The best mini crib mattress for most buyers is the Dream On Me Breathable 2-in-1 Portable/Mini Crib, with a 38 x 24 in footprint, square corners and a waterproof toddler-side cover. Newton is a better match if you want a washable core, while Delta Serta pairs a firm fiber core with a wipe-clean waterproof cover.

A mini mattress is only a good fit when its dimensions and thickness match your exact crib. For a broader comparison, see baby crib mattresses.

Measure the interior before you buy, and follow the crib maker's guidance for the sleep surface.

How we chose these mini crib mattresses

We compared stated dimensions, materials, cover care and features that affect everyday use. Our score weighs specs, features and buyer feedback against what you’re shopping for.

Fit comes first. A 38 x 24 in mattress is common among these picks, but the Newton measures 37.75 x 23.75 in, and Delta's folding crib includes a 37.5 x 23.25 in mattress.

Those differences matter in a compact frame, so check the mattress dimensions against the crib's own instructions.

We also separated mattresses from accessories and crib bundles. Biloban is a protector, and Delta Children Folding Portable Mini Baby Crib is a crib that includes a thin mattress.

Letmxiu is sized for a standard crib, so it is included as a clear example of why a size check matters.

For a broader look at frame sizes and styles, see our best baby cribs buying guide. If you need a firm surface, compare the options in best extra firm mini crib mattress.

Mini crib mattress picks by fit and care

The top-rated picks lead with dimensions that suit common compact cribs, while lower picks offer more specialized cleaning or foam features. Confirm your crib's exact requirements before choosing any of them.

1

Dream On Me Breathable 2-in-1 Portable/Mini Crib: Best for a wipe-clean two-sided surface

9.7/10Our score

• 38 x 24 x 3 in
• Breathflow infant side
• Waterproof toddler-side cover
• GREENGUARD Gold certified

A 3-inch mattress with square corners, a Breathflow infant side and a waterproof toddler side. Its reinforced cover wipes clean with mild soap and water.

See it on Amazon

Pros

• Two-sided design
• Waterproof cover
• GREENGUARD Gold certified

Cons

• Measure the crib interior before buying
• May need up to 72 hours to regain its full shape

Dream On Me is the most versatile match in this group for a 38 x 24 in mini crib because it combines a 3-inch profile with two sides and a wipe-clean cover. The white infant side uses Breathflow material, while the toddler side has a waterproof cover with lock-stitched seams.

The square corners are intended to help the mattress sit snugly in the crib. Dream On Me says the cover can be cleaned with mild soap and water, which avoids removing a cover for routine wipe-downs.

This mattress is GREENGUARD Gold certified, and Dream On Me says its mattresses are CPSC tested for flammability, phthalates, lead and toxicity. Those certifications and claims do not replace checking the crib fit.

Choose it if your crib calls for a 38 x 24 in mattress and you want two distinct surfaces. The brand notes that a compressed mattress may need 24 to 72 hours to regain full shape, depending on room conditions.

2

Delta Children Folding Portable Mini Baby Crib: Best for a crib-and-mattress set

9.6/10Our score

• Crib includes a 37.5 x 23.25 x 1.5 in mattress
• Folds flat for storage
• Casters for mobility
• Two mattress-height positions

This pick is a folding mini crib bundled with its own 1.5-inch mattress, so it is most useful if you need the crib as well. The included mattress stores inside the crib when folded.

See it on Amazon

Pros

• Mattress is included
• Folds flat
• Two mattress-height positions

Cons

• Included mattress is 1.5 in thick
• Not a standalone replacement mattress

Delta Children Folding Portable Mini Baby Crib is a crib-and-mattress set, not a standalone replacement mattress. Its included mattress measures 37.5 x 23.25 x 1.5 in and stores inside the crib when the frame folds flat.

The crib has casters for mobility and two mattress-height positions. Its compact dimensions are 39 x 25 x 37.25 in, so it may suit a small room or travel setup where folding storage matters.

Delta says the crib is JPMA certified and tested to meet or exceed CPSC and ASTM standards. The included mattress size is specific to this crib, so don't assume a different 38 x 24 in mattress is interchangeable.

Choose this set if you need a folding mini crib with its own mattress. If you already own a mini crib and need a replacement surface, compare the fit of a standalone mattress instead.

3

Biloban Mini Crib Mattress Protector Sheets Waterproof: Best for a spare waterproof protector

9.6/10Our score

• Two 38 x 24 in protectors
• Waterproof
• Machine washable and dryable
• Four-layer design

This is a two-pack of waterproof mattress protectors, not a mattress. The extra cover lets you have one ready while the other is in the wash.

See it on Amazon

Pros

• Two protectors in the pack
• Waterproof
• Machine washable and dryable

Cons

• Measure the mattress before buying
• Adds a padded layer over the mattress

Biloban is a waterproof protector two-pack, not a mattress. Each protector measures 38 x 24 in, and the machine-washable design means you can rotate one while the other is being cleaned.

The brand describes a four-layer construction with absorbent fabric. A protector adds a layer above the mattress, so check how it fits with your crib sheet and whether the mattress maker allows one.

Choose it to keep a spare washable layer on hand for a compatible 38 x 24 in mattress. It does not change the size or thickness of the mattress underneath.

4

Letmxiu Premium Crib & Toddler Mattress: Best for a standard-size crib

9.6/10Our score

• Advertised for 54 x 29.5 in cribs
• Memory foam fill
• 5 in thick
• Not sized for a mini crib

This is a standard-size crib and toddler mattress, not a mini crib mattress. Its stated 54 x 29.5 in fit makes it a poor choice for a compact crib.

See it on Amazon

Pros

• Advertised for standard-size cribs
• 5 in thick

Cons

• Does not fit a typical mini crib
• Product dimensions also state 52 x 27.6 x 5 in

Letmxiu is made for standard cribs and toddler beds, so it is not a mini crib choice. The product dimensions are given as 52 x 27.6 x 5 in, while its fit description refers to 54 x 29.5 in cribs.

That size difference reinforces why you should check the actual interior measurements and mattress guidance for your own crib. A standard mattress is far too large for the mini crib dimensions common in this roundup.

Choose it only if you have a compatible standard crib, not a mini crib. For help distinguishing crib sizes, compare Newton mini crib mattress dimensions and the Nestig Wave crib mattress size.

5

Dourxi Mini Crib Mattress: Best for a removable washable cover

8.8/10Our score

• 38 x 24 x 4 in
• Dual-sided foam
• Removable machine-washable cover
• Not for playards

A 4-inch mattress made for mini cribs with a 38 x 24 in interior. Its zip-off cover can go in the washing machine, and the maker describes different foam sides for infants and toddlers.

See it on Amazon

Pros

• Removable washable cover
• Two foam sides
• Dimensions are stated clearly

Cons

• Not compatible with 38 x 26 in playards
• Allow at least 72 hours for expansion

Dourxi is a 4-inch mattress made for a mini crib with a 38 x 24 in interior. It has two foam sides: high-density support foam for infants and gel-infused memory foam for toddlers, as described by the brand.

Its cover unzips and is machine washable. Dourxi says the mattress is not compatible with standard 52 x 28 in cribs or 38 x 26 in playards, which makes measuring especially useful if you are comparing a mini crib and a portable playard.

Choose it if a removable washable cover matters and your crib calls for a 38 x 24 in surface. Allow at least 72 hours for the compressed mattress to expand in a room-temperature space.

6

Delta Children Serta SleepTrue Mini Crib Mattress: Best for a firm fiber core

8.7/10Our score

• 38 x 24 x 4 in
• Firm recycled polyester fiber core
• Waterproof vinyl cover
• GREENGUARD Gold certified

This 4-inch mattress pairs a firm fiber core made with upcycled plastic bottles with a waterproof vinyl cover. Delta says it fits most mini and portable cribs, but recommends measuring first.

See it on Amazon

Pros

• Firm fiber core
• Waterproof cover wipes clean
• GREENGUARD Gold certified

Cons

• Not designed for standard cribs or playards
• Check the crib's interior size

Delta Children Serta SleepTrue offers a 4-inch profile with a firm fiber core made from upcycled plastic bottles. Its waterproof vinyl cover is designed to wipe clean, and the mattress is GREENGUARD Gold certified.

Delta says the mattress fits most mini and portable cribs, but it is not designed for standard cribs or playards. Measure the interior rather than relying on a general label, especially if your crib came with a mattress in a different size.

The brand describes the cover as hypoallergenic and says the mattress meets or exceeds specified flammability, lead, phthalate and CPSIA testing. It also provides a 10-year warranty.

Choose it if you prefer a firm fiber core and a wipe-clean cover. Its 38 x 24 x 4 in size suits only cribs that approve those dimensions and thickness.

7

Moonlight Slumber Little Dreamer Mini Crib Mattress: Best for two firmness sides

8.6/10Our score

• 38 x 24 x 5 in
• Two-sided design
• Waterproof stretch-knit cover
• GREENGUARD Gold certified

The 5-inch mattress has a firm infant side and a softer toddler side, according to Moonlight Slumber. Its cover resists moisture and can be wiped clean.

See it on Amazon

Pros

• Two firmness sides
• Moisture-resistant cover
• Made with CertiPUR-US foam

Cons

• Confirm the crib allows a 5 in mattress
• Care instructions call for a damp sponge and warm soapy water

Moonlight Slumber Little Dreamer Mini is the thickest option here at 5 inches, with a firm infant side and a softer toddler side. The brand says it is designed for hard-sided mini cribs and uses CertiPUR-US foam.

Its medical-grade stretch-knit cover resists moisture and allergens. Moonlight Slumber recommends a damp sponge and warm soapy water for cleaning, rather than diaper wipes or household cleaning wipes.

At 38 x 24 x 5 in, this mattress needs a crib that allows that thickness. Choose it if you want a two-sided 5-inch mattress and your crib maker approves that profile.

8

Newton Baby Mini Crib Mattress 37.75" x: Best for a washable core

8.4/10Our score

• 37.75 x 23.75 x 3 in
• Removable washable cover and core
• Wovenaire core
• Mini cribs only

Newton's mini mattress measures 37.75 x 23.75 x 3 in and has a removable cover and core. It is for mini cribs, not standard cribs, play yards or soft-sided cribs.

See it on Amazon

Pros

• Cover and core can be cleaned separately
• Dimensions suit some compact crib interiors
• GREENGUARD Gold certified

Cons

• Smaller than a nominal 38 x 24 in mattress
• Confirm compatibility with your exact crib

Newton's mini mattress measures 37.75 x 23.75 x 3 in and has a Wovenaire core. Its cover can be washed, and the removable core can be rinsed in a shower or tub, so the design supports more complete cleaning than a wipe-only cover.

Newton says the mattress fits most mini or portable cribs and names several tested crib models, including Babyletto Origami and Gelato mini cribs and DaVinci Dylan. It is not intended for standard cribs, play yards or soft-sided cribs.

Choose it if washing the cover and core is a priority and the slightly smaller dimensions fit your frame. Read more about Newton mini crib mattress dimensions before comparing it with a crib that expects a full 38 x 24 in mattress.

9

VIVIDVIBEBEARPAS Mini Crib Mattress 38" x 24": Best for a 4-inch foam option

8.2/10Our score

• 38 x 24 x 4 in
• High-density foam
• Cotton cover
• Rounded corners

A 4-inch mini crib mattress with high-density foam and a cotton cover. The maker advises measuring because mini crib interiors can differ.

See it on Amazon

Pros

• Clear 38 x 24 in dimensions
• Cotton cover
• Rounded corners

Cons

• Allow 3 to 5 days for full recovery after unpacking
• Confirm fit with your crib

VIVIDVIBEBEARPAS is a 4-inch mini crib mattress with high-density foam and a cotton cover. The brand gives its dimensions as 38 x 24 x 4 in and advises measuring because crib interiors vary.

It also describes rounded corners and firm edges. After unpacking, the brand says the mattress may take 3 to 5 days to recover to normal use, so plan for that expansion time.

Choose it if you want a 4-inch foam option with a cotton cover and the dimensions match your crib. The maker describes its firmness as medium, so consider the fit and listed feel alongside the crib's own requirements.

What should you check before buying a mini crib mattress?

Measure the crib's inside length and width, then confirm the allowed mattress thickness in the crib manual. Mini crib dimensions can vary, and a mattress that is only slightly smaller may leave a gap around the edges.

Check how the corners meet the frame and whether the mattress sits flat. If you have a Nestig Wave or another named crib, use that model's mattress guidance; our Nestig Wave crib mattress size guide covers that specific frame.

Do not use a mini crib mattress in a playard unless the playard maker approves it for that exact model. For a broader comparison, read mini crib vs Pack N Play.

A mini crib mattress and playard mattress can have different dimensions even when both are called portable.

Which cover is easiest to clean?

A wipe-clean cover is simple for small spills, while a removable washable cover or core allows more thorough cleaning. Dream On Me and Delta Serta describe wipe-clean covers; Dourxi has a removable machine-washable cover, and Newton's cover and core can be cleaned separately.

A protector can add a washable layer, but it must fit the mattress and remain compatible with the crib's sleep surface requirements. Biloban's two-pack is sized for 38 x 24 in mattresses, so check the underlying mattress dimensions first.

Follow the care instructions for the exact model. Avoid adding extra padding or layers unless the crib and mattress makers allow them.

How do you choose between foam and fiber?

Choose based on the mattress construction, exact fit and care routine, rather than a material name alone. Delta Serta uses a firm recycled polyester fiber core, while Dourxi and VIVIDVIBEBEARPAS use foam constructions.

The thicknesses in this group range from 3 to 5 in for standalone mattresses. Make sure your crib allows the thickness, and use only the mattress surface and bedding that the crib maker recommends.

Which mini crib mattress should you choose?

Choose Dream On Me if you want a 38 x 24 in mattress with two sides and a wipe-clean cover; choose Newton if a washable core matters and its smaller dimensions fit your crib. Delta Serta is a firm fiber option, while Moonlight Slumber suits buyers whose crib accepts a 5-inch profile.

For a standard-size crib, skip mini models and check the frame's required size. If you're deciding whether a compact crib can later serve a toddler, see our guide to converting a mini crib to a toddler bed and our Dream On Me mini crib mattress reviews.

A safe fit starts with the crib maker's exact mattress dimensions and instructions. Measure first, then choose the cover and materials that fit your cleaning routine.

Frequently asked questions

How do I choose the best mini crib mattress?

Start with the crib maker's required mattress dimensions, then compare the mattress's length, width and thickness. A close label such as “mini crib” does not confirm fit.

After fit, choose by care needs: a wipe-clean cover is simple, while a removable washable cover or core can suit a laundry routine.

Are all mini crib mattresses the same size?

No. Many are around 38 x 24 in, but some are slightly smaller, and a bundled crib mattress can use different dimensions.

Measure the crib's interior and check the crib maker's mattress guidance before you choose.

Leave no gap around the mattress when it is in place.

Can I use a mini crib mattress in a playard?

Only if the playard maker specifies that mattress size for that model. A 38 x 24 in mini crib mattress does not match every playard, and Dourxi says its 38 x 24 in mattress is not compatible with 38 x 26 in playards.

Use only the sleep surface approved for your playard.

What thickness should a mini crib mattress be?

There is no single thickness that fits every mini crib. The products here range from 1.5 to 5 in, so check the crib's instructions for its approved mattress size and thickness before buying.

The included mattress for Delta's folding crib is 1.5 in thick.

How do I clean a mini crib mattress?

Follow the care instructions for the exact mattress. Some covers wipe clean, while Newton's cover is washable and its core can be rinsed; Dourxi's removable cover is machine washable.

A separate waterproof protector can add a washable layer, but check that it fits the mattress snugly.
