Ranking: The 3 best models of mattress for crib

The quality of the mattress is a very important factor for your baby’s health, because he does not have the structure of the spine fully stabilized, so if you sleep on a very soft mattress this can be harmful to your bone formation. Thinking about it, we separated the best models for your baby:

Buying Guide

Just as important as setting up the baby’s room is choosing the right mattress to accommodate the little ones. They can have different foams that alter the quality of the product.

Therefore, throughout this Buying Guide we want to guide you in this choice. That way, at the end of this article, you’ll know how to choose the best crib mattress for your baby.


What is a crib mattress and where to use it?

The crib is the place where the baby will spend most of the time, especially in the first months of life, when he can sleep up to 20 hours a day. For this reason, it is essential that you choose a good mattress to ensure the health and comfort of your baby.

Mattresses are essential for child development, especially in the orthopedic aspect. The body should be aligned and no part should be elevated, that is, you should not put pillows for babies up to one year old, otherwise the child will have growth problems that will only be noticed when he is older.

When the child feels discomfort on the crib mattress, he usually cries whenever he is put to sleep.

To choose the ideal mattress for your baby you must check the material, the dimensions (height, width and length) and the density. The material of the mattress should always be foam, never springs, as this option is not compatible with the bone structure of babies.

The density varies according to the weight, for children up to three years of age a D18 mattress is suitable (holds up to 40 kg), after the age of three it is good to exchange the mattress for a D23 model. It should be neither soft nor hard, but firm.

The mattress must not sink and cannot be deformable, any sign of these two characteristics must be changed. All parts of the baby’s body must receive the same pressure, that is, the head, torso and legs must always remain the same on the mattress.



It is recommended to turn the mattress once a month to maintain firmness and ensure durability, but be aware that some models have different sides. In most cases, only one side of the mattress comes with a waterproof layer.

If the mattress you want only has one waterproof side, you can choose a waterproof cover, which is on the underside of the cover and does not come into contact with the baby’s skin.

Another feature of the crib mattress is the treatments given to the fabric so that it becomes anti-allergic, anti-mite and anti-fungal, protecting your baby’s respiratory health.

Some models are also anti-reflux, which reduces the risk of accidents with regurgitation. If you don’t want to buy a mattress like that, just buy an anti-reflux pillow.

Regarding the dimensions, they vary between national and American standards. The national model is a little smaller: it is 130 cm long, 60 cm wide and 10 cm high, while the American type keeps 130 cm long, but gains 10 cm more width (70 cm) and is 12 cm high.

We have prepared a list of the advantages and disadvantages of the crib mattress, an essential item in your baby’s room.


  • There are two mattress options according to the dimensions: national and American model
  • There are waterproof mattresses, but usually only one side has this advantage
  • The mattress with density 18 can be used for children up to 40 kg
  • Some mattresses fit in the crib and on the mini bed


  • You need to be aware of the size of the crib to buy the right mattress
  • When only one side is waterproof, you cannot turn the mattress over
  • The mattress should be changed around the age of three

What differentiates a crib mattress from another?

The main difference between the mattresses is the size, the American model is bigger and can be used in the cradle and mini bed, while the national standard is slightly smaller, so it has a shorter service life.

Regardless of the choice, it is necessary to pay attention to the dimensions of the crib before buying the mattress, as it must have the exact size of the furniture, at most two centimeters off, to prevent the child from trapping the hands or arms in these spaces.

Check out a table with the main differences between the cradle and mattress of national and American standards:



How much?

The price of a crib mattress is usually quite affordable. It varies because of the size, density of the foam and brand, you will pay between R $ 150 and R $ 200.

Below that, quality may be compromised. Opt for a product in the mentioned price range.

Where to buy?

You can buy a crib mattress at furniture and appliance stores.

You can also buy online on e-commerces like Amazon, for example, you can compare models, prices and brands and still read the evaluation that other consumers gave for that product.


Purchasing Criteria: Factors to Compare Crib Mattress Models

Most crib models come with a mattress, but some brands sell these items separately. If it is your case, know that you need to be aware of some details, so you don’t buy the wrong model, they are:

  • Standard size
  • Foam density
  • Antiallergic
  • Waterproof

We will explain each of the items so that you do not have any doubts about which mattress you should buy.

Standard size

As we explained earlier, there are two models of cribs and mattresses, the national standard and the American. The national standard is slightly smaller, 10 centimeters less in width and 2 centimeters less in height.

The height of the mattress should never exceed 12 centimeters of the American model, because at that time the baby will not reach the cribs of the cradle when standing and this reduces the risk of falls.

The American standard is wider and therefore can be used for a longer time, it can also be adapted in mini beds. It is important to note that when the baby is newborn he may be frightened by a very large size, so it is important to use reducers.

Pay attention to the cradle model you bought or are going to buy to choose a mattress with a compatible size. Both models can be used in mini beds.


Foam density

To choose a mattress with the right density for your baby you can check a standard table set up by orthopedic doctors who indicate the right mattress model according to the weight and height of whoever is going to use it.

The most suitable model up to the age of three is the D18, above that age, it is recommended to exchange the mattress for a model D23.


As the baby’s immunity is low when he is very young, a great way to avoid allergies and other respiratory diseases, is to acquire a mattress in which the fabric has undergone a treatment against mites, fungi and other allergy-causing agents.

This detail helps your baby’s health, so read the product description carefully to see if the model you like has this extra functionality.



Another extra feature that you can look for in the mattress for your baby, is if the mattress, or at least one side, is covered with waterproof material.

With this coating, it will be much easier to clean liquid residues such as pee and vomit. Otherwise, it can be a nuisance to be without the mattress for one night if it doesn’t dry out in time.
