Why Should You Choose Your Crib Mattress Carefully

Remember, your baby is a delicate being that still hasn't fully grown yet. This means that they are more likely to become inflicted by bacteria, mold, and other contaminants that can injure them.

Statistically, SIDS was responsible for .05% of the deaths of 1,000 live babies in the US during 2005. SIDS stands for Sudden Infant Death Syndrome and is often caused due to the mattress choice of the parent.

This means that you have to find the right crib mattress for your baby. Here's a rule of thumb, get a mattress that's firm enough to prevent your baby from sinking in. Most SIDS related deaths occur because the mattress is too soft. Your baby will become engulfed by the soft material and suffocate.

That's why you need to take your crib mattress into deep consideration. Understanding the specs of your mattress will ensure that you find the right one according to your baby's need. Make a list of the specific features your infant needs to make a conscious buying decision.

On What To Pay Attention When Choosing Your Crib Mattress

Here are the most important specs you should consider when buying your first crib mattress:


The material is the most important part of your crib mattress. Buying low quality materials will result in uncomfortable sleeping, bug bites, and potentially cause SIDS if you’re not careful. 


Let's face it; water is going to spill on your mattress. Whether it's your baby dropping the bottle by accident or an accidental spill on your part, you need to get a mattress that's waterproof. Having one ensures that you won't have to spend hours cleaning up the mattress.

Safety 1st Heavenly Dreams Crib Mattress Review

Most waterproof models consist of a polyurethane of vinyl covering. Polyurethane is more expensive but is more stain resistant than vinyl. Vinyl contains phthalates that makeup 30%-40% of its weight. Phthalates cause negative reactions such as:

  • Cancer
  • Liver or kidney damage
  • Asthma
  • Reproductive Harm

Based on that fact, it is best to opt for a polyurethane covering. It's great at keeping moisture out of the mattress and is better at handling stains. Doing this will give you a reliable mattress that can be easily wiped off within seconds.


On some cases, our children are more likely to gain allergic reactions during their early growth stage. Because of this, you need to get a mattress that's hypoallergenic. Hypoallergenic mattresses are guaranteed to eliminate the amount of allergic reactions and provides the highest level of sleep protections.

Baby sleeping on a mattress.

If possible, you should get a mattress that's made of 100% organic materials. Here's a list of the organic materials for your child:

  • Latex
  • Cotton
  • Wool

Each of these materials is cultivated without pesticides and are made during a chemical-free process.

For further assurance, make sure that the mattress has a Greensgaurd Gold Seal. This seal is only given out to mattresses that are toxin-free and are guaranteed to provide the maximum comfort for your baby.


Besides the material, the firmness is another important factor you need to consider. A mattress that's too firm will result in your baby accidentally falling off the bed. Soft mattresses are just as dangerous; your baby can accidentally suffocate when resting in one of them.

To determine the best mattress setting, we suggest that you conduct the bowling ball test. Start by dropping the bowling ball on the bed. If the ball sticks to the surface, then the material is too soft for your baby.

An extra firm bed will cause for the bowling ball to bounce off the bed. This is also not a good bed for your baby. The best mattress will bounce the ball for a few times and keep it above its surface. Make sure you test the firmness of the crib mattress before purchasing it.

Is It Cover Machine Washable

There will be times when your baby makes a mess in their crib. Based on that knowledge you need a mattress that's cover machine washable. This feature allows you to easily place the mattress inside the washing machine and spend less time cleaning it.

You'll also need to know how often you should clean your baby's bedding materials. For bed covers, you should clean them once a month. Here is a quick guide to help you fully clean your mattress:

  • Use the brush attachment of a vacuum to remove the dirt from the mattress. Turn the mattress to the other side and continue to brush dirt particles off of it.
  • Create a solution using warm water and bleach free laundry detergent. For every 5 cups of water, you should have 1 tbsp of detergent.
  • ​Dip a sponge or a clean cloth inside the solution. Then start scrubbing the mattress from one side to the other. Make sure not to oversaturate the mattress as it will cause mold to grow inside of it.
  • ​Place towels in your area and begin to clean the other side of your mattress. Pay attention to any stains that might show up.
  • Take the mattress outside and allow the sunlight to dry it. If rain is apparent, then place the mattress in a dry area with good airflow. Having a fan helps speed up the drying process.
  • Add baking soda to the dry mattress. The baking soda will remove any extra odors present on the mattress.


Getting the right mattress size is essential as your baby's limbs can accidentally get caught within the ends and the gaps at the sides. The mattress should not have a gap any longer than 3 cm along the edge.

Doing this allows your baby to sleep properly. Check the dimensions of your mattress to see if it fits the measurements of the crib. If the mattress is too small or too large, discard it for one that will fit the bed with no issues.
