Choosing the safest crib mattress is about more than airflow claims or materials. Look for a firm, flat surface that fits your crib snugly, then follow safe-sleep practices every time your baby sleeps.

None of these features replaces a fitted sheet, an empty crib, or placing your baby on their back to sleep.

Our Picks: Best Safest Baby Crib Mattress reviews
Newton Baby Crib Mattress: Best for Washing the Entire Mattress
This two-stage mattress has a Wovenaire core designed to let air pass through it. Its main practical distinction is that both the removable cover and inner core can be cleaned: the cover goes in the washing machine, while the core can be rinsed in a shower or bath. That approach may appeal to families who want to clean more than just the surface after a spill.
The mattress measures 52 by 28 by 5.5 inches, and the core is made in the USA. Newton also lists GREENGUARD Gold certification for low emissions. The two-stage design is intended for use from infancy through the toddler years, so you can keep the same mattress as your child grows.
Airflow is a design feature, not a substitute for safe-sleep practices or a guarantee against suffocation. This model also does not list a waterproof layer, unlike the waterproof Newton option below. Check your crib’s required mattress dimensions and fit before buying.
Pros:
- Both the cover and core are washable.
- Wovenaire core is designed for airflow.
- Two-stage design for infant and toddler use.
- GREENGUARD Gold certified for low emissions.
Cons:
- No waterproof layer is listed for this model.
- Its 5.5-inch thickness may not suit every crib’s mattress requirements.
Verdict: Choose this Newton model if whole-mattress cleanability and a washable breathable core matter more to you than built-in waterproof protection.
Newton Baby Waterproof: Best for a Waterproof Toddler Side
This Newton two-stage mattress keeps the washable Wovenaire core and removable cover found in the brand’s other models, with an added waterproof layer on the toddler side. That feature is intended to protect the mattress from moisture and accidents as your child moves into the toddler years.
It measures 52 by 28 by 5.5 inches. The cover is machine-washable, and the core can be rinsed clean. The product is also listed as GREENGUARD Gold certified for low emissions. Before ordering, confirm that the listed size works with your crib and check the manufacturer’s instructions for which side to use at each stage.
The waterproof layer is described as being on the toddler side, so it should not be assumed to protect both sides equally. As with other breathable mattresses, airflow claims do not replace a firm, flat sleep surface and other safe-sleep steps.
Pros:
- Waterproof layer on the toddler side helps guard against moisture.
- Washable cover and rinse-clean core.
- Two-stage design for infant and toddler use.
- GREENGUARD Gold certified for low emissions.
Cons:
- The waterproof layer is specified for the toddler side, not both sides.
- The 5.5-inch profile should be checked against your crib’s fit requirements.
Verdict: This is a practical pick if you want Newton’s washable core with added waterproof protection for the toddler stage.
Newton Baby Essential: Best for a Thinner Breathable Design
The Essential model uses Newton’s Wovenaire core and washable-cover design in a 4-inch-thick mattress. The core can be rinsed clean, while the cover is machine-washable. It is a two-stage model designed for infant and toddler use, and the product information lists GREENGUARD Gold certification for low emissions.
At 52 by 28 by 4 inches, it has a lower profile than the other two Newton options in this guide. That may be useful if you are comparing mattress thicknesses, but dimensions and fit still need to match your crib’s instructions. The supplied product details do not list a waterproof layer, so plan on a separate cleanup approach for spills.
Newton describes the core as breathable, but that feature should not be treated as protection from unsafe sleep conditions. Keep the sleep space clear and follow safe-sleep guidance regardless of which mattress you choose.
Pros:
- 4-inch profile is thinner than the other Newton models listed here.
- Washable cover and rinse-clean core.
- Two-stage design for infant and toddler use.
- GREENGUARD Gold certified for low emissions.
Cons:
- No waterproof layer is listed.
- Its thinner profile may not be right for every crib; verify fit requirements.
Verdict: Consider the Essential if you want Newton’s washable core in a thinner profile and do not need a built-in waterproof toddler side.
HALO DreamWeave: Best Lightweight Washable Option
HALO’s DreamWeave mattress has a breathable polymer core and a quilted mesh cover. Both the core and cover are washable: the cover is machine-washable, and the core can be rinsed clean. The company describes the core as mostly air and food-grade polymer, which also makes the mattress lightweight for sheet changes.
The dual-sided design provides a firm infant side and a waterproof toddler side. Its materials are listed as free of foam, glue, latex, springs, and flame retardants, and the mattress is GREENGUARD Gold certified. The product information also says the core is recyclable at the end of its use.
The toddler-side waterproofing is useful for later accidents, but it does not mean both sides have the same protection. The product details supplied here do not include mattress dimensions, so check the product listing and your crib manual to confirm a snug fit before use.
Pros:
- Washable cover and rinse-clean core.
- Waterproof toddler side in a dual-sided design.
- Lightweight core is designed to make sheet changes easier.
- GREENGUARD Gold certified and made without several listed materials.
Cons:
- Dimensions are not provided in the supplied product details, so verify fit before purchase.
- The waterproof protection is specified for the toddler side.
Verdict: The HALO is worth considering if you want an easy-to-clean, lightweight mattress with a distinct waterproof toddler side.
Naturepedic Organic: Best for an Organic Cotton Cover
Naturepedic takes a different approach from the breathable-core models above. It has a GOTS-certified organic cotton cover and a patented waterproof coating derived from sugarcane. The surface can be cleaned with soap and water, giving you a wipe-clean option without a separate washable inner core.
The product information lists a lightweight wave-support core weighing 11 pounds and a two-stage design for infant and toddler use. Its dimensions are approximately 27 1/4 by 51 5/8 by 6 inches, which differ from the 52-by-28-inch dimensions listed for the Newton models. Confirm the fit with your crib’s instructions rather than assuming all “standard” mattresses are interchangeable.
This mattress is a good match if certified organic cotton and a waterproof surface are priorities. It does not have the same rinse-clean breathable core as the Newton and HALO options, so the cleaning method is different. The product details list UL/GREENGUARD certification for low emissions.
Pros:
- GOTS-certified organic cotton cover.
- Waterproof coating can be wiped clean with soap and water.
- Lightweight 11-pound core makes sheet changes easier.
- Two-stage design for infant and toddler use.
Cons:
- Dimensions differ from the Newton models, so check crib compatibility carefully.
- The product information describes a wipe-clean surface rather than a rinse-clean inner core.
Verdict: Pick Naturepedic if organic cotton and a wipe-clean waterproof surface are more important to you than washing the mattress core.
How to Choose a Safe Baby Crib Mattress
Start with a Firm, Flat Sleep Surface
A crib mattress should provide firm, flat support and fit the crib as intended. Avoid adding toppers, pillows, loose blankets, or soft bedding to make the sleep surface feel more comfortable. A breathable label or material does not make a soft or poorly fitted sleep setup safe.
Measure for a Snug Fit
Check your crib’s manual for the mattress size and fit requirements, then compare them with the mattress dimensions. The products here do not all list identical measurements. A mattress that is too small can leave gaps, while a mattress that does not sit properly in the crib may not be a suitable choice.
Choose a Cleaning Method You Can Keep Up With
Newton and HALO describe washable covers and rinse-clean cores, which can help when messes reach beyond the surface. Naturepedic instead lists a waterproof coating that can be cleaned with soap and water. Think about whether you prefer to wash parts of the mattress or wipe the surface, and follow the care directions for your selected model.
Consider Waterproofing and the Toddler Stage
Some of these mattresses have a waterproof layer or coating, but the location and design vary. Newton’s waterproof model and the HALO list protection on the toddler side; Naturepedic lists a wipe-clean waterproof coating. If this feature matters, confirm exactly which surface is protected and when the manufacturer recommends using it.
Compare Materials and Emissions Information
Product certifications and material details can help you compare mattresses, but they do not replace checking the product label and care instructions. Newton and HALO list GREENGUARD Gold certification. Naturepedic lists GOTS-certified organic cotton and UL/GREENGUARD certification for low emissions. Choose based on the materials and certifications that matter to your family, without treating any one feature as a guarantee of safety.
Keep Safe-Sleep Habits in Place
Place your baby on their back on a firm, flat mattress with a fitted sheet, and keep the crib free of loose bedding and other soft objects. Follow safe-sleep guidance from your pediatrician and public health authorities. A mattress marketed as breathable does not prevent every sleep hazard and should not change these basics.
Frequently Asked Questions
Is a breathable crib mattress safer than a regular mattress?
Breathable designs may allow more airflow through the mattress material, but that feature alone does not establish that a mattress is safer or prevent suffocation. Choose a firm, flat mattress that fits your crib, and follow safe-sleep practices every time.
Can I use a mattress protector or topper?
Follow the crib and mattress manufacturers’ instructions. The sleep surface should remain firm and flat, with a fitted sheet that fits securely. Do not add a soft topper or other item that changes the intended sleep surface.
Are all of these mattresses waterproof?
No. The Newton waterproof model lists a waterproof layer on its toddler side, and HALO lists a waterproof toddler side. Naturepedic describes a waterproof coating that can be wiped clean. The other Newton models in this guide do not list a waterproof layer.
Can I wash the entire mattress?
The Newton and HALO product information says their covers can be machine-washed and their cores can be rinsed clean. Naturepedic lists a surface that can be cleaned with soap and water. Follow each manufacturer’s care directions and do not assume every mattress component can go in a washing machine.
Do two-stage mattresses need to be flipped?
A two-stage mattress has different sides intended for different growth stages, but the correct timing and orientation depend on the product. Follow the instructions included with your mattress rather than flipping it based on age alone.
How do I know whether a mattress fits my crib?
Check the crib manual for the required mattress dimensions and fit, then compare those details with the mattress specifications. The products in this guide have different listed measurements, so do not rely on a general “standard size” label alone.
Which mattress is the best choice for most families?
The Newton Baby Crib Mattress & Toddler Bed is a strong all-around option if you value a washable cover and rinse-clean core. If waterproofing is a priority, compare the Newton Waterproof, HALO, and Naturepedic models based on which surface is protected and how you prefer to clean it.
Final Recommendation
For families who want to clean both the cover and core, the Newton Baby Crib Mattress & Toddler Bed is a straightforward place to start. Choose the Newton Waterproof or HALO if a waterproof toddler side is important, or Naturepedic if an organic cotton cover and wipe-clean coating better fit your priorities. Whichever you select, confirm the crib fit and keep the sleep space firm, flat, and free of loose items.
