The main reason to get a mattress protector is to keep one of the most expensive items in your bed clean, dry, and stain-free. A good one will create a waterproof, and sometimes hypoallergenic, barrier that’ll prevent any errant liquids from damaging the foam and innards of your mattress, as well as keeping it free of discoloration.
But the value of preventing those weird yellow patches isn’t just cosmetic. It’s the key to ensuring your mattress warranty remains intact. Almost all mattress brands will have a clause about staining and discoloration in their warranty fine print, using those physical markers as a proxy for liquid damage. Using a mattress protector will give you the best chance of making a successful warranty claim if anything goes wrong in the five to ten years that you might spend sleeping on it.
As a sleep writer who believes strongly in the importance of protecting your mattress, I wanted to find the best mattress protectors that will keep your mattress clean without making too much noise or causing you to overheat while you sleep. I combed through all the recommendations the Strategist has ever received from experts who specialize in bed bug removal, pest control, potty training, and sleep. I also surveyed my colleagues — several of whom have kids and pets — to find out which mattress protectors they swear by. And finally, I tested a few mattress protectors myself, including by pouring a cup of water directly onto them, to share my notes on how well they work and what they feel like to actually sleep on.
If you or someone in your household is navigating potty training, bed-wetting, incontinence, or a bedbug issue and you’re looking for a specific type of mattress protector, use the table of contents to jump ahead, or keep reading to learn what you should consider as you shop. And once you’ve checked a mattress protector off your list, we also have guides to the best pillows, mattress toppers, and sheets.

What we’re looking for
Fabric
Mattress protectors are generally made from cotton, polyester, bamboo, or a blend of multiple fabrics over a waterproof layer of polyurethane or vinyl. However, the experts we spoke to when reporting specifically on anti-bedbug mattress protectors suggested avoiding vinyl. “Vinyl covers aren’t breathable and rip very easily because they have no stretch,” says Matthew Moers, co-owner of EZ Pest Exterminating. Potty-training consultant Renee Meyer also suggests avoiding vinyl because it is not very comfortable to sleep on and can disrupt rest. Beyond that, the material you choose is mostly a personal preference. Polyester is stretchy and durable but can be noisy. To avoid any unpleasant swishing sounds, look for a protector with a softer comfort layer, such as a thin padding of cotton, over waterproof materials like polyurethane. Cotton is also quieter and a little more breathable than polyester, though it’s slightly less durable. Bamboo blends are better for hot sleepers or those looking for more sustainably sourced materials.
Protective qualities
Your mattress protector can serve more than one purpose. You might need a waterproof protector to keep a child’s mattress dry while potty training, a hypoallergenic protector if you are sensitive to dust mites, or a bedbug-resistant protector that will fully encase your mattress instead of covering just the top of it. Some protectors can check off all those boxes, while others focus on one function more than others.
Mattress fit
You want a protector that will fit your mattress tightly. A loose fit provides more opportunities for bugs, mites, and liquid to penetrate through to your mattress and it can make the protector noisier when you move around at night. If you’re looking for a cover that will protect your bed from bugs, Jeffery White, owner and CEO of White Mantis Consultants, says that choosing one with a quality and secure zipper closure is also essential. “If the teeth are too large, the bugs may be able to get through the zipper even when closed. Also, where the zipper end-stop is located, there should be some sort of design aspect that makes sure there isn’t a gap between where the zipper closes and the fabric itself,” White explains. Kay McDonald, trainer and handler at Bed Bug Detection K-9s, points out that bedbugs can also take up residence in your box spring, if you have one, so it’s wise to consider purchasing a protector to fully encase that part of your bed as well. The best way to ensure a snug fit is to match the mattress protector with the height of your mattress. Below, we’ve noted the maximum depth that each mattress protector will fit.
Cleaning
By design, mattress protectors collect sweat, moisture, and a laundry list of other stuff that you don’t want on your actual mattress. This means they need to be washed regularly, just like your bedsheets. Most mattress protectors are machine washable, but some aren’t designed to be tumble dried. If you are using a cover as part of a bedbug-management plan, White says that you should leave it on your mattress for at least a year to ensure that the bugs are dead and the problem is resolved.
Best mattress protector overall
Fabric: Cotton terry over polyurethane | Protective qualities: Hypoallergenic and waterproof | Style: Fitted sheet | Pocket depth: 18 inches deep | Care instructions: Machine wash and tumble dry
This mattress protector from SafeRest is our top pick because it’s reliably waterproof, comfortable to sleep on, and pretty affordable. We first learned about it from Timothy Wong, the technical director of New York City–based ecofriendly pest-management company M&M Pest Control, when we asked him about bedbug mattress protectors and he pointed to SafeRest’s covers as the best. Wong typically recommends the brand’s Premium Zippered Bedbug Proof Mattress Encasement to all his clients. However, he notes that all of SafeRest’s covers are completely waterproof, hypoallergenic, and machine washable. And because this fitted-sheet style is easier to put on and remove than an encasement-style protector, I’ve named it our top pick.
This particular SafeRest cover is made of cotton terry over polyurethane, giving it a soft, cozy feel. Two Strategist staffers, writer Lauren Ro and senior editor Jen Trolio, are longtime users; Ro says that after five years, her beloved Avocado mattress looks “pristine” beneath it. While she alternates between this protector and another one from Linenspa, she says she prefers the SafeRest because it is softer. Trolio has purchased it multiple times, for her own bed as well as her kids’ beds, and is “relieved to report” it has kept her home’s mattresses clean and dry after countless potty-training leaks and corresponding trips through the washer and dryer. She appreciates that it doesn’t create any crinkly plastic noise under the sheets, which would be “an absolute deal-breaker.” Having tested this protector on my own bed, I agree with Ro and Trolio about its soft feel and lack of “swishiness.” To put the waterproofing through its paces, I poured a cup of water onto the protector; it soaked into the terrycloth top layer, but didn’t make it through to the mattress at all, thanks to the polyurethane backing.
The one possible con for this topper is sleeping warm. While cotton terry can allow for breathability, it isn’t the best material for moisture-wicking nor does it provide much temperature regulation. (Consider the classic cotton terry bathrobe, for example: absorbent and cozy but not especially well known for being cooling and breezy.) Trolio says she runs cold, and hasn’t noticed any issues, but says her “hot water bottle of a 6-year-old” also sleeps on this protector without complaint. With that said, if cooling features are a high priority for you, you might want to consider the Coop Sleep Goods protector recommended below.
Best (less expensive) mattress protector overall
Fabric: Polyester blend over polyurethane | Protective qualities: Waterproof | Style: Fitted sheet | Pocket depth: 22 inches | Care instructions: Machine wash and tumble dry
Former Strategist writer Latifah Miles has used this budget-friendly, polyester-blend mattress protector on her tween son’s bed for over two years. “He seems to get a thrill out of trying to balance open cups on his bed,” she says, and the protector has prevented “everything from water to hot chocolate” from seeping into his mattress. Miles adds that the texture of the fabric layer also creates a slight traction that helps to keep her son’s actual fitted sheet in place. Unlike our top-pick SafeRest, the Linenspa uses polyester instead of more natural cotton for its fabric layer (even though the product name and description say “cotton terry,” the care tag says otherwise). It is also not hypoallergenic or OEKO-Tex-certified. However, it has a greater depth of 22 inches, so it’s a good option if your mattress is especially tall, and its low price makes it very affordable to buy in multiples. Trolio has this protector for that very reason, keeping an extra twin-size Linenspa on hand for “inconvenient laundry” moments, when she is in a rush to get bedding back onto her two daughters’ beds but wants to make sure their mattresses are never left bare.
Best fully encased mattress protector
Fabric: Cotton terry over a waterproof membrane | Protective qualities: Bedbug protection, waterproof, hypoallergenic | Style: Full encasement | Pocket depth: Available in a variety of depths, up to 18 inches | Care instructions: Machine wash and tumble dry
This mattress encasement, which Wong recommends to his pest-control clients, is also by SafeRest, the maker of our top-pick mattress protector above. Made of breathable cotton terry over a waterproof membrane, it is fully waterproof and has a specially designed zipper that Wong especially likes for bed bug protection. White adds that for any zippered, fully-encased mattress cover, the “zipper and zipper end-stop should have research demonstrating that it works at preventing bed bugs from getting in and out,” and SafeRest’s bed bug mattress protectors are independently lab-tested and certified to be bedbug-proof. This encasement is OEKO-TEX-certified, which means it’s free of PVC and vinyl. It comes in a range of depths, from six to nine inches on the low end to 15 to 18 on the high end, to ensure a good fit for whatever mattress you have.
Strategist writer Bella Druckman tested this protector while reporting on the best anti-bed-bug covers and named it her No. 1 pick. Druckman says it doesn’t make any crinkly noise when she moves, thanks to the cotton terry top layer. She also noted that the protector has an extra Velcro flap over the end of the zipper to ensure that there aren’t any openings where bedbugs could crawl through. Druckman adds that even though this protector fully encases the mattress — meaning you have to get it aligned on all six sides and then zip it closed — it was easy enough for her to put on by herself.
Best (less-expensive) fully encased mattress protector
Fabric: 100 percent polyester over a waterproof layer | Protective qualities: Waterproof | Style: Full encasement | Pocket depth: 10 inches or 12 inches | Care instructions: Machine wash and tumble dry
NYC Bed Bug Inspections owner John H. Brickman often recommends Linenspa’s Zippered Mattress Encasement to his clients as an affordable cover to protect mattresses and box springs or mattress foundations from dust mites and bedbugs. Made of durable polyester, it is also waterproof on all sides, as well as machine-washable. The potential trade-off of Linenspa’s lower-priced fully encased mattress protector, however, is that while it comes in two different depths, it tops out at 12 inches and won’t fit especially tall mattresses.
Best cooling mattress protector
Fabric: Polyester-polyethylene blend over polyurethane | Protective qualities: Waterproof | Style: Fitted sheet | Pocket depth: 15 inches | Care instructions: Machine wash and tumble dry on low
Made by Coop Sleep Goods (which also makes one of our favorite pillows), this mattress protector is cooling, waterproof, and comfortable to sleep on. It has a polyurethane backing, like most of the other protectors on this list, but the top is made from a blend of polyester and polyethylene. The polyethylene is what gives the topper its cooling properties — it’s a synthetic material that has a cool-to-the-touch feel. If I run my hand across the top of this protector, it does feel noticeably cooler than other protectors I’ve tested. When I added a fitted sheet on top, the cooling effect was slightly reduced, but I think it still kept me from overheating. The polyester-polyethylene blend is a jacquard knit, so it feels smooth and obscures any crinkling sensation that could come from the polyurethane backing underneath. The protector also doesn’t make any noise.
I tested this mattress protector’s waterproofing by pouring a cup of water onto it, and quickly realized that it’s basically hydrophobic; the water beaded up on the surface of the protector, rather than soaking into the top layer and then stopping at the polyurethane backing (as I’ve seen in most other protectors). Even after a few minutes, the water droplets hadn’t absorbed into the fabric — there certainly wasn’t any water reaching the mattress. During my test, some of the water I poured onto the protector started to roll off the sides of the mattress since it beaded instead of seeping in, but I don’t think that would be an issue in most real-life scenarios, since the bed would likely have sheets and other bedding that would soak up some of the liquid. I plan to continue testing this protector long term, especially to see if this water-repelling quality holds up after I’ve washed and dried it a few times.
Best (less expensive) cooling mattress protector
Fabric: 60 percent polyester, 40 percent bamboo-derived viscose rayon over polyurethane | Protective qualities: Waterproof | Style: Fitted sheet | Pocket depth: 18 inches | Care instructions: Machine wash and tumble dry
While I like the Coop protector above for its cool-to-the-touch cover and super-effective waterproofing, it is fairly expensive. As a more affordable alternative, Coop’s Ultra Tech mattress protector is about $30 cheaper and still has some cooling properties. This is another mattress protector that Trolio uses in her own home, in rotation with our top pick SafeRest and a backup Linenspa. Its top layer is a blend of polyester and bamboo-derived viscose rayon, the latter of which works well to regulate temperature and wick away moisture — key if you do run warm. However, this protector doesn’t have the “physically cool” feel of polyethylene, so I’d still go with the Ultra Cool protector above if cooling is more important to you than budget.
Compared to the looped cotton-terry fabric on the SafeRest, which Trolio says is a little “nubbier” in feel (kind of like a bath towel), the Coop protector has a smoother finish. Trolio owns it in a twin size and says she typically uses it during the summer for her younger daughter, who sleeps hot. She says it does feel slightly cooler than the SafeRest. But most importantly, Trolio says its polyurethane backing has protected her daughter’s mattress through Pull-Up leaks and water-bottle spills, held up well in the washer and dryer, and does not make any disruptive crinkling sounds.
Best mattress protector for people with allergies
Fabric: 100 percent cotton top layer over 88 percent polyester, 12 percent nylon | Protective qualities: Hypoallergenic, moisture wicking, bedbug protection, waterproof | Style: Full encasement | Pocket depth: 15 inches | Care instructions: Machine wash and tumble dry
An allergen-specific mattress protector is designed to keep irritants like dust mites and pet dander from collecting on and inside your mattress. Sleep consultant Kelly Murray named this AllerEase protector as her “No. 1 recommendation” because along with protecting against bedbugs and allergens, it is comfortable and breathable. Constructed from a cotton top layer over a waterproof poly-blend layer, the zippered-encasement construction is designed to make the cover impenetrable, which White says is “the more important aspect of encasements” and makes them actually work.
Best organic mattress protector
Fabric: 100 percent organic cotton over polyurethane | Protective qualities: Waterproof | Style: Fitted sheet | Pocket depth: Available in two sizes, up to 22 inches | Care instructions: Machine wash and tumble dry
“Organic” is an admittedly tricky term when it comes to mattress protectors, since any reliably waterproof protector will contain vinyl or polyurethane, a.k.a. plastic. However, I think most people seeking organic bedding really just want to be sure what they’re sleeping on every night is safe, for themselves and/or the environment. Avocado has built its entire brand around mattresses and bedding that are as human- and earth-friendly as possible, including this Organic Waterproof mattress protector.
Unlike other Avocado products, this protector does have some plastic in it — a layer of polyurethane between two layers of certified-organic cotton. That polyurethane layer is what makes the protector waterproof (a quality that would be challenging if not impossible to achieve with solely natural materials). What sets this protector apart is the sandwich-style design, which means the polyurethane layer never comes in contact with your mattress. In addition to the cotton being certified organic, this protector is Greenguard Gold certified for low chemical emissions, is formaldehyde-free, and is Made Safe certified to be free from toxic materials. That’s not to say that other mattress protectors on the market are definitely toxic or harmful, but if you want extra peace of mind, these certifications exist to provide it.
I’ve been sleeping with this protector on my own bed at home for a few months, and I like how soft the cotton is. To test the waterproofing, I poured a cup of water directly onto it; as with the SafeRest (my best overall pick), the water soaked into the fabric top layer, but didn’t seep through the polyurethane layer at all, so my mattress stayed completely dry.
The protector comes in two pocket depths (“standard,” which fits mattresses six to 16 inches tall, and “deep,” which fits mattresses up to 22 inches tall) — I have the standard, and it easily fits around both my mattress and mattress topper. When lying down on it, I noticed a very slight crinkly feeling through my sheets. But even though I felt it, the crinkling didn’t cause noise, which is crucial for me — I can take a slightly crunchy feel, but the sound drives me bananas. Despite that, I like how otherwise “natural” this protector is.
Best mattress protector for nighttime potty training
Fabric: Bamboo, rayon, and polyester fibers | Protective qualities: Hypoallergenic, waterproof | Style: Fitted sheet | Pocket depth: Not listed | Care instructions: Disposable
Parents in the throes of nighttime potty training will attest to the amount of laundry that can pile up after an accident. Meyer and Allison Jandu, owner and founder of Potty Training Consultant, both suggest these disposable waterproof bedsheets for anyone who is wetting the bed often. Each package contains one fitted sheet with five waterproof top layers. The top four layers are “peel-away,” so if an accident happens, you can just peel a layer off, and the next layer is ready to go, Meyer explains. If you are dealing with frequent accidents, the layers are comfortable enough that you can forego a regular fitted sheet on top, so you’ll only have to remove a single layer when it’s time to change bedding. The sheets are considered disposable and not meant to be laundered, but if you are concerned about their environmental footprint, Jandu notes that “the temporary use of Peelaways is about equivalent to the water and laundry detergent usage from multiple bedding washes.” They come in multiple sizes to fit crib, twin, twin XL, full, queen, and king mattresses.
Best crib mattress protector
Fabric: 100 percent polyester | Protective qualities: Waterproof | Style: Fitted sheet | Pocket depth: 9 inches | Care instructions: Machine wash and tumble dry
Designed to keep diaper explosions, bottle spills, and general moisture away from your baby’s crib mattress, this budget-friendly, no-frills mattress protector is waterproof and machine washable. It’s sized to fit a standard crib mattress, at 28 inches by 52 inches, with deep corner pockets that ensure the protector won’t slide off the mattress. Many reviewers note that it’s durable and quiet, works well, and is easy to clean, which are all essential for babies. You can also purchase it in a two-pack (and save a few bucks on each) if you want to have a backup on hand.
