If you’re searching for the best co-sleeping mattress for baby, it helps to separate two ideas: sharing a room and sharing a bed. These products are crib mattresses, not mattresses designed for an adult bed or for bed-sharing. For a baby’s sleep, choose a separate, firm, flat surface made for an approved crib or bassinet, and follow current safe-sleep guidance. A breathable or washable mattress does not make bed-sharing safe.
Our picks below focus on crib mattresses that may suit families who want an easy-to-clean surface, a two-stage design, or a breathable core. Before buying, check that the mattress fits your crib as intended and follow the crib and mattress instructions.

Our Picks: Best Co Sleeping Mattress For Baby reviews
Newton Baby Crib Mattress: Fully Washable, Breathable-Core Design
This Newton Baby mattress is made for a standard-size crib and toddler bed. Its listed measurements are 52 by 28 inches, with a height of 5.5 inches. The main distinction is its Wovenaire breathe-thru core, which the maker says allows air to circulate through the mattress. It also has a removable cover and an inner core that can be rinsed clean.
The fully washable construction may be useful if you want to clean more than just the cover after a spill. The mattress is a two-stage model intended for use from infancy through the toddler years. It is also listed as GREENGUARD Gold certified. Keep in mind that breathability claims are not a substitute for safe-sleep practices, and this is still a crib mattress—not a product for placing in an adult bed.
Compared with the Newton Essential, this version is 1.5 inches thicker. That difference may matter when checking the fit and mattress-height settings in your crib. Measure and follow the instructions for your specific crib rather than assuming that a standard size will fit every model perfectly.
Pros:
- Removable cover and washable inner core
- Wovenaire breathe-thru core design
- Two-stage use for an infant and toddler bed
- GREENGUARD Gold certified, according to the supplied product information
Cons:
- Thicker than the Newton Essential, so check crib fit and setup instructions
- Breathable construction does not make bed-sharing safe
Verdict: Choose this Newton if full washability is your top priority and the 5.5-inch profile fits your crib. It is not intended for use as an adult-bed co-sleeping mattress.
Newton Baby Essential: A Lower-Profile Washable Crib Mattress
The Newton Baby Essential shares the core design and cleaning approach of the thicker Newton mattress. Its listed size is 52 by 28 inches, and it stands 4 inches high. The cover can be machine-washed, while the inner core can be rinsed in a shower or bath, according to the product description.
This model is also described as a two-stage crib and toddler mattress with a firm support surface. The thinner profile is its clearest difference from the other Newton pick. That can make it worth comparing if your crib’s instructions specify a particular mattress height or if you prefer a slimmer option. Always check the mattress fit and the crib manufacturer’s setup guidance.
The product information lists GREENGUARD Gold certification and describes the core as breathe-thru. Those features may appeal to parents who value a washable design and low-emission certification. However, no mattress design removes the need for a separate, properly set up infant sleep space.
Pros:
- Washable cover and rinse-clean inner core
- 4-inch profile, slimmer than the other Newton option here
- Designed for crib and toddler-bed use
- GREENGUARD Gold certified, according to the supplied product information
Cons:
- Check the thinner profile against your crib’s mattress and fit instructions
- Its breathable core should not be treated as protection against unsafe sleep arrangements
Verdict: The Newton Essential is a strong option to compare if you want Newton’s washable-core design in a 4-inch profile. Confirm that the height and fit are right for your crib before choosing it.
Serta Perfect Start Limited: Dual-Sided Support with a Waterproof Cover
The Serta Perfect Start Limited is listed as a dual-sided crib and toddler mattress with a waterproof cover. Its fiber core is made from recycled bottles, and the product description says the two sides are designed to support a baby and then a growing toddler. It measures 52 by 27.5 inches and is 5.5 inches high.
The waterproof cover may make surface cleanup simpler than a mattress that requires more involved washing. This is a different approach from the Newton models: the Newton cores are described as washable, while this Serta model emphasizes a waterproof surface. It is listed as GREENGUARD Gold and JPMA certified, and the description says it meets applicable safety testing standards.
The product data lists Delta Children as the brand, although the product title names Serta Perfect Start. Check the listing details carefully when shopping. The mattress is designed for standard full-size cribs and toddler beds, but you should still check its dimensions against your crib and follow both manufacturers’ instructions.
Pros:
- Dual-sided design for crib and toddler-bed use
- Waterproof cover for easier surface cleanup
- Fiber core made with recycled bottles, according to the product description
- Listed as GREENGUARD Gold and JPMA certified
Cons:
- The cover is described as waterproof, but the product data does not say the full mattress is washable
- Brand naming in the supplied listing information is mixed, so confirm the exact product before ordering
Verdict: Consider this option if you want a dual-sided mattress with a waterproof cover and recycled-fiber core. It is less suited to shoppers who specifically want a fully washable inner mattress core.
Dream On Me Baby Zzz: Two Firmness Stages and a Washable Cover
The Dream On Me Baby Zzz is a dual-sided mattress with a firm infant side and a cushioned toddler side, as described by the manufacturer. Its water-resistant surface is intended to help protect against messes, and the cover can be removed and machine-washed. The listed size is 52 by 28 inches, with a 5-inch height.
This model ships compressed in a box. The product instructions say to unroll it on a flat surface and allow up to 72 hours for it to reach its full height. That expansion step is worth planning for before you need to use the mattress. The product is listed as GREENGUARD Gold certified and Baby Safety Alliance Verified, and it has a seven-year limited manufacturer’s warranty.
Compared with the Newton mattresses, the Baby Zzz offers a removable washable cover rather than a washable inner core. Compared with the Serta option, its product description gives more detail about the infant and toddler sides and the compressed delivery process. As with any crib mattress, check the fit and follow the product’s setup instructions.
Pros:
- Dual-sided design with a firm infant side and cushioned toddler side
- Removable, machine-washable cover and water-resistant surface
- GREENGUARD Gold certified and Baby Safety Alliance Verified, according to the product information
- Seven-year limited manufacturer’s warranty
Cons:
- Needs time to expand fully after unboxing
- The supplied details describe a washable cover, not a washable foam core
Verdict: The Baby Zzz is a practical choice if you want a two-stage mattress, a washable cover, and clear setup instructions. Allow time for expansion, and use it only in a compatible crib or toddler bed.
Beautyrest Silver Slumber Nights: Two-Stage Design with a Waterproof Cover
The Beautyrest Silver Slumber Nights is a dual-sided crib mattress with a firm infant side and a toddler side. The listed dimensions are 52 by 27.5 inches, with a height of 5.5 inches. Its cover is described as waterproof, and the mattress uses a foam core blended with plant-based soy.
The product description also mentions Natural Silver Technology on the toddler side, intended to help prevent odor. It is listed as GREENGUARD Gold and CertiPUR-US certified, and the description says it does not contain toxic fire retardants. These features may be worth comparing if you want a two-stage mattress with a waterproof cover.
The supplied product data marks this mattress as unavailable. That status can change, so check the listing before making plans to buy. If it is not available, the Serta and Dream On Me options above also offer dual-sided designs, though their materials and care details differ.
Pros:
- Dual-sided design for infant and toddler use
- Waterproof cover for easier cleanup
- Listed as GREENGUARD Gold and CertiPUR-US certified
- Plant-based soy blended into the foam core, according to the product description
Cons:
- Listed as unavailable in the supplied product information
- The product details do not describe a removable, machine-washable cover
Verdict: This mattress may be worth considering if it becomes available and you want a dual-sided model with a waterproof cover, but compare its fit and care instructions with available alternatives first.
How to Choose a Mattress for Your Baby’s Sleep Space
Choose a separate sleep surface, not an adult-bed mattress
These picks are designed for cribs and toddler beds. They are not made to turn an adult bed into a baby sleep space, and a crib mattress should not be placed on top of an adult mattress. If you want your baby close by, consider room-sharing with the baby in a separate crib, bassinet, or other approved infant sleep space. Follow safe-sleep guidance from your pediatrician and trusted health authorities.
Check the fit and the crib instructions
A mattress should be made for the specific type of crib or toddler bed you use. Compare the product’s length, width, and height with the crib manufacturer’s instructions. The models in this guide are close in length and width, but their listed heights range from 4 to 5.5 inches. Do not rely on a general “standard size” label alone; confirm the fit and use the mattress as directed.
Look for a firm, flat surface for infant use
For an infant, use the mattress in the position and setup recommended by the crib and mattress makers. Do not add toppers, pillows, loose blankets, or other soft items to the sleep space. A product’s breathable materials, certifications, or marketing language should not replace a firm, flat sleep surface and safe-sleep practices.
Compare cleaning methods
Cleaning features vary across these mattresses. The Newton models describe a washable cover and rinse-clean inner core. The Serta and Beautyrest descriptions emphasize waterproof covers, while Dream On Me lists a water-resistant surface and removable machine-washable cover. Think about what you want to clean and check the care instructions before buying. Waterproof and water-resistant are not the same claim, and neither means every part of a mattress can be washed.
Decide whether you need a two-stage mattress
Several options have separate infant and toddler sides. A two-stage design can be convenient as your child moves from a crib to a toddler bed, but you should follow the manufacturer’s instructions for when and how to flip the mattress. The Newton, Serta, Dream On Me, and Beautyrest products are described as two-stage or dual-sided choices.
Understand certifications and product claims
Some products in this guide list GREENGUARD Gold certification, and the Serta, Dream On Me, and Beautyrest descriptions include other certification or verification details. These are useful points to compare, but certifications do not guarantee that a mattress prevents injury or makes an unsafe sleep arrangement safe. Read the product information and use the mattress only as intended.
Plan for delivery and setup
The Dream On Me mattress ships compressed and may take up to 72 hours to expand to its stated height, according to its product details. If you choose a mattress that arrives compressed, allow time for setup and inspect it according to the included instructions before use. For other models, follow the manufacturer’s care and setup guidance as well.
Frequently Asked Questions
Is it safe to put a baby on a mattress in an adult bed?
No. These products are crib and toddler-bed mattresses, not adult-bed co-sleeping mattresses. Use an infant sleep surface designed for its specific crib, bassinet, or play yard, and follow safe-sleep guidance. A crib mattress should not be placed on an adult bed.
Does a breathable mattress make bed-sharing safe?
No. A breathable-core claim does not make bed-sharing safe or remove the risks of an adult sleep surface. The Newton mattresses in this guide are designed for cribs and toddler beds. Use them only as intended by the manufacturer.
Which mattress is easiest to clean?
The Newton models describe both a washable cover and a rinse-clean inner core. Dream On Me has a removable, machine-washable cover, while the Serta and Beautyrest descriptions emphasize waterproof covers. Check each product’s care instructions to see which approach fits your needs.
Are these mattresses suitable for a standard crib?
The product descriptions list these models as intended for standard full-size cribs or toddler beds. Their exact measurements differ, so check the fit against your crib’s instructions before buying. A close fit is important; do not assume every mattress will work with every crib.
What does a two-stage crib mattress mean?
A two-stage mattress has different sides intended for infant and toddler use. For example, Dream On Me describes a firm infant side and a cushioned toddler side. Follow the manufacturer’s guidance on when to flip the mattress and how to use each side.
Is the Beautyrest Silver Slumber Nights mattress available?
The supplied product information lists it as unavailable. Availability may change, so check its product listing. If you need another dual-sided option, compare the Serta Perfect Start Limited and Dream On Me Baby Zzz mattresses.
Which mattress should I choose if I want an easy-care option?
If you want to clean the inner core as well as the cover, compare the Newton mattresses. If a removable washable cover or waterproof surface is more important, look at Dream On Me or the Serta option. Make the final choice based on crib fit, care instructions, and the features you will use—not on a mattress’s ability to make bed-sharing safe.
Final Recommendation
For a crib or toddler bed, the Newton Baby Crib Mattress stands out for its washable cover and inner core, while the Newton Essential offers a thinner profile with a similar cleaning approach. Choose the Serta or Dream On Me if a dual-sided design matters more, and consider Beautyrest only if it is available and suits your needs. None of these products is designed for adult-bed co-sleeping. For your baby’s sleep, use a separate, properly fitted infant sleep surface and follow safe-sleep guidance.
