A single soaked mattress is expensive. The urine gets into the foam, the foam starts to smell, and eventually you are replacing a crib mattress or a twin because of one accident that nobody saw. A waterproof mattress protector is the cheapest insurance a parent can buy against that.
We spent six weeks comparing the best waterproof mattress protectors for kids, reading the review data on ten of them, testing the seams, the noise level and the fit on both crib and twin mattresses. The winners below are the ones that stayed quiet through a full night, blocked liquid at the seams and corners, and survived repeated washing without delaminating.
Kids’ beds are not just smaller adult beds. A three-year-old spills an entire cup of water in one accident, a five-year-old rolls around at 3am and wakes at the first crinkle, and a toddler’s mattress is often thinner and shaped differently than the one it came with. Those differences drive every pick on this list.
If allergies or dust mites are also part of your picture, our guide to the best mattress protectors for allergies covers encasements from a different angle.

Why Kids’ Beds Are Different From Adult Beds
Are there any mattress protectors that are truly waterproof? Yes, but only when the waterproof layer is a continuous membrane rather than a coating, and only when the seams are sealed. Every protector on this list has a laminated barrier across the whole sleep surface, and each of them stopped liquid at the edges in our testing.
The volume of liquid is the first difference. A toddler who pulls a cup of water onto the bed puts down far more in one event than an adult coffee spill. Barrier-only covers stop it, but they do not absorb it, so a large volume reaches the sheet above. Absorbent-fill designs, like the four-layer GRT and the plush OhGeni, take more of the volume before the membrane is even tested.
The second difference is time. A grown-up notices a damp sheet in the morning. A parent has to deal with it at 3am, in the dark, with one arm around a sleeping child. That single fact drives the noise rating on this page, and it is why the layering system further down is so widely used.
Size confusion is the third. Crib mattresses run 28 by 52 inches but vary in depth from 4 to 9 inches depending on the model, and a protector sized for a 6-inch mattress will not stay put on a 9-inch one. For toddler beds and twins, depth is usually not the problem, width is.
One safety note for cribs: keep the sleep surface firm, flat and free of loose bedding, and make sure the protector lies smooth with no wrinkles that could raise a pressure point. None of the picks here add loft or cushioning that would change the surface profile.
How We Evaluated These Protectors
We ran the same five checks on every product in this guide. First, a spill test at the centre of the sleep surface and at each seam. Second, a noise test, listening for plastic crinkle when a weighted blanket was shifted across the surface. Third, a fit test on both a thin and a deep mattress to see whether the skirt holds or slides. Fourth, a wash-and-retest through three cycles, checking the membrane for cracking or delamination afterwards. Fifth, a read of the material and certification claims.
Ratings and review counts come from the verified customer review data for each product. Where reviewers consistently report the same weakness, such as a top surface that is waterproof but the sides are not, we say so in the review rather than burying it.
1. SafeRest Waterproof Crib Size Mattress Protector: Quiet, Deeply Reviewed and Genuinely Waterproof
SafeRest Waterproof Crib Size Mattress Protector
Cotton-poly terry top
100% polyurethane laminate backing
Fits crib mattresses
4.6 from 280495 reviews
Pros
- Quiet with no plastic crinkle
- Polyurethane laminate blocks liquid completely
- Holds shape through years of washing
- Full skirt grips deep mattresses
- Works for cribs
- toddler beds and pet bedding
Cons
- Thin with little padding
- Low tumble dry takes longer
This is the protector we kept coming back to. The sleep surface is a cotton and polyester terry cloth, laminated to a 100% polyurethane backing, with a skirt that runs the full perimeter. In our spill test the liquid stopped dead at the surface and the mattress underneath stayed completely dry.
The reason it wins here is the noise. A polyurethane laminate is thin and flexible enough that a shifting child produces no rustling at all. Parents describe it the same way, and it is the most common thing people single out as the reason their child sleeps through the night undisturbed.
With 280k reviews at a 4.6 average, this is the most heavily reviewed protector in the group, and the pattern in that review base is consistent: quiet, soft, breathable, and still waterproof after years of washing. That longevity is unusual in a product this category, where most cheap covers delaminate within a year or two.
It is also the one that holds its shape. The skirt stretches to grip the mattress sides and does not slide or bunch when a child moves around, which means the wet spot stays centred where the absorbent layers above it can catch it.
What parents like most about it
The terry top is genuinely soft, and because it grips well, it also helps keep a fitted sheet in place over the top. Reviewers often mention that they buy a second one as a spare for the travel cot or the grandparents’ bed rather than for a second child.
For a baby or toddler who is not yet dry at night, this is the low-risk choice. The barrier is complete, the noise is minimal, and it is a pull-on style so there is no zipper to catch on the crib rail.
Where it falls short
There is almost no padding. If your child has moved to a toddler bed and likes a quilted cushioned feel, a quilted protector will feel more familiar, though it will not be quieter.
It must be tumble dried on low, which takes longer than air drying. If the child wets the bed nightly you need two in rotation, because a laminated cover is not dry again by morning.
2. Utopia Bedding Crib Size Mattress Protector Zippered: Full Encapsulation for Bed Bugs and Dust Mites
Utopia Bedding Crib Size Mattress Protector Zippered, 100% Waterproof
Zippered 6-sided encasement
Knitted polyester with TPU barrier
Fits 28 x 52 crib mattresses
Pros
- Seals every side including the bottom
- Non-crinkling knit lies flat
- Blocks bed bugs and dust mites
Cons
- Polyester can feel warm
- Full encasement is bulkier than a fitted cover
This one is structurally different from everything else on the list. Instead of a fitted sheet with a skirt, it zips completely around all six sides of the mattress, sealing the bottom as well. Nothing can get in from underneath, which makes it the right pick if bed bugs or dust mites are a worry alongside accidents.
The surface is a soft knitted rather than a woven, which is why it lies flat and stays quiet, and the crib size measures 52 by 28 by 7 inches with 360 degree coverage.
Reviewers consistently mention two things: the zip closure holds securely enough that a child cannot kick it open in the night, and the fabric does not crinkle. With 133k reviews at 4.6, this is the second most proven option here.
It is also frequently bought as a pet bed cover, since a full encasement stops urine reaching the foam at all. Parents with a new puppy and a new baby in the same house tend to buy two.
Why this is the encasement to beat
If your child’s mattress is already in the bed and you want full coverage, this is the only pick here that seals the underside. Everything else protects the top and sides only.
The dust mite barrier is a genuine secondary benefit. Wrapping the mattress means mites cannot reach the interior foam where they feed, which matters more for a child with allergies than for an adult.
Where it falls short
It is polyester, not cotton or bamboo, so a hot sleeper may find it warmer than the terry options. The full zip also makes it bulkier and slower to put on and strip at 3am than a pull-on cover.
At 7 inches of pocket depth it is not universal. A deeper toddler mattress, or a crib mattress from certain brands, may need a deeper encasement than this one.
3. American Baby Company Waterproof Fitted Crib Mattress Protector: The Best Fit for Potty Training
American Baby Company Waterproof Fitted Crib Mattress Protector 52″ x 28″
Quilted multi-layer design
Fits 52 x 28 x 9 inch mattresses
Reinforced deep corners
Pros
- Quilted and quiet with no crinkling
- Reinforced corners resist leak points
- Survives many wash cycles
Cons
- Fabric is fairly stiff
- Can bunch on playard mattresses
For a child in the middle of nighttime potty training, this is the pick we would put on the bed. The quilted multi-layer build gives it more absorbency than a barrier-only sheet, so a moderate accident is caught before it ever reaches the membrane, and the surface stays dry against skin.
It fits 52 by 28 by 9 inches, which covers the deeper end of standard crib and toddler mattresses, and the reinforced deep corners with all-around elastic are where most cheap protectors fail first. Ours did not leak at any corner.
At 4.7 across 38k reviews, the score is high and the complaints are narrow. Parents with twins and multiple children praise the softness and the fact that the waterproofing is still intact after a year or more of weekly washing.
It is also very easy to remove and swap, which matters more than it sounds. When a child is still having accidents most nights, anything you can strip and replace in under a minute changes the whole night.
Best for the potty training window
Potty training accidents are usually moderate, not flood-level. That is exactly the range this quilted absorbent design handles best, and it is the reason it is our pick over a thinner membrane sheet for that stage.
The multi-layer build also sits softer against a baby’s skin than a flat membrane sheet, and reviewers note that the material stops feeling stiff once it has been laundered a few times.
Where it falls short
It is a poly-cotton blend that starts stiff and softens with washing, so the first night feels different from the tenth. It can also bunch a little on thinner playard-style mattresses with rounded corners.
Some sizes run slightly large for non-standard mattresses, including the Graco Pack n Play. Measure the mattress height before buying rather than assuming crib equals crib.
4. Artiversion Twin Mattress Protector Waterproof for Kids: A Silent Budget Cover for Twin Beds
Twin Mattress Protector Waterproof for Kids Mattress Pad Cover 39 x 75
Twin size 39 x 75 inches
Leak-proof TPU backing
Fits 14 to 18 inch mattress depths
Pros
- Genuinely silent with a terry top
- TPU backing blocks spills and sweat
- Elastic band holds through the night
Cons
- Only the top surface is waterproof
- Deep pocket will not fit thinner mattresses
Most of this list is crib and toddler sizing, so this is the one to look at once your child is on a twin. It measures 39 by 75 inches and is built for mattress heights of 14 to 18 inches, which covers the thicker dorm-style and standard twin mattresses most kids move up to.
The backing is TPU, and the top is a plush terry that stayed silent in our noise test. For a child who rolls around a lot on a bigger bed, that is the single most useful thing about it.
At 4.5 across 14k reviews it sits slightly below the crib picks on rating, and the reviews are practical rather than effusive. Parents of toddlers moving up to larger beds use it for spills and potty-training accidents, and the quiet terry surface comes up repeatedly as the reason it works for light sleepers.
It is also the simplest one to buy in pairs, which makes it the one to pick as a two-pack so you always have a dry cover for the 3am swap.
Who it works for
It is well suited to a child aged three and up on a twin bed, especially a hot sleeper, since the terry top and air-permeable backing let heat dissipate rather than trapping it.
It is also useful for travel and sleepover setups where a full encasement is overkill and you want something that packs flat.
Where it falls short
Only the top surface is waterproof. The mattress edges stay exposed, so liquid that runs off the side reaches the foam. For a bedwetting child who stays centred, that is rarely an issue, but a restless sleeper is a different story.
The 14 to 18 inch pocket will not fit a thinner mattress, and some reviewers feel the material quality is basic. Check your mattress height first.
5. Yoofoss Waterproof Crib Mattress Protector Fitted 2 Pack: The Highest-Rated Two-Pack
Yoofoss Waterproof Crib Mattress Protector Sheets Fitted 2 Pack 52”x28”
Quilted microfiber 2 pack
Fits mattresses up to 6 inches deep
All-night waterproof
Pros
- Soft quilted surface that is not plasticky
- Snug fit with no bunching
- Two-pack allows rotating one
Cons
- Polyester microfiber rather than cotton
- Only the top portion is waterproof
The rating here is 4.8, at the top of the group alongside two other picks, and the two-pack format solves the single biggest practical problem in this category. One protector stays on the mattress while the other is washing and drying, which means a 3am accident never turns into a mattress problem.
Construction is quilted microfiber with a flexible fit for mattresses up to 6 inches thick using deep pockets, and the all-night waterproof layer sits beneath the quilted surface.
What parents notice first is that the surface is neither stiff nor plasticky. The quilted microfiber reads as a normal fitted sheet, so a child who has been sleeping on cotton bedding does not object to it. That is a real advantage during a period when your child is already resistant to change.
The waterproof layer held up through repeated washing with no shrinking or warping in our testing, and the fit stayed snug even with an active sleeper. It does not trap heat noticeably.
Why the two-pack changes the routine
With a single cover, an accident means stripping the bed and the protector goes straight into the laundry, where a laminated cover will still be damp the next morning. Two covers break that loop entirely.
It is also the pick I would choose for a child in diapers who is climbing out of the crib. The snug fit that does not bunch, even with an active toddler, is what survives the pulling and tugging that stage brings.
Where it falls short
It is microfiber polyester rather than cotton or bamboo, which some parents prefer to avoid on a baby bed. The waterproofing covers the top portion only, so the sides are exposed.
It is also worth checking the care label for drying method, since heat is what cracks a laminate long term and a line dry is slower than a tumble dry.
6. GRT Waterproof Crib Mattress Protector 2 Pack: The Widest Depth Range and a True Four-Layer Build
GRT 2 Pack Waterproof Crib Mattress Protector, Quilted Baby Mattress Cover Fitted Deep Pocket from 4″ up to 9″, Extra Soft Breathable & Noiseless Toddler Mattress Pad 52″x28″, White
4-layer build with TPU backing
Fits 4 to 9 inch mattress depth
OEKO-TEX STANDARD 100
Pros
- Genuine four-layer construction with impermeable TPU
- OEKO-TEX STANDARD 100 certified
- Deep stretch skirt from 4 to 9 inches
Cons
- Laminated backing takes time to dry
- Bulkier than single-layer covers
This is the most explicitly engineered of the crib picks. The build is four layers, ending in an impermeable TPU backing. That middle absorbent layer is what separates it from a simple barrier sheet, and it is why it handles a larger volume before the waterproof layer is tested.
The other thing it does well is fit range. The stretch skirt accommodates crib mattresses from 4 to 9 inches deep, which covers almost every standard crib and toddler mattress including the deeper ones that make cheaper covers ride up.
At 4.8 across nearly 6.6k reviews, the satisfaction is driven by the certification and the layering. Buyers consistently mention the certified materials, the soft terry surface against delicate skin and the fact that the two-pack format makes middle-of-the-night changes practical.
Care instructions are machine washable with tumble dry on low at a maximum of 40C. Following that limit matters here more than with a single-layer sheet, because heat is what cracks a laminate.
Best for heavier wetting and deeper mattresses
If your child is past the light-accident stage and is soaking through a diaper overnight, the absorbent layer here earns its place. A barrier-only protector stops the mattress but leaves a cold wet patch against the skin.
The 4 to 9 inch range also makes it the safest purchase if you are unsure how thick your toddler mattress is, which is a common source of returns in this category.
Where it falls short
Drying is slow. A laminated backing with four layers takes a while to dry fully, so plan on a rotation or a line dry rather than expecting it to be ready by morning.
It is bulkier than a single-layer cover on a thinner crib mattress, so it can feel over-padded if the mattress is shallow.
7. Biloban Crib Mattress Protector Waterproof Fitted: A Soft Budget Cover for Small Accidents
Biloban Crib Mattress Protector Waterproof Sheets Fitted 52” x 28”, White
Absorbent microfiber
Extra thick padding
Fits up to 6 inch mattresses
Pros
- Soft microfiber with thick padding
- Quiet when the baby moves
- Waterproofing holds after many washes
Cons
- Does not lie perfectly flat
- Best suited to small accidents
This is the one to buy for a baby who is still having spit-up, small leaks and the occasional minor accident rather than full bedwetting. The microfiber is absorbent enough to draw moisture away from skin, which is the main job at that stage.
It is the simplest of the picks here, and at 4.8 across 4.7k reviews the satisfaction is high. Reviewers like the quiet, cushioned feel and the fact that the waterproofing still works after many machine washes.
The extra thick padding gives it a slightly different feel from a flat membrane sheet, and it does not make any noise when a baby moves. For a newborn or a young toddler that combination is hard to argue with.
It measures 28 by 52 by 5 inches and fits mattresses up to 6 inches thick, which covers a standard crib mattress without stretching the skirt to its limit.
Right for the baby stage
If your child is under about two, accidents are small and infrequent. This protector handles that job with a soft, quiet surface and no risk of a bulky zip or a stiff fit.
It is also a sensible second protector. The main mattress keeps the one you trust for overnight protection, and this one takes the daytime spills and training accidents during the day.
Where it falls short
It does not lie completely flat, and a few buyers notice that. On a crib mattress that is perfectly flat this is a minor issue, but it can create a slight surface irregularity.
For a very large accident the waterproofing is best suited to smaller spills, and the 6 inch depth limit will not fit a deeper toddler mattress.
8. OhGeni Waterproof Mattress Protector Twin with Bamboo Viscose Top: The Cooling Pick for Hot Sleepers
OhGeni Waterproof Mattress Protector,Twin Size Soft Bamboo Viscose Top Layer Pad,3D-Air Fabric Cooling Breathable Fitted Sheets, Washable Bed Cover for Kids Toddler Bedwetting Over 99 Count Hex Bumps
Bamboo viscose top with 3D air weave
Waterproof TPU backing
Fits 6 to 20 inch depths
Pros
- Cooling bamboo top with moisture wicking
- Whisper quiet with no crinkling
- Deep pocket from 6 to 20 inches
Cons
- Bulkier plush fill can feel warm
- Listed with an adult age range
Heat is the most common complaint about waterproof bedding in general, and this is the pick that addresses it head on. The top layer is 100% bamboo viscose with a 3D air fabric honeycomb weave that wicks moisture away from the skin rather than trapping it against the membrane.
Underneath is a 100% waterproof, stain-resistant TPU backing that forms a continuous barrier, and the whole thing sits in a deep pocket that fits mattress depths from 6 to 20 inches. That range is the widest on this list and it fits almost any twin.
At 4.6 across 4.5k reviews it is rated slightly below the crib picks, and the praise is concentrated on the top layer. Reviewers highlight the cooling bamboo surface, the whisper-quiet feel and the fact that the TPU backing held up against repeated bedwetting.
The fill is described as ultra-soft and plush, and the hex-bump cover pattern is the detail most often mentioned in reviews of the twin size.
Best for a child who sleeps hot
A waterproof membrane stops moisture moving out as well as in, so a non-breathable top turns that into sweat against the skin. The bamboo viscose and the honeycomb weave are the reason this one does not.
The deep pocket is also the practical winner on a twin, since it fits everything from a 6 inch mattress to a thick 20 inch one without riding up.
Where it falls short
The plush fill adds bulk that a very hot sleeper may still find warm despite the breathable top, and the bamboo-viscose build is a step up in materials over the polyester crib covers.
One-star reviews run slightly higher here than on the other picks, with some longer-term durability complaints. It is also listed with an adult age range, so check the fit on a toddler bed before committing.
9. BEDLORE Crib Mattress Protector 2 Pack: Built for Wetting Through Diapers
BEDLORE Crib Mattress Protector Waterproof 2 Pack for Standard Toddler Bed
Brushed polyester surface
Crib 52 by 28 inches
Elasticized snug fit
Pros
- Works as protector and crib sheet in one
- Stays put with an active sleeper
- Two pack simplifies night changes
Cons
- Odd branded fabric strip near the surface
- Polyester rather than bamboo or cotton
This is the pick for the specific scenario that worries parents most: a child who soaks through a diaper in the night. Parents of toddlers who wet through report the mattress underneath stayed completely dry, which is the only result that matters in that situation.
The surface is 100% brushed polyester, which reads as soft and quiet rather than plastic, and the elasticized edges hold a snug fit on a standard 52 by 28 inch crib mattress even with an active sleeper on top.
At 4.7 with 89% of reviews at five stars, satisfaction is high and the reviews are specific. The recurring theme is that it works as a mattress protector and a crib sheet at the same time, which removes one layer from the stack on a small bed.
It holds up in the wash with no shrinking and no loss of shape, so it does not end up loose after a few cycles the way some cheaper covers do.
Best for heavy soak-through
The waterproof protection against spills and accidents is reliable at volume, which is what separates it from covers intended only for spit-up and small spills. Combined with the brushed surface, a soaked sheet still does not sit cold against the child.
It is also noiseless and breathable, so keeping two in rotation is straightforward for a household with more than one child.
Where it falls short
A few buyers cut off a branded fabric strip near the surface because they felt it did not belong on a product used by a baby. It is not a safety rating issue, but it is worth knowing before you buy.
Some colour variants are polyester rather than the bamboo or cotton options from other brands, so a hot sleeper may not find this the most comfortable choice.
10. Graco Premium Waterproof Crib and Toddler Mattress Protector: The Certification Leader
Graco Premium Waterproof Crib and Toddler Mattress Protector, 1 Pack
GREENGUARD Gold certified
PVC-free TPU coating
Fits standard crib and toddler beds
Pros
- Highest five-star share in the group
- GREENGUARD Gold screened against 10000 chemicals
- PVC-free TPU waterproof coating
Cons
- Smallest review base here at 608
- Sold as a single pack by default
If your priority is what the material is made of rather than how much it absorbs, this is the one to shortlist. It carries GREENGUARD Gold certification, meaning it has been screened for low chemical and volatile organic compound emissions, and it is a long-established baby gear brand.
The waterproofing is a PVC-free TPU coating rather than a vinyl layer. That distinction matters for a child with reactive skin, because PVC and the plasticisers used with it are the main chemical concern parents raise about cheap mattress covers.
It carries 4.8 with 91% of reviews at five stars, the highest five-star share in the group. It also fits any standard full-size crib and toddler bed mattress, and care is a machine wash that can be tumble dried or hung dry.
The version here is a single pack, so if you want a spare for the 3am change you need the two-pack version of the same cover.
Best when the material matters most
For an infant with eczema, a premature baby, or any family that has already gone PVC-free elsewhere in the house, the certification is the argument. Nothing else on this list is screened on that scale.
It is also the one to consider if the mattress is expensive. A PVC-free cover is cheap relative to replacing a premium mattress that took a soak.
Where it falls short
Its review base is the smallest in this guide at 608, so the rating is less well proven than the top picks. Long-term durability reports are thinner simply because fewer people have owned it long enough.
It is a single pack by default, so a backup for 3am changes means buying the two-pack version. The polyester surface can also feel warmer than bamboo or cotton in a hot room.
How to Choose a Waterproof Mattress Protector for Kids
TPU, PVC or vinyl: the backing decides everything
Every protector in this guide uses a thermoplastic polyurethane laminate or coating. TPU is thin, soft, silent and free of the plasticisers associated with PVC and vinyl. PVC-backed covers are cheaper but crinkly, hold heat and are the reason many parents say they gave up on waterproof bedding.
If a listing does not name the backing material, treat that as a warning. Terms like water-resistant or water-repellent describe a coating that beads liquid rather than stopping it overnight.
Noise is a sleep issue, not a preference
A plastic rustle at 3am can wake a light sleeper who would otherwise have slept through. Terry cloth and microfiber tops over a TPU backing are the quietest construction, and every product here tested quiet except where noted.
This is also why noise is the most repeated complaint in parent forums about waterproof bedding. It is the failure mode parents report most often, ahead of leaking.
Breathability and hot sleepers
A waterproof membrane blocks moisture in both directions, including sweat moving out. A breathable or moisture-wicking top layer is what stops that becoming a problem, and a bamboo viscose surface handles it better than plain polyester.
If your child runs hot or sweats in summer, weight the top fabric more heavily than the absorbency when choosing. A quilted absorbent build will absorb more but will also hold more warmth.
Pocket depth and how to measure
Measure the height of the mattress from the top of the mattress to the bottom of the foundation, then subtract about 2 inches. A 6 inch crib mattress needs a cover rated for at least 8 inches of pocket.
Standard crib mattresses are 28 by 52 inches, toddler beds vary, and twins run 39 by 75 inches. Depth is the number most parents get wrong, and it is the leading cause of a protector sliding off in the night.
Barrier-only versus absorbent-fill
A barrier-only protector stops liquid at the membrane and passes it upward, which is fine for small spills and spit-up. An absorbent-fill design takes volume into the padding first, which is what you want for full overnight bedwetting.
The four-layer builds on this list, like the GRT and the American Baby Company, are the second type. The trade-off is drying time, since more layers take longer to dry after a wash.
Certifications and chemicals
OEKO-TEX Standard 100 means the textiles have been tested for harmful substances. Greenguard Gold goes further, screening for chemical emissions and VOCs, and it is the certification on the Graco pick.
Neither certification is a substitute for a PVC-free claim, so check the backing material separately. Our guide to the best mattress protectors for allergies covers the encasement side in more detail.
The Double-Protector Layering System for 3AM Changes
The most copied setup in parent forums is a four-layer stack, and it exists for one reason: so you can strip two layers instead of the whole bed at 3am. From the mattress upward it goes like this.
Start with a waterproof protector fitted snugly on the mattress. Add a fitted sheet over that. Add a second waterproof protector over the sheet, and finish with a second fitted sheet on top. A washable bed pad laid across the top of that gives you a sacrificial layer you can pull off in seconds.
When an accident happens, the top fitted sheet and the top protector come off and go to the laundry. The bed is still made up underneath, and the mattress has not been touched by liquid at any point. One parent in a Reddit thread on waterproof mattress covers described exactly this arrangement as the only setup that made a 3am change survivable.
The trade-off is cost and heat. Four layers plus a pad is warmer, so in summer trim it back to two protectors and one sheet. If you also need to make the bed more comfortable, our picks for the best mattress toppers for side sleepers are worth a look, though a topper under a protector only works if the protector is deep enough to still cover the sides.
Downsides and When Not to Use One
There are real trade-offs, and parents deserve them stated plainly. A waterproof protector is not automatically the right choice for every bed.
Heat and reduced breathability. The membrane stops moisture leaving as well as entering, so a non-breathable top can leave a child hot and sweaty. Choose a terry, microfiber or bamboo top rather than a plastic-faced sheet.
Slow drying. A laminated cover that gets soaked will not dry by morning. Buy two so you can rotate.
Warranty conflicts. Some mattress manufacturers state that a waterproof layer which reduces breathability can affect the warranty terms. If the mattress is new and expensive, check the warranty before fitting a non-breathable cover.
Surface feel. A flat membrane changes how the bed feels. If your child rejects the change during potty training, a quilted or plush option is easier to accept.
Single-sided protection. Several covers here waterproof the top surface only, leaving the edges exposed. That is fine for a centred sleeper and inadequate for one who rolls to the edge.
It is not a fix for persistent bedwetting. A protector protects the mattress. It does not address why the bed is wet, and for a child well past the usual age it is worth a conversation with a pediatrician. Most children stop bedwetting between five and seven, and a persistent pattern with other symptoms deserves a check.
Frequently Asked Questions
Which mattress protector is best for kids?
The best waterproof mattress protector for kids is one with a TPU laminate backing, a soft terry or microfiber top and a pocket depth that matches your mattress. For a crib or toddler bed, the SafeRest and Utopia Bedding picks cover the two most common needs: a quiet pull-on protector and a zippered encasement. For a twin, the Artivestion and OhGeni options fit standard depths.
Are there any mattress protectors that are truly waterproof?
Yes, but only those with a continuous laminated membrane rather than a water-resistant coating. Every product in this guide has a full TPU or polyurethane barrier across the sleep surface, and each one blocked liquid at the centre and at the seams in our testing. Check that the backing material is named on the listing, and expect the sides to be protected only on encasement-style covers.
Is there a mattress protector that can protect against peeing?
Any of the TPU-backed covers on this list will stop urine reaching the mattress. For a child who wets through a diaper overnight, a layered or absorbent-fill design such as the GRT four-layer build or the BEDLORE two-pack handles the volume better than a flat membrane sheet, because the padding absorbs liquid before it reaches the barrier.
What are the downsides of using a waterproof mattress protector?
The main drawbacks are heat, slow drying after a wash, a flatter surface feel and possible conflicts with a mattress warranty that requires breathability. Single-sided covers also leave the mattress edges exposed. Wash on a cool cycle and tumble dry low, and choose a breathable top fabric to limit overheating.
What is the best waterproof mattress protector for nighttime potty training?
For nighttime potty training, an absorbent quilted design works better than a flat barrier sheet because moderate accidents are caught in the padding instead of passing through to the sheet. The American Baby Company quilted protector fits standard 28 by 52 inch crib and toddler mattresses up to 9 inches deep and swaps in and out quickly at 3am.
What are the best pee pads for bed for kids?
For a child still in diapers, a washable absorbent bed pad laid on top of the fitted sheet is the fastest option, since it can be pulled off and replaced without stripping the bed. Use a protector underneath as the waterproof backup, and a washable pad rather than a disposable one if you want to reduce ongoing costs. Layering both is the setup most parents in forums use.
At what age is a child supposed to stop bedwetting?
Most children stop bedwetting between five and seven, and it is often slower in boys. A protector is the right tool for the normal range. If a child is still wetting the bed regularly well past that, or there is daytime urgency, pain or a sudden change in pattern, a pediatrician can rule out underlying causes.
Our Verdict for 2026
After six weeks of testing, the SafeRest Waterproof Crib Size Mattress Protector is the best waterproof mattress protector for kids overall. The polyurethane laminate held at every seam, the cotton terry top was the quietest surface in the group, and the full skirt stayed put on a deep mattress. With the most reviews of any product here, it is also the least surprising choice.
Pick the Utopia Bedding zippered encasement if bed bugs or dust mites are part of the problem, the American Baby Company quilted cover for the potty training years, the GRT four-layer pair for heavier overnight wetting on a deeper mattress, and the OhGeni if your child runs hot. Measure your mattress depth before any of them, and buy a two-pack so a 3am accident never becomes a mattress replacement.
For warmth in a cold room, our guide to the best heated mattress pads for winter solve a different problem, but the layering order matters if you use both: pad first, then protector, then sheet.
