The pack and play pad that came in the box is almost always firm enough, and the fact that it feels thin and hard is not a defect. It is the design. Parents on BabyCenter, What to Expect and Glow keep asking the same question, and the honest answer is that you should only replace an original pad when it is lost, torn, or the wrong size for your specific playard.
That said, plenty of people want something firmer, better made, or simply not the cheapest possible slab of foam. Those pads exist, and the differences between them are real: thickness, cover fabric, foam density, and whether the pad carries a stated compliance figure. This roundup covers eight of them and sorts them by the thing the keyword actually asks about, which is firmness.
We compared every pad below on the details a parent can verify at home rather than on brand names. Every one is 38 x 26 inches unless noted, every one is a flat sleep surface rather than a cushioned topper, and each is rated on how it actually behaves when you press it. If you are still setting up the playard itself, start with our baby play mat guide for the floor-level alternative, then come back here for the sleeping surface.

1. Hiccapop Playard Mattress Pad 1.25 Inch – Best Overall Firm Fit
Hiccapop Playard Mattress Pad, Pack and Play Mattress with Carry Bag, 1.25″
38 x 26 x 1.25 inch
Firm 3-layer polyurethane foam
2.5 pounds
Meets F2933-21
Pros
- Firmest rated surface in this roundup with no soft topper
- Only pad here that lists F2933-21 play-yard compliance
- Waterproof machine-washable Jacquard cover
- Carry bag included for travel
- Rounded corners and edge support for a no-gap fit
Cons
- Thinner than the 1.5 and 3 inch options
- Cover takes a delicate machine wash or spot cleaning only
- Costs more than the basic one-inch foam toppers
This is the pad we would put in our own playard, and the reason is not the marketing. It is 1.25 inches of polyurethane foam in a three-layer build, which lands right in the middle of the thickness window where a pad is firm enough for a newborn and low enough not to create climb-out height.
The listed compliance figure matters more than it sounds. Federal Regulation F2933-21 is the play-yard mattress standard, and the manufacturer is the only pad in this roundup that puts it on the technical sheet. Reviewers repeat that they looked for exactly this before buying and could not find it elsewhere.
In use, the Jacquard cover is genuinely quiet. There is no crinkling when your baby turns over, which matters more than most parents expect because a baby who wakes on noise at three months will wake on noise at three years. The cover is waterproof, lock-stitched at the binding, and comes off on a zipper for machine washing.
The carry bag is a small thing that changes the use case. If you are moving between a grandparents’ house, a hotel room and a downstairs nap spot, a pad that lives in a bag is a pad you will actually keep using rather than abandon in a closet.
How firm it feels in practice
Press your palm into the centre and you will feel give, but the surface will not hold a print. Release and it comes back immediately. The edges are the firmer part of the pad, which is what stops a baby from rolling into the mesh wall and getting a hand or cheek caught in it.
At 1.25 inches it is thinner than the OEM pad on some Graco and Baby Trend playards, so check the interior measurement before ordering. A pad that is a quarter inch short on any side can leave exactly the kind of gap the two-finger test is designed to catch.
Who should skip it
If you want a full inch of cushioning for a toddler who is past 12 months, this pad is too thin to deliver it and the softer side of a two-stage pad will serve you better. If your playard interior is smaller than 38 x 26, the fit is wrong and no amount of firmness fixes that.
2. Lilian and Gema Portable Playpen Mattress 1.5 Inch – Best Value
Lilian&Gema Pack and Play Mattress 38″x26″x1.5″ Portable Playpen Mattress
38 x 26 x 1.5 inch
25D CertiPUR-US foam
Meets ASTM F2933-21
3 pounds
Pros
- States both CertiPUR-US and ASTM F2933-21
- Waterproof breathable removable cover
- Rounded edges that close off corner gaps
- Carry handle strap for travel
- Four colour options
Cons
- Arrives vacuum packed and needs 48 hours to expand
- Listed as medium firmness so it is not the firmest here
- Core foam is spot clean only
This is the one to buy when you want a stated certification and a slightly thicker build without stepping up to a dual-stage mattress. The foam is listed as 25D CertiPUR-US certified, and the technical sheet also states ASTM F2933-21 compliance, which puts it in the same documentation tier as our top pick.
Density is the number to read if you care about firmness. A 25D polyether foam is on the firmer side of what is sold as a playard pad, which matches the medium-firmness label in the listing and explains why parents report it feels harder than the one-inch toppers they have used before.
The cover is a removable zippered polyester sleeve that is waterproof and breathable, and it comes off for laundering. That matters in this category more than any other feature after fit, because a playard pad sees spit-up, formula and diaper leaks on a daily basis and the pad is the one thing you cannot swap out mid-day.
Rounded edges are the detail that separates this from a plain rectangle. Squared corners on a 38 x 26 pad are where the gap risk hides, and the rounded profile here matches the curve of the playard wall.
What the 48 hour expansion actually involves
The pad arrives vacuum packed, and it needs up to 48 hours at room temperature to reach full thickness. Unpack it, leave it lying flat, and do not put your baby on it the same afternoon. This is the most common one-star complaint in the reviews, and it is entirely avoidable.
Once it has expanded the surface is flat and tight-topped. Press the centre and the edges, release, and you should see no lasting indent. If you can push a whole fingertip into it, the foam is a softer model than you were expecting.
Who should skip it
If you are shopping for a newborn and want the absolute flattest surface available, the 1.25 inch option above is the safer bet on thickness alone. This one is right for you if washable cover and a named density figure matter more to you than the last quarter inch of firmness.
3. NeoBorn Dual-Sided Foam 1.5 Inch – Best for Two-Stage Use
NeoBorn Pack and Play Mattress, 38 x 26 x 1.5 Inch, Dual-Sided Foam
38 x 26 x 1.5 inch
Firm core plus soft cooling gel side
3.5 pounds
TPU waterproof inner cover
Pros
- Two firmness levels in one 1.5 inch pad
- Soft side uses cooling gel memory foam
- Inner TPU membrane blocks leaks before the foam
- Cover is removable and machine washable
- Tencel and polyester cover blend
Cons
- Needs 24 to 36 hours to fully expand
- Some variants measure smaller than the stated size
- Heavier build than the one and 1.25 inch pads
Two-stage does not mean soft for a newborn. It means the pad flips. The firm side is a high-density support foam meant for the first stage, and the cooling gel memory foam side is the toddler side for after 12 months. Parents who flip it early are the ones who generate the negative reviews, and the listing is explicit about which side is which.
At 1.5 inches total it stays inside the safe thickness range, which is the main reason we like it despite the gel layer. A three-inch dual-stage pad sounds generous and is genuinely a problem in a playard, because the extra inch and a half is climb-out height your baby does not need yet.
The cover is where this pad separates itself. There is a TPU waterproof membrane on the inner cover surface, so a leak stops at the cover rather than reaching the foam. The outer cover unzips and goes in the machine on a low delicate cycle and air dries.
That construction is the honest answer to the question parents on r/NewParents ask about a year of daily naps. Foam cores with only a fabric cover eventually smell; a membrane-backed cover can be wiped down and laundered repeatedly without the foam suffering.
How to check the side before every nap
Firm side up until your baby is past 12 months, then flip. Write it on a card and tape it to the playard rail, because the single most common mistake with a two-stage pad is forgetting which way is up at 6am with a crying baby.
Run the same press test on both sides. The firm side should barely move under your palm, and the gel side should compress slightly and rebound. If the firm side feels plush to you, stop using it until 12 months and re-check the label.
Who should skip it
Skip it if your playard is a mini 38 x 24 model, because this pad is 38 x 26 and will overhang. Skip it if you need the pad in a carry bag for air travel, since there is no bag listed here and the water-resistant cover adds bulk. And skip it if you only need six months of infant use, because a single-stage firm pad does the same job with one fewer decision.
4. Lillibearas Brushed Cotton Mattress 1.5 Inch – Best Cotton Cover
Pack and Play Mattress 38″ x 26″, Premium Cotton Fabric – Hypoallergenic
38 x 26 x 1.5 inch
Medium firm high density foam
12.8 ounces
Meets three CFR standards
Pros
- Hypoallergenic brushed cotton cover that absorbs moisture
- Reversible so one side does not wear out early
- Weighs 12.8 ounces so it folds into any bag
- Meets 16-CFR-1633 1632 and 1241 standards
Cons
- Can take up to 72 hours to fully inflate
- Cover is spot clean only
- Slight arrival smell that dissipates
Cover fabric is the whole story here. Brushed cotton is moisture-absorbent and quiet, so spit-up goes into the fabric rather than sitting on a waterproof membrane, and there is no crinkle when your baby moves. Parents who are sensitive to synthetic covers specifically name this as the reason they chose it.
Underneath is high-density foam listed as medium firm, which is a good description of how it reads in a hand. It is the middle of the roundup, firmer than the one-inch topper and softer than the 1.25 inch polyurethane pad, and it is reversible so you can rotate it every two or three months.
At 12.8 ounces it is by far the lightest pad here, and that changes what you can do with it. It folds into a diaper bag, fits in a small suitcase, and is the easiest option to move between a grandparents’ house and home on short notice.
The compliance list is broader than most pads in this category carry. It states 16-CFR-1633, 16-CFR-1632 and 16-CFR-1241 compliance, covering lead and phthalate content. That is not the play-yard mattress standard, so if that specific figure is your filter, check the product above first.
What medium firm actually feels like day to day
Press the centre with your whole palm for five seconds and lift. You should see a shallow temporary mark that disappears within a second or two. If the dent is still there, the foam is too soft for an infant and you should not use it until 12 months.
For a baby who sleeps on their front, medium firm over a firm core is exactly the compromise most parents settle on, because it is flat enough to breathe through but not so hard that a face-down sleeper loses ear contact with the surface.
Who should skip it
Skip it if you need a washable cover, because this one is spot clean only and a year of daily spit-up will show. Skip it if you want a stated ASTM F2933-21 figure, and skip it if you want an obvious texture or colour choice for a nursery, because the design options are limited.
5. YENING Pack and Play Topper 1 Inch – Best for a Washable Cover
YENING Pack and Play Mattress Topper Baby Pack N Play Mattresses for Playpen and Playard with Washable Cover 38″x26″x1″, 1 Pack Firm Foam
38 x 26 x 1 inch
CertiPUR-US certified foam
Waterproof machine-washable cover
1000 g
Pros
- Largest review volume of any one-inch option
- Waterproof and machine washable cover
- CertiPUR-US foam free of PBDEs TDCPP and TCEP
- Breatheable design
- Lightweight enough to move between rooms
Cons
- Only 1 inch thick so the least cushion here
- Will not fit non-standard or mini playard sizes
- Cover options vary between variants
At one inch this is the thinnest pad in the roundup, and for a newborn that is a feature rather than a flaw. Thin and flat is exactly the direction safe sleep guidance points, and several parents on r/BabyBumps report using a thinner pad for months with no discomfort at all.
The cover is the reason to choose it. It is waterproof and machine washable, which means the single most-used part of a playard sleep setup can go into the laundry on a weekly cycle instead of being spot cleaned for a year.
The foam is CertiPUR-US certified and listed as free of PBDE, TDCPP and TCEP flame retardants. If you have ever worried about what is inside a foam pad, that is the line to look for on the packaging, and it is stated plainly here.
With 1650 reviews at 4.6 stars this is one of the two most reviewed products in the roundup, which matters in a category where several listings show only one to three ratings. A large review pool is the closest thing to independent testing you can get in this category.
Whether one inch is too thin for comfort
For a baby under 12 months, no. For a toddler who has learned to roll and kick, you may feel it, because there is almost no give at all. The honest test is the indent check: press and release, and confirm the surface snaps straight back.
If you want a similar washable cover with more substance, the 1.5 inch option above adds half an inch and still has a machine washable cover. The trade is thickness, and for infants you should read that as a choice rather than a compromise.
Who should skip it
Skip it if your playard is a 38 x 24 mini model, because a 38 x 26 pad will sit proud of the rail. Skip it if you are replacing a pad for a toddler who sleeps hot, because one inch of foam with a polyester cover holds more warmth than a thicker or more breathable build.
6. OSSERTSbearY Premium Knitted Pad 1.5 Inch – Best Quiet Pad
Pack and Play Mattress – 38″ x 26″- Premium Knitted Fabric Safety Reinforced Play Yard Mattress – Fits for Graco & Baby Trend & Pamo Babe Playard, Firm Support and Comfort Foam，White
38 x 26 x 1.5 inch
Firm foam core with non-slip base
4 pounds
Meets 16 CFR 1241
Pros
- Firm foam core that resists edge sagging
- Reinforced stitching along the seams
- Non-slip base keeps the pad from shifting
- Knitted cotton blend cover is quiet and breathable
- No chemical odour straight out of the package
Cons
- Needs a few days to fully expand
- Can arrive with a slight bump in the middle
- Firmness is listed as medium rather than firm
Two details set this pad apart from the other foam options. The non-slip base keeps the pad from migrating inside the playard, and the reinforced stitching runs along the seams that usually fail first. Both matter more than they sound when the pad is being climbed on rather than slept on.
Quiet is the other half. A knitted cotton blend cover does not crinkle, and reviewers repeatedly call out the absence of squeaking and rustling as the difference between a baby who resettles and a baby who wakes fully.
The fit claim is specific rather than generic, because it names Graco, Baby Trend and Pamo Babe playards by brand. That is a narrower promise than a universal size claim and a more useful one, since most playard interiors are 38 x 26 but not all of them are the same shape at the corners.
At 4 pounds it is light enough to move with one hand, which makes it a good pick for a downstairs nap setup or a second playard in another room.
Handling the expansion period
Foam pads ship compressed and need time to reach full thickness. Leave this one lying flat for a few days, ideally in the room it will sleep in, and check the middle of the surface for the slight bump that shows up in early reviews before you set a baby on it.
After it settles, run the two-finger gap test along all four edges and then press the centre. The core is listed as firm, which in practice means a small give and an immediate rebound rather than any lasting indentation.
Who should skip it
Skip it if you want a formal play-yard safety standard figure, because the compliance listed here is 16 CFR 1241 for lead and phthalate content, which is a different thing. Skip it if you need a machine washable cover, and skip it if you plan to use the toddler side, because there is no second side here.
7. Lillibearas Two-Stage Topper 1.5 Inch – Best for Fleece and Cotton Blend
Pack and Play Mattress Topper – 38″ x 26″ x 1.5″, Soft & Firm Premium Foam Pack N Play Mattresses Pad, Odorless Baby Foam Playpen Mattresses,Portable Playard Mattress Topper- Breathable & Comfort
38 x 26 x 1.5 inch
Soft and firm foam
360G alpaca fleece and cotton cover
Odorless
Pros
- Two-stage soft and firm foam in a 1.5 inch build
- 360G fabric blend of alpaca fleece and long-staple cotton
- Rounded corners and edge support close off gaps
- Waterproof layer wipes clean
- No noticeable odour on unpacking
Cons
- Less substantial than buyers expect at 1.5 inches
- Thinner than the perceived size suggests
- Soft side is not for babies under 12 months
This is the warmest pad in the roundup. The cover is a 360G weight fabric blend of alpaca fleece and long-staple cotton, which is noticeably warmer to the touch than the polyester covers on most competitors. If your baby sleeps in a cold room in a T-shirt, that is a feature.
It is also the one to skip if your baby runs hot. Fleece traps heat, and parents who switch to this in summer often switch back. The listing itself describes it as breathable and odorless, which is true of the fabric but not the same as cool.
The construction is labelled soft and firm, two-stage, which again means firm side up until 12 months. Read it the same way you would read the two-stage pad above, because the soft side is not a comfort upgrade for a newborn, it is a stage change.
Rounded corners are listed alongside superior edge support, and that combination is the thing to inspect first when the pad arrives. Gap risk in a playard lives in the corners, not along the straight edges.
How thick it really feels
This is the most common surprise in the reviews: at 1.5 inches the pad feels thinner than buyers expect, and several mention assuming it was closer to two inches from the listing photos. Judge it on the measurement, not the render.
Press the firm side and the surface should not indent. Press the soft side and it should compress and come back. If both sides behave the same way, the two-stage construction is not doing much, which is a reason to return it.
Who should skip it
Skip it in warm weather or with a hot-sleeping baby. Skip it if you need a documented safety standard figure, since no ASTM or CFR compliance is stated. And skip it if you want a machine washable cover, because the layer here is described as waterproof and wipeable rather than washable.
8. DeerFable Dual Sided Memory Foam 3 Inch – Best Thick Build
DeerFable Pack and Play Mattress, Dual Sided Memory Foam 38x26x3 Inch, Blue
38 x 26 x 3 inch
Eight-layer structure
70D firm and 40D soft
3.7 pounds
Pros
- Thickest build here with a genuine mattress feel
- Eight layers including two waterproof membranes
- 70D firm side and 40D soft side are clearly specified
- OEKO-TEX Standard 100 fabric and CPSC standard listed
- Reversible cooling and warm sides
Cons
- 3 inches may be too tall for some playards
- Can take up to 48 hours to fully expand
- Heaviest option at 3.7 pounds
This is the highest rated pad we looked at, and it is also the one we are least comfortable recommending as a first choice for an infant. Three inches of thickness in a playard creates exactly the climb-out height that parents on forums warn about once a baby starts pulling to stand.
What you are buying is a build quality story. The structure is eight layers, including two 0.1mm waterproof membranes, two supportive foam layers, a cooling layer and three warm fabric layers. The 70D side is the newborn side and the 40D memory foam is the toddler side, with the density figures stated plainly.
The reversible face is unusual in this category. One side is described as cooling for spring and summer, the other as warm for autumn and winter, which is a cheap way to solve a seasonal problem that a single cover cannot.
Fabric is OEKO-TEX Standard 100 certified, and the listing also states the mattress meets the U.S. CPSC safety standard. Both are useful marks, though neither is the play-yard mattress standard, so treat them as material quality signals rather than compliance proof.
When three inches is right and when it is not
It is right if your baby is past 12 months, if your playard is deep enough that the top of the pad still sits well below the rail, and if you want one pad that lasts several years. Measure the interior depth as well as the width and length before ordering.
It is not right for a newborn in a standard playard. The extra height is the risk, not the foam, and the 1.25 and 1.5 inch options in this roundup exist precisely because that ceiling matters.
Who should skip it
Skip it for any infant under 12 months in a shallow playard, and skip it if you need a carry bag for air travel, since a three-inch pad with eight layers is not a travel item. Also skip it if you want a carry-bag setup for grandparents, where a lighter pad wins every time.
When You Should Not Replace the Pad That Came With It
Most of the anxiety in this category comes from a misunderstanding: the original playard pad is not too hard, it is correct. Parents on Glow and What to Expect repeat the same consensus, that the pad that came with the playard is enough, and that adding thickness to soften the surface is what creates entrapment risk.
So do not replace a pad that is intact, correctly sized and correctly positioned. The three legitimate reasons to replace are that the pad is damaged or torn, that the playard was inherited or hand-me-down and the pad is missing or unsanitary, or that the pad genuinely does not match the interior of the specific playard model you own.
Also do not add anything on top. A memory foam topper, a quilted pad, a fitted mattress pad or a regular crib mattress inside a playard all change the effective surface without changing the safety case for it. If your baby fusses on the pad, that is a temperature, swaddle and burp problem before it is a mattress problem.
One more case where keeping the original wins: a baby who is climbing out. If your baby pulls to stand and is halfway up the rail, replacing a thin pad with a thicker one makes the problem worse. Move to a full crib instead.
How to Choose a Firm Pack and Play Mattress ?
Measure before you order. Measure the interior length, width and depth of your playard at its widest point, and subtract nothing. Standard playards take a 38 x 26 pad, mini playards take 38 x 24, and a 38 x 26 pad in a 38 x 24 playard sits proud of the rail, which is a fall and gap risk rather than a snug fit.
Run the two-finger gap test. Slide two adult fingers between the mattress edge and the playard wall anywhere around the perimeter. If more than two fingers fit with pressure anywhere, the pad is undersized and no amount of firmness fixes it. Corners are where this fails, so check all four.
Run the press-and-release indent test. Press the centre with your palm, then press each edge, and release. A safe surface will not hold a print of a baby’s weight and will rebound immediately. If a dent remains, the pad is too soft for a baby under 12 months.
Keep thickness at 1 to 1.5 inches for infants. Extra height is climb-out height. Once your baby is past 12 months and pulling to stand, thicker becomes reasonable, and a 2 or 3 inch pad starts to make sense in a deeper playard.
Read the certifications carefully. CertiPUR-US means the foam was tested for content and emissions. Greenguard Gold means the whole product, including the cover, met a chemical emissions standard. GOTS means the fibres themselves are certified organic. JPMA is a juvenile product safety seal. ASTM F2933-21 is the play-yard mattress standard and is the one figure specific to this category.
Read the density, not the adjectives. Foam density is the closest thing to a firmness number on a retail page. A figure in the mid twenties is a firmer foam than a figure in the teens, and words like plush or luxury usually mean the opposite of what you want here.
Plan for expansion time. Every pad in this roundup ships compressed, and expansion takes anywhere from a day to three. Unpack, leave it flat, and run your press test again after it has settled.
Think about what else you will use it for. For a dedicated downstairs nap playard, a 3 inch dual-stage build is worth it. For grandparents’ house, a hotel room and the car, you want the lightest option with a carry bag. Our play tent picks cover a nearby scenario if you are furnishing a small space.
If you are past the pack and play stage and shopping for a real sleep surface, our crib mattress rankings and mattresses in a box guide cover the full-size options.
Frequently Asked Questions
What is the best firm mattress for pack-n-play?
A flat high-density foam pad that fills the playard interior with no gap wider than two adult fingers. The Hiccapop Playard Mattress Pad is our pick: 1.25 inches of firm three-layer polyurethane foam, a stated F2933-21 compliance figure, a waterproof machine-washable cover, and 24277 reviews at 4.7 stars. Anything softer than a firm flat surface is a suffocation and entrapment risk under 12 months.
Is pack n play too hard for baby to sleep on?
No. A hard feel is the intended design, not a fault. A safe playard surface distributes weight across the whole pad instead of letting a baby sink in, which is what prevents a face from sinking into a soft surface. Press the centre and the edges with your palm, then release. If no print remains and the surface rebounds, the firmness is correct. Adding a topper to soften it is what creates risk, not what fixes comfort.
Can you buy a better mattress for a pack n play?
You can, but only if you have a reason beyond comfort. The manufacturer pad is the firmest and safest option when it is intact, correctly sized and correctly positioned. Replace it if it is lost, torn or contaminated, if the playard was inherited and the pad is missing, or if the pad does not match the interior of your specific model. For anything else, keep the original.
What size mattress can fit in a pack n play?
Standard playards take a 38 x 26 inch pad. Mini and portable playards take 38 x 24 inches, and a 38 x 26 pad placed in a 38 x 24 playard sits proud of the rail. Measure the interior length, width and depth of your specific model before ordering, then run the two-finger gap test all the way around the perimeter, corners included.
Should babies sleep on a firm mattress?
Yes. Safe sleep guidance calls for a firm, flat, non-cushioned sleep surface in a safety-approved sleep space. Firmness works by distributing weight across the whole surface instead of allowing contours around a baby’s body and face. That is why extra padding, quilts and memory foam toppers are actively discouraged in playards.
What is a safe mattress for a pack-n-play?
A flat, firm, correctly sized pad with no gap wider than two adult fingers on any side. Check for a stated safety standard such as ASTM F2933-21, foam certifications such as CertiPUR-US or materials certifications such as OEKO-TEX Standard 100, a removable washable or waterproof cover, and edges that meet the wall. Replace the pad if it is torn, sagging or has persistent indentations.
Which pack and play has the thickest mattress?
Thickness in this roundup runs from 1 inch on the YENING topper to 3 inches on the DeerFable dual-sided memory foam build, with most pads landing at 1.5 inches. Thickness is not automatically better. For a baby under 12 months, 1 to 1.5 inches is the right window because extra height becomes climb-out height in a playard.
What pack n play has the most comfortable mattress?
Comfort depends on age, and the answer changes at 12 months. For an infant, the most comfortable surface is a firm flat one, because softness is a hazard rather than a comfort. For a toddler past 12 months who is rolling and kicking, the softer side of a dual-stage mattress is genuinely more comfortable, and pads with 1.5 inches or more of foam feel more substantial than a one-inch topper.
The Firmness Pick We Would Make in 2026
If your original pad is intact, keep it. That is the default answer for most people searching for the best pack and play mattresses for firmness, and it is the one the safety guidance supports.
When you do need a replacement, the Hiccapop Playard Mattress Pad is our pick: firm three-layer foam at 1.25 inches, a stated play-yard standard compliance figure, a waterproof washable cover, a carry bag, and 24k reviews at 4.7 stars. The Lilian and Gema 1.5 inch pad is the better value if you want a named foam density and a colour choice, and the NeoBorn dual-sided pad is the one to buy if you want one surface to cover the newborn stage and the toddler stage.
Whatever you order, measure the interior first, run the two-finger gap test all the way around, and press the centre before the first nap. Those three checks take two minutes and answer the firmness question better than any adjective on a listing.
