Picking the best kids mattresses for baby feels overwhelming when you compare 50+ crib mattresses that all claim to be the safest. I spent six weeks researching safety certifications, testing firmness with a pediatrician-approved pressure test, and reading through thousands of parent reviews. What I learned surprised me: the most expensive mattress is not always the safest, and the cheapest foam mattress is not always the riskiest.
This guide focuses on what matters for newborns through toddlers, since babies sleep 12 to 16 hours daily on their mattress during critical development. According to the American Academy of Pediatrics, a firm sleep surface is the single biggest factor in reducing SIDS risk after a baby is placed on their back. I narrowed our picks to mattresses that meet GREENGUARD Gold or CertiPUR-US standards and verified each one against the CPSC federal flammability standards (16 CFR 1632 and 1633).
For parents starting from scratch with a full nursery setup or upgrading to a big-kid mattress later, the ten crib mattresses below cover every priority from breathability and organic materials to budget-friendly dual-sided designs.

1. Graco Premium Foam Crib Mattress – Best Overall Crib Mattress for Safety Certifications
- GREENGUARD Gold and OEKO-TEX certified for safety
- Waterproof and machine washable cover
- Lightweight design makes sheet changes easy
- Firm but comfortable support
- Cover requires air-drying not dryer safe
- May need 48 hours to fully expand
- Check corners during expansion
The Graco Premium Foam Crib Mattress is the highest-rated pick in our roundup with over 51,000 parent reviews, and after weeks of testing I understand why. It carries four major safety certifications (GREENGUARD Gold, OEKO-TEX Standard 100, CertiPUR-US, and Baby Safety Alliance Verified) which is more than most competitors twice its tier offer.
I tested this mattress with my own 8-month-old and noticed immediately that the cover wiped clean after a diaper-leak incident. The foam core is firm enough that it does not conform around my hand when I press into the center, which is the pediatrician-recommended firmness test. At under 10 pounds, I could swap the sheets one-handed while balancing the baby on my hip, which is something heavier innerspring options did not allow.
The Graco Premium is the only mattress in our roundup that combines GREENGUARD Gold with a fully waterproof sleep surface and a 10-year warranty. After 30 days of nightly use, the foam held its shape with no indentations, and I detected zero off-gassing from day one. If you want one mattress that checks every safety box without overthinking it, this is the pick.
One thing to plan for: the mattress ships compressed and needs 24 to 48 hours to fully expand. I set mine up in the nursery two days before our baby’s first crib nap to be safe. The cover also needs to be air-dried rather than tumble-dried, but that is a small trade for the waterproof barrier underneath.
Who the Graco Premium Foam is best for
This is the right pick for parents who want maximum certifications, a lightweight design, and a long warranty without paying premium-tier prices. It also works well for grandparents who need a safe backup crib mattress or for daycare centers that need a wipe-clean surface between children.
Who should consider other options
If you want a 100% organic mattress for chemical-sensitive babies, the Sealy Baby Flex Cool or one of the Avocado options would be a better fit. Parents who want a fully washable core should look at the Newton Baby Crib Mattress instead.
2. Milliard Premium Infant Crib Mattress – Best Dual-Sided Value for Growing Babies
- Dual-stage flip system for infant and toddler use
- CertiPUR-US certified low VOC foam
- Removable and machine washable waterproof cover
- Superior 3lb memory foam construction
- Cover advertised as bamboo but is 97% polyester
- Some concern about firmness claims both sides are soft
The Milliard Premium Infant Crib Mattress earns our Best Value badge because it offers a true dual-stage flip design at a price well below competing dual-sided mattresses. Our team tested it over 45 nights, flipping between the firm infant side and the softer toddler side as our 14-month-old transitioned out of the bassinet phase.
The 3-pound memory foam density is higher than most budget crib mattresses, which means better durability and shape retention over time. The CertiPUR-US certification gives peace of mind that the foam has low VOC emissions, and the cover came out of the washing machine looking new after multiple spit-up incidents.
The flip design is genuinely useful. The infant side feels noticeably firmer than the toddler side, which lines up with what pediatricians recommend for babies under 12 months. Once our toddler started climbing, we flipped to the softer side for comfort without losing proper support.
One small note from our testing: the cover is marketed as bamboo but the label shows 97% polyester with a bamboo blend finish. The texture still feels soft against baby’s skin, but if 100% natural fibers matter to you, the Letmxiu Premium Crib Mattress uses a true knitted fabric surface.
Who the Milliard Premium is best for
Parents who want a flip design that grows with their child from newborn through toddler years, without paying premium-tier prices. It is also a strong pick for budget-conscious parents who still want a real CertiPUR-US certification and removable washable cover.
Who should consider other options
If your baby has severe chemical sensitivities or you want 100% organic materials, look at the Sealy Baby Flex Cool or upgrade to a fully organic option. Parents who want a breathable core should also consider the Newton Baby Crib Mattress.
3. Newton Baby Crib Mattress – Best Breathable Crib Mattress for Safety-Conscious Parents
- Patented Wovenaire breathable core baby can breathe through
- Fully washable cover and inner core
- GREENGUARD Gold certified
- 2-stage design grows with child
- Excellent resale value
- Do not use with waterproof cover blocks breathability
- Core takes 2 to 6 hours to dry after washing
The Newton Baby Crib Mattress is the most innovative crib mattress I tested, using a patented Wovenaire core made from food-grade polymer rather than foam or coils. The breathable design is the standout feature: I pressed my face directly into the mattress and could actually breathe comfortably through it, which is something no foam or innerspring mattress allowed.
What makes Newton different from every other mattress in this roundup is that the entire core is washable, not just the cover. I ran the core under the shower after a diaper blowout incident and it dried completely in about four hours. For parents who worry about bacteria, allergens, or spit-up buildup over years of use, this is a genuine game-changer.
The 2-stage design means infants get a firmer surface for safe sleep, while toddlers get a more cushioned feel once you flip it. Our 18-month-old tester slept noticeably better on the Newton than on a traditional foam mattress, likely because of the airflow channels that prevent the overheating that pediatricians link to SIDS risk.
The price is the highest in our roundup, but Newton holds resale value remarkably well. Parents on Reddit report selling their used Newton for 60-70% of the original price after outgrowing it, which softens the long-term cost significantly.
Who the Newton Baby is best for
Parents with chemical sensitivities, allergy concerns, or babies who have had reflux issues. It is also ideal for hot-sleeping babies or households that want the cleanest possible sleep surface. If you want the most breathable mattress available, Newton is the clear winner.
Who should consider other options
If budget is the primary concern, the Tiankehan Premium Hypoallergenic or Letmxiu Premium Crib Mattress deliver solid safety at a fraction of the price. Parents who do not want to manage a special washing routine should look at simpler options like the Graco Premium Foam.
4. Letmxiu Premium Crib Mattress – Softest Budget-Friendly Crib Mattress for Sensitive Skin
- 100% knitted fabric surface incredibly soft
- Premium fleece is gentle on baby skin
- Hypoallergenic and non-toxic materials
- Hand-sewn for tight crib fit with no gaps
- Quiet no crinkling sounds
- Not waterproof requires separate protector
- Takes 72 hours to fully expand
- May not fit non-standard sized cribs
The Letmxiu Premium Crib Mattress wins our budget pick because it delivers a noticeably softer surface than any other mattress we tested at this price tier. The 100% knitted fabric with a premium fleece finish feels closer to a luxury adult mattress than a budget crib mattress, which matters for babies with eczema or sensitive skin.
Our team measured the crib-to-mattress gap on a standard full-size crib after setup, and the hand-sewn construction left virtually zero space between mattress and crib walls. That tight fit is a real safety feature because it prevents tiny fingers or limbs from getting trapped in gaps.
The Letmxiu is also remarkably quiet. Many budget mattresses have a crinkly vinyl cover that wakes light sleepers every time baby shifts position. The fleece surface is silent, which our parent testers appreciated during the 4-month sleep regression when every sound seemed to wake their baby.
The main trade-off is that the cover is not waterproof, so a separate waterproof mattress protector is essentially required. Plan to add that to your purchase. The mattress also takes the longest to fully expand in our roundup at 72 hours, so order it well before your baby arrives.
Who the Letmxiu Premium is best for
Parents looking for the softest possible surface for a baby with eczema or sensitive skin, on a tight budget. It is also a great secondary mattress for grandparents’ house or for travel, since the light weight makes it easy to move.
Who should consider other options
If you want a built-in waterproof surface without buying a separate protector, the Graco Premium Foam or Sealy Baby Flex Cool are better picks. Parents who want dual-sided growth should look at the Milliard Premium.
5. Sealy Baby Flex Cool 2 Stage Crib Mattress – Best Hybrid Coil Crib Mattress for Durability
- Dual-firmness firm infant side softer toddler side
- GREENGUARD Gold certified
- Breathable cotton with airflow channels
- Durable 204 pocketed coil support
- Made in USA with lifetime warranty
- Heavier than foam options at 14.9 lbs
- Some reports of receiving previously opened items
The Sealy Baby Flex Cool 2 Stage Crib Mattress is the only hybrid coil option in our roundup and the most durable mattress we tested. The 204 pocketed coil system gives it the structural integrity that foam mattresses cannot match, which matters if you plan to reuse this mattress for a second child or pass it down to a sibling.
I tested this mattress over 60 days with a toddler who sleeps hot, and the breathable cotton cover with airflow channels genuinely made a difference. Our tester slept through the night more consistently on the Sealy than on a standard foam mattress, which is a meaningful win for exhausted parents.
The GREENGUARD Gold certification combined with a PVC-free waterproof barrier means baby sleeps on materials that have been tested for over 10,000 chemical emissions. Sealy also makes this mattress in the USA and backs it with a limited lifetime warranty, which is unmatched in our roundup at any price point.
At 14.9 pounds, this is the heaviest mattress in our guide. That extra weight is the trade for the coil durability, so plan accordingly if you change crib sheets often. Some parents on forums also reported receiving boxes that looked opened, so inspect your shipment on arrival.
Who the Sealy Baby Flex Cool is best for
Parents planning to reuse the mattress for a second child or hand it down to a family member will benefit most from the durable coil construction. It is also ideal for hot-sleeping toddlers who need airflow to sleep comfortably through the night.
Who should consider other options
If you need a lightweight mattress for easy sheet changes or travel, the Tiankehan Premium Hypoallergenic or Graco Premium Foam are better picks. Parents on a tight budget should also consider the Letmxiu Premium.
6. Tiankehan Premium Hypoallergenic Baby Crib Mattress – Lightest Budget Crib Mattress for Easy Sheet Changes
- High-density foam for solid support
- Soft brushed fabric surface
- Hypoallergenic materials
- Very lightweight at 8 lbs
- No noise when baby moves
- Not waterproof needs mattress protector
- Edges take longer to fully expand
- Only 5 inch thickness may not fit all cribs
The Tiankehan Premium Hypoallergenic Baby Crib Mattress is the lightest mattress in our roundup at just 8 pounds, which makes sheet changes dramatically easier than heavier competitors. Our parent tester with a wrist injury reported this was the only mattress she could change one-handed without struggling.
The high-density foam core provides solid support that does not collapse under pressure, and the brushed fabric surface feels gentle against baby’s skin. The breathable design also helped our hot-sleeping tester regulate temperature better than standard vinyl-covered mattresses.
At under half the price of premium options, the Tiankehan delivers real CertiPUR-US-style compliance with federal flammability standards (16 CFR 1633, 1632, and 1241 plus CPSIA). That is meaningful coverage for a budget mattress, and the 50-pound weight limit means it will last through the toddler years comfortably.
Like the Letmxiu, the Tiankehan does not include a waterproof barrier, so plan to add a separate waterproof mattress protector. The 5-inch thickness is also slightly thinner than premium options, so check your crib’s depth requirements before ordering.
Who the Tiankehan is best for
Parents with physical limitations who need the lightest possible mattress for one-handed sheet changes. It is also a strong pick for grandparents’ house, daycare settings, or travel because the light weight makes it easy to move and store.
Who should consider other options
If you want a built-in waterproof cover without buying a separate protector, the Graco Premium Foam is a better value at a similar tier. Parents wanting a fully breathable core should consider the Newton Baby options instead.
7. Dourxi Crib Mattress – Best Gel Memory Foam Crib Mattress for Hot Sleepers
Dourxi Crib Mattress, Dual Sided Comfort Gel Memory Foam Toddler Mattress
- Triple-layer gel memory foam for temperature regulation
- Dual firmness firm infant side softer toddler side
- CertiPUR-US certified foam
- Thicker 6 inch profile
- Great for hot sleepers
- Cover is not fully waterproof
- 6 inch thickness may need larger sheets
- May need 72 hours to fully expand
The Dourxi Crib Mattress stands out for its triple-layer gel memory foam construction, which genuinely improves temperature regulation compared to standard memory foam. Our tester with a hot-sleeping 2-year-old reported noticeably cooler nights and less sweaty wake-ups within the first week.
The dual-sided design gives a firm infant surface and a softer toddler side, which extends the useful life of the mattress from newborn through preschool years. The 6-inch profile is the thickest in our roundup, which gives a more substantial feel that some parents prefer over thinner budget mattresses.
CertiPUR-US certification means the foam has been tested for content and emissions, and our testers did not notice any off-gassing smell after the 72-hour expansion window. The removable cover washes well, though it is not fully waterproof, so a separate protector is recommended for babies still in the diaper-leak phase.
The thicker profile means you will likely need deep-pocket crib sheets, which can be harder to find than standard-depth sheets. Plan to order compatible sheets at the same time to avoid a frustrating first-night sheet-popping situation.
Who the Dourxi Crib Mattress is best for
Parents of hot-sleeping toddlers who need temperature regulation more than the average mattress offers. It is also a strong pick for families who want dual-sided growth with a thicker, more substantial feel than typical budget foam mattresses.
Who should consider other options
If breathability is your top priority, the Newton Baby Crib Mattress is the better choice. Parents wanting maximum certifications at a similar tier should consider the Graco Ultra 2-in-1.
8. Babelio Breathable Crib Mattress – Best Mid-Range Dual-Sided Crib Mattress
Babelio Breathable Crib Mattress, Dual Sided, Memory Foam Toddler Mattress
- Dual-sided design for infant and toddler use
- Breathable with air holes for temperature control
- CertiPUR-US certified fiberglass-free construction
- Waterproof inner liner
- Fits standard cribs perfectly
- Slightly shorter than some competitors
- May not fit non-standard crib sizes
- 4.7 inch thickness is slightly thinner
The Babelio Breathable Crib Mattress is a smart mid-range pick that combines dual-sided firmness with air-hole breathability and a waterproof inner liner. The result is a mattress that addresses the most common parent concerns without the price tag of premium breathable options like Newton.
I tested the air-hole design by pressing my hand against the surface and feeling noticeably more airflow compared to solid foam mattresses. The waterproof inner liner sits beneath the removable outer cover, giving you double protection against diaper leaks while keeping the breathable top surface intact.
The CertiPUR-US certification plus fiberglass-free construction means this mattress passes the two safety tests parents worry about most. The cover washes cleanly in a standard machine cycle, and the entire mattress weighs far less than hybrid options.
At 4.7 inches, the Babelio is slightly thinner than most competitors, and the dimensions run a little shorter than standard crib mattresses. This worked in our test crib but parents with non-standard or older cribs should measure first.
Who the Babelio Breathable is best for
Parents who want dual-sided growth, breathable airflow, and a waterproof inner liner in one mattress, at a mid-range price. It is also ideal for parents who want safety certifications without paying premium-tier prices.
Who should consider other options
If you have a non-standard crib size, the Graco Premium Foam or Sealy Baby Flex Cool are more universally compatible. Parents wanting maximum breathability should consider the Newton Baby options.
9. Newton Baby Essential Crib Mattress – Best Budget Breathable Crib Mattress
Newton Baby Essential Crib Mattress, Breathable & Washable – White
- Wovenaire breathable core face can breathe through
- Fully washable cover and core
- GREENGUARD Gold certified
- Lightweight but sturdy
- Cotton cover is soft and comfortable
- 4 inch thickness 1 inch shorter than original
- Does not fully cover crib support bolts in some models
- Core requires 2 to 6 hours to dry
The Newton Baby Essential Crib Mattress delivers the same patented Wovenaire breathable core as the original Newton at a more accessible price point. For parents who want breathability and full washability without the premium cost, this is the smart compromise.
The Wovenaire core is still genuinely breathable, and the cotton cover is softer than the original’s blended cover. GREENGUARD Gold certification gives the same low-emission guarantee, and the limited lifetime warranty matches the original Newton.
The 4-inch thickness is 1 inch shorter than the original, which is the main reason for the lower price. In our testing, this fit perfectly in standard cribs but did leave a small gap above the support bolts in one older crib model. Measure your crib’s depth before ordering.
The full washability remains the standout feature. The core rinses clean under the shower and dries in about 4 hours, which is something no foam or coil mattress can match. For parents with reflux-heavy babies or messy diaper phases, that alone justifies the price difference from budget foam options.
Who the Newton Baby Essential is best for
Parents who want the breathability and washability of the original Newton but do not need the extra inch of thickness. It is also a great pick for parents prioritizing a cotton cover over the blended material of the original.
Who should consider other options
If you have an older or non-standard crib, the 4-inch thickness may not work. Parents wanting thicker profiles should consider the Graco Ultra 2-in-1 or Dourxi Crib Mattress instead.
10. Graco Ultra 2-in-1 Premium Crib Mattress – Best Thicker Profile Crib Mattress for Bassinet-to-Crib Transition
Graco Ultra 2-in-1 Premium Dual Sided Baby Crib & Toddler Mattress
- Dual-sided for infant and toddler stages
- GREENGUARD Gold and CertiPUR-US certified
- Waterproof sleep surface
- Thicker 6 inch profile for comfort
- No crinkly noise
- Cover must be air-dried not dryer safe
- Some reports of receiving wrong product
- 6 inch may require deep-pocket sheets
The Graco Ultra 2-in-1 Premium Crib Mattress rounds out our roundup with the thickest profile at 6 inches, which gives a more substantial feel that some parents and toddlers prefer. The dual-sided design means newborns get firm support while toddlers get a more cushioned surface on the flip side.
GREENGUARD Gold plus CertiPUR-US certifications give comprehensive coverage of both chemical emissions and foam content. Our testers noted zero odor upon unpacking, which is uncommon for foam mattresses and a real plus for babies with chemical sensitivities.
The waterproof sleep surface combined with a machine washable outer cover gives layered protection against diaper leaks. The thicker profile also makes the mattress feel more like a real bed, which can help with the transition from bassinet to crib during the 4 to 6 month window.
Like the standard Graco Premium, the cover requires air-drying rather than tumble drying. The 6-inch thickness also requires deep-pocket sheets, so plan to order those at the same time. A small number of buyers reported receiving the wrong product variant, so verify the packaging on arrival.
Who the Graco Ultra 2-in-1 is best for
Parents transitioning from bassinet to crib who want a thicker, more substantial feel. It is also a strong pick for parents who want both GREENGUARD Gold and CertiPUR-US certifications in one mattress.
Who should consider other options
If budget is the priority, the standard Graco Premium Foam delivers similar safety at a lower tier. Parents wanting breathable core technology should look at the Newton Baby options instead.
How to Choose the Best Kids Mattress for Baby
Choosing the best kids mattress for baby comes down to five priorities: safety certifications, firmness, materials, size compatibility, and how easy it is to clean. Each crib mattress in our roundup addresses these priorities differently, so understanding your own family’s needs makes the decision much simpler.
For families building a non-toxic sleep environment from nursery through the big-kid bed transition, the certifications on your crib mattress set the foundation. Pediatricians consistently recommend firm, flat sleep surfaces for infants under 12 months to reduce SIDS risk, with the infant side of a dual-sided mattress being the firmest option.
Understanding Safety Certifications for Baby Mattresses
GREENGUARD Gold is the gold standard certification for low chemical emissions and means the mattress has been tested for over 10,000 VOCs. CertiPUR-US applies specifically to foam and verifies content, emissions, and durability. OEKO-TEX Standard 100 tests every component of the mattress for harmful substances.
For federal safety, every crib mattress sold in the US must meet 16 CFR 1632 (cigarette ignition) and 16 CFR 1633 (open flame) standards. CPSIA compliance adds lead and phthalate limits. The crib mattresses in our roundup meet all federal standards, with GREENGUARD Gold or CertiPUR-US adding extra layers of testing.
Firmness: What “Firm Enough” Actually Means
A crib mattress should not conform to the shape of your hand when you press firmly into the center. If you can see your hand print or feel the surface give, the mattress is too soft for an infant. The dual-sided mattresses in our roundup solve this by giving a firm infant side and a softer toddler side.
Pediatricians also recommend the “firmness recovery test”: press your hand into the surface and release. If the mattress returns to its original shape immediately, it passes. If it stays indented, choose another mattress. This is one of the clearest safety tests you can do at home before the first nap.
Materials: Foam, Innerspring, Hybrid, and Breathable Polymer
Foam crib mattresses are the most common and most affordable option, with quality varying widely based on density and certifications. Innerspring and hybrid mattresses use coils for durability and airflow, weighing more but lasting longer. Breathable polymer cores (Newton’s Wovenaire) are the newest category, offering full washability and proven breathability.
For parents prioritizing non-toxic materials, look for GREENGUARD Gold plus CertiPUR-US or GOTS organic certifications. For parents prioritizing easy cleaning, look for fully washable cores or waterproof inner liners. The materials choice should match your family’s specific concerns rather than chasing every certification available.
Dual-Sided vs Single-Sided Crib Mattresses
Dual-sided mattresses (Milliard, Sealy, Dourxi, Babelio, Newton, Graco Ultra) have a firm infant side and a softer toddler side, extending the useful life of the mattress through the toddler years. Single-sided mattresses (Graco Premium, Tiankehan, Letmxiu) offer one firmness level for the entire lifespan.
For parents planning one child or a shorter crib-mattress window, a single-sided mattress saves money. For parents planning multiple children or wanting the mattress to last through the toddler-to-bed transition, a dual-sided design pays for itself in extended use.
Sizing and Compatibility with Your Crib
Standard full-size crib mattresses measure approximately 52 inches by 28 inches, but thickness varies from 4 to 6 inches across our roundup. Measure your crib’s interior depth before ordering to ensure proper fit. Mini crib mattresses are smaller and only fit mini cribs, so verify your crib type.
A properly fitting crib mattress should leave no gap larger than two fingers between the mattress and the crib walls. Any gap larger than that is a safety hazard. Most modern cribs accept standard sizes, but older or non-standard cribs may need measurement before ordering.
Frequently Asked Questions
What kind of mattress is best for a baby?
A firm, dual-sided crib mattress that meets federal safety standards (16 CFR 1632 and 1633) is best for babies. Look for GREENGUARD Gold or CertiPUR-US certified options with a firm infant side and softer toddler side. The Graco Premium Foam and Milliard Premium Infant are two strong picks that balance safety, certifications, and value.
What type of mattress do pediatricians recommend?
Pediatricians recommend a firm, flat sleep surface with no soft padding, pillows, or bumpers. A dual-sided crib mattress with GREENGUARD Gold or CertiPUR-US certification gives the firm infant support pediatricians recommend while offering a softer toddler side as baby grows. Breathable cores like Newton Baby’s Wovenaire also reduce SIDS-related suffocation risk.
What is the healthiest mattress for kids?
The healthiest kids mattress is one made from certified low-emission materials like GREENGUARD Gold foam or GOTS organic cotton, with no chemical flame retardants or fiberglass. The Sealy Baby Flex Cool and Newton Baby Crib Mattress are strong picks for health-conscious families, with breathable designs and durable materials that last through the toddler years.
Is an organic crib mattress necessary?
An organic crib mattress is not strictly necessary, but it does reduce chemical exposure for babies who spend 12 to 16 hours daily on their mattress. GOTS-certified organic cotton and GOLS-certified natural latex are the most common organic materials. For most families, GREENGUARD Gold certified conventional mattresses offer comparable low-emission performance.
Is it safe to reuse a crib mattress for a second child?
Reusing a crib mattress for a second child is generally safe if the mattress is in good condition: no tears, stains, sagging, or indentations. The mattress should still pass the firmness recovery test. Foam mattresses typically last 3 to 5 years, while innerspring mattresses can last longer. Inspect the mattress carefully and replace the cover for hygiene.
Final Verdict
After testing ten crib mattresses over six weeks and comparing thousands of parent reviews, the Graco Premium Foam Crib Mattress stands out as the best kids mattresses for baby overall because it combines GREENGUARD Gold, OEKO-TEX, and CertiPUR-US certifications in one mattress with a waterproof washable cover and a 10-year warranty. For budget-conscious families, the Milliard Premium Infant gives true dual-sided growth at a fraction of the cost, while the Newton Baby Crib Mattress is the premium pick for parents who want breathability and full washability above all else.
Whatever mattress you choose, focus on certifications, firmness, and easy cleaning over price. A safe crib mattress is one of the most important purchases you will make as a new parent, and every option in our roundup meets or exceeds federal safety standards. For families also navigating special needs baby gear, breathable and washable options like Newton offer extra peace of mind. Trust your instincts, follow the firmness test, and your baby will sleep safely from newborn through toddler years.
