Our Picks: Best Premium Foam Crib And Toddler Mattress reviews
1. Graco Premium Foam Mattress: Best for Easy-Care Protection
This Graco mattress pairs a flexible polyurethane foam core with a waterproof sleep surface and a removable cover that can be machine washed. Its listed dimensions are 52 by 28 inches, with a height of up to 4.5 inches. That lower profile may be useful if you need to check mattress height against your crib’s instructions and mattress-support settings.
The product information lists GREENGUARD Gold certification, UL formaldehyde-free validation, CertiPUR-US certified foam, and an OEKO-TEX Standard 100 certified cover. It is also described as fiberglass-free and made without chemical flame retardants. These certifications and material claims may matter if you are comparing emissions testing and materials, but they do not replace checking the mattress label and crib fit.
The removable cover is designed for cold, delicate-cycle washing and should be hung to dry; the instructions say not to use a dryer. That is a useful cleanup feature, though it means the cover may take longer to dry than one that can go in a machine dryer. The mattress ships compressed and may need up to 48 hours to expand fully.
Pros:
- Waterproof sleep surface and removable, machine-washable cover
- Several listed third-party certifications and testing claims
- Fiberglass-free construction, according to the product details
- Designed for use in a standard full-size crib and toddler bed
Cons:
- Cover must be hung to dry
- Listed height is up to 4.5 inches, so check compatibility with your crib
Verdict: Choose this Graco if a removable washable cover and clearly listed material certifications are priorities, and its height fits your crib.
2. Graco Ultra 2-in-1: Best for a Longer Listed Warranty
The Graco Ultra 2-in-1 is a foam mattress for a standard full-size crib or toddler bed. Its listed dimensions are 52 by 28 inches, with a height of up to 6 inches. The product is described as dual-sided, but the supplied details do not explain the specific feel or intended use of each side, so check the manufacturer’s instructions before flipping it.
Its removable cover has a waterproof sleep surface and can be washed in cold water on a delicate cycle. The care instructions say to hang it to dry and not to put it in a dryer. The foam is CertiPUR-US certified, and the mattress is described as GREENGUARD Gold and formaldehyde-free certified. The product details also say it is free of fiberglass and chemical flame retardants.
A 10-year limited manufacturer’s warranty is listed, though warranty coverage and conditions can vary, so review the current terms before purchasing. Like the other compressed models here, this mattress needs time to expand after delivery; the product information recommends allowing up to 48 hours at room temperature.
Pros:
- Waterproof, removable, machine-washable cover
- Listed GREENGUARD Gold and formaldehyde-free certifications
- CertiPUR-US certified foam
- 10-year limited manufacturer’s warranty is listed
Cons:
- Cover must be hung to dry
- Confirm the dual-sided design and the correct side for each stage using the product instructions
Verdict: This is a strong option if you want Graco’s washable waterproof cover and a listed limited warranty, provided its up-to-6-inch height suits your crib.
3. Modera Dual-Sided Mattress: Best for a Defined Two-Stage Design
Modera describes this 52-by-27.5-by-5.5-inch mattress as a two-stage design. One side uses high-density foam and is described as firm and flat for infants. The other has a memory foam layer intended for toddlers. Follow the product’s instructions about when and how to use each side, and use only a firm, flat infant sleep surface for a baby.
The mattress is covered in organic cotton and comes with a waterproof exterior protector that can be removed for machine washing. The product details say the mattress, cover, and related materials are CertiPUR-US certified. The smaller listed width compared with the 28-inch-wide Graco and Wonder Living models makes careful fit-checking especially important.
Its two distinct surfaces give this model a clearer stage-based design than the single-sided foam choices. On the other hand, memory foam on the toddler side may not appeal if you want one consistent feel throughout the mattress’s use. The product details do not specify drying instructions for the cover, so confirm those before washing.
Pros:
- Clearly described firm infant side and memory foam toddler side
- Organic cotton cover and removable waterproof protector
- Machine-washable protector for cleanup
- CertiPUR-US certification is listed for the mattress and related materials
Cons:
- Listed width is 27.5 inches, so check the fit against your crib
- Follow the maker’s guidance for switching sides and cleaning the cover
Verdict: Consider the Modera if you want a specifically described infant-and-toddler two-stage design and its dimensions match your crib.
4. Wonder Living Foam Mattress: Best for an Organic Cotton Cover
Wonder Living combines a premium foam interior with a removable 100% organic cotton cover. The mattress measures 52 by 28 by 5 inches and is listed for standard-size cribs and toddler beds. The cover is machine washable, which can make routine care simpler than a design that requires spot cleaning alone.
The product details say the mattress meets flammability, lead, phthalate, and CPSIA requirements and does not contain toxic flame retardants. They also cite federal flammability standards. The listing does not specify a waterproof surface, a reversible infant-and-toddler design, or foam certification, so shoppers who prioritize those features may prefer one of the Graco options or the Modera model.
The listed size is close to the dimensions of several other mattresses in this guide, but measurements alone do not guarantee a safe fit in every crib. Check the crib maker’s requirements and the mattress label. The product information also does not provide a drying method for the washable cover, so check its care label.
Pros:
- Removable 100% organic cotton cover
- Machine-washable cover
- Listed 52-by-28-inch size for standard cribs and toddler beds
- Product details state that it meets several safety-related testing requirements
Cons:
- Waterproof protection is not specified in the supplied product details
- Dual-sided construction and foam certification are not specified
Verdict: Pick Wonder Living if a washable organic cotton cover is your main priority and you do not need a documented waterproof surface or reversible design.
5. Tiankehan Foam Mattress: Best for a Simple Foam Design
Tiankehan describes this mattress as a premium foam model with a brushed fabric cover. The product title lists its size as 52 by 27.6 by 5 inches, while the description also refers to fitting cribs as large as 54 by 29.5 inches. Because those dimensions do not clearly match, confirm the exact mattress measurements and intended crib fit with the seller before buying.
The description says the foam is designed for support and stability, and that the fabric is breathable and moisture-absorbing. It also states that the mattress meets flammability, lead, phthalate, and CPSIA testing standards and contains no toxic flame retardants. The supplied details do not list a removable or waterproof cover, a foam certification, or a reversible toddler-and-infant construction.
This is a more basic choice than the Graco mattresses if you want a specified washable waterproof cover or multiple named certifications. Its simpler feature set may suit shoppers focused on a foam core, but the sizing discrepancy is important enough to resolve before placing it in a crib.
Pros:
- Foam construction with a brushed fabric cover
- Product details state that it meets several testing standards
- Listed 5-inch thickness
Cons:
- Product title and description give different fit dimensions
- Waterproof protection and a removable washable cover are not specified
Verdict: Consider Tiankehan only after confirming its exact dimensions and fit; shoppers wanting clearer sizing and care details may prefer another option in this guide.
How to Choose a Premium Foam Crib and Toddler Mattress
Check the fit against your crib
Start with the crib maker’s instructions, then compare them with the mattress’s exact length, width, and height. A mattress should fit snugly in the crib without gaps at the edges. Product descriptions may use broad phrases such as “standard size,” but the dimensions can still vary. This is especially important for the Tiankehan listing, which provides conflicting fit measurements, and for the Modera mattress, which is listed at 27.5 inches wide.
Look for a firm, flat infant sleep surface
For an infant, choose a firm, flat mattress that fits the crib correctly, and follow the mattress and crib instructions. A toddler comfort layer is not a substitute for the infant side. For a dual-sided design, confirm which side is intended for each stage and when the manufacturer says to flip it. Keep the sleep space free of loose bedding and extra padding.
Decide whether you want a single-sided or dual-sided design
A single-sided mattress has a simpler setup, while a two-stage mattress is designed to offer a different surface for toddler use. In this group, Modera describes a firm foam infant side and a memory foam toddler side. Graco calls its Ultra model dual-sided, but its supplied details do not describe the feel of each surface. Check the complete product instructions rather than assuming every reversible mattress works the same way.
Compare cover care and waterproofing
Accidents make cleanup features useful, but washable does not always mean dryer-safe. Both Graco models list removable waterproof covers that should be washed cold on a delicate cycle and hung to dry. Modera includes a removable waterproof protector that is machine washable. Wonder Living lists a washable cover but does not specify waterproofing in the supplied details. Tiankehan’s details do not list a removable or waterproof cover.
Understand what certifications and claims cover
Certification names can help you compare specific testing or material claims. The Graco Premium lists GREENGUARD Gold, UL formaldehyde-free validation, CertiPUR-US foam, and an OEKO-TEX Standard 100 cover. The Graco Ultra lists GREENGUARD Gold, formaldehyde-free certification, and CertiPUR-US foam; Modera lists CertiPUR-US certification. Check the product documentation for the scope of each claim, and do not treat a certification as a replacement for proper fit or safe sleep practices.
Plan for expansion and setup
The Graco mattresses ship compressed, and their product information recommends allowing up to 48 hours for expansion at room temperature. If you choose one, unpack it promptly and follow the provided setup instructions before use. Check the packaging and label for any other setup or care directions that apply to your model.
Frequently Asked Questions
What size crib mattress should I buy?
Use the dimensions and fit requirements in your crib’s manual, then compare them with the mattress’s listed measurements. Do not rely on a “standard size” label alone if the exact dimensions are available.
Are all five mattresses dual-sided?
No. Modera clearly describes a firm infant side and a memory foam toddler side, and the Graco Ultra is described as dual-sided. The other listings do not specify a reversible design. For any dual-sided model, check the manufacturer’s instructions for the intended use of each side.
Which options have waterproof protection?
Both Graco mattresses list waterproof sleep surfaces. Modera includes a removable waterproof protector. The supplied details for Wonder Living and Tiankehan do not specify waterproof protection.
Can I put a removable mattress cover in the dryer?
Follow the care instructions for your exact model. The Graco cover instructions say to hang it to dry and not to use a dryer. The supplied details do not specify drying instructions for the other washable covers, so check their care labels.
How long should a compressed mattress take to expand?
The Graco product details recommend allowing up to 48 hours at room temperature for full expansion. Follow the instructions that come with your specific mattress and check that it has expanded as directed before use.
Which mattress has the most clearly described toddler-stage surface?
Modera provides the clearest description in the supplied details: a firm foam infant side and a memory foam layer for toddlers. Graco Ultra is labeled dual-sided, but its supplied description does not explain the sides in detail. Confirm use instructions with the manufacturer.
Should I add a topper for more cushioning?
Do not add extra padding or a topper to an infant’s crib mattress. Use the mattress as directed by its manufacturer and keep the infant sleep surface firm, flat, and properly fitted to the crib.
Final Recommendation
For most shoppers comparing these five options, the Graco Premium Foam Mattress is the most balanced pick: it lists a waterproof washable cover, several material and emissions certifications, and a standard crib-and-toddler-bed fit. Choose the Graco Ultra if you value its listed limited warranty and up-to-6-inch profile, or Modera if you specifically want a clearly described two-stage design. Whichever you choose, verify the exact fit, follow the care instructions, and use the mattress according to its stage-specific guidance.
