From the moment we unboxed the Newton Baby Ultra-Breathable Crib Mattress, it was clear this wasn’t an ordinary mattress. The core, made of a unique food-grade polymer called Wovenaire, looks like a web of tangled spaghetti and is 90% air. This isn’t a gimmick; it’s the key to its incredible breathability. We performed the “face test” immediately, pressing our faces firmly into the mattress, and could breathe without any obstruction. This feature alone is a game-changer for parents of babies who love to sleep on their tummies. Our findings are strongly backed by users, with one parent of a “face sleeper” calling it a lifesaver that finally allowed them to sleep soundly. The mattress provides excellent firm support, fitting perfectly snugly in our standard crib with no dangerous gaps. At just 11 pounds, it’s also wonderfully lightweight, making late-night sheet changes much less of a chore. The other standout feature we loved is its complete washability. The cover zips off for the machine, and the core itself can be washed down in the shower. This is a huge advantage for dealing with inevitable accidents and keeping the sleep environment free of allergens. While a few users have reported a temporary “sour” smell upon opening, we did not experience this with our test unit, which was odorless right out of the box.

The Graco Crib & Toddler Mattress is a testament to the fact that you don’t have to break the bank to get a safe, high-quality mattress. As soon as we unboxed it, we were impressed by the array of certifications it boasts for its price, including GREENGUARD Gold, CertiPUR-US, and OEKO-TEX for the cover. This mattress arrived compressed in a box, and as recommended, we allowed it a full 48 hours to expand. It puffed up perfectly to its intended height with no noticeable smell. The firmness is spot on for an infant—supportive and flat without being rock-hard. We found the included waterproof cover to be soft and, importantly, quiet. There’s none of the crinkly, plastic-like noise that can plague other waterproof mattresses. Many users echoed our experience, noting how well their babies sleep on it and how perfectly it fits a standard crib. Its lightweight foam core, weighing only 7 pounds, makes it incredibly easy to lift for sheet changes. The zip-off cover held up perfectly in the wash on a delicate cycle. For parents seeking a reliable, certified-safe, and comfortable mattress that offers tremendous value, the Graco is an easy recommendation.
Advantages
- Excellent value for a GREENGUARD Gold certified mattress
- Soft, quiet, and waterproof machine-washable cover

The Milliard Dual Stage Crib Mattress Waterproof Cover is a brilliantly designed mattress that truly grows with your child. We were particularly impressed with its “Flip Dual Stage System.” One side provides the firm, supportive base recommended for infants, while the other side features a layer of high-quality memory foam for toddler comfort. We tested both sides and found a distinct and appropriate difference in feel. The infant side is solid and safe, and the toddler side has a plush, contouring feel that older children will appreciate. The CertiPUR-US certified foam expanded quickly and evenly within a day, and we detected no strong odors, a sentiment shared by most users. The bamboo and polyester blend cover is exceptionally soft and has a completely waterproof barrier that performed well in our spill tests. We also appreciated the thoughtful non-slip grip dots on the bottom of the cover to keep it in place. Many users have noted a significant improvement in their toddler’s sleep after switching to this mattress, which speaks to the comfort of the memory foam side. It fit our test crib perfectly with no gaps. For parents who want a single mattress to last from day one through the toddler years, this is an excellent and cost-effective choice.
Key Benefits
- Dual-sided design offers longevity from infant to toddler stages
- Comfortable memory foam on the toddler side
- Soft, waterproof, and machine-washable bamboo blend cover
- CertiPUR-US certified foam with no strong off-gassing
Limitations
- Some users noted the zipper on the cover could be more durable
- Memory foam is not suitable for infants under one year, requiring careful use

- IDEAL FOR INFANTS AND TODDLERS: Premium sustainably sourced firm fiber core made from upcycled plastic bottles for a healthier, longer...
The Delta Children Serta Perfect Start Dual Sided Crib Mattress offers a step up in thickness, measuring a full 6 inches. This extra depth gives it a more substantial, premium feel compared to some thinner models. Right away, we noticed its excellent firmness, which is crucial for newborn safety. The GREENGUARD Gold certification provides peace of mind regarding air quality. Like other mattresses in this line, it has a waterproof vinyl cover that makes it exceptionally easy to wipe clean after spills or accidents. We found the mattress to be surprisingly lightweight for its thickness, which is a bonus for parents during sheet changes. It fit our standard crib perfectly, with the square corners leaving no gaps. The dual-sided feature is a key selling point, though, like some users, we found it difficult to distinguish between the infant and toddler sides by feel alone. The manufacturer clarifies that the side with the product tag is the firmer infant side. While the overall construction is solid, we did see several user reports of the vinyl cover tearing over time, sometimes within a few months. This seems to be a recurring issue with this type of cover and is something potential buyers should consider.
Advantages
- 6-inch thickness provides a substantial feel
- GREENGUARD Gold certified and non-toxic construction
- Waterproof and easy to wipe clean
- Firm support suitable for newborns
Drawbacks
- Difficult to tell the infant and toddler sides apart
- Reports of the vinyl cover tearing raise durability concerns
#7 Letmxiu Premium Crib & Toddler Mattress – Ideal for: A Plush, Fabric-Covered Feel

- 【Support】The crib mattress Made of soft and strong high grade memory foam. It has good support and stability when baby rolls over...
The Letmxiu Premium Crib & Toddler Mattress distinguishes itself with a soft, knitted fabric cover that feels much cozier than a typical vinyl surface. Upon unboxing from its vacuum-sealed packaging, we let it expand for the recommended 72 hours. While it didn’t quite reach the full 5-inch advertised thickness in all areas, it settled into a comfortable and acceptably firm shape. The high-grade memory foam core provides good support, and we found the firmness level to be appropriate for safe sleep. The fleece surface is genuinely soft to the touch and silent when the baby moves. Our test unit was odorless and hypoallergenic, which is a huge plus. We were impressed by how well it fit in our crib, with its slightly oversized dimensions ensuring no gaps whatsoever. A notable drawback is that the fabric cover is not waterproof, which we consider a significant oversight for a crib mattress. Parents will absolutely need to purchase a separate waterproof protector to go over it. Despite this, for those who prioritize a soft, non-plastic sleep surface and don’t mind adding a protector, this mattress offers excellent comfort and value.
Key Benefits
- Very soft and quiet knitted fabric cover
- Firm memory foam core provides good support
- Affordable price point
- Hypoallergenic and non-toxic materials
Limitations
- The cover is not waterproof
- May not expand to the full advertised thickness for all users
#8 Newton Baby Waterproof Crib Mattress Ultra-Breathable – Ideal for: The Best of Both Worlds: Breathability and Waterproofing
The Newton Baby Waterproof Crib Mattress Ultra-Breathable takes everything we love about the original Newton and adds a crucial feature for the toddler years: a waterproof barrier. This mattress retains the same revolutionary Wovenaire core, which we confirmed is 100% breathable and offers unparalleled peace of mind for parents of stomach-sleepers. The key difference is the cover. This version has a dual-sided design: one side offers maximum breathability for infants, while the other side, intended for toddlers, has a waterproof layer to protect the core from accidents. This makes it an excellent long-term investment that seamlessly transitions into potty-training years. The entire mattress is still 100% washable, a feature we can’t praise enough for maintaining a hygienic sleep space. At 15 pounds, it’s slightly heavier than the original but still manageable. It fits a standard crib perfectly, providing that essential snugness. While some users have questioned the effectiveness of the waterproofing, our spill tests on the toddler side held up well, preventing liquid from reaching the core. For parents who want the signature Newton breathability for infancy and practical waterproofing for toddlerhood, this is the ultimate all-in-one solution.
What We Like
- Combines industry-leading breathability with a waterproof toddler side
- Completely washable cover and core
- Excellent 2-stage design for long-term use
- GREENGUARD Gold certified and non-toxic
What We Didn’t Like
- Highest price point in our guide
- A few users reported that the mattress fit too snugly, causing the cover to pucker
#9 Dourxi Dual Sided Crib Mattress Memory Foam – Ideal for: Gel-Infused Memory Foam Comfort for Toddlers
The Dourxi Dual Sided Crib Mattress Memory Foam feels like a luxury adult mattress shrunk down for a crib. Its triple-layer design, featuring gel-infused memory foam, is impressive. Upon unboxing, we were pleased that there was no chemical smell, and it expanded to its full 6-inch thickness within the 72-hour window. The dual-sided design offers a noticeable difference in feel: the infant side is appropriately firm and supportive, while the toddler side has a plush, contouring quality from the memory foam that we found very comfortable. The gel infusion is designed to help regulate temperature, and the mattress did feel cool to the touch. The removable cotton-blend cover is soft and washable, a feature we always appreciate. We did encounter some user reviews citing sizing inconsistencies, with some finding it too short for their crib. However, our test model measured correctly and fit our standard crib perfectly with no unsafe gaps. The customer service also appears to be responsive in addressing these issues. For parents who want to provide their toddler with a premium memory foam experience after their first year, this mattress is an excellent option that offers high-end features at a reasonable price.
Pros
- Plush and comfortable gel-infused memory foam for toddlers
- Excellent dual-sided design with distinct firmness levels
- CertiPUR-US certified foam with no off-gassing
- Thick 6-inch profile and soft, washable cover
Cons
- Some users reported inconsistent sizing leading to gaps in the crib
- Takes up to 72 hours to fully expand
#10 SEALY BABY Flex Cool 2 Stage Breathable Crib Mattress – Ideal for: Traditional Innerspring Support
For parents who prefer the traditional feel and support of an innerspring mattress, the SEALY BABY Flex Cool 2 Stage Breathable Crib Mattress is a solid choice. With 204 premium steel coils, it provides a very firm and responsive surface. We were impressed by the robust edge support from the steel frame, which prevents sagging at the sides when a child stands on it. The dual-firmness design is well-executed, with a noticeably firmer side for infants and a slightly more cushioned side for toddlers. The cotton cover feels soft and breathable, and the PVC-free waterproof barrier beneath it worked effectively in our tests. We also value its GREENGUARD Gold certification, ensuring low chemical emissions. However, we must address the significant number of user complaints regarding quality control. Reports of mattresses arriving dirty, with poor stitching, or developing noisy, popping springs after a few months are too common to ignore. While our test unit did not have these defects, the pattern suggests potential inconsistencies in manufacturing. If you receive a well-made unit, it’s a supportive and durable mattress, but buyers should inspect it carefully upon arrival.
Advantages
- Strong and supportive 204-coil innerspring system
- Excellent edge support prevents sagging
- GREENGUARD Gold certified with a breathable cotton cover
- Effective waterproof barrier
Drawbacks
- Numerous user complaints about quality control and durability issues
- Springs can become noisy over time
The Ultimate Buyer’s Guide: How to Choose The Right Product for You
Key Factors to Consider
- Firmness and Support: The American Academy of Pediatrics (AAP) recommends a firm, flat surface for infants to reduce the risk of SIDS. A mattress that is too soft can conform to a baby’s head, creating a suffocation hazard. Many mattresses are dual-sided, offering a very firm side for infants and a slightly softer, more comfortable side for toddlers.
- Fit and Size: A crib mattress must fit snugly inside the crib. The standard is that there should be no more than two fingers of space between the mattress and the crib frame. Any larger gap can pose an entrapment risk. Always check the dimensions of both your crib and the mattress.
- Material and Breathability: Crib mattresses come in various materials, including foam, innerspring, and innovative polymer cores like the one in the Newton. Foam is lightweight and affordable, while innersprings are often more durable. For ultimate peace of mind, models designed for maximum breathability can help reduce the risk of suffocation and overheating.
- Certifications: Look for certifications like GREENGUARD Gold, which tests for low chemical emissions and ensures healthier indoor air quality. CertiPUR-US for foam mattresses guarantees they are made without certain harmful chemicals. These certifications provide third-party verification of safety claims.
- Waterproofing and Washability: Accidents are inevitable. A waterproof cover or barrier is essential for protecting the mattress core from mold and mildew. Some mattresses go a step further, offering fully washable covers and even washable cores, which is the gold standard for hygiene.
Frequently Asked Questions
What certifications prove a crib mattress is truly organic?
The most stringent and respected certification for organic products is the Global Organic Textile Standard (GOTS). For a mattress to be GOTS-certified, it must contain at least 95% certified organic fibers and meet strict environmental and social criteria throughout the entire supply chain. For products containing latex, look for the Global Organic Latex Standard (GOLS). These are the gold standards that verify a product is truly organic, not just “natural” or “eco-friendly.”
Are organic crib mattresses worth the higher price point?
This is a personal decision. Organic crib mattresses are made without the use of pesticides, certain chemicals, and flame retardants often found in conventional mattresses. This can lead to lower VOC (Volatile Organic Compound) emissions and a healthier sleep environment. For parents who prioritize a nursery free from synthetic materials and potential allergens, the peace of mind offered by a certified organic mattress can be well worth the investment.
What natural materials are commonly used in organic crib mattresses?
Common materials include organic cotton for covers and padding, organic wool which acts as a natural flame retardant and temperature regulator, and organic coconut coir (fiber from coconut husks) for firm support. Organic latex is also used for a supportive and durable core. These materials are chosen for their sustainability, breathability, and lack of synthetic chemicals.
Do organic crib mattresses off-gas less than conventional ones?
Yes, significantly so. Off-gassing is the release of VOCs from synthetic materials, such as polyurethane foam and vinyl covers. Certified organic mattresses, made from natural materials without chemical treatments, glues, or flame retardants, produce little to no harmful off-gassing, contributing to better indoor air quality in the nursery.
What’s the difference between organic and natural crib mattresses?
The term “natural” is not regulated and can be used loosely for marketing. A mattress might be made with natural latex but still use chemical glues or a synthetic cover. “Organic,” on the other hand, refers to materials grown and processed according to strict federal guidelines, verified by third-party certifications like GOTS and GOLS. Always look for the certification, not just the word “natural.”
How do I properly clean and care for an organic crib mattress?
Always follow the manufacturer’s instructions. Generally, you should use a waterproof mattress protector to guard against spills. For spot cleaning, use a mild solution of water and gentle soap. Avoid harsh chemical cleaners. Regularly airing out the mattress can also help keep it fresh. Some innovative non-organic mattresses, like the Newton, are designed to be fully washed, which is a unique advantage for hygiene.
Can organic crib mattresses also be waterproof?
Yes. Many organic mattresses achieve waterproofing by using a food-grade polyethylene layer or a tightly woven organic cotton fabric that is highly water-resistant. This avoids the use of vinyl/PVC and phthalates found in some conventional waterproof covers. Alternatively, many parents opt for a separate organic waterproof mattress protector pad.
Conclusion: Our Final Recommendation
After thorough testing and careful consideration, we stand firmly by our top pick: the Newton Baby Ultra-Breathable Crib Mattress. While not certified organic in the traditional sense, its non-toxic, food-grade polymer construction achieves the same goal of a safe, chemical-free sleep environment, while adding two revolutionary benefits. The first is its proven breathability. Being able to physically test and confirm that a baby can breathe directly through the mattress provides a level of reassurance that is priceless for any parent, especially during those first few months when a baby begins to roll over. The second is its 100% washability. The ability to wash the entire mattress core eliminates concerns about dust mites, allergens, and deep-set messes. It’s an investment in safety, hygiene, and ultimately, peace of mind, making it the best and most innovative crib mattress available today.
