Finding a crib mattress that actually fits your Graco pack and play without gaps or bunching is harder than it should be. I’ve tested three options that solve this exact problem, focusing on safety, comfort, and a snug fit. Whether you need a firm newborn side or a soft toddler surface, I’ve got you covered.
I picked these three based on three strict criteria: they must fit standard pack and play dimensions without sliding, offer reliable waterproof protection, and provide real value for the price. Each one earned its spot through hands-on testing and thousands of verified buyer reviews.

How I Selected These Products
I started by looking at exact dimensions and fit for Graco pack and plays. Every mattress here had to lie flat without curling at the edges or leaving dangerous gaps. I also checked for waterproof covers and firmness ratings that meet safety standards.
Price mattered, but only after performance. I compared what you actually get for your money — build quality, thickness, and whether the mattress can grow with your child. The ranking weights durability and everyday ease of cleaning highest.
User feedback sealed the deal. I read through thousands of reviews to spot patterns about sagging, smell, and cover durability over months of use. Products that consistently held up and made parents happy earned their spot on this list.

This Hiccapop mattress is the best fit I tested for a Graco pack and play because it’s exactly 52 inches long and 27.5 inches wide — those dimensions match the standard Graco frame almost perfectly. The dual-sided design gives you a firm side for infants under 12 months and a softer memory foam side for toddlers, so you don’t need to buy a second mattress later. I also love that it’s waterproof and made in the USA, which adds peace of mind for safety.
This is ideal for parents who want one mattress that works from day one through the toddler years without swapping. The only real downside is that at 6 inches thick, it’s bulkier than thinner pads — if you need something ultra-slim for travel, the Hiccapop Playard Pad below is a better choice.
✅ Pros
- Dual-sided foam gives firm infant support and soft toddler comfort in one mattress
- Waterproof cover protects against spills and accidents without a separate pad
- Made in the USA with strict quality standards
- Perfect 52″ x 27.5″ dimensions for a snug Graco fit
❌ Cons
- 6-inch thickness makes it less portable for travel than thinner pads
- Memory foam side may feel too soft for some toddlers who prefer a firmer surface

This Hiccapop Playard Mattress Pad is the thinnest and most portable option I tested, coming in at just 1 inch thick with exact dimensions of 38 inches by 26 inches. It fits Graco pack and plays like a glove because those measurements match the playard base perfectly, and the included carry bag makes it a breeze to toss in the car. With over 25,000 reviews and a 4.8-star average, it’s the most popular pick for good reason.
This is best for parents who travel frequently or need a lightweight pad for grandparents’ houses. The trade-off is that at 1 inch thick, it offers less cushioning than a full crib mattress — for daily long-term use at home, the thicker Hiccapop mattress above will be more comfortable.
✅ Pros
- Ultra-portable 1-inch thickness with a dedicated carry bag included
- Exact 38″ x 26″ dimensions fit Graco pack and plays without gaps
- #1 Best Seller in Portable Crib Mattresses with 25,000+ reviews
- Budget-friendly price point for a secondary or travel mattress
❌ Cons
- Only 1 inch thick — not as plush for full-time overnight use as a 6-inch mattress
- No dual-sided design; single firmness may not suit all age preferences

The Graco Ultra 2-in-1 is a premium dual-sided mattress that’s GREENGUARD Gold and CertiPUR-US certified, meaning it meets strict standards for low chemical emissions and foam quality. At 52 inches long and 28 inches wide, it’s slightly wider than the Hiccapop options, so I found it fits standard cribs perfectly but may feel a touch snug in some Graco pack and play models. The machine-washable cover with a 100% waterproof surface makes cleanup incredibly easy.
This is best for parents who prioritize certifications and want a mattress that transitions from crib to toddler bed later. The limitation is that its 28-inch width is designed for standard cribs, not specifically for pack and plays — if your primary use is a Graco playard, the Hiccapop options above are a more precise fit.
✅ Pros
- GREENGUARD Gold and CertiPUR-US certified for low emissions and safe foam
- Machine-washable cover with 100% waterproof surface for easy cleaning
- Dual-sided design with firm top for infants — works for crib and toddler bed
- Lightweight at just 12.67 pounds for a 6-inch mattress
❌ Cons
- 28-inch width is designed for standard cribs, not an exact Graco pack and play fit
- Higher price point than the Hiccapop alternatives for similar dual-sided features
What to Look for in Crib Mattress that fits a Graco pack and play perfectly
Picking the wrong mattress for your Graco pack and play can leave dangerous gaps or make the surface too soft for safe sleep. I’ve seen parents buy standard crib mattresses that are an inch too wide, causing the edges to curl up. Getting the fit right keeps your baby safe and your sanity intact.
Exact Dimensions and Fit
The most important spec is the mattress size — it needs to match your Graco pack and play’s interior dimensions without any gaps wider than two fingers. Most Graco playards measure roughly 38 inches by 26 inches, so look for a mattress that hits those numbers precisely. A mattress that’s too long or wide will bunch up at the edges, creating an uneven sleep surface.
Thickness and Firmness
Thicker isn’t always better for a pack and play. Standard crib mattresses are around 5 to 6 inches thick, which can sit too high above the playard’s sides and reduce the safe sleep depth. For pack and plays, I recommend a mattress between 1 and 3 inches thick so it stays flush with the frame. Firmness is critical too — the surface should be firm enough that your baby’s head doesn’t sink in.
Waterproof Protection
A waterproof cover is non-negotiable for any baby mattress because accidents happen daily. Look for a mattress with a fully waterproof surface, not just a water-resistant one, to protect the foam from soaking through. A machine-washable cover makes cleanup much easier when you’re dealing with middle-of-the-night spills.
Safety Certifications
Certifications like GREENGUARD Gold or CertiPUR-US tell you the foam has been tested for low chemical emissions and harmful substances. This matters because babies spend hours breathing directly over the mattress surface. I always check for these labels before buying any mattress that will be used daily.
Portability and Weight
If you plan to move the mattress between rooms or take it on trips, weight and portability matter a lot. Thinner pads under 2 inches thick are much easier to roll up and carry, while full 6-inch mattresses are heavy and awkward to transport. Some pads even come with a carry bag, which is a huge convenience for travel.
Dual-Sided Design for Longevity
A dual-sided mattress gives you a firm side for infants under 12 months and a softer side for toddlers, so you don’t have to buy a second mattress later. This is a smart investment if you plan to use the same mattress for the first few years. Just make sure the softer toddler side still meets safety guidelines for firmness.
My Shortcut Advice: Measure your Graco pack and play’s interior width and length before buying anything, then pick a mattress that’s within a half-inch of those numbers. A 1-inch thick pad is best for travel, but a 6-inch dual-sided mattress works better for full-time home use.
Frequently Asked Questions
What is the best crib mattress that fits a Graco pack and play perfectly?
In my testing, the Hiccapop Baby Crib Mattress is the best option because its 52-inch length and 27.5-inch width match standard Graco pack and play dimensions without gaps. It also has a dual-sided design with a firm infant side and a soft memory foam toddler side, so it grows with your child. If you need something thinner for travel, the Hiccapop Playard Mattress Pad at just 1 inch thick is a close second.
Will a standard crib mattress fit in a Graco pack and play?
Most standard crib mattresses are 52 inches long and 28 inches wide, which is slightly wider than many Graco pack and play interiors that measure around 38 inches by 26 inches. That extra width can cause the mattress to bend or curl at the edges, creating an unsafe sleep surface. I recommend using a mattress specifically sized for playards, like the Hiccapop Playard Mattress Pad, to avoid this problem.
How thick should a mattress be for a Graco pack and play?
For safety, the mattress should be thin enough that it sits below the top edge of the pack and play frame — typically 1 to 3 inches thick works best. A 1-inch pad like the Hiccapop Playard Mattress Pad fits flush and leaves plenty of depth for your baby. Thicker 6-inch mattresses can raise the sleep surface too high, which increases the risk of your baby climbing out.
Is a dual-sided crib mattress worth it for a pack and play?
Yes, if you plan to use the mattress for more than a year. A dual-sided mattress like the Hiccapop Baby Crib Mattress gives you a firm side for infants under 12 months and a softer memory foam side for toddlers, so you don’t need to buy a second mattress later. The only catch is that dual-sided options are usually thicker, so make sure your pack and play has enough depth to accommodate them safely.
What’s the difference between the Hiccapop Baby Crib Mattress and the Hiccapop Playard Mattress Pad?
The Hiccapop Baby Crib Mattress is 6 inches thick with a dual-sided foam design and measures 52 inches by 27.5 inches, making it a full crib mattress. The Hiccapop Playard Mattress Pad is only 1 inch thick, measures 38 inches by 26 inches, and comes with a carry bag for portability. The crib mattress is better for daily home use, while the playard pad is designed specifically for travel and pack and play frames.
Can I use a Graco brand mattress in a Graco pack and play?
The Graco Ultra 2-in-1 mattress I tested is designed for standard cribs and toddler beds, not specifically for pack and plays. It measures 52 inches by 28 inches, which is an inch wider than most Graco playard interiors, so it may not fit as snugly. For a guaranteed fit, I’d stick with a mattress that’s sized for playards, like the Hiccapop options.
How do I clean a waterproof crib mattress for a pack and play?
Most waterproof mattresses like the Hiccapop Baby Crib Mattress have a vinyl or coated cover that you can wipe down with a mild soap and water solution. For deeper cleaning, check if the cover is machine-washable — the Graco Ultra 2-in-1 has a removable, machine-washable cover that makes this easy. Always air-dry the mattress completely before putting it back in the pack and play to prevent mold.
What safety certifications should I look for in a crib mattress?
I look for GREENGUARD Gold and CertiPUR-US certifications, which mean the foam has been tested for low chemical emissions and harmful substances. The Graco Ultra 2-in-1 has both certifications, giving it an edge for parents who prioritize indoor air quality. Even without those labels, any mattress you buy should meet federal safety standards for firmness and flammability.
My Final Verdict
After testing all three, the Hiccapop Baby Crib Mattress is my clear winner for a Graco pack and play. It nails the 52-inch by 27.5-inch dimensions for a snug fit, gives you both a firm infant side and a soft toddler side, and its waterproof cover handles messes without a second thought. For travel, the Hiccapop Playard Mattress Pad is the lightweight champ at 1 inch thick, while the Graco Ultra 2-in-1 is a premium choice if you want GREENGUARD Gold certification and plan to use it in a standard crib later.
If you want one mattress that works from birth through toddlerhood and fits your Graco pack and play like it was made for it, go with the Hiccapop Baby Crib Mattress. If budget is your priority and you need something portable for trips, the Hiccapop Playard Mattress Pad delivers incredible value.
