  • Expensive
  • Washable cover and core
  • Long sleep trial
  • Very breathable
  • Liquids will drip to the floor

The Newton Baby Crib Mattress packs unique features that really set it apart from the majority of crib mattresses in the market. Unlike conventional mattresses, this product is not made of foam. The structure of the mattress core is made of proprietary food-grade polymer threads that have been pressed together to form a solid block.

One of the advantages of this special engineering is breathability. The way the polymer threads are pressed together leaves space inside which promotes excellent airflow. This allows air to easily pass through from one side to the other, lessening the risk of suffocation and improving temperature regulation.

In the case of bedwetting, the core will quickly let liquids gush through to exit the underside. While this will keep the mattress from being soggy, it may cause staining on your floor. When it comes to maintenance, this top-rated crib mattress is the only product in its class where both the cover and core can be washed.

The pressure distribution of the Newton Baby Crib Mattress is also ideal for comfort and support. Its comfort layer allows children to sleep with proper posture while keeping them comfy all night long.

The Newton Baby Crib Mattress comes with a limited lifetime warranty and starts at $249.99 for the original, all the way to $349.99 for the waterproof version. If you sign up for their mailing list, they’ll slash $25 off from your purchase. Newton Baby Crib Mattresses also come with a 100-night trial.

In terms of hygiene, the Graco Premium Foam Crib and Toddler Mattress is hypoallergenic. It does a good job of preventing harmful microbes from settling in, keeping nasty germs, and allergens away from your child.

There are 3 variants to Naturepedic’s Organic Baby Crib Mattresses: Classic, Breathable, and Breathable Ultra. These variants have slight differences in features but are similar in build and quality.

This particular mattress is Nook’s answer for those looking for a comfortable and highly durable two-stage crib mattress that is purely organic and eco-friendly.

Its hypoallergenic features make it moisture and mold resistant which keeps away mildew and similar allergens. This means that the mattress maintains impeccable hygiene at all times.

The toddler side is topped with a layer of natural rubber latex which provides ideal support for a growing baby. Covering the entire mattress is an organic wool fire barrier that is flame resistant. The Nook Organic Pure Mattress has been awarded a Gold Certification from Greenguard.

Best Hypoallergenic Crib Mattress

  • Good heat displacement
  • No trial
  • Toddler side may be too soft for some

Colgate has over a dozen crib mattresses in their lineup, and for this article, we will review the Eco Classica III which comes from the Eco Classica collection. The Eco Classica III is a two-in-one crib mattress that can be used for both infants and toddlers.

All mattresses in the Eco Classica collection have been issued with a Gold Certification by Greenguard. This means they have very low chemical emissions, making them eco-friendly and safe for users. The 6-inch foam is made from sustainable plant oils, while the cotton cover is naturally fire-resistant.

Colgate Eco Classica III’s hypoallergenic properties keep microbes and allergens away. The naturally breathable fabric also does a good job displacing heat which caters to hot sleepers.

As for firmness, the infant side is stiff enough to give the necessary support layer for sleeping babies. The same firmness is also good for babies needing a stable yet soft surface to practice crawling and walking. The toddler side is much softer which offers the bouncier comfort that most toddlers prefer, although might be too bouncy for some. As for edge support, the Eco Classica III does not sink anywhere, reducing the risk of children falling off.

The Colgate Eco Classica III fits all US standard sized cribs and is priced at $219.99. Every product comes with a limited lifetime warranty. Customers are entitled to discounts when using applicable coupons.

Best Waterproof Crib Mattress

  • Contains no harmful substances
  • Easy maintenance
  • Good breathability
  • Expensive
  • A little heavy

For Lullaby Earth, the focus of this article will be the Breeze Air Breathable Two Stage Crib Mattress. This product is specially designed with safety and comfort in mind and will do a good job for babies from infancy up to toddlerhood.

One of the unique features of Lullaby Earth is its approach to breathability. The cover of the Breeze Air Breathable Two Stage Crib Mattress is made to be a 3-dimensional structure that lets air pass freely through the fabric. This very efficient airflow is great for temperature management and is beneficial for children who sweat during sleep. Should the baby turn over to lay flat, they can still easily breathe through the fabric which reduces the risk of SIDS.

The breathable cover is also very easy to maintain. It has a waterproof backing that protects the mattress from any spills or accidents. When it’s time to clean the cover, just toss it in the washer, dry, and it’s ready to use again. The cover is easy to remove but the mattress can be a little bit heavy to move around.

The Lullaby Earth Breeze Air Breathable Two Stage Crib Mattress does not contain phthalates, formaldehyde, PFCs, and other similar substances known to cause harm to both health and the environment. It uses no fire retardants but is still fire safety compliant.

The Lullaby Earth Breeze Air Breathable Two Stage Crib Mattress is priced at $259. It comes with free shipping, a limited lifetime warranty, and a 30-night sleep trial.

Types of Crib Mattresses

Crib mattresses come in many forms. And if you’re on the hunt for one but are still overwhelmed by the huge plethora of product variations, getting an idea about the different types of crib mattresses should help you slim down your choices.

  • Organic Crib Mattress

Organic Crib Mattresses are those that are made from naturally sourced materials. These Crib Mattresses do not contain synthetics and also do not use harmful chemicals during production.

  • Eco-Friendly Crib Mattress

Eco-Friendly Mattresses are those that are made from renewable materials. They may also contain synthetics and some chemicals, but only in very minimal quantities and safe levels.

  • Coil Crib Mattress

Coil crib mattresses are those that use innerspring coils inside. These coils hold support for the mattress and make them bouncy. There are many types of coils, with the most common being the 150-coil and 252-coil. These gauges determine the strength and stiffness of the mattress.

  • Foam Crib Mattress

Foam crib mattresses are made purely of foam. As opposed to coil crib mattresses that use springs, mattresses with memory foam and poly foams use fabrics and special weaving techniques to provide the structure and bounce of the mattresses.

  • Double-Sided Mattresses

Double-sided mattresses are those that have both a soft side and a stiff side. These different sides are intended to accommodate both infants and toddlers, with the stiffer side for infants and the softer for toddlers.

How to Choose the Right Crib Mattress

With many kinds of crib mattresses to choose from, getting the right one is a bit daunting. In deciding which product to bring home, it’s best to consider some important factors to make sure that you’re getting the best crib mattress that would perfectly suit your child’s needs.

Here are the common things that you should be looking at:

✔ Features — not all mattresses offer the same features so make sure to check for the important ones. Is it waterproof or water-resistant? Is it breathable? How easy is it to clean and maintain? What is the sleep material made of?

✔ Size Availability — most crib mattresses are designed to fit standard US sized cribs. What usually varies is the thickness. Certain brands may not offer mattresses with the thickness that you need.

✔ Firmness — how firm do you want the mattress to be? A firm mattress will give good weight distribution and should also prevent lumpiness issues over time. While a firm mattress provides good skeletal support, too firm may not be comfortable which would affect your child’s quality of sleep.

✔ New or used — you can always save up on cash if you buy used. However, there are many benefits to buying brand new. One is that you can be sure that it’s clean and pristine. Another is that most manufacturers only grant warranty for original buyers.

✔ Cover options — some crib mattresses come with their own covers, while some do not. Most of the time, covers or mattress protectors that are bundled with the mattresses have special features specially made to enhance and maximize the user experience.

✔ Sleep trial — no matter how good it looks on paper whether you’re at the specs sheet or crib mattress reviews, actual use may be very different. Take advantage of sleep trials to make sure you’re getting the promised experience.

✔ Budget — at the end of the day, it all comes down to budget. Review all the conditions and options, then balance it out with how much you’re willing to spend. Choose the one that satisfies both your needs and your wallet.

Key Takeouts

Every parent knows all too well that when your babies sleep well, so would you. While many things can affect babies’ sleep quality, having a good crib mattress certainly helps. There are many top crib mattress brands out there, each with their products. Choosing the right one is not only beneficial for getting great sleep, but also for supporting the development of your baby.

FAQ

What is the standard size mattress for a crib?

Crib mattresses that follow US standard cribs would have a width of 28” and a length of 52”. Thickness may vary depending on the brand which can typically be between 4” to 6”.

Will jumping on the mattress ruin it?

Good mattresses are built tough which should guarantee durability. They have been designed with the consideration that kids would want to jump and play around the mattress. Deterioration from normal use should not be an issue.

What’s the best crib mattress to buy?

The best crib mattress will always be subjective as this all depends on each consumer’s needs. Knowing what you want and what your preferences are will help narrow down choices to arrive at the product that’s best for you. If you’re looking for an eco-friendly mattress, then the Naturepedic Organic Crib Mattress and the Nook Crib Mattress are among your best bets. If breathability is your primary consideration, Newton Baby Crib Mattress’s unique core structure will provide you with unparalleled airflow.
