The best crib mattress for newborn babies is the Delta Children Serta Perfect Slumber because it combines a firm fiber core, a waterproof cover on both sides and standard crib dimensions. Graco is a close alternative if machine-washing the cover matters most.
A newborn mattress should fit the crib tightly, stay firm and allow simple cleanup. Measure the crib before ordering, then compare the mattress dimensions with the crib manufacturer's fit requirements.
If you're still comparing materials, use this crib mattress comparison guide to review foam, fiber and coil designs. Our score weighs specs, features and buyer feedback against what you're shopping for.
Fit matters more than brand preference in the first months. A gap at the side or a sheet that pulls tight can change how the mattress sits, so check both length and width before you buy.
This guide is built around that daily reality. We look at firmness for newborn support, waterproofing for night spills, and whether the care steps fit a normal household routine.

Which crib mattress is best for a newborn?
The Delta Children Serta Perfect Slumber is the best overall newborn crib mattress in this group. It has a firm fiber core, a 52 x 27.5 x 5 in size, a waterproof vinyl cover on both sides and a square-corner design for a secure standard-crib fit.
Graco is the best choice when removable, machine-washable cover care is your priority. Sealy is the main coil option, while Dream On Me Serene Snooze is a strong fit for parents who want an extra-firm infant side.
Review the crib mattress safety checklist before setting up the sleep space. A mattress should sit flat and leave no unsafe gaps around the edges.

The products below are ordered by score, with the highest-scoring newborn crib mattress first. Each one solves a different fit, care or support need.
Delta Children Serta Perfect Slumber Dual Sided Crib: Best for most newborns
- Firm fiber core
- Waterproof vinyl cover on both sides
- GREENGUARD Gold certified
- 52 x 27.5 x 5 in
A firm fiber-core mattress with a waterproof cover on both sides. Its standard crib and toddler-bed dimensions make it a practical newborn-to-toddler choice.
Pros
- Firm support
- Waterproof on both sides
- GREENGUARD Gold certified
- Made in USA
Cons
- Requires 24–72 hours to regain full shape
The Delta Children Serta Perfect Slumber is the strongest all-around pick for a newborn. Its firm fiber core measures 52 x 27.5 x 5 in, which matches the size used by many standard cribs and toddler beds.
The core is made from sustainably sourced fiber, and the cover is waterproof vinyl on both sides. For a model-specific comparison, see Newton Original vs Waterproof.
That two-sided cover lets you flip the mattress when your child moves from a crib to a toddler bed.
GREENGUARD Gold and JPMA certifications add useful information about the mattress's construction and emissions. Delta Children also describes the cover as hypoallergenic and says the mattress is made in the USA with a 7-year warranty.
Allow 24–72 hours for the mattress to regain its full shape after delivery. Choose it if you want firm support, simple wipe-clean care and a dual-sided design.
Graco Premium Foam Baby Crib & Toddler Bed Mattress: Best for washable care
- Firm polyurethane foam core
- Removable machine-washable cover
- OEKO-TEX STANDARD 100 cover
- 52 x 27.6 x 4.5 in
Graco combines a firm foam core with a removable waterproof cover that can be machine washed. It fits standard full-size cribs and toddler beds.
Pros
- Machine-washable cover
- Firm foam core
- GREENGUARD Gold certified
- Fiberglass-free construction
Cons
- Cover must be hang dried
The Graco Premium Foam mattress is best for families who want a removable machine-washable cover. Its firm polyurethane foam core measures 52 x 27.6 x 4.5 in and fits standard full-size cribs and toddler beds.
The waterproof sleep surface blocks leaks, while the polyester cover can be removed and washed cold on a delicate cycle. Graco says to avoid bleach and hang the cover to dry rather than using a dryer.
The cover is OEKO-TEX STANDARD 100 certified, and the mattress has GREENGUARD Gold, CertiPUR-US and UL Formaldehyde Free validation. Its construction is fiberglass-free and does not use chemical flame retardants.
The mattress ships compressed, so allow up to 48 hours for full expansion at room temperature. Pick it when laundry convenience matters more than a vinyl cover that wipes clean without removal.
The 4.5-inch profile is thinner than several other picks, which helps keep the sleep surface lower in the crib. At 10.5 pounds it is also light enough to lift for sheet changes.
Care is the main trade-off to plan for. The cover must be hang dried, so leave a full drying window before you need the crib again.
Letmxiu Premium Crib & Toddler Mattress: Best for a 5-inch foam design
- 5-inch firm memory foam
- Knitted fabric and fleece surface
- 52 x 27.6 x 5 in
- Fits standard cribs and toddler beds
This 5-inch memory-foam mattress has a firm feel and a soft knitted fabric surface. It suits a standard crib that accepts its 52 x 27.6 in dimensions.
Pros
- 5-inch thickness
- Firm memory-foam core
- Soft knitted surface
- Fits standard cribs
Cons
- Needs 3–5 days before normal use
Letmxiu suits shoppers who want a 5-inch memory-foam design with a soft knitted fabric and fleece surface. It measures 52 x 27.6 x 5 in and is made for standard cribs and toddler beds.
The mattress has a firm feel and a memory-foam core. Its surface is described as breathable, quiet and non-toxic, which may appeal to families that prefer fabric over a vinyl sleeping surface.
Letmxiu says the mattress reaches about 90% to 95% of its shape within 72 hours and needs 3–5 days before normal use. Plan the setup early instead of placing it in the crib immediately after opening.
Choose this mattress when its 5-inch thickness and fabric surface fit your crib and care preferences. Measure the crib first because even a small size difference can affect the edge fit.
This style suits parents who want a fabric feel without a separate topper. It also suits rooms where a quiet surface matters during night changes.
The trade-off is the longer wait before use. If you are setting up the nursery close to a due date, factor in those days when you plan the delivery.
Dourxi Crib Mattress: Best for dual-sided foam
- Firm infant side and softer toddler side
- Gel and open-cell memory foam
- Removable washable cover
- 52 x 27.5 x 6 in
Dourxi offers a dual-sided design with a firmer infant side and softer toddler side. Its removable cover and 6-inch thickness make crib fit checks especially important.
Pros
- Dual firmness
- Removable washable cover
- CertiPUR-US certified foam
- Fits standard cribs
Cons
- Thicker than several picks here
Dourxi is the best dual-sided foam option for families planning to use one mattress from infancy through toddlerhood. The infant side is firmer and flat, while the toddler side uses a softer memory-foam surface.
Its 52 x 27.5 x 6 in size is thicker than most picks here. The mattress uses gel memory foam, open-cell memory foam and a high-density support core, so check the crib's allowed mattress height before ordering.
The removable cotton-blend cover can be washed, and CertiPUR-US certified foam is used in the construction. Dourxi also describes the cover as breathable and the mattress as suitable for standard cribs, convertible cribs and toddler beds.
Allow at least 72 hours for expansion after unboxing. Pick Dourxi if you want dual firmness and a washable cover, but confirm that the 6-inch thickness works with your crib.
The thicker build can help a fitted sheet sit more snugly, but it can also sit high in shallow cribs. Measure the rail height and sheet depth before you commit.
At 11.6 pounds it sits in the middle for weight, so regular sheet changes are manageable for most households.
Sealy Baby Flex Cool 2 Stage Crib and Toddler Bed Mattress: Best for coil support
- Firm infant side and softer toddler side
- 204 interwoven steel coils
- Cotton cover with airflow channels
- 52 x 28 x 5.75 in
Sealy uses an interwoven coil system with a firm infant side and softer toddler side. The cotton cover, waterproof barrier and reinforced edges support everyday crib care.
Pros
- Coil support
- Dual-stage design
- Waterproof PVC-free barrier
- GREENGUARD Gold certified
Cons
- Heavier than the fiber-core options
Sealy Baby Flex Cool is the best choice here for parents who prefer coil support. Its 52 x 28 x 5.75 in design uses 204 interwoven steel coils, with a firm infant side and a softer toddler side.
The cotton cover has airflow channels, and a PVC-free waterproof barrier helps protect against leaks. Reinforced border edges and corner pillars help maintain a flat sleep surface and keep the sheet fit secure.
Sealy includes GREENGUARD Gold certification and says the mattress is ASTM tested. The mattress is made in the USA and weighs 14.9 lb, so it may be less convenient to lift during sheet changes than lighter fiber-core models.
Choose it when a coil construction, cotton cover and dual-stage use matter to you. Compare the 5.75-inch thickness with your crib before buying.
Coils give a different daily feel from foam or fiber, with support that stays more even across the surface. That can suit parents who have used a coil mattress before and prefer that structure.
The heavier weight is the practical trade-off. It is still standard for a coil design, but it takes more effort to turn or lift for deep cleaning.
Dream On Me 2-in-1 Honeycomb Orthopedic Baby Crib Mattress: Best for simple wipe-clean care
- 5-inch fiber core
- Waterproof vented vinyl cover
- 52 x 28 x 5 in
- GREENGUARD Gold certified
The Honeycomb uses a firm 5-inch fiber core and a waterproof vented vinyl cover. Its surface wipes clean with mild soap and warm water.
Pros
- Firm fiber support
- Waterproof cover
- Made in USA
- 10-year warranty
Cons
- Vinyl cover needs wipe cleaning rather than machine washing
Dream On Me Honeycomb is a practical option for parents who want a firm fiber core and wipe-clean cover. The mattress measures 52 x 28 x 5 in and uses a waterproof, vented vinyl cover.
The white honeycomb cover can be wiped with mild soap and warm water. That care routine is simple for small spills, but it doesn't offer the removable machine-washing available with the Graco mattress.
Dream On Me says the mattress is GREENGUARD Gold certified, meets flammability, phthalate and lead tests, and is made in the USA. It also carries a 10-year warranty.
Its dual-sided design works for infants and toddlers. Pick Honeycomb when basic waterproof care and a firm fiber core matter more than a washable outer cover.
The vented cover design adds a practical detail for everyday use. Wipe care means no long drying time after a spill, which helps when the crib is needed again the same night.
At 8 pounds in the product specs, it is lighter than coil options and easier to move for sheet changes. Square fit at 52 x 28 inches suits most standard cribs, but measure first.
Dream On Me 2-in-1 Serene Snooze Baby Crib Mattress: Best for extra-firm infant support
- Extra-firm infant side
- Dual-sided toddler surface
- Waterproof vinyl cover
- 52 x 28 x 5 in
Serene Snooze emphasizes an extra-firm infant side while retaining a toddler side for later use. The waterproof vinyl cover wipes clean with a damp cloth.
Pros
- Extra-firm infant side
- Dual-sided design
- Made in USA
- 10-year limited warranty
Cons
- Not designed for mini cribs or playards
Dream On Me Serene Snooze is the best option for parents seeking an extra-firm infant side. It measures 52 x 28 x 5 in and has a second toddler surface for later use.
The waterproof vinyl cover wipes clean with a damp cloth, while lock-stitched binding adds durability to the cover edges. Its polyester fiber core gives the mattress a firm, flat base.
GREENGUARD Gold and BSA certifications are included, and Dream On Me says the mattress meets 16 CFR 1632 and 1633 flammability standards. It is made in the USA and has a 5-year limited warranty.
This mattress fits full-size cribs and toddler beds, but not mini cribs or playards. Choose it when extra-firm infant support and a standard 52 x 28 in fit are your main priorities.
Extra-firm is a description of the infant side, not a reason to add padding on top. Keep the surface flat and use only a fitted sheet made for this size.
The dual-sided layout means you plan for a flip later, not a new purchase at toddler stage. That can simplify the transition when the crib becomes a toddler bed.
Delta Children Serta SleepTrue Mini Crib Mattress: Best for mini cribs
- Firm recycled-polyester fiber core
- Waterproof hypoallergenic vinyl cover
- 38 x 24 x 4 in
- GREENGUARD Gold certified
SleepTrue is sized for most mini and portable cribs rather than standard cribs. Its firm fiber core and waterproof vinyl cover suit newborn sleep spaces with a 38 x 24 in base.
Pros
- Designed for mini and portable cribs
- Firm fiber core
- Waterproof cover
- Hypoallergenic cover
Cons
- Not designed for standard cribs or playards
Delta Children Serta SleepTrue is the best newborn mattress for a mini or portable crib. Its 38 x 24 x 4 in dimensions are not intended for standard cribs or playards, so measure the crib base before ordering.
The firm core uses recycled polyester fiber, and the hypoallergenic vinyl cover is waterproof and easy to wipe clean. For a fitted sheet sized for a Babyletto mini crib, see Babyletto mini crib sheets.
GREENGUARD Gold certification and the stated flammability, lead, phthalate and CPSIA testing provide additional construction details.
The mattress weighs 3.9 lb, which can make sheet changes easier than with heavier coil designs. It also has a 10-year warranty.
Choose SleepTrue only when your crib requires the 38 x 24 in mini-crib size. For a standard crib, use one of the full-size options above.
The 4-inch thickness sits a little higher than a 3-inch mini option, which can affect sheet fit. Check your sheet depth and the crib rail height before you order.
Dream On Me Breathable 2-in-1 Portable/Mini Crib Mattress: Best for breathable mini-crib use
- Breathable infant side
- Waterproof toddler side
- 38 x 24 x 3 in
- Two CertiPUR-certified layers
This 3-inch mattress fits standard portable and mini cribs. Its infant side uses breathflow material, while the toddler side has a waterproof vinyl cover.
Pros
- Breathable infant side
- Waterproof toddler side
- Made in USA
- Square corners
Cons
- Not for playards
Dream On Me Breathable is another mini-crib option, with a breathable infant side and a waterproof toddler side. It measures 38 x 24 x 3 in and fits standard portable and mini cribs.
The infant side uses breathflow material, while the toddler side uses soft vinyl with lock-stitched seams. Two CertiPUR-certified layers support airflow and cushioned comfort.
The cover wipes clean with mild soap and water. Dream On Me says the mattress is GREENGUARD Gold certified, made in the USA and designed with square corners for a snug fit.
This mattress is not for playards. Pick it when you need a thinner portable-crib mattress and prefer a breathable infant-side surface.
At 3 inches thick, this is the thinnest option in the group. That low profile can help in compact cribs where mattress height is limited.
The two-sided design is useful for a short stay in a mini crib. You flip for the toddler side later, but the fit check for your exact crib base still comes first.
How firm should a newborn crib mattress be?
A newborn crib mattress should have a firm, flat sleep surface that does not sink around the baby's body. In this group, the firmest stated options include Delta Children Serta Perfect Slumber, Graco Premium Foam and Dream On Me Serene Snooze.
Dual-sided mattresses need careful use. Put the infant side up for a newborn, and only use the toddler side when the manufacturer's age or stage guidance says it is appropriate.
Our guide to the best firm baby crib mattresses compares firm support in more detail. Do not add a soft topper, loose pad or extra cushion over the mattress.
Firmness is about support under weight, not hardness to the touch alone. A flat fiber, foam or coil base that holds its shape helps keep the sleep surface even night after night.
For newborns, the infant side of a dual-sided mattress is the starting point. That side is designed to be flatter and firmer than the toddler side.
As your baby grows and rolls, stage guidance matters more than guessing by feel. Follow the maker's instructions for when to flip or move to a toddler bed.
Thickness also plays a role in how firm a mattress feels in daily use. A thicker design can sit higher, so fit and sheet tension should be checked together.
Avoid soft additions that change the surface. A topper or blanket under a baby can undo the support the mattress was designed to provide.
If you are unsure which side to use, check the label on the mattress first. Use the side marked for infants until the guidance clearly changes.
What should you check before buying a newborn crib mattress?
Check the crib's required mattress dimensions, the mattress thickness limit and the space around every edge. A mattress that is too small can leave gaps, while one that is too thick may change the fit of the fitted sheet and crib rails.
For standard cribs, the full-size options here measure about 52 x 27.5–28 in. Mini and portable cribs need a smaller mattress, such as the 38 x 24 in Delta Children or Dream On Me options.
Use the site's guide on how to compare crib mattress support types when choosing between fiber, foam and coil construction. The right material is the one that meets the crib's fit requirements and matches the care routine you can manage.
Avoid adding a wedge or riser under the mattress unless a qualified professional has given you specific advice. Read can you use a crib mattress wedge or riser before changing the mattress angle.
Are waterproof crib mattresses easier to clean?
Yes. A waterproof vinyl surface can usually be wiped clean after a spill, while a removable cover can be taken off for washing.
The Delta Children, Dream On Me Honeycomb and Dream On Me Serene Snooze mattresses use waterproof vinyl covers. Graco adds a removable, machine-washable cover, while Dourxi has a removable washable cover.
Follow each mattress's care instructions and let washed covers dry fully before putting them back on. Keep a fitted sheet that matches the mattress size so the surface stays smooth.
Wipe-clean covers suit fast night care. You can clean a spill, let the surface dry, and return the crib to use without waiting for laundry.
Removable covers suit deeper cleaning. The trade-off is drying time, especially when the care steps say to hang dry instead of using a dryer.
A fitted sheet is still the first layer for daily use. It protects the surface and keeps spills from reaching the cover in the first place.
Check the sheet size against the mattress thickness. A sheet that is too shallow can pull up at the corners and leave the cover exposed.
For washable covers, use the cycle and temperature stated by the maker. Gentle care helps the cover keep its fit after repeated washing.
Let any washed cover dry completely before refitting. Putting it back damp can leave moisture trapped under the sheet.
Can a newborn use a vibrating crib mattress?
A newborn should sleep on a firm, flat mattress without added movement unless your pediatrician or the product instructions clearly support a specific setup. A vibrating feature is not required for a safe crib sleep surface.
Read can you use a vibrating crib mattress before adding vibration to a crib. If your baby has ongoing sleep or health concerns, ask a pediatrician for advice.
Vibration changes how a mattress sits in the crib. It can shift the surface and make the fit less stable than a still, flat setup.
That is why product instructions and medical advice matter here. A feature that is built in is different from adding movement after purchase.
For most newborns, a firm mattress and a fitted sheet are enough. Keep the surface clear of loose items and extra padding.
If sleep is difficult, talk with a pediatrician before trying new equipment. They can consider your baby's age, health and development.
Do not use vibration to replace a firm sleep surface. The mattress still needs to meet the crib fit and firmness guidance on its own.
What size mattress fits a mini crib?
Most mini-crib mattresses in this comparison measure 38 x 24 in, but you should confirm the exact crib dimensions first. Delta Children Serta SleepTrue is 4 in thick, while Dream On Me Breathable is 3 in thick.
Do not assume a mini-crib mattress fits a playard. The Dream On Me Breathable mattress specifically is not for playards, and SleepTrue is not designed for playards or standard cribs.
For another compact-crib reference, see the guide to Newton mini crib mattress dimensions.
Mini cribs vary more than standard cribs, so measuring is not optional. Measure the inside length and width, then compare both numbers with the mattress size.
Thickness matters in a smaller crib as well. A 4-inch mattress sits higher than a 3-inch one, which affects the fitted sheet and the rail height.
Square corners help the mattress sit closer to the crib walls. Even so, check for gaps on all four sides after you place it.
A mattress that is too small can leave unsafe space at the edges. A mattress that is too large should not be forced in.
Playards are a separate category with their own fit rules. Do not use a mini-crib mattress there unless the maker states it is compatible.
When in doubt, trust the crib maker's dimensions over a general size label. That check takes a minute and prevents a poor fit.
How to choose the best crib mattress for newborns
Choose the Delta Children Serta Perfect Slumber if you want the best balance of firm fiber support, waterproof care and standard-crib fit. Choose Graco Premium Foam if a removable machine-washable cover is more useful to you.
Pick Sealy Baby Flex Cool for coil construction, Dourxi for dual-sided foam, and Dream On Me Serene Snooze for an extra-firm infant side. For a mini crib, choose between SleepTrue and Dream On Me Breathable only after measuring the crib base.
The safest choice is the mattress that fits tightly, stays firm and supports a simple care routine. Recheck the dimensions before ordering, especially for mini cribs, portable cribs and thicker 6-inch designs.
