Safety Check Guide

As a parent, we are always worried about our children and their safety and that is why it is imperative that we have the safest crib mattress. There are many things that you need to think about when it comes to crib mattress safety such as:

  • the size of the mattress

  • how easy it is to clean

  • complying to the standards

  • fabric that your crib mattress is made out of

  • the firmness of the mattress

  • what cushioning layers it has

  • does it have border rods

  • the sheets that you place on the mattress

Did you know about all of these things?

It always recommended purchasing a new crib mattress since the used ones cannot last for a long duration. Furthermore, they may put your baby’s health at risk as they may hide dust mites and are generally unsanitary.

A great quality infant mattress has a lifespan of at least three years of it is well-maintained. However, you will need to replace the mattress if you see signs of wear and tear. According to health experts, parents should consider purchasing a 100% breathable mattress for their infants or toddler. On the contrary, soft mattresses tend to be suffocative and are considered to be one of the key factors for SIDS (Sudden Infant Death Syndrome).

To get the best deal, you have to focus on the basic qualities and some developed features that will make a good sleeping surface for your baby. Below are factors to consider when selecting the best baby crib mattress.

Mattress and Crib Size

The first thing is you need to make sure of is the mattress is the right size for the crib or bed frame that it is sitting on. Most of the time cribs and bed frames require a standard mattress so you don’t have to worry but you don’t want to always rely on that so just check it anyway.

The size of the mattress will depend on the interior dimensions of the crib itself. It is important for the mattress to fit perfectly without leaving any gaps as this could pose the risk of suffocation. There is no difference between the baby crib and toddler mattress in terms of size. You can still use the same convertible baby crib once your baby is ready to transition to the toddler mattress or use it as pack-and-play mattress.

Ease of Cleaning

The mattress that is waterproof can be cleaned easily as it protects the mattress from being stained. Not only does the cover offer the ease of cleaning but also prevents accidental diaper leaks from getting deeper into the mattress. The best models to clean are vinyl covers of ones that have a removable cover. It takes minimal effort while using a sponge and recommended soap for cleaning.

Compliance Standards

Like other products, all brands of crib mattresses should have a certification from a higher authority. This verifies that the polyurethane foam inside the mattress conforms to the standards for content, emissions, and durability. It shows that they have been analyzed by independent and accredited testing laboratories. They give an assurance that the product meets strict limits on chemical emissions and contributes to the creation of healthier interiors.

Materials Being Used On

If you want the safest crib mattress then you need to make sure that the size is correct for the crib or bed frame and also be aware of what it is made out of. Most crib mattresses have potentially harmful chemicals in the mattress, the cover, and even the tags. The chemicals are normally from the fire retardant spray that is on the mattress.

Firmness Recommendation

Another thing you need to be aware of in choosing a crib mattress is the firmness of the mattress. Most parents believe that the firmness of the mattress doesn’t matter and that the softer the better, but this is not correct. You want to make sure the mattress is firm enough that when your child sleeps they don’t sink into the mattress too far, this will often times cause them to roll on their side which if not monitored could cause them to choke on the padding.

It is usually recommended that the mattress should have a flat, firm surface. Choosing one that is too soft can create depressions which increases the risk of suffocation. If you press the center of the mattress, it should snap back readily without having to conform to the shape of your hand.

Cushioning Layers

This is the layer above the coils in the crib mattress. It is usually made of cotton, foam or polyester. The foam and cotton usually add to the price as they are a sign of quality. Ones made of polyester are not advisable because they have a tendency to form pockets. It is always important to look at the quality when working on a tight budget.

Border Rods

Never purchase an innerspring mattress that doesn’t have border rods. They are usually fitted around the perimeter of the top and bottom. Border rods provide a strong side and edge support that prevents sagging when your baby walks or stands near the edge. It guarantees durability and extra firmness for the crib mattress.

Getting the Right Sheet

The last thing you need to always keep an eye on are the crib sheets, whenever there are sheets on the bed make sure they are tight against the mattress and they have straps holding them in place.




How a Crib Mattress Should Fit

Though crib mattresses are available in standard sizes, parents shopping around for crib mattresses are often still confused when it comes to the type and size of crib mattress that is going to be used in the crib.

Learning to identify the features of a proper fitting crib mattress can help parents to make the right choice while ensuring the highest level of safety for the infant.

Some of the things that parents should consider when finding the right fit for the crib mattress include:

Crib Mattresses Should Meet Crib Frame with No Gaps

Gaps between the crib mattress and the crib that has been chosen for the infant are one of the most dangerous risks that are posed to infants sleeping in the mattress. Gaps between the mattresses can allow the infant to become lodged between the crib and mattress, endangering the infant that is unable to roll over or move themselves from the crevice.

Crib Mattresses Should be at the Right Level

When building the crib, parents should ensure that the infant is not in danger of falling out of the crib. There are often three levels for parents to choose from when building the crib and depending on the depth of the crib mattress, parents may have to adjust the crib accordingly.

Parents can use the higher setting for infants that are unable to roll over or crawl on their own, but move the crib mattress down when the infant reaches these milestones. Finally, once the infant is able to stand on their own the parent should adjust the crib down even further to reduce the chance of the infant standing, falling or even climbing out of the crib and endangering themselves.

The Crib Mattress Should Not Sag at the Edges

Choosing reinforced crib mattresses throughout the exterior edges of the mattress can reduce the sagging that can occur that can be potentially dangerous for the infant sleeping in the crib. Choose a reinforced crib mattress to ensure that the child is going to remain safe, from leading brands providing quality without breakdown of support over time.

How to Clean a Crib Mattress

Crib mattresses for infants and toddlers require a good regular cleaning. From being slept on to being subject to diaper leaks and bottles in the crib, there are many ways that the crib mattress can become soiled.

Cleaning the crib mattress can keep it healthy and safe for the child that is sleeping in the crib and can ensure that the parent is going to be able to use the crib mattress for more than one child. Most parents though, are unsure of how the crib mattress can be cleaned – and therefore avoid the chore.

The method used to clean the crib mattress will depend on the type of mattress that has been chosen for the infant. Crib mattresses that are created with a water-resistant layer throughout the exterior of the crib are often able to clean by simply wiping the surface of the mattress. Other types of mattresses that are created with plush exteriors may require the mattress to be cleaned with a steam or upholstery cleaner and allowed to dry.

While cleaning the crib mattress, especially while cleaning organic crib mattresses, it’s important to avoid using harsh chemical cleaners on the mattresses. These harsh chemical cleaners can leave a residue on the crib mattress that may come in contact with the skin of the infant or toddler and become absorbed, causing a potential reaction.

Using a crib mattress cover can be an effective way to reduce the need to clean the crib mattress as often. The crib mattress cover is going to protect against dust, and dirt, as well as protecting the crib mattress from being soiled – extending the life of the crib mattress. Crib mattress covers can often be easily removed from the crib, tossed into the washer, and replaced on the crib. This way, parents can save time while ensuring that the crib is going to remain clean and can be used for multiple children.

Keeping the crib mattress clean can prevent dirt and grime from forming on the crib mattress and even prevent dust mites and other allergens and irritants from becoming lodged on the surface of the crib mattress.






Choosing a crib mattress for your baby or toddler can be very tricky if you lack an idea of what to look for in the marketplace. Some mattresses are particularly designed to have ultimate cushioning in order to support the delicate spines and necks of newly born babies. Others are more tailored to prevent eczema or asthma.

That being said, you really have to go beyond any crib mattress reviews and star ratings when looking for the right product for your little angle. This information will only guide you and give you partial reassurance when making the right decision.

Also bear in mind that price tag isn’t your quality gauge as well. Inexpensive mattresses don’t mean it has inferior quality. Many parents out there are on a tight budget and will opt for less expensive brands. The right crib mattress for your baby should base on your own personal preference and circumstances.

Remember, we are only here to guide you with your decision, especially if you’re a first-time mom or mom-to-be. All of the recommendations above are available in Amazon, since it is the most convenient and the best place to buy a mattress. 

Your baby’s sleep is so important for their growth and development, therefore do not rush into buying the first crib mattress you encounter. You can always get the best deal without having to sacrifice quality.
