When you bring your baby home after the delivery, they may spend a lot of time sleeping in the bassinet. After some time, however, they will outgrow it and need to transition into a crib so that they can sleep more comfortably through the night. The question is, how do you know what the best crib mattresses are out there?

With that thought in mind, we built a list of the 10 Best Crib Mattresses in 2020 that may help you find a bed for your little one.

We hope that our recommendations below can make the search a bit easier for you. Let’s get started.


How To Choose A Crib Mattress – Buying Guide

When it’s time to choose a mattress for your little one’s crib, making sure that the features met whatever criteria that you value. Because of that, we wanted to be sure that the mattresses recommended above have the qualities that you want to see in the best crib mattresses on the market. Here are the aspects to consider before buying one:


When you pick a mattress, it needs to fit snugly inside the crib without any spaces between the mattress and the frame. The reason is that this gap can become a safety hazard as your child’s head may get trapped in it and suffocate them. The federal government standardizes the size of both crib and mattresses for infants. However, due to minor variations, not every bed will fit into your crib of choice perfectly.


A firm crib mattress is better for your baby compared to a soft one. While it may feel too hard and stiff for you, the stability of the bed is ideal in making sure that their developing body won’t sink in it. 

Parents can see how firm the bed is by pressing your hand on the center and edges of the mattress. If it conforms to your hand, you should look for another bed. If it does not, then congratulations—you have found a firm mattress.


Typically, density is not listed on the packaging for the crib mattress. Despite that, you want a highly dense bed to make sure that it is firm enough to keep your little one safe while they are fast asleep. 

On a foam mattress, its weight can be a good sign of the density. With innerspring mattresses for cots, the gauge of the wire used on the springs can tell you how dense it is as well. You want to look for lower numbers as they indicate that the wire will be more durable, and the mattress will be firmer.


Resiliency relates to how well a crib mattress retains its shape. The rule of thumb is that your sleeping child should not be able to leave an impression on the foam since it means that the cushion is on the softer side. This softness can make it difficult for them to change positions in bed because there is already an indentation in the mattress. Many foam mattresses that are labeled as “2-stage” or “dual firmness” have a firm side for infants and a soft side for toddlers.


Breathability is a significant thing when it comes to your little one’s mattress. To make sure that the product is well-ventilated, manufacturers have created small holes on the sides for maximum airflow. These vents will allow the bed to smell better over time. 

Such a feature is vital because cot mattresses are prone to get soaked in an infant’s pee, milk, or sometimes even poop. The less odor combines with the stench of the latter, the easier it can be to make the mattress not too smelly.


Like many other products on the market, baby crib mattresses can come in a wide variety. When shopping for the best mattress for your little one, therefore, knowing the differences of each type may prevent you from spending on an item that you will eventually need to return when you realize that’s not what your baby needs. Here are the different types of baby mattress:


A foam mattress is the cheapest and most basic mattress option for your little one. Made of lightweight foam, it can be a great choice if you have a portable crib that you fold up when not in use. The materials used to make this type can be polyurethane, bamboo fiber, or latex to help ensure that it won’t become as thin as a paper as months pass by.

Foam mattresses for cot beds come in different densities with varying levels of firmness. As mentioned throughout this article, a firmer and denser mattress can be a much safer option for your baby than a softer one. Six inches is the ideal thickness of a foam bed, but you may also get a three-inch one during the summer to keep the infant from sweating in their sleep.


Otherwise known as a coil spring mattress, the innerspring mattress has gotten its name from the fact that manufacturers build the core with coiled steel springs. Because of this primary material, this type of bed can be much heavier than other types and is a bit difficult to move around.

A word of advice to parents: avoid cheap coil spring mattresses for a cot. While the manufacturer may claim that they are of high quality, you can tell that that’s a lie when the bed squeaks no matter how small your child’s movement may be. This can not only keep you up all night if the crib is in your bedroom but also disturb their slumber.


A lot of parents do not like the idea of their child lying on a mattress that may have been treated or manufactured using harsh chemicals. After all, the latter can irritate their sensitive skin or cause an allergic reaction. To resolve the matter, companies have started incorporating more natural ingredients in their mattresses to give children a soft, comfortable bed to lay on at still. 

Nevertheless, you may want to do some research before buying this type of mattress because parents cannot rely on the words ‘certified organic’ on the label alone. It may only contain small amounts of natural materials, which is not what you are after. Try to look for the entire list of components, as well as read reviews about it to ensure that you are paying for what you want.

Memory Foam

One of the newer types of mattresses, memory foam is temperature-sensitive and can mold itself to the body shape of the infant. During the colder seasons, the bed will become more pliable as your child lays on it every night. However, in the summertime, it may be a little uncomfortable for your baby to lie on as the mattress’ reduced air circulation can make it a bit warmer.

Considering parents are thinking of buying a memory foam mattress, be sure that your child is over a year old already. It is not advisable to put a young infant in one because they may sink in the mattress and be unable to get out of it. 


Q: Is foam or coil mattress better for baby?

A: A coil mattress is better for a baby than a foam mattress. The former is thicker and firmer compared to the latter, so the child will not sink in it.

Q: Are foam or spring mattresses better for babies?

A: Spring mattresses are better for babies than foam mattresses. The reason is that infants are not strong enough to push their body or face off the bed, especially when they are on their belly. If it takes place when a parent or caregiver is not around, it may lead to suffocation or, worse, sudden death.

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

A: You can tell if your crib mattress is firm enough by pressing on it. In case your hand sinks into the bed, then it is too soft for the baby. If the mattress barely gives in to your hand’s pressure, then you know that it is firm.

Q: Are foam crib mattresses safe?

A: No, foam crib mattresses are not safe. This is because their softness makes it almost impossible for babies to breathe when they fall asleep on their tummy. It typically results in the infant experiencing SIDS.

Q: How thick should crib mattress be?

A: The ideal thickness of a crib mattress is six inches. What you will get can be a little thicker or thinner than that, depending on how easy it is for your baby to sweat while sleeping on the bed.

Q: When can you flip a crib mattress?

A: Parents can typically flip a crib mattress once your baby turns one year old. This is when they have control of their head and neck muscles. It won’t be tricky for them to turn their face or roll around if the mattress feels suffocating.

Despite that, you should not flip a crib mattress until your child is ready for it. The other side of the bed is more padded than the current side, so the baby might sink into if they do not have physical control.

Q: Should a toddler have a firm or soft mattress?

A: A toddler should have a slightly firm mattress. You cannot give them an extra soft bed, especially when they are transitioning from a crib mattress. Although they may be able to manage their movements, the softness of the bed may still smother them.

Q: What are the benefits of using a baby mattress?

A: Here are the benefits of using a crib mattress for infants:

  • Comfort – The primary function of the best baby crib mattress is to give them a comfortable place to sleep at the end of a long day. It is not as hard as wood but not as soft as a pillow to guarantee their safety.
  • Convertible – Many baby crib cushions these days are more than just a bassinet for your little one. Mostly, as double-sided mattresses, they are designed to convert into their first toddler bed. Having a cushion that can go through this transformation is very beneficial, especially for budget-conscious parents.
  • Eco-Friendly – Various manufacturers have started to create products that use environmentally friendly materials. This can be ideal for your children because it entails that they have lesser chances of coming in contact with some harmful chemicals or substances that used to give babies skin irritation and other illnesses.
  • Cost-Effective – Parents can quickly get an excellent mattress for a cot if you have $100 or $200 of available cash. Of course, there are some higher-priced options out there, but practical moms and dads do not need them.
