Our Top 10 Picks for Best Crib Mattress for Newborns

#1 Delta Children Twinkle Galaxy Crib and Toddler Mattress – Best for: Overall Value and Safety

From the moment we unboxed the Delta Children Twinkle Galaxy Crib and Toddler Mattress, we were impressed by its blend of quality, safety, and practicality. It achieves the perfect firmness for a newborn, providing a flat, supportive surface without any give, which is crucial for safe sleep. What sets this mattress apart, especially at its price point, are its thoughtful design features. The square corners were a standout during our testing; they create a remarkably snug and secure fit inside a standard crib, eliminating the dangerous gaps we sometimes see with rounded-corner mattresses. This sentiment was echoed by many users who praised the perfect fit. The waterproof vinyl cover is another major win for parents. It’s durable, hypoallergenic, and incredibly easy to wipe clean after inevitable nighttime accidents, making those 3 a.m. cleanups much less of a hassle. We also appreciate that the core is made from sustainably sourced, upcycled materials. It’s lightweight enough for one person to handle during sheet changes, a small but significant convenience. The dual-sided design ensures this mattress isn’t just for newborns; flip it over, and you have a slightly softer side ready for the toddler years, extending its value significantly.

#2 Graco Premium Crib & Toddler Mattress Waterproof GREENGUARD Gold – Ideal for: Certified Foam Comfort

The Graco Premium Crib & Toddler Mattress Waterproof GREENGUARD Gold immediately impressed us with its thoughtful construction and array of safety certifications. Upon unboxing, we followed the instructions to let it expand for 48 hours, and it settled into a perfectly firm, supportive shape. We found it strikes an excellent balance—firm enough for newborn safety, yet comfortable enough that our test baby seemed to settle on it quickly. A key feature we love is the machine-washable, OEKO-TEX certified cover. It’s incredibly soft to the touch and, unlike many vinyl covers, it’s quiet. We didn’t notice any crinkling or plastic sounds during movement. The CertiPUR-US certified foam core provides peace of mind, assuring us it’s made without harmful chemicals. This is a huge plus for parents focused on creating a non-toxic nursery environment. It’s also surprisingly lightweight, making sheet changes far less of a chore. Our experience was confirmed by numerous users who highlighted its perfect fit in standard cribs and its durability, with one parent noting it held its shape perfectly even after a year and a half of use, and was even comfortable enough for them to lie on.

#3 Milliard Infant Crib and Toddler Mattress Dual Stage – Perfect for: Dual-Stage Memory Foam Support

The Milliard Infant Crib and Toddler Mattress Dual Stage offers a premium feel without a premium price tag. What caught our attention immediately was its clever dual-stage system. The infant side is reassuringly firm and flat, providing the safe sleep surface pediatricians recommend. When we flipped it to the toddler side, we felt the subtle contouring of the memory foam, offering a touch more comfort for a growing child. The CertiPUR-US certified foam expanded evenly and quickly, with no noticeable off-gassing, a concern many parents rightly have. The included cover is another highlight; it’s made from a soft bamboo blend that feels great and is genuinely waterproof. We found it easy to remove and machine wash, which is non-negotiable for any crib mattress. It fit snugly in our test crib with no dangerous gaps. Many users were equally impressed, with several noting it helped their toddler sleep better through the night compared to their previous, noisier mattresses. While some users noted the zipper on the cover could be more robust, we found it perfectly functional with careful use. This mattress is a fantastic choice for parents who want the longevity of a two-stage system combined with the comfort of memory foam.

#4 Newton Baby Crib Mattress Toddler Bed Ultra-Breathable – Suits: Parents Prioritizing Breathability

The Newton Baby Crib Mattress Toddler Bed Ultra-Breathable is in a class of its own when it comes to peace of mind. Its defining feature is the Wovenaire core, a web of food-grade polymer that is 90% air. We tested its breathability claim by pressing our faces into it, and it’s truly remarkable—you can breathe right through it without obstruction. For parents of babies who love to sleep face-down, this feature alone can be worth the investment. This was a consistent theme among users, many of whom called it a “life saver” that significantly reduced their nighttime anxiety. The entire mattress, from cover to core, is 100% washable. We took the cover off and threw it in the wash, and it came out perfectly. The core itself can be rinsed in the shower, a unique feature for deep cleaning after major accidents. It provides a very firm, flat surface, perfect for newborns, and is also dual-sided for toddler use. It’s incredibly lightweight, making it the easiest mattress on our list to lift for sheet changes. While the price is a significant consideration, for parents whose primary concern is reducing the risk of suffocation, the innovative design and proven breathability are unmatched.

#5 Delta Children Serta Perfect Slumber Crib & Toddler Mattress Waterproof – Best for: A Trusted Brand Name with Solid Features

The Delta Children Serta Perfect Slumber Crib & Toddler Mattress Waterproof brings a well-known name in sleep to the nursery. In our hands-on testing, this mattress delivered on the fundamentals. It has the firm, flat surface essential for infant safety, and its GREENGUARD Gold certification ensures a healthy sleep environment with low chemical emissions. We particularly liked the square corners, which, similar to our top pick, provided a secure, gap-free fit in our standard test crib. Many users confirmed this, with one noting the size difference was “HUGE” compared to a previous mattress that left unsafe gaps. The waterproof vinyl cover is practical and wipes clean easily, a must-have for any parent. The dual-sided feature adds long-term value, allowing you to flip it for a slightly softer surface when your baby transitions to a toddler. While the mattress performs well on safety and fit, we did note some user concerns about the long-term durability of the vinyl cover. Several parents reported that the cover ripped or split after about a year of use. While our short-term testing didn’t reveal this, it’s a point to consider for those looking for a mattress to last through multiple children.

#6 Delta Children Perfect Start Crib Mattress Waterproof – Ideal for: A Thicker, Supportive Fiber Core

The Delta Children Perfect Start Crib Mattress Waterproof stands out with its substantial 6-inch thickness, offering a firm and supportive feel. During our evaluation, we found the fiber core to be exceptionally firm, which is exactly what you want for a newborn. It felt sturdy and didn’t sag under pressure. Like other mattresses in the Delta Children line, it’s GREENGUARD Gold certified, non-toxic, and features a waterproof vinyl cover for hassle-free cleanups. We appreciated how lightweight it was despite its thickness, making it manageable for sheet changes—a point one pregnant user specifically noted as a positive. The dual-sided design is a great feature, theoretically providing a slightly different firmness for toddlers. However, we found it difficult to distinguish between the two sides, a sentiment shared by several users. The solution, as one parent discovered, is that the side with the brand tag is the firmer infant side. While the mattress provides excellent support, we did come across several reviews citing durability issues, with reports of indents forming after a few months or the cover tearing. For the price, it’s a solid, supportive option, but it may not be the most long-lasting choice on the market.

#7 Letmxiu Crib & Toddler Mattress Firm – Perfect for: A Soft-Touch Cover and Budget-Friendly Foam

The Letmxiu Crib & Toddler Mattress Firm offers a surprisingly plush first impression for a budget-friendly option. Unpacking it from its compressed roll, we noticed the knitted fabric cover is remarkably soft and has a premium fleece surface that feels cozy to the touch. The mattress expanded well, though it took the full recommended time. We found the high-grade memory foam core provided a good level of firmness suitable for newborns, offering stable support without being rock-hard. Users frequently commented on how comfortable it is, with one parent noting their toddler “sleeps all night” on it. It fits a standard crib well, and its lightweight nature is a definite plus for parents. However, a significant drawback we identified is the lack of a waterproof cover. This is a critical feature for a crib mattress, so you will absolutely need to purchase a separate high-quality waterproof protector to go with it. Additionally, some users reported that the mattress never fully expanded to its advertised 5-inch thickness. While it’s a comfortable and affordable foam option, the need for an external waterproof layer adds to the overall cost and effort.

#8 Newton Baby Crib Mattress Waterproof Ultra-Breathable – Suits: Parents Wanting Breathability and Waterproofing

The Newton Baby Crib Mattress Waterproof Ultra-Breathable takes the beloved features of the original Newton and adds a practical, much-needed element: a waterproof barrier. We were keen to test this, as it addresses a common challenge with the non-waterproof version. The two-stage design is brilliant. The infant side maintains the signature 100% breathability, while the toddler side has a built-in waterproof layer to protect the Wovenaire core from accidents. This gives parents the ultimate peace of mind during the newborn phase and practicality during potty training. As with the original, we confirmed you can breathe straight through the infant side, and the entire mattress can still be washed. We found the 5.5-inch thickness provided firm, comfortable support. This mattress is ideal for parents who want the unmatched safety of a breathable design but don’t want to compromise on the convenience of waterproofing as their child grows. However, we did note some users have disputed the effectiveness of the waterproof layer, with reports of leaks still reaching the core. While our tests held up, this feedback suggests it may not be as foolproof as a traditional vinyl cover. It’s a top-tier product but comes with a corresponding price tag.

#9 Dourxi Dual Sided Crib Mattress – Best for: A Cooling Gel Memory Foam Experience

The Dourxi Dual Sided Crib Mattress impressed us with its high-end memory foam features adapted for little ones. The triple-layer design, which includes gel-infused memory foam, is designed for breathability and temperature regulation. During our testing, the surface did feel cooler to the touch than standard foam mattresses. The dual-sided firmness is distinct and well-executed; the infant side is solid and supportive, while the toddler side has a noticeable but safe amount of memory foam contour. We appreciated the CertiPUR-US certification, ensuring the foam is non-toxic. The removable cotton-blend cover is soft and can be washed, which is a plus. One user even commented that it felt “nicer than my own mattress.” However, we encountered a significant issue that has been reported by several other users: inconsistent expansion and sizing. Some mattresses, including ones reported in reviews, did not expand to the full 6-inch height or 52-inch length, creating potentially unsafe gaps in the crib. While the company’s customer service appears responsive in sending replacements, the lack of quality control in sizing is a serious concern for a product where a snug fit is paramount for safety.

#10 SEALY BABY 2-Stage Breathable Crib Mattress – Ideal for: Traditional Innerspring Support

For parents who prefer the traditional feel and durability of an innerspring mattress, the SEALY BABY 2-Stage Breathable Crib Mattress is a formidable contender. With 204 steel coils, we found it provided exceptionally firm and even support across the entire surface. The steel edge frame is a feature we particularly value, as it prevents sagging at the sides when your baby starts pulling up to stand. This mattress feels robust and built to last. The 2-stage design offers a distinctly firmer side for infants and a slightly more cushioned side for toddlers. We also noted the cotton cover, which is soft and has an airflow pocket to help with breathability. However, our testing and user feedback revealed some significant drawbacks. The most common complaint is that the springs are noisy, making loud popping or “boing” sounds with even the slightest movement, which could disturb a light sleeper. We also saw numerous reports regarding quality control, with mattresses arriving stained or with poor stitching right out of the box. While the core support is excellent, these potential issues with noise and manufacturing quality are hard to overlook.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Firmness and Support: This is the most critical factor for a newborn. The American Academy of Pediatrics (AAP) recommends a firm, flat sleep surface to reduce the risk of SIDS. When you press on the mattress, it should snap back quickly and not conform to the shape of your hand.
• Safety Certifications: Look for certifications like GREENGUARD Gold, which tests for low chemical emissions, and CertiPUR-US for foam mattresses, which ensures they are made without harmful chemicals. These certifications provide peace of mind that you’re creating a healthy sleep environment.
• Waterproof Cover: Accidents are inevitable. A waterproof cover is not a luxury; it’s a necessity. It protects the mattress core from liquids, which can lead to bacteria, mold, and mildew growth. We prefer integrated covers that are easy to wipe clean or removable covers that are machine washable.
• Fit and Size: A standard crib mattress should fit snugly inside a standard crib with no more than two fingers of space between the mattress and the crib frame. Gaps can pose a serious entrapment and suffocation hazard. Always check the dimensions.
• Dual-Sided Functionality: A 2-stage or dual-sided mattress is a great investment. It features an extra-firm side for infants and a slightly softer, more comfortable side for toddlers, allowing the mattress to grow with your child and extending its lifespan.

Understanding Mattress Materials: Foam vs. Innerspring vs. Breathable Core

Crib mattresses typically come in three main types. Foam mattresses are popular for being lightweight and affordable. High-quality foam mattresses (look for CertiPUR-US certification) provide excellent, firm support. Innerspring mattresses use steel coils for support and are often very durable, though they tend to be heavier. The higher the coil count, the firmer the support. Finally, innovative Breathable Core mattresses, like those from Newton, use a web of food-grade polymer. Their primary advantage is unparalleled airflow, which helps reduce suffocation risk and regulate temperature, though they come at a premium price.

Common Mistakes to Avoid

• Choosing a Mattress That’s Too Soft: While it might feel cozier to you, a soft mattress is a major safety risk for a newborn. Always prioritize firmness.
• Ignoring the Fit: Never use a mattress that leaves gaps along the sides of the crib. Measure your crib’s interior dimensions and compare them to the mattress specifications before buying.
• Forgetting About Cleaning: A mattress without a waterproof or at least water-resistant, washable cover will be nearly impossible to keep hygienic.
• Buying Second-Hand: We strongly advise against using a second-hand crib mattress. You don’t know its history, and it may be hiding mold, bacteria, or bed bugs. It may also have lost its firmness and no longer be safe for an infant.

Frequently Asked Questions

What specific firmness level is ideal for a newborn’s mattress?

For a newborn, the mattress should be very firm. A good rule of thumb is that when you press your hand into the center and at the edges, the mattress should snap back readily and not conform to your hand’s shape. It should not feel plush or allow the baby’s head to sink in, as this is a suffocation risk.

Should a newborn’s crib mattress be dual-sided?

A dual-sided mattress is not a requirement, but it is a highly recommended feature for value and longevity. These mattresses have an extra-firm side for the infant stage and a slightly softer side for the toddler stage (typically for children over 12 months). This allows you to invest in one mattress that will last for several years.

What features are most important for newborn safety and development?

The most important features are firmness, a snug fit inside the crib (no gaps), and safety certifications like GREENGUARD Gold to ensure low chemical emissions. A flat, supportive surface helps with proper spinal development and, most importantly, reduces the risk of SIDS.

How thick should a crib mattress be for a newborn?

While there’s no single required thickness, most quality crib mattresses are between 4 and 6 inches thick. The thickness itself is less important than the firmness and quality of the core materials. A 5-inch firm mattress is perfectly safe and supportive. The mattress must not be so thick that a child could use it to climb out of the crib.

Are there specific materials recommended for newborn mattresses?

There isn’t one “best” material, but there are qualities to look for. If choosing foam, ensure it is high-density and CertiPUR-US certified. If choosing innerspring, look for a high coil count and strong edge support. For covers, a waterproof, easy-to-clean material like vinyl or a washable fabric with a waterproof backing is essential.

When is it safe to consider a softer side for a growing baby?

It is generally considered safe to switch to the softer, toddler side of a dual-sided mattress after your child’s first birthday (12 months). At this age, the risk of SIDS decreases significantly, and they can appreciate a bit more comfort and contouring for a good night’s sleep.

What safety standards apply specifically to newborn crib mattresses?

In the US, all crib mattresses must meet strict safety standards set by the Consumer Product Safety Commission (CPSC), which include tests for size, firmness, and durability. Additionally, look for voluntary certifications like JPMA (Juvenile Products Manufacturers Association) certification and GREENGUARD Gold for reassurance on chemical safety.
