A foam topper can add cushioning to a mattress, but it is not a safe way to make an infant’s sleep surface softer. For babies, follow safe-sleep guidance: use a firm, flat, noninclined mattress with a fitted sheet, and do not add a topper or other padding. The options below are best considered only for an older toddler’s bed or another suitable use, and the topper must fit securely without creating gaps. Check with your child’s health care provider if you are unsure.
Our comparison focuses on foam type, cover features, fit, and practical limitations. Product details and availability can change, so confirm the current listing and measurements before buying.

Our Picks: Best Foam Topper For Crib Mattress reviews
1. SJEUQOP High Density Foam Topper with Waterproof Cover
This SJEUQOP topper has a 2-inch solid high-density foam core and measures 27.5 by 52 inches. Its listing says the foam is CertiPUR-US certified and describes a removable fabric cover with a waterproof inner lining. The topper is compressed for shipping and may need 24 to 72 hours to regain its shape after opening.
The practical appeal is its straightforward design: a foam layer for an older toddler’s bed, plus a cover intended to help protect against spills. The listed size matches many standard crib mattresses, but a matching measurement alone does not ensure a safe fit. Check the mattress and topper together; do not use this product in an infant’s sleep space or use it by itself.
Compared with the gel memory foam option below, this topper uses high-density foam rather than memory foam. That may suit shoppers looking for a simpler foam layer, but the listing does not provide a detailed firmness measurement. Its cover is described as removable, though the supplied details do not specify whether it is machine-washable.
Pros:
- High-density foam core with a 2-inch profile
- Waterproof inner cover lining
- Listing states the foam is CertiPUR-US certified
- Standard-style 27.5-by-52-inch dimensions
Cons:
- Must be used with a mattress, not on its own
- Foam needs time to expand after unpacking
Verdict: Consider this SJEUQOP model for a compatible older toddler’s bed if you want a basic high-density foam layer and waterproof cover lining, but do not use it for infant sleep.
2. Pareler Bear Gel-Infused Memory Foam Topper
This 2-inch topper uses gel-infused memory foam and measures 27.5 by 52 inches. The listing describes a soft, breathable fabric cover, a waterproof liner, and a zip-off cover that can be machine-washed. It is intended to add cushioning to a normal, thick mattress rather than be used alone.
The removable cover is a useful feature for routine cleanup, and the listing says the foam is CertiPUR-US certified. It also claims the product is fiberglass-free and made without glue. Those are listing claims, so check the product details and care instructions before purchase. As with any foam topper, do not add it to an infant’s crib sleep surface.
This is the memory-foam choice in the group, while the SJEUQOP options use high-density foam. The supplied product information indicates that this listing is unavailable, so it may not be a practical choice unless availability changes. Also confirm the topper’s fit and the mattress’s thickness before considering it for an older toddler’s bed.
Pros:
- Gel-infused memory foam in a 2-inch layer
- Waterproof liner and removable, machine-washable cover
- Listing states the foam is CertiPUR-US certified
- Designed to be used on a thick mattress
Cons:
- Listing currently indicates that the product is unavailable
- Not designed to be used by itself
Verdict: This may suit shoppers seeking memory foam and an easy-to-remove cover, but its listed unavailability and the need for a careful fit make it a secondary option.
3. Milliard Ventilated Memory Foam Topper with Washable Cover
The Milliard topper is a 2-inch memory foam layer measuring 52 by 27 inches. Its product information lists a 2.5-pound foam density and aerating holes intended to support airflow. It also comes with a waterproof, washable cover, and the foam is stated to be CertiPUR-US certified.
A key limitation is explicit: the manufacturer says this soft topper is not intended for babies. That makes it a poor fit for an infant crib, regardless of its crib-size dimensions. For an older toddler’s bed, its narrower 27-inch width is worth comparing against the mattress carefully; the other listed options are 27.5 inches wide.
The aerating holes and washable cover are useful design details, but they do not change the need for a suitable underlying mattress or a secure fit. The product information says to allow 24 to 48 hours for expansion. This listing is also marked unavailable in the supplied product details, so check whether it can be purchased before planning around it.
Pros:
- 2-inch memory foam with ventilation holes
- Waterproof, washable cover
- Listing states the foam is CertiPUR-US certified
- Foam density is specified in the product details
Cons:
- Manufacturer says it is not intended for babies
- Listing currently indicates that the product is unavailable
Verdict: The Milliard may be worth considering for an older toddler only if it becomes available and its narrower dimensions fit the bed securely; it is not for infant sleep.
4. SJEUQOP Breathable High Density Foam Topper
This SJEUQOP model measures 52 by 27.5 by 2 inches and has a high-density foam core. Its listing describes the foam as CertiPUR-US certified and says the cover has a waterproof inner lining. Unlike the first SJEUQOP option, the supplied details specifically say the full cover can be removed and machine-washed.
That care feature could be convenient for an older toddler’s bed, especially when the cover needs regular cleaning. The topper ships compressed and is said to need 24 to 72 hours to return to its normal shape. Allow that time before checking its fit, and follow the product’s care directions.
The design is similar to the first SJEUQOP pick, so choosing between them may come down to the cover-care details and the exact listing. Neither should be used alone or added to an infant’s sleep surface. For an older toddler, verify that the topper sits flat and does not leave a gap around the edges.
Pros:
- High-density foam with a 2-inch profile
- Removable, machine-washable cover
- Waterproof inner lining
- Listing states the foam is CertiPUR-US certified
Cons:
- Needs a compatible mattress and should not be used alone
- May take up to 72 hours to fully expand
Verdict: Of the two SJEUQOP choices, this is the more convenient option if a removable machine-washable cover matters, provided it fits an older toddler’s mattress securely.
5. Motherly Haven High Density Foam Topper with Anti-Slip Base
Motherly Haven uses a single layer of high-density foam and measures 51.8 by 27.5 by 2 inches. Its listing highlights an anti-slip base and washable materials. The product is described as lightweight and portable, which may appeal to families who move a suitable toddler sleep setup between locations.
The anti-slip feature is intended to help the topper stay in place, but it should not replace a careful fit check. Compare its measurements with the mattress, and make sure it lies flat with no edge gaps. The product information does not specify a waterproof layer, so do not assume it offers the same spill protection as the SJEUQOP or Milliard covers.
Compared with the other options, this model puts more emphasis on staying in place and easy care than on a waterproof liner or a removable zip cover. The supplied description also does not state a foam certification. For infant sleep, do not use this topper; consider it only for an appropriate older-toddler setup.
Pros:
- Single-layer high-density foam
- Anti-slip base is designed to reduce shifting
- Washable materials
- Lightweight design described as portable
Cons:
- Waterproofing is not specified in the product details
- Exact dimensions differ slightly from a 52-inch-long topper
Verdict: Choose Motherly Haven if a washable design and anti-slip base are your priorities, but confirm the slightly different length and do not count on waterproof protection.
How to Choose a Foam Topper for a Crib-Size Mattress
Keep infant safe sleep separate from topper shopping
If the bed is for a baby, do not add a foam topper. A topper changes the sleep surface, even if it is marketed for a crib or described as supportive. Use a firm, flat, noninclined mattress with a fitted sheet, and keep the sleep space free of extra padding. The products in this guide should not be treated as infant sleep products.
Check the child’s age and intended use
Some listings use words such as “baby,” “crib,” or “toddler,” but those labels do not establish that a product is safe for an infant. One product here explicitly says it is not intended for babies. If you are considering a topper for an older toddler, make sure the bed and sleep setup are appropriate for your child’s age and follow the manufacturer’s guidance.
Measure the mattress, not just the bed frame
These products are close to standard crib-mattress dimensions, but they are not all identical. The listed sizes range from 27 to 27.5 inches wide, and the lengths range from 51.8 to 52 inches. Measure the mattress itself and compare all dimensions. A topper that is too small or shifts around can leave an unsafe gap; do not rely on a “standard size” label alone.
Consider foam type and the amount of cushioning
The SJEUQOP and Motherly Haven options use high-density foam, while the Pareler Bear and Milliard models use memory foam. The Pareler Bear listing also describes gel infusion, and Milliard lists ventilation holes. These design details help distinguish the products, but the supplied information does not provide comparable firmness testing. Do not choose a softer surface for an infant.
Look closely at the cover and cleaning instructions
A waterproof lining can help protect the foam from spills, while a removable, washable cover can make routine cleanup easier. The SJEUQOP breathable model and Pareler Bear option specify machine-washable covers. Motherly Haven describes washable materials but does not specify waterproofing. Check the care label and listing before washing, since cover construction and instructions can vary.
Allow for expansion and inspect the fit
Several foam toppers arrive compressed. The SJEUQOP listings say to allow 24 to 72 hours for expansion, while the Milliard listing says 24 to 48 hours. Follow the exact product instructions and inspect the topper once it has fully expanded. It should lie flat on a compatible mattress and should not be used alone.
Read certification and material claims carefully
Some listings state that the foam is CertiPUR-US certified. Treat this as a product-specific claim and verify the current listing if certification matters to you. Certification does not make a topper suitable for infant sleep, and it does not replace checking fit, care instructions, or the product’s intended use.
Frequently Asked Questions
Can I put a foam topper on an infant’s crib mattress?
No. Do not add a topper to an infant’s sleep surface. Use a firm, flat, noninclined mattress with a fitted sheet and follow safe-sleep guidance.
Are these toppers safe for newborns?
The product descriptions do not establish that these toppers are safe for newborns. One listing explicitly says its topper is not intended for babies. Do not use any of these products as added padding in an infant’s crib.
Can a crib mattress topper be used by itself?
No. The SJEUQOP and Pareler Bear listings say their toppers are intended for use with a mattress, not alone. A topper is not a replacement mattress.
Which option has a machine-washable cover?
The supplied details describe machine-washable covers for the Pareler Bear and SJEUQOP breathable models. Motherly Haven says its materials are washable, while the Milliard cover is described as washable. Check the current care instructions before cleaning.
Which topper has a waterproof cover?
The SJEUQOP listings describe a waterproof inner lining, Pareler Bear specifies a waterproof liner, and Milliard lists a waterproof cover. Waterproofing is not specified in the Motherly Haven details.
How long should foam take to expand after opening?
Expansion time depends on the product. The SJEUQOP listings specify 24 to 72 hours, and the Milliard listing specifies 24 to 48 hours. Follow the instructions that come with the specific topper.
What is the best foam topper for a crib mattress?
For an older toddler’s compatible bed, the SJEUQOP breathable model is a practical pick if you want high-density foam, a waterproof lining, and a removable machine-washable cover. For an infant, the safest choice is not to use a topper at all.
Conclusion
For an older toddler’s bed, the SJEUQOP breathable high-density foam topper stands out for its removable washable cover and waterproof lining, while Motherly Haven may appeal if an anti-slip base is a priority. Compare measurements carefully, confirm current product details, and use any topper only in a suitable setup for an older child. For an infant’s crib, skip the topper and keep the sleep surface firm, flat, and clear.
