The Graco Pack 'n Play is the most popular playard in America — and one of the most common questions new parents ask is: "What mat fits inside it?"
The answer depends on which Pack 'n Play model you have. Graco makes over a dozen versions, and the interior dimensions vary.
Parents frequently ask us about Graco Pack 'n Play compatibility more than any other playard, and the good news is that finding the right mat is straightforward once you know the model.

What to Look for in a Pack 'n Play Mat
The included mattress pad in most Pack 'n Plays is thin — about 1 inch of basic padding over a hard board. It's fine for sleeping (per AAP safe sleep guidelines, firm is actually better), but for awake playtime, your baby deserves more cushioning.
Here's what matters in a playard mat:
Fit: The mat should lie flat without curling at the edges. A mat that's too large will bunch up, creating a tripping hazard and an uneven surface. A mat that's too small will slide around. Aim for a mat that's exactly the interior size or up to 1 inch smaller on each dimension.
Thickness: Inside a playard, your baby can pull up on the rails and fall from standing height (about 2-2.5 feet). A 1-inch or thicker memory foam mat provides meaningful fall protection. Thin EVA mats (0.4-0.6") won't absorb much impact.
One-piece construction: This matters even more inside a playard than on an open floor. In an enclosed space, puzzle pieces that separate become choking hazards with no adult hand immediately nearby. Always choose a one-piece mat for playard use.
Safety certifications: Your baby will be face-down on this surface during tummy time, breathing inches from the material. Look for CertiPUR-US certified foam and OEKO-TEX tested fabric. Why certifications matter →
According to the Consumer Product Safety Commission (CPSC), any additional padding used in a play yard should fit snugly with no gaps between the pad and the sides. For sleep, only the manufacturer's original firm mattress should be used.
Easy cleaning: Playard mats get hit with everything — spit-up, drool, diaper leaks, snack crumbs. A wipeable surface (microsuede or PU leather) beats a fabric cover you have to remove and machine wash.

Frequently Asked Questions
Can I leave the Pack 'n Play's original mattress pad under the Poco Koko mat?
We recommend removing the original pad and placing the Poco Koko mat directly on the hard base. Stacking two pads creates an unstable surface and changes the fit. For sleep time, switch back to the original firm pad per AAP guidelines.
Is it safe to use a thicker mat in a Pack 'n Play?
For supervised awake playtime, yes — a thicker mat improves cushioning for tummy time, crawling, and falls. For unsupervised sleep, the AAP recommends a firm, flat surface. We recommend using the Poco Koko mat for playtime and switching to the original pad for sleep.
My baby stands up in the Pack 'n Play and falls. Will this mat help?
Yes. A fall from Pack 'n Play rail height (about 24-28 inches) onto 1.3 inches of memory foam is significantly cushioned compared to falling onto the thin stock pad. The slow-rebound foam absorbs impact progressively rather than bouncing.
How do I clean the mat inside the Pack 'n Play?
Lift the mat out, wipe with a damp cloth, and place it back. The microsuede surface repels liquids — spills bead up rather than soaking through to the foam.
