.

Remove Stains

Before your child finishes potty training, they’ll have plenty of accidents, some of them while sleeping in the crib. Once that happens, you should clean both the mattress and the crib immediately. That way, you’ll avoid any potential problems down the line and keep the surface clean and sanitary.

Let it Breathe

Foam mattresses are known for their off-gassing, the release of chemicals trapped in packaging. While crib mattresses usually go through more rigorous testing to make sure that the off-gassing is minimal, you should still let the product air out for several days, preferably in a well-ventilated room.

Tips and Guidelines for Your Baby's Safety

Babies can be especially sensitive, especially during their infancy. That’s why you must do everything you can to remove any potential dangers from your baby’s vicinity. This section should give you all the information you need to do that.

What is SIDS?

Sudden Infant Death Syndrome (or SIDS) is, as the name implies, sudden and unexplainable passing of an infant. It usually happens in the first year of their life, with the most cases being between two and four months of age. It is also known as crib death, as it mostly happens in a crib.

The specific causes are, unfortunately, unknown, but several factors can increase the chances, and some babies are more at risk than others. Most of the time, it is a result of a defect in the region of the brain that regulates breathing, sleeping, or waking up.

Some environmental factors can also contribute and increase the chances, as well, and we’ll provide more information about those in a later section.

Who Is Most Affected?

SIDS mostly affects infants who either have a problem with their brain or their breathing. It can happen because the part of the brain that regulates breathing or sleep is underdeveloped or damaged in another way.

Sometimes, it comes as a result of a respiratory condition, such as the presence of allergens or cigarette smoke. It can also happen if the infant sleeps on their stomach, as that can cause them to have more difficulties breathing.

Babies who are born prematurely or with a lower weight are also in danger as their brains are not developed enough to correctly regulate their breathing and heart rate.

What are the Environmental Factors and Risk Factors?

Some environmental and physiological factors can increase the chances of SIDS, and in this section, we’ll go over the main aspects and how they contribute to that.

Environmental Factors

SIDS can affect infants who are too hot and are overheating, so you should make sure that the temperature in the bedroom isn’t too high. If it’s too cold, you should use several layers of clothes. That way, you can easily remove one if your baby starts to get too hot.

Sharing a bed with their parents can also increase the chances. Adult mattresses aren’t made for infants and usually aren’t an appropriate sleeping surface. They should sleep in the same room, but in their crib, at least for the first year of their lives.

There’s a reason why it’s usually recommended that your infant sleeps on their back – it makes breathing easier for them. You should pay attention to what position your infant sleeps in and make sure to always place them on their backs.

Finally, if the mattress is too soft, your baby could sink too far, which could further increase the chances, especially when combined with an inappropriate sleeping position. That’s why most of the mattresses in our selection have a firm surface (see our best firm mattresses list here).

Risk Factors

While it is still unexplained, SIDS does show preferences, and some infants are more at risk than others. As we’ve mentioned earlier, most cases happen between two and four months of age, but other factors can increase the probabilities.

For example, boys have a slightly higher chance of dying in their crib than girls. Also, nonwhite babies have a higher likelihood of developing SIDS for reasons that can’t be understood. If the infant had another case of SIDS in the family history, their chances are higher, as well.

Finally, babies that are born prematurely or with a lower weight have an increased chance of developing SIDS. Cigarette smoke also increases the odds, so if you do smoke, you should not do it around your child.

How to Prevent SIDS?

While the causes are still unclear, there are several things you can do to help reduce the chances. These can be crucial if your baby falls into any of the categories that have an elevated chance of developing SIDS.

The first thing you should do is to always place your infant in their crib, and place that crib in your bedroom. The baby shouldn’t sleep in the parents’ bed, at least not for the first year. That should, in itself, reduce the chances.

Next, the crib should be empty, with no pillows or plush toys in their vicinity. That way, they won’t have the opportunity to press their faces in anything soft, which should stop them from suffocating while they sleep.

The mattress should be firm, at least until your baby develops enough to become more stable. In the first year, the surface should be as stiff as possible to keep them in a correct position and help reduce the chances of them shifting into awkward poses during the night.

As we’ve mentioned earlier, they should always sleep on their backs. Side sleeping can also be dangerous, as they can flip to their stomach, which can cause difficulties with breathing. That’s why you should instruct anyone that has contact with your baby to always place them on their backs.

Temperature regulation is also vital, as infants that are overheating can have an increased chance of developing SIDS. That doesn’t mean that you should leave them uncovered; it means that you should be careful not to put too many covers over them. If you notice signs of overheating, remove a layer or two until your baby is comfortable again.

Several smaller things can also help reduce the chances. That primarily includes the usage of pacifiers, as they can help keep your baby’s breathing stable through the night. Breastfeeding for at least the first six months is also connected with a reduced chance of SIDS.

And some studies have shown that proper immunization can also reduce the chances of SIDS.

Frequently Asked Questions

Are Cheap Crib mattresses Safe?

That can depend on many factors, chief among them, its firmness and the materials it’s made from. If you’re looking for a cheaper option, you should make sure that the surface is firm, especially if an infant is going to sleep on it.

As far as the materials are concerned, most cheap models are made from polyfoam, which can have potentially harmful chemicals within. That’s why you should pay attention to any certificates the mattress can have, especially CertiPUR-US and Greenguard Gold. If it has one of those, it should be safe enough for your child.

What is the Best Crib Mattress Cover?

Any of them could be sufficient, but there are several factors you should consider when looking for a cover. For one, the material should be safe and quiet, and that ideally means you’d want something organic.

If that’s out of your price range, you can still find a cover that uses vinyl or polyurethane foam. In those cases, you should make sure that it has a certificate, as that should dramatically reduce any potentially harmful chemicals within them.

What is the Best Waterproof Crib Mattress Protector?

This primarily depends on what kind of a protector you’d want. You’d want something that can absorb the moisture, not allowing it to pool up or reach the core of the mattress. At the same time, it needs to be breathable enough that it can dry off.

And, as it likely will see its share of accidents in its lifetime, you’d probably want something simple to clean and maintain. A good grip with the surface of the mattress is also desirable, as it will fix it in its place under the sheet.


Choosing a crib mattress can be challenging. There are many factors you should consider, from safety to build, material, firmness, and price. It can be tricky trying to balance all these factors, especially if you’re a first-time parent.

It can be confusing to see all the different types. Some are made from foam, others from steel coils. Some have one certificate, others have another. Some boast about their features such as edge support, waterproof covers, or a different firmness level on each side.

This guide has given you an overview of top-rated mattresses for your baby’s crib, and any of them should be a safe choice. And, if none of those fit into what you need, we also presented you with enough information to make the decision much more straightforward.
