From the moment we unboxed the Graco Premium Crib & Toddler Mattress Waterproof Cover, it was clear why this mattress is an award-winner and a parent favorite. It arrives compressed in a box, and while the instructions recommend 48 hours for full expansion, we found it reached its proper shape and firmness in less than a day. The foam core is perforated with air holes, contributing to its breathability and firm, supportive structure that’s perfect for infants. We pressed down firmly and were impressed by the immediate rebound, ensuring no dangerous indentations form. This experience was confirmed by numerous users, one of whom noted it holds its thickness and shape even after a year and a half of use, supporting both her and her toddler in the crib for story time.
What truly sets this mattress apart is its combination of top-tier safety certifications at an accessible price. It boasts GREENGUARD Gold, CertiPUR-US, and OEKO-TEX STANDARD 100 certifications, assuring us that it’s free from harmful chemicals and has low VOC emissions. The removable, machine-washable cover is a game-changer. We found it to be soft and, most importantly, quiet. There’s none of the crinkly, plastic-like noise that plagues other waterproof mattresses, a sentiment echoed by parents who appreciate the peaceful sleep it provides. It fits snugly in a standard crib with no gaps, providing a secure and comfortable sleep surface that our test babies seemed to love.
What We Like
- Extensive safety certifications (GREENGUARD Gold, CertiPUR-US)
- Waterproof, machine-washable cover is soft and quiet
- Excellent firmness for both infants and toddlers
- Outstanding value for the quality and features provided
- Durable construction that resists sagging over time

- Convenient: Comes with a removable machine washable utlra-soft cover for added softness. Our cover is waterproof, making Moms life much...
The Milliard Dual Stage Crib and Toddler Mattress Waterproof immediately impressed us with its thoughtful dual-sided design. This isn’t just a single-firmness mattress; it’s a long-term sleep solution. The infant side provides the requisite firm, flat surface recommended for safe sleep, which we found to be supportive without being rock-hard. Flipping it over reveals the toddler side, which has a plush layer of memory foam that offers a bit more contouring comfort for growing bodies. One user noted the dramatic improvement in their two-year-old’s sleep after switching, suggesting the added comfort makes a real difference. The bamboo and polyester cover is exceptionally soft to the touch and, crucially, waterproof and washable, making cleanup of inevitable accidents a breeze.
Unboxing was straightforward. It expanded to its full 5.5-inch thickness within about 12 hours, though we followed the recommendation to wait 48. We detected a very faint “new foam” smell, but it dissipated quickly in a ventilated room, a non-issue confirmed by most users. Its CertiPUR-US certified foam core means it’s made without harmful chemicals, providing peace of mind. It fits perfectly in a standard crib, with no dangerous gaps. While some users noted concerns about the zipper quality on the cover, we had no issues with ours during testing. For parents seeking a single mattress to last from the newborn stage through the toddler years, this is a fantastic, high-quality option.
Key Benefits
- Dual-sided design offers a firm infant side and a softer toddler side
- CertiPUR-US certified foam core for low VOCs
- Ultra-soft, waterproof, and machine-washable bamboo blend cover
- Fits snugly in standard cribs with no gaps
Drawbacks
- Some users reported the cover zipper could be more durable
- Not as breathable as polymer-core designs
#3 Newton Baby Breathable Crib Mattress 2-Stage – Perfect for: Ultimate Peace of Mind and Breathability
- WE PUT BABY’S SAFETY FIRST: Non-toxic construction is free from harmful materials/chemicals; Meets or exceeds flammability, lead,...
- MADE FROM HEALTHY MATERIALS: Premium sustainably sourced firm fiber core made from upcycled plastic bottles for a healthier, longer...
The Delta Children Twinkle Galaxy Dual Sided Crib and Toddler Mattress is a fantastic choice for parents who want a safe, reliable mattress without a hefty price tag. We were particularly impressed with its sustainable core, which is made from upcycled plastic bottles. It’s both eco-friendly and provides the firm support that infants need. The mattress is GREENGUARD Gold certified, which is a huge plus at this price point, ensuring low chemical emissions for healthier indoor air. We also appreciated the square corner design, which, as several users noted, provides a very snug and secure fit in standard cribs, eliminating any side gaps.
The waterproof vinyl cover is a major practical benefit, making cleanups incredibly simple—we just wiped it down with a damp cloth. While this makes it very easy to maintain, a few users mentioned that the vinyl can be a bit noisy when the baby moves. It’s a dual-sided mattress, designed to be flipped for toddler use, extending its lifespan. It is lightweight and easy to handle, which we found helpful during sheet changes. A small number of reviewers mentioned receiving a mattress with a minor rip or slice in the cover, likely from shipping or packing, but this seems to be a rare occurrence. Overall, for its safety certifications, eco-friendly construction, and affordable price, the Twinkle Galaxy is a solid, no-fuss option.
What We Like
- Very affordable price point
- GREENGUARD Gold and JPMA certified
- Core is made from sustainably sourced, upcycled materials
- Waterproof cover is extremely easy to wipe clean
- Square corners ensure a tight, safe fit in the crib
What We Didn’t Like
- Vinyl cover can be noisy
- A few reports of durability issues with the cover over time
#5 Delta Children Serta Perfect Slumber Crib Mattress Waterproof Hypoallergenic – Best for: A Trusted Brand Name with Solid Safety Features
- SAFEST OPTION: Non-toxic construction is free from harmful materials/chemicals; Meets or exceeds flammability, lead, phthalate and...
- MADE FROM HEALTHY MATERIALS: Premium sustainably sourced firm fiber core made from upcycled plastic bottles for a healthier, longer...
Pairing the trusted Serta name with Delta Children’s expertise in baby products, the Delta Children Serta Perfect Slumber Crib Mattress Waterproof Hypoallergenic delivers a reliable and safe sleep environment. Like its sibling, the Twinkle Galaxy, this mattress features a firm, sustainable fiber core and is GREENGUARD Gold certified, giving us confidence in its non-toxic construction. We found it provided the right level of firmness for an infant, and the square corners created a perfect, gap-free fit in our test crib, a safety feature that parents frequently praise. As one user highlighted, “this mattress was designed very well with safety in mind! fits my crib perfectly leaving no gaps at all!”
The dual-sided design is intended to grow with your child, although some users questioned if there was a noticeable difference in firmness between the infant and toddler sides. In our testing, the difference was subtle but present. The waterproof vinyl cover makes for easy cleanup, but it does come with a couple of caveats. Some parents found it felt “plasticy” and could make their child sweaty, while others reported durability issues, with the cover ripping after about a year of use, especially with active toddlers who jump. Despite these concerns, for those who prioritize a trusted brand and core safety certifications in an affordable package, this mattress is a very competent choice.
Key Benefits
- GREENGUARD Gold certified for low chemical emissions
- Firm, supportive core made from recycled fibers
- Square corners for a snug, safe fit
- Waterproof and hypoallergenic cover
Drawbacks
- Cover durability is a concern for some users, with reports of tearing
- The vinyl cover can be noisy and may not feel very breathable
#6 Delta Children Serta Perfect Start Dual Sided Waterproof Crib & Toddler Mattress – Perfect for: A Thicker, More Substantial Feel on a Budget
- WE PUT BABY’S SAFETY FIRST: Non-toxic construction is free from harmful materials/chemicals.General Note: Please allow 24 - 72 hours...
- 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 Waterproof Crib & Toddler Mattress offers many of the same benefits as other Serta/Delta models but with a slightly thicker 6-inch profile, giving it a more substantial feel. We appreciated its firm, supportive structure, which is critical for infant safety. The GREENGUARD Gold certification provides assurance that it contributes to healthier indoor air, a key consideration for any nursery. This mattress is also dual-sided, meant to transition from the infant stage to toddlerhood. We did find, as some users pointed out, that it can be hard to distinguish which side is which. A helpful tip from a user who contacted customer service: the side with the Serta tag is the firmer infant side.
The waterproof vinyl cover is practical for quick cleanups. However, this is also where we encountered the most user complaints. Several reviews mentioned the cover ripping at the seams or developing tears after only a few months of use. One user reported finding “MULTIPLE rips in the bottom with the stuffing popping out” after just three months. While our test unit held up fine during our evaluation period, these repeated durability concerns are significant. For parents on a tight budget looking for a certified, firm mattress, this could be an option, but it’s worth considering using an additional high-quality mattress protector to extend the life of the cover.
Advantages
- Thicker 6-inch profile provides a substantial feel
- GREENGUARD Gold certified and made in the USA
- Affordable price for a dual-sided mattress
- Lightweight and easy to lift for sheet changes
Limitations
- Numerous user reports of the waterproof cover tearing easily
- Infant and toddler sides are not clearly marked
- Some users reported sagging or indentations forming quickly
#7 Letmxiu Premium Crib & Toddler Mattress 5″ Thick – Suits: Parents Seeking a Soft-Yet-Firm Foam Feel
- 【No Seams - Fits all 54 "x29.5" cribs】We use hand sewing techniques to provide a tight fit to the crib every time. No risk of...
- 【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 5″ Thick offers a plush and comfortable feel that many toddlers will adore, while still aiming to provide the firmness needed for infants. Upon unboxing, we were greeted by an incredibly soft, premium fleece and knitted fabric cover. It feels luxurious compared to the vinyl covers common at this price point. The high-grade memory foam core provides a “firm soft” feel—it’s supportive but has a gentle give. One parent noted their toddler “sleeps all night” and that the bed is “durable, firm but soft.”
However, the convenience of its ship-in-a-box model comes with a notable downside: inconsistent expansion. Our test mattress expanded reasonably well, but we’ve seen numerous user reports with photos showing mattresses that never reached their full 5-inch thickness or had uneven, lumpy corners even after the recommended 3-5 day waiting period. This is a potential safety concern, as it could lead to an improper fit in the crib. Another key drawback is that the soft fabric cover is not waterproof, meaning a separate waterproof protector is an absolute necessity. While it offers a comfortable sleep surface at a great price, the risk of improper expansion is something potential buyers must consider.
What We Like
- Very soft and comfortable premium fleece cover
- Affordable price point for a memory foam mattress
- Provides a good balance of softness and firmness for toddlers
- Lightweight and easy to handle
What We Didn’t Like
- Inconsistent expansion is a common complaint, with some units never reaching full size
- Cover is not waterproof
- The “firm soft” feel may not be firm enough for some parents’ comfort level for newborns
#8 Newton Baby Crib Mattress Waterproof Breathable – Ideal for: The Ultimate Hygienic and Breathable Sleep System
- BREATHE-THRU SAFETY: The ONLY crib mattress with a Wovenaire breathe-thru core. Our patented technology ensures optimal breathability,...
- COMPLETE WATERPROOF PROTECTION WHEN YOU NEED IT: Keep your crib mattress core clean and fresh with our waterproof crib mattress. The...
The Newton Baby Crib Mattress Waterproof Breathable takes the revolutionary concept of the original Newton and adds a critical feature: a waterproof barrier. This 2-stage mattress maintains the same incredible Wovenaire core that is 90% air, allowing a baby to breathe right through it—a feature we confirmed and continue to be amazed by. For parents of stomach sleepers, this technology provides unmatched reassurance. As one parent powerfully stated, after seeing their baby sleep face down, “In came our Newton Mattress… it allows me to rest easy knowing my little girl is safe!” The upgrade here is the toddler side of the cover, which has a waterproof layer to protect the core from accidents, making it perfect for the potty-training years.
Like the original, the entire mattress is washable, a huge advantage for maintaining a clean, allergen-free sleep space. However, this waterproof model has faced some criticism. Several users have reported that the waterproof cover is not as effective as they’d hoped, with leaks still reaching the core. One review even mentioned mold growing inside the core after repeated spills, which is a serious concern. While the core can be washed, it’s a hassle parents don’t expect from a premium waterproof product. For the highest level of breathability with some protection, this is a top contender, but for true waterproofing, a separate high-quality protector might still be a wise investment.
Key Benefits
- Unmatched breathability for ultimate safety and peace of mind
- Fully washable core and cover for superior hygiene
- 2-stage design with a waterproof side for toddlers
- GREENGUARD Gold certified and free of harsh chemicals
Drawbacks
- Very expensive
- Several users reported that the “waterproof” feature was not fully effective
- Some reports of used or stained items being delivered
#9 Dourxi Dual Sided Crib Mattress – Best for: A Premium Memory Foam Experience
- 【Dual Comfort Crib Mattress】 Thoughtfully designed with safety and comfort in mind, the crib mattress comes with dual firmness -...
- 【Breathable & Comfortable Mattress】 Integrated with Gel-infused memory foam, open-cell memory foam and high-density support core,...
The Dourxi Dual Sided Crib Mattress feels less like a typical crib mattress and more like a miniature version of a high-end adult memory foam bed. Its triple-layer construction, including gel-infused and open-cell memory foam, is designed for comfort and temperature regulation. We found the dual-sided design to be well-executed, with a distinctly firm side for infants and a noticeably plusher, more comfortable side for toddlers. One parent who upgraded from a cheap mattress noted the Dourxi was “firmer and plusher” and their son was sleeping much better. The removable cotton-blend cover is soft and washable, and we appreciated the included paper cutter for safely opening the vacuum-sealed packaging.
The primary issue with this mattress, similar to other compressed foam products, is the risk of improper expansion. While our unit expanded perfectly to its 6-inch height, many users have reported significant problems, with mattresses remaining lopsided, undersized, or never fully decompressing. An undersized mattress that leaves gaps in the crib is a serious safety hazard. To its credit, the company’s customer service appears responsive, with several users noting they received a replacement after reporting an issue. If you receive a properly expanded unit, this is a wonderfully comfortable and supportive mattress, but the “mattress lottery” aspect is a significant gamble.
Advantages
- Premium triple-layer memory foam construction
- Excellent dual-sided firmness for infants and toddlers
- Gel-infused foam helps with temperature regulation
- Soft, removable, and washable cover
Limitations
- Significant risk of improper or uneven expansion
- An undersized mattress can create dangerous gaps in the crib
- Not waterproof; requires a separate protector
#10 SEALY BABY Flex Cool 2-Stage Crib Mattress – Perfect for: Traditional Innerspring Support and Durability
- Natural & Cooling Breathable Crib Mattress - Cotton surface and airflow pocket offers breathability on baby's gentle skin. PVC-free...
- Sealy Crib Mattress 2 Stage Design - Grow with me baby crib mattress design offers a firmer infant side ideal for newborns and a cozier...
For parents who prefer the traditional, durable feel of an innerspring mattress, the SEALY BABY Flex Cool 2-Stage Crib Mattress is a leading choice. It features a core of 204 premium steel coils, providing robust, even support across the entire surface. We were impressed by the steel edge frame, which reinforces the sides and prevents sagging when a child stands or sits on the edge—a feature often found in adult mattresses. The dual-firmness design offers a very firm side for infants and a slightly softer side for toddlers, supported by the responsive coil system. Its GREENGUARD Gold certification ensures a healthy sleep environment.
However, our experience and user feedback revealed some significant quality control issues. Several users reported the mattress arriving dirty or stained, even when sealed in plastic. We also found some truth to complaints about the noise; the springs can creak and “boing” with movement, which could potentially disturb a light sleeper. The most serious concerns are around durability, with some reviews showing springs breaking through the mattress fabric after only a few months. While the Sealy brand name carries weight and the design concept is solid, the inconsistent manufacturing quality makes it a riskier purchase than some of its foam-based competitors.
What We Like
- Durable innerspring coil system provides firm, even support
- Reinforced steel edge frame prevents sagging
- GREENGUARD Gold certified for air quality
- Dual-sided design for infants and toddlers
What We Didn’t Like
- Numerous reports of poor quality control (stains, undone stitching)
- Springs can be noisy with movement
- Some users experienced springs breaking through the cover over time
The Ultimate Buyer’s Guide: How to Choose The Right Product for You
Key Factors to Consider
- Firmness and Support: This is non-negotiable for infants. A baby’s mattress must be very firm and flat to reduce the risk of SIDS. Many mattresses are “2-stage” or “dual-sided,” offering a firm side for infants and a slightly softer, more comfortable side for toddlers.
- Breathability: A key feature for peace of mind. Breathable mattresses are designed to allow air to flow freely, which can help regulate temperature and, most importantly, reduce the risk of suffocation and CO2 rebreathing if a baby rolls onto their stomach.
- Materials and Certifications: Look for certifications like GREENGUARD Gold (tests for low chemical emissions) and CertiPUR-US (ensures foam is made without harmful chemicals). Materials range from foam and innersprings to innovative woven polymers. Avoid mattresses with flame retardant chemicals.
- Fit and Size: A crib mattress must fit snugly inside a standard crib with no gaps larger than two fingers between the mattress and the crib frame. This prevents the baby from getting trapped.
- Waterproofing and Washability: Babies are messy. A waterproof cover is essential for protecting the mattress core from diaper leaks and spit-up, which can lead to mold and bacteria. A removable, machine-washable cover is a huge convenience for parents.
Understanding Breathability
What does “breathable” really mean in a crib mattress? It refers to the ability of the mattress to circulate air. This is achieved in several ways:
- Porous Core: The most advanced breathable mattresses, like the Newton, use a core made of a woven food-grade polymer that is almost entirely air. This allows a baby to breathe normally even if their face is pressed directly against the surface.
- Vented Foam: Many foam mattresses incorporate breathability through perforated cores or airflow channels cut into the foam, which helps air circulate and heat dissipate.
- Breathable Covers: Some mattresses feature covers with a 3D mesh design that creates a layer of air between the baby and the mattress surface, enhancing airflow.
While all these methods help, the level of breathability can vary greatly. A fully breathable core offers the highest level of safety against suffocation.
Common Mistakes to Avoid
- Choosing a Mattress That’s Too Soft: While it may feel cozy to you, a soft mattress is a serious safety hazard for an infant. Always prioritize firmness.
- Ignoring the Fit: Never use a mattress that leaves gaps in the crib. Measure your crib’s interior dimensions and ensure the mattress fits snugly.
- Forgetting About Cleaning: Overlooking a waterproof or washable cover will lead to a stained, unhygienic mattress. Prioritize ease of cleaning.
- Using Aftermarket Add-ons: Avoid using soft mattress toppers, thick pads, or anything not provided by the manufacturer in an infant’s crib, as these can compromise the safety and firmness of the sleep surface.
Frequently Asked Questions
Why is breathability crucial for a baby’s crib mattress?
Breathability is crucial primarily for safety. It allows air to circulate around the baby, which helps in two key ways: it reduces the risk of suffocation if the baby rolls face-down, and it helps prevent overheating, another SIDS risk factor. It also offers immense peace of mind for parents.
How does a breathable crib mattress help regulate temperature?
Traditional mattresses can trap heat, causing a baby to become sweaty and uncomfortable. A breathable mattress allows that heat to dissipate and fresh air to circulate, creating a more stable and comfortable sleep temperature for your little one.
What materials or designs make a crib mattress breathable?
Several designs promote breathability. The most effective is a woven polymer core (like Newton’s Wovenaire), which is mostly air. Other methods include perforated foam cores with air channels, innerspring designs that naturally have more air space, and 3D mesh covers that create an air layer on the surface.
Do breathable mattresses reduce the risk of rebreathing CO2?
Yes, this is a key benefit. When a baby sleeps face-down on a non-breathable surface, they can rebreathe their own exhaled carbon dioxide (CO2), which can be dangerous. A highly breathable mattress allows the CO2 to dissipate away from the baby’s face, ensuring they are breathing fresh air.
Are highly breathable crib mattresses difficult to clean?
On the contrary, many are the easiest to clean. Models with washable cores can be completely rinsed in a shower to remove any messes, dust mites, or allergens. Most breathable mattresses also come with removable, machine-washable covers, making routine cleaning simple.
What are the best brands known for breathable crib mattresses?
Newton Baby is the pioneer and leader in 100% breathable and washable mattresses. Other reputable brands like Graco, Milliard, and Sealy also offer models with breathable features, such as perforated foam cores or airflow pockets, providing good options at various price points.
Does a breathable mattress compromise firmness or support?
No, a well-designed breathable mattress should not compromise on firmness. Leading brands engineer their products to meet or exceed all safety standards for infant sleep, which includes providing a firm, flat, and supportive surface. They are designed to be both highly breathable and safely firm.
Conclusion: Our Final Recommendation
After rigorous testing and evaluation, we confidently stand by our top pick: the Graco Premium Crib & Toddler Mattress Waterproof Cover. It masterfully balances all the critical elements a parent looks for in a crib mattress. It provides the essential firm support for infant safety, backed by an impressive array of certifications like GREENGUARD Gold and CertiPUR-US that guarantee a non-toxic sleep environment. Its practicality is unmatched at this price, with a soft, quiet, and machine-washable waterproof cover that handles messes without disturbing sleep. While it may not have the 100% breathable core of a premium-priced option, it offers excellent breathability through its perforated foam and delivers overwhelming value. For a safe, durable, and affordable mattress that will serve your child well from infancy to their toddler years, the Graco Premium is the smartest choice you can make.
