It is the parent’s general notion that their children deserve the best possible care and products they can afford.

One of the most important things in the healthy development of your child is a night of good sleep. Proper bedding systems should help your baby to sleep well, and provide the necessary support for their spine and neck.

If you are a parent looking for the ultimate crib mattress for your baby or toddler, choosing a good one is not an easy task. Check out the article below to aid you in your search for the best crib mattress for your little one.


3 Main Types of Crib Mattresses


The foam crib mattress is made of polyurethane. It remains a very popular choice for parents and is generally cheaper than innerspring or organic options.

Like other types of mattresses, foam mattresses are also available in a variety of different depths, the most popular being between 3 and 6 inches.

They are also the lightest of the three options which make cleaning the baby mess and changing the sheets an easier task.

Most polyurethane models out there weigh less than the innerspring. However, its significantly lesser weight is good once you think about how many times you’ll be cleaning it or changing the sheets.

Basically, a typical polyurethane baby mattress weighs approximately 7 – 11 pounds.



Although an innerspring baby mattress is usually more expensive than the polyurethane counterpart, this still remains a hugely popular option.

The firm level of support provided by the coils or springs of the mattress is great for orthopedic support and safety.

Moreover, an innerspring type of mattress is one of the most popular choices for full-size mattresses. Thus, parents tend to stick with what they have experience with and what they already know is of high comfort.

Comfort and support are measured in the number of coils inside. Common coil numbers are between 50 – 200; the more springs inside mean more cost, but this isn’t the only way to measure firmness.

Wire thickness, if stated in the product description is a handy way to measure firmness level. A lower gauge means a thicker wire, which is stronger and therefore firmer. For best results look for one with 150+ coils and a gauge of 15.5 or lower.



Over innerspring and foam, when it comes to price, the organic crib mattress is usually the most expensive; however, there is a good reason for its significantly higher price.

Organic mattresses are the healthiest available as the 100% organic material, which is usually cotton, eliminates potentially harmful chemicals and allergens.

Of the many different materials used in foam mattresses, some can be harmful to your child’s health, especially if they are prone to allergies.

Considering that your child will be in close contact with the surface of the mattress and its contents on a daily basis for some years, it’s important to recognize the potential long-term hazards of using traditional polyurethane types instead of a healthier organic mattress.


How to Choose the Perfect Crib Mattress

When adults are looking to buy mattresses, we most commonly look for one that provides comfort, support, and possibly pain relief after a hard day at work.

However, when it comes to our own bedroom purchase, we ironically often forget about safety. With this thought in mind, when choosing for children, safety is the one thing that we absolutely cannot neglect.

Weighing up which baby crib mattress to buy is probably one of the most important nursery decisions you’ll make when it comes to your child’s safety and well being.

Finding the best crib mattress is no easy or quick choice, and that’s why the below factors are crucial for anyone in the market for choosing the perfect crib mattress.


Compliance Standards

All crib mattresses must comply to 16 CFR 1632 and 1633 federal flammability standards. If buying a product with foam, it should be CertiPUR-US® certified.

CertiPUR-US® verifies that the polyurethane foam inside the mattress meets standards for content, emissions, and durability, and has been analyzed by independent, accredited testing laboratories.

The GREENGUARD certification is also worth taking note of as many products will advertise it.

The GREENGUARD certification assures the customers that the products they purchased which are designed for use in indoor spaces meet strict chemical emissions limits, which contribute to the creation of healthier interiors.

When it comes to buying an organic mattress, the best way to tell if it’s genuinely organic is by checking whether the GOTS had already certified it.

Although there are many GOTS approved certifiers throughout the world, the largest certifier in the US is OTCO.


Firmness Level

Most of the experts have the same opinion regarding the firmness level of a mattress. it’s already known in the industry that it is better to have a firm crib mattress over a soft mattress.

According to the Center for Disease Control and Prevention, the main death cause for infants in the United States of America is the Sudden Infant Death Syndrome, or commonly known as SIDS.

SIDS is caused by suffocation hazards which are a consequence of a soft sleeping surface. Therefore, it is important to note that the bedding should snap back when you press it on the center and the thresholds.

Experts have repeatedly emphasized that a mattress shouldn’t conform to the baby’s head shape. It is recommended that the bed should be resilient enough to regain its shape quickly after applying hand pressure on it.

However, there are various types of foam which have two levels of firmness. The first level is soft, which is meant for toddlers.

The second one has a slightly higher firmness level intended for infants. As far as infants are concerned, it’s safer to go with the firm rather than soft.



A well-designed mattress should not only make your baby’s sleep more comfortable but should also give support for healthy spine development.

The mattress’ material is one of the most important aspects you should consider. Try to find a long-term, comfortable bed since your child will probably sleep in a crib until the age of three.

A mutual opinion on whether a foam or innerspring type is better for the baby doesn’t exist so you should carefully research before you buy.



When it comes to buying a good baby crib mattress, you might not want to try bargain shopping. However, you should also know that buying an overpriced one won’t do you any good.

The price of a standard crib mattress is normally a good indicator of quality, but there are other important aspects you should look into.

Although there are other factors to take into consideration, usually the price all depends on the quality and type of crib mattress you opt for.

Generally, the cheap and thinner foam mattresses are in the low budget range. The better and denser models will cost a little more. However, the price is usually tolerable once you understand that the more expensive ones are of much higher quality.

In the mid-range, Innerspring models are the more popular option and fall. Organic mattresses are slightly pricier but for a good reason. Usually, organic types are the most expensive among all the other types of mattresses.



There is no right or wrong size. However, there are some regulations. The minimum size proposed by the government is in a range between 27 5/8″ to 28 5/8″ of width and 51 3/4″ to 53″ in length.

The minimum size should be 27 1/4” x 51 5/8” and the bedding shouldn’t be thicker than 6 inches. The main rule is to have it fit the crib snug or moderately snug.

The depth differs between 5 to 6 inches for coil crib type and 4 to 6 inches for foam-based products. Generally, if the gap is more than two fingers, the mattress is too small.

The gap between the mattress and crib sides can pose a severe risk of suffocation which is why a gap of no more than 1.25″ should be present between the edge of the mattress and the frame.

Some places you will read this as “no more than two fingers” but this is not accurate advice, 1.25″ is the correct measurement.

The depth or thickness of a U.S compliant standard crib mattress size can be no more than 6″ from top to bottom when laid out flat.

Lastly, one common thing that often leads to confusion is the difference between a toddler mattress and baby crib mattress.

The truth is there is no difference; concerning size and compatibility, they are the same. So for example, if you have a 3 in 1 or 4 in 1 convertible baby crib, once your baby is ready to transition from crib to toddler bed, the same one can be used.



When choosing the right crib mattress, it is a good idea to buy a waterproof mattress.

A good indicator that a mattress is water resistant is a double or triple ticking bolstered with nylon. This kind of content will also show high resistance to being teared up or soaking other solids or liquids.

Most of the products have covers made out of cotton and you might want to buy waterproof covers instead. You should also take notice of the airflow in and out. It should have venting holes which will release the odor from leaking diapers.
