The Best Crib Mattresses


If you still can’t decide on which mattress to buy for your baby, we’re here to help! Since babies are usually spending their first months in cribs, you have to consider size, comfort, and safety before anything else.

To keep you from dealing with hundreds of options in stores, we’re recommending some of the best crib mattresses money can buy.

Our Pick: Milliard Hypoallergenic Baby Crib Mattress

If you think softer mattresses are more comfortable, think again. Babies should use firmer mattresses to avoid sinking into the foam, reducing the risks of sudden infant death syndrome (SIDS). Good thing that Milliard Hypoallergenic Baby Crib Mattress has the right level of firmness to maintain comfort.

As a plus for parents, this crib mattress is easy to maintain as well. It has a reinforced encasement to remain waterproof no matter where the moisture is. Don’t worry about breathability; the bottom part promotes total ventilation to avoid trapping heat and air.

Regarding safety, the backside uses flame-resistant materials. In addition, it contains zero chemicals to prevent skin irritation.

When it comes to durability, this option is hard to beat. It has a high level of density to stop wear and tear. It can keep its shape for a lifetime.

Runner Up: Moonlight Slumber Dual Crib Mattress

Throughout the baby years of your child, Moonlight Slumber Dual Crib Mattress will always be there because of its unique design. From the newborn stage up to the toddler phase, it can keep your baby comfortable 24/7. It uses a special dual system wherein one side is firmer for infants while the softer layer is made for toddlers.

More about the nontoxic features of this product, it doesn’t contain flame-retardant chemicals. It only has a few volatile organic compounds (VOCs) to reduce its effect on indoor air.

Just like the first option, this crib mattress is also waterproof. Aside from the safe medical-grade quality of the fabric, its stretchiness will remain for years. It is very durable, thanks to its seams sewn really tight.

Another benefit of the extra-tight seams is resistance to dust mites and bed bugs. No wonder this mattress is hypoallergenic.

Also Great: Serta Perfect Start Natural Crib Mattress

With its fiber core made of hypoallergenic polyester, Serta Perfect Start Natural Crib Mattress isn’t just firm – it’s super-lightweight, too! That promotes convenience in bringing the mattress around the house or changing its cover.

Speaking of the cover, it is made of vinyl to stay waterproof. It won’t retain stains and absorb moisture.

As you can see, the edges or corners of the foam are defined. This results in a more secure fit when inside the crib. No matter how much your baby moves, the mattress won’t budge.

How to Choose the Best Crib Mattresses

We considered several factors before selecting the best crib mattresses to introduce to you. Based on expert tips from a certified pediatrician, here are the things we thought about before completing the products list:

  • Size

    The length and width of a crib mattress should not be smaller than 51.25 inches and 27.25 inches. Gaps on the sides can be fatal. Your baby might get stuck, which may lead to the worst-case scenario – suffocation.

    Just to be on the safe side, you must learn how to properly measure the crib. Luckily for you, all you need is the measurement of its length and width. Use a flexible tape measure for more accurate numbers.

    As for the mattress’s height, it shouldn’t be thicker than six inches. Sinking into the foam can cause suffocation.

  • Safety

    While thicker crib mattresses aren’t recommended, having an extra-thick cover isn’t too bad. Thicker covers are usually guaranteed to be durable and waterproof. Holes and tears can lose the hypoallergenic properties of the cover due to the possibility of bed bugs and dust mites.

    More importantly, the mattress should be well-ventilated. It must use an advanced system or technology that can boost airflow. This is crucial to prevent suffocation.

    Lastly, you can’t go wrong with organic mattresses. Plant-based materials are less likely to contain chemicals like flame retardants.
