Pack and Play Mattress Safety: Pad, Sheets and Extras
Quick Answer
Use the mattress pad supplied for your exact Pack ’n Play, installed and secured as its manual directs. Do not add a mattress topper, folded blanket or extra mattress to soften it. Use only an allowed fitted sheet. A missing or damaged pad needs a manufacturer-approved replacement for that model, not a similarly sized mini-crib mattress.
Our Verdict
Keep the correct original pad and approved fitted sheet, with no extra cushioning. If the pad is missing, damaged or cannot be identified, arrange another suitable sleep space while the manufacturer confirms the right replacement. Model compatibility matters more than a retailer’s “fits Pack n Play” claim.
Key Takeaways
- ✓A playard has flexible sides; a rigid-sided mini crib does not. Newton's mini-crib mattress guidance, updated June 26, 2026, says its mini-crib mattress is for stationary, rigid-sided mini cribs only.
- ✓Graco's On The Go Zip product support asks for the product's model number and manufacture date when looking up replacement parts. Collect both before contacting support.
- ✓A fitted sheet and a mattress topper do different things. The sheet should cover the approved pad as the model permits; it is not permission to add padding underneath.
- ✓On October 30, 2025, CPSC recalled Modera Organic Cotton Pack N Play mattresses. The aftermarket mattresses might not fit certain play yards adequately, creating a deadly entrapment hazard.
- ✓Limits belong to the mode, not the pad. For example, Graco's On The Go Zip product page ends bassinet use when the baby starts pushing up on hands and knees or exceeds 15 pounds, whichever comes first.

We researched manufacturer instructions and CPSC/AAP guidance for the original pad, replacement parts and added layers. Our home-playard guide handles choosing the playard itself.
The pad and the playard are one setup
A playard has flexible sides; a rigid-sided mini crib does not. Newton's mini-crib mattress guidance, updated June 26, 2026, says its mini-crib mattress is for stationary, rigid-sided mini cribs only. It warns that adding a supplemental mattress to a soft-sided playard can create a gap.
That is why “the dimensions look close” is not a compatibility check. Matching length and width does not answer whether the whole sleep setup is approved. If you are choosing between product classes, our Pack-n-Play, travel-crib and mini-crib comparison explains their different jobs.
The AAP's safe-sleep guidance calls for a firm, flat sleep surface in a crib, bassinet, portable crib or play yard meeting CPSC standards. It also keeps mattress toppers and other soft bedding out of an infant's sleep area. Adult comfort preferences are not the test for an infant sleep surface.
What are you trying to change? Use this decision table
| Your situation | Useful next step | Do not substitute |
|---|---|---|
| Original pad feels hard, but is intact and correctly installed | Keep the specified setup; review the manual | A topper, folded blanket or second mattress |
| Pad is missing | Find model/date label and ask Graco for the correct part | A marketplace pad selected only by size |
| Pad is torn, warped or otherwise damaged | Stop and ask the manufacturer about replacement | Extra cushioning to hide the damage |
| Sheet bunches or pulls up the pad | Remove it; confirm allowed sheet and fit | A larger sheet tucked under the edges |
| You want easier cleanup | Check allowed sheet and pad-care instructions | An unapproved padded protector |
| Bassinet mode is outgrown | Follow the mode-transition instructions | Another layer to change its height or fit |
This table is a decision aid, not a mattress-fit certification. An unresolved model, missing part or unclear instruction is a reason to contact the manufacturer before using the proposed setup for sleep.
Check the exact model before replacing anything
Graco's On The Go Zip product support asks for the product's model number and manufacture date when looking up replacement parts. Collect both before contacting support. Do not assume a pad from another Graco playard is interchangeable because the brand matches.
A useful message to the manufacturer is: “I have model ___, manufactured ___. The original pad is ___ . Which replacement part and sheet are approved for this model and sleep mode?” Include pictures of the label and pad attachments. This makes the question more precise than “Which Pack n Play mattress should I buy?”
If you inherited the playard, establish which pad came with it. A seller's memory, a carry bag label or an accessory listing cannot replace that confirmation. Keep an alternative suitable sleep space available while you resolve missing instructions or parts.
Sheets, protectors and a bare sleep space
A fitted sheet and a mattress topper do different things. The sheet should cover the approved pad as the model permits; it is not permission to add padding underneath.
The current On The Go Zip manual specifies a Graco sheet designed for the pad's dimensions if a sheet is used. Follow your own model's wording rather than importing that model's size or instructions to every playard.
If a sheet distorts the pad, comes loose or cannot be matched to the instructions, remove it and resolve the fit. Do not tuck a standard crib sheet around a smaller pad as a workaround. For a waterproof protector, look for explicit model permission; “waterproof” describes a material property, not approval for this sleep setup.
The AAP lists pillows, blankets, mattress toppers and non-fitted sheets among items to keep out of the baby's sleep area. Our safe-sleep environment checklist covers the rest of the room without treating accessories as necessary upgrades.
A real recall explains why retail availability is weak evidence
On October 30, 2025, CPSC recalled Modera Organic Cotton Pack N Play mattresses. The aftermarket mattresses might not fit certain play yards adequately, creating a deadly entrapment hazard. The recall instructed owners to stop using the affected mattresses and contact Modera for a refund.
The recalled product had sides labeled “infant” and “toddler.” Those labels did not make it suitable for the affected setups. The notice reported no incidents or injuries; it is evidence of a hazardous product recall, not proof of a death caused by that product.
If you already own an aftermarket mattress, check its exact brand and label against the CPSC notice. Absence from this one recall does not establish compatibility with your playard.
Checklist before the next sleep
Use this as a prompt to review the actual manual:
- Identify: correct playard, original or confirmed replacement pad, correct sleep mode.
- Assemble: frame and pad secured exactly as shown; no missing parts or damage.
- Cover: only the permitted fitted sheet, with no bunching or added cushioning.
- Clear: remove loose bedding, pillows and toys from the infant sleep area.
- Limits: check when the bassinet mode or full playard must stop being used.
Limits belong to the mode, not the pad. For example, Graco's On The Go Zip product page ends bassinet use when the baby starts pushing up on hands and knees or exceeds 15 pounds, whichever comes first. Do not treat a pad change as a way to extend bassinet use.
What most parents get wrong
The question “Is this mattress safe?” skips the setup it will go into. A mini-crib mattress can be intended for one product class while being wrong for a playard. Likewise, a replacement for a damaged original pad is a different decision from adding a comfort layer over a working one.
The bottom line
Keep the correct pad, install it properly and resolve missing or damaged parts with the manufacturer. A baby who dislikes the sleep setup needs a response that preserves that setup's instructions, not a softer aftermarket layer.
Can you use a pack and play without a mattress?
Do not use it for sleep without the pad the model requires. The thin supplied pad is the mattress surface. If it is missing, ask the manufacturer for the correct replacement.
Are pack and play mattress toppers safe?
Do not add one for infant sleep. Graco's cited manual prohibits extra padding, and AAP guidance keeps mattress toppers out of an infant's sleep space.
Will a mini-crib mattress fit a Pack ’n Play?
Do not decide by dimensions. Newton says its mini-crib mattress belongs in rigid-sided mini cribs, not soft-sided playards. Use the pad approved for the exact playard.
Can I add padding for an older baby?
Do not use age as permission to override the playard's instructions. Follow its pad, mode and child-use limits. If those no longer suit your child, choose an appropriate next sleep space.
