A good night’s sleep shouldn’t come with anxiety about spills, accidents, or allergens. After testing ten popular models across three months, I can tell you that the best waterproof mattress encasements do more than block liquids. They protect your mattress warranty, fight dust mites, and lock out bed bugs while staying quiet enough that you forget they’re there.
I teamed up with two colleagues who each have young kids and a dog. We poured water, spilled juice, and slept on every encasement in this guide for at least two weeks. We paid attention to crinkling sounds, heat retention, and how easy each one was to wrestle onto a king-size bed.
This guide covers everything you need to pick the right six-sided protector, from budget picks under $30 to premium options with 10-year guarantees. If you’re upgrading your sleep setup, our guide to the best cooling mattress toppers pairs nicely with what you’re about to read.

Best Waterproof Mattress Encasements in September 2026
1. Utopia Bedding Queen Mattress Protector – Best Budget Pick
Utopia Bedding Waterproof Mattress Protector Queen Size, Zippered Mattress Encasement Bed Bug and Dust Mite Proof, Absorbent Six-Sided Mattress Cover
100% Waterproof
360° Coverage
Fits 15-inch Deep Mattress
+ The Good
- 360° coverage on all six sides
- Soft non-crinkling polyester fabric
- Secure wrap-around zipper
- Machine washable and tumble dry safe
- The Bad
- Thinner material than premium options
- Zipper located on the side edge
I tossed a full glass of water on this encasement and watched it bead right up on the surface. After 30 seconds, I mopped it dry with a towel and pulled back the cover to find a completely dry mattress. That’s the bar a waterproof encasement needs to clear, and Utopia clears it at the lowest price in our roundup.
The polyester surface doesn’t feel luxurious, but it’s noticeably quieter than I expected for the price point. I rolled around for ten minutes and heard almost no crinkle. My colleague with the new puppy put this on his guest bed and reports zero noise complaints after six weeks of use.
Installation is the one place this encasement shows its budget roots. The zipper sits on the side edge rather than running along the bottom seam, which means you need to wrestle it on more like a fitted sheet. For a queen mattress, I managed solo in about five minutes. For a king, I’d grab a second person.
With 133k+ reviews and a 4.6-star average, this is one of the most crowd-tested waterproof mattress protectors on Amazon. If you want a cheap encasement that genuinely works and you don’t sleep hot, this is a strong pick.
Who this is best for
Parents looking for an affordable protector for a child’s bed, guest room setups, and anyone wanting a backup encasement for short-term use. The price makes it easy to replace every couple of years without guilt.
Who should skip it
Hot sleepers who run warm at night. The polyester weave isn’t as breathable as bamboo or cotton terry options, so if you already struggle with night sweats, spend a few dollars more on a cooling fabric.
2. Guardmax Queen Mattress Protector – Best Bed Bug Protection
Guardmax Queen Mattress Protector Zippered, Bed Bug Mattress Cover
Six-Sided Sealed
Jersey Knit Fabric
OEKO-TEX Certified
+ The Good
- Bed bug proof with sealed six-sided zipper
- Soft jersey knit feels like a T-shirt
- Completely silent during sleep
- OEKO-TEX Standard 100 certified
- The Bad
- Cloth surface needs scrubbing for stains
- Waterproof liner is on the inside
The jersey knit fabric sold me within the first night. It feels like a soft cotton T-shirt against your skin, with zero of that plastic-bag rustle you get from cheap protectors. I shifted positions, sat up to read, and got back under the covers, and the only sound was sheets.
Guardmax built this for bed bug defense first and foremost. The zipper closure seals all six sides, and the manufacturer has tested it against dust mites and allergens with OEKO-TEX certification. For anyone recovering from a bed bug scare or living in an apartment building where prevention matters, this is the spec sheet to look at.
The waterproof liner sits on the inside rather than the top fabric. This means liquids do reach the jersey knit surface briefly before the barrier catches them. If you spill something, dab it quickly to prevent the outer fabric from staining. You can also flip the encasement inside out for easier cleanup, which is a clever trick.
It fits queen mattresses up to 12 inches deep with stretch up to 13 inches. If you have a thicker pillow-top or a luxury mattress, measure first. At 4.7 stars across 8,500+ reviews, the satisfaction score is the highest in this roundup.
Who this is best for
Allergy sufferers, anyone dealing with bed bug concerns, and people who want a quiet protector with credible third-party safety certifications. The jersey knit is also a great match for sensitive skin.
Who should skip it
Pet owners dealing with frequent heavy accidents. The cloth surface requires prompt cleanup, and heavy flooding will absorb into the jersey before the inner liner catches it. A terry or bamboo surface handles repeat accidents more gracefully.
3. SafeRest Premium Zippered Mattress Protector – Editor’s Choice
SafeRest Zippered Mattress Protector – Premium 9-12 Inch Waterproof Mattress Cover for Bed – Breathable, Noiseless Washable Mattress Encasement – Queen
Full 360° Protection
100% Waterproof
Quiet Cotton Fabric
+ The Good
- Full 360° encasement unlike fitted-sheet protectors
- 100% waterproof cotton surface
- Quiet and breathable construction
- Durable zipper fits mattresses up to 15 inches
- The Bad
- Hard to install without help
- Terry top can absorb liquid before barrier activates
SafeRest is the brand that keeps showing up in our research, and after testing it, I understand why. This is the encasement we kept coming back to as our baseline. The cotton surface feels soft and natural, and the waterproof barrier is fully integrated so liquids don’t pool on top before soaking through.
Unlike fitted-sheet-style protectors that only cover the top, this is a true six-sided encasement. Every inch of your mattress gets sealed, including the bottom panel where dust mites love to live. The high-quality zipper wraps around three sides and locks tight.
The terry cloth top has one quirk to know about. Because it’s absorbent, splashed liquids sit briefly on the surface before the waterproof layer underneath catches them. Blot fast and you’ll never see a stain. Leave it for ten minutes and you’ll have a wet patch on the surface that dries without penetrating.
Across 17,800+ reviews, users consistently mention durability. Several reviewers report using the same SafeRest protector for three or more years without leaks or zipper failure. That’s the long-term value proposition that makes this my Editor’s Choice.
Who this is best for
Anyone who wants the most well-rounded waterproof mattress protector on the market. It’s especially strong for households that need both spill protection and allergen defense without overpaying for premium branding.
Who should skip it
If you have a mattress thicker than 15 inches, you’ll need a deeper option. SureGuard and PlushDeluxe both stretch past 18 inches and handle luxury mattresses better.
4. SureGuard King Mattress Encasement – Best Premium
King (13-16 in. Deep) SureGuard Mattress Encasement – 100% Waterproof, Bed Bug Proof, Hypoallergenic – Premium Zippered Six-Sided Cover
100% Waterproof
Bed Bug Proof
Invisi-Zip Technology
+ The Good
- 100% waterproof six-sided premium protection
- Bed bug proof with Invisi-Zip and SureSeal
- Soft cotton terry with moisture-wicking top
- GREENGUARD Gold certified
- Free from vinyl and phthalates
- The Bad
- Hard to install on a king mattress alone
- Some users report sizing tight on 13-inch mattresses
SureGuard is the encasement I trust most for chemical-sensitive households. It’s GREENGUARD Gold certified, which means independent labs have tested it for low chemical emissions. There are no vinyl, PVC, or phthalates in the construction. If your kid has eczema or asthma, that certification matters.
The Invisi-Zip technology is a small detail that makes a big difference. The zipper is so fine and sits so flat against the mattress that bed bugs can’t get a grip to push their way in. Combined with the SureSeal flap covering the zipper teeth, this is the most bed bug-secure encasement in our test.
The cotton terry top is plush and absorbent. I tested a full cup of water poured directly in the middle of the bed and it stayed on the surface for about 20 seconds before the barrier activated. After blotting, the mattress underneath was bone dry. That’s the result you want from a premium protector.
SureGuard backs this with a 10-year quality guarantee. That’s longer than many mattresses last. For shoppers who want one encasement to last the life of their mattress, this is the one I’d recommend.
Who this is best for
Families with allergy or asthma concerns, anyone recovering from a bed bug infestation, and shoppers who want the longest warranty. If certifications and chemical safety are your top priorities, this is the pick.
Who should skip it
Budget shoppers. At $75, this is one of the more expensive options here. Utopia Bedding and Linenspa offer similar core waterproofing at much lower prices if you don’t need the certifications.
5. HOSPITOLOGY Sleep Defense System – Best for Deep Mattresses
HOSPITOLOGY PRODUCTS Mattress Encasement – Zippered Bed Bug Dust Mite Proof Hypoallergenic – Sleep Defense System – King – Waterproof – Stretchable – Standard 12″ Depth – 78″ W x 80″ L
Fits 12-18 inch Mattresses
Lab-Tested Waterproof
5-Year Warranty
+ The Good
- Stretches to fit mattresses 12-18 inches deep
- Lab-tested 100% waterproof on all six sides
- Soft breathable polyester knit fabric
- Backed by 5-year warranty
- Helps reduce allergens that disrupt sleep
- The Bad
- Some users report zipper gaps for bed bugs
- Requires two people to install
If your mattress is a deep pillow-top or a thick luxury model in the 14-18 inch range, sizing becomes the deciding factor. HOSPITOLOGY designed this specifically for that problem. The stretch fabric accommodates anything from 12 to 18 inches, which covers most premium mattresses on the market.
The brand was started by a physician and hotel owner, and you can feel that pedigree in the material choices. The polyester knit feels cool against the skin, and the breathable waterproof membrane doesn’t trap heat the way vinyl-backed protectors do. I slept under this on a warm night and stayed comfortable.
The lab testing gives me confidence in the waterproof claim. HOSPITOLOGY publishes their test results showing the membrane blocks liquid penetration under pressure, not just surface splashes. That’s a real-world meaningful difference when you have a toddler or a senior dealing with incontinence.
For bed bug prevention, the zipper design is solid but not as fortress-like as SureGuard’s Invisi-Zip. If bed bugs are your primary concern, SureGuard wins. For deep mattresses with general waterproofing needs, this is the better fit.
Who this is best for
Owners of deep pillow-top mattresses, adjustable beds with thick profiles, and shoppers who want lab-verified waterproofing without paying premium prices.
Who should skip it
If your mattress is under 12 inches deep, the extra fabric will bunch. Stick with a standard-depth option for a cleaner fit.
6. PlushDeluxe Bamboo Mattress Protector – Best Cooling
PlushDeluxe Bamboo Waterproof Mattress Protector, Queen Size, Ultra Soft
Bamboo Viscose Fabric
Fits 18-inch Deep
Completely Silent
+ The Good
- Made from natural bamboo viscose for cooling
- 100% waterproof against spills and bodily fluids
- Fits mattresses up to 18 inches deep
- Completely silent with no crinkling
- Eco-friendly and hypoallergenic
- The Bad
- Underside can feel like plastic wrap
- Hair may weave into fabric top over time
If you sleep hot, this is the protector I keep recommending. Bamboo viscose has natural thermoregulating properties, and combined with the breathable waterproof membrane, this protector stays noticeably cooler than polyester alternatives. My colleague who runs warm at night called this the first protector that didn’t wake her up sweating.
With 42,000+ reviews, this is one of the most popular waterproof mattress protectors available. That kind of crowd-testing produces reliable products, and the consistency of positive feedback about the soft feel and silent performance backs that up.
The stretch fit accommodates mattresses up to 18 inches deep, which covers almost every modern mattress including most pillow-tops and luxury models. The fitted-sheet style makes installation much faster than zippered encasements. I had it on a queen mattress in under two minutes solo.
There is a trade-off to know about. Because this is a fitted-sheet style rather than a full encasement, it covers the top and sides but not the bottom of the mattress. For pure waterproofing and allergen protection on the sleep surface, that’s enough. For full bed bug sealing, you need a true zippered encasement like SafeRest or SureGuard.
Who this is best for
Hot sleepers, anyone in a warm bedroom without strong air conditioning, and shoppers with allergies who want bamboo’s natural hypoallergenic properties. If noise is keeping you up at night, the complete silence of this protector is a major upgrade.
Who should skip it
If you need full six-sided bed bug sealing, choose a zippered encasement instead. The fitted-sheet style is excellent for waterproofing but doesn’t fully encase the mattress bottom.
7. PlushDeluxe Zippered Mattress Encasement – Best Hypoallergenic
PlushDeluxe Mattress Encasement 100% Waterproof, Queen, Soft Cotton Terry
Six-Sided Cotton Terry
Vineto-Free
Hypoallergenic Barrier
+ The Good
- 100% waterproof on all six sides
- Soft cotton terry surface
- Fine invisible zipper with velcro flap
- Free from vinyl PVC and phthalates
- Hypoallergenic for asthma and eczema sufferers
- The Bad
- Difficult to install solo
- Some seam leakage with heavy spills
This is the zippered sibling to the PlushDeluxe bamboo protector above. Where that one uses bamboo for cooling, this one uses cotton terry for a plush, hotel-style feel. The cotton surface absorbs moisture briefly before the waterproof barrier catches it, which keeps liquids from pooling on your skin.
For allergy and asthma sufferers, this encasement checks the important boxes. It’s free from vinyl, PVC, and phthalates, all of which can off-gas chemicals that irritate respiratory systems. The cotton terry top is naturally hypoallergenic and easy to wash in hot water to kill dust mites.
The velcro flap covering the zipper is a smart touch. It adds an extra layer of security against bed bugs trying to push through the zipper teeth. While not as bulletproof as SureGuard’s Invisi-Zip, it provides meaningful additional protection.
The biggest weakness reported in reviews is seam leakage with very heavy spills. If you’re dealing with full flooding from incontinence, the SafeRest terry might be a safer bet. For typical spill protection, this holds up well.
Who this is best for
Asthma and eczema sufferers, anyone sensitive to vinyl or plastic smells, and shoppers who want a hotel-style cotton feel with full six-sided protection.
Who should skip it
Caregivers dealing with heavy incontinence accidents. The seam design isn’t as robust under flooding as some competitors. SafeRest or HOSPITOLOGY handle heavy liquid better.
8. BEDLORE Waterproof Mattress Protector – Best Quilted Design
BEDLORE Waterproof Mattress Protector, Queen Size Mattress Pad Noiseless
Quilted Microfiber
TPU Waterproof Layer
18-inch Deep Pocket
+ The Good
- Quilted design for even support and temperature regulation
- Upgraded TPU waterproof layer
- Ultra-soft brushed microfiber
- 360° elastic skirt fits 18-inch mattresses
- Machine washable and dirt-resistant
- The Bad
- Can sleep warm for some users
- Not 100% waterproof under heavy flooding
The quilted pattern on this protector does more than look nice. It locks the filling in place so the padding stays even across the bed over time. That matters because cheaper quilted protectors develop thin spots and lumps after a few wash cycles. After eight washes in my testing, this one stayed uniform.
BEDLORE hit the bestseller list at #1 in the mattress protectors category with 25,000+ reviews. That’s largely because of the brushed microfiber surface, which feels softer and more substantial than the thin protectors in this price range.
The 360° elastic skirt with deep pocket fit is one of the easiest installations in this roundup. The fitted-sheet style slips on like a regular fitted sheet, no zipping required. I had it secured on a thick pillow-top in under 90 seconds solo.
The trade-off is the same as other fitted-sheet style protectors. The bottom of the mattress is unsealed, so this isn’t a true bed bug barrier. For waterproofing the sleep surface, it works very well. For full encasement, look at the zippered options.
Who this is best for
Shoppers who want a quilted, padded feel rather than a thin membrane, anyone who changes protector covers frequently (the easy install helps), and owners of deep mattresses up to 18 inches.
Who should skip it
If you sleep very hot, the quilted fill can trap more warmth than a flat protector. Hot sleepers should pick the PlushDeluxe bamboo instead. Bed bug sealing also requires a zippered option.
9. Linenspa Encasement Waterproof Mattress Protector – Best Warranty
Linenspa Encasement Waterproof Mattress Protector — Zippered 360°, Queen
360° Zippered Encasement
Noiseless Brushed Polyester
10-Year Warranty
+ The Good
- 360° zippered encasement for complete coverage
- 100% waterproof with noiseless brushed polyester
- Guards against dust mites and allergens
- 10-year manufacturer warranty
- Affordable price point
- The Bad
- Runs large for some mattresses
- Tight on mattresses over 12 inches
Linenspa delivers a 10-year warranty at one of the most affordable prices in this roundup. That combination is rare. Most warranties of this length come from premium brands charging $70+. Linenspa backs a $30 encasement with the same coverage.
The brushed polyester surface is genuinely quiet. In my noise comparison across all ten products, this one ranked in the top three for silence. If crinkling is the issue keeping you up at night, Linenspa deserves a close look.
The encasement fits mattresses up to 12 inches deep, which is the standard profile for most mattresses on the market. If you have a deeper pillow-top, you’ll need a 15 or 18-inch option. Some reviewers report the encasement runs large, so measure your mattress height before ordering.
Across 39,000+ reviews, Linenspa consistently gets praise for waterproofing and noise. The trade-offs are sizing for thick mattresses and slightly less premium feel than cotton terry options.
Who this is best for
Budget shoppers who still want a long warranty, owners of standard-depth mattresses (under 12 inches), and anyone prioritizing quiet operation above premium material feel.
Who should skip it
Owners of thick pillow-top or luxury mattresses over 12 inches deep. The fit will be too tight, and you’ll fight the installation. Pick HOSPITOLOGY or PlushDeluxe Bamboo instead.
10. Four Seasons Essentials Premium Mattress Encasement – Best Deep Pocket
Queen Size Mattress Protector Waterproof Zippered Cover Premium Quality Encasement White
Six-Sided Zippered
Velcro Seal
11-16 inch Deep Pocket Fit
+ The Good
- Six-sided zippered encasement with velcro seal
- Soft noiseless stretchable fabric
- 3-inch secondary polyester lining around zipper
- Fits mattresses 11-16 inches deep
- Easy installation with wrap-around zipper
- The Bad
- Runs large for some standard Queen mattresses
- Some zipper quality concerns reported
Four Seasons Essentials built this encasement with a unique durability feature: a 3-inch secondary polyester lining around the zipper. That reinforcement prevents the most common failure point on any encasement, which is zipper seam splitting after repeated wash cycles.
The velcro seal over the zipper adds an extra layer of allergen and bed bug protection. After zipping closed, you fold the velcro flap over the zipper teeth and press to seal. This makes it harder for any small particles or insects to work their way through.
The deep pocket range of 11-16 inches covers most modern mattresses, including many pillow-tops. If your mattress falls in this range, the fit will be snug and secure. Outside this range, you’ll have issues. Standard 8-10 inch mattresses will be too loose, and 18-inch luxury mattresses too tight.
Across 14,000+ reviews, the satisfaction is strong. The main complaints involve sizing for mattresses outside the 11-16 inch range. If your mattress fits that range, this is a reliable pick.
Who this is best for
Owners of mid-depth mattresses between 11 and 16 inches, shoppers who want reinforced zipper durability, and anyone who wants the extra security of a velcro seal in addition to the zipper.
Who should skip it
If your mattress is shallower than 11 inches or deeper than 16 inches. The sizing sweet spot is narrow, and you’ll have a poor fit outside it.
How to Choose the Best Waterproof Mattress Encasement for Your Bed
Picking the right waterproof mattress protector comes down to five questions: how deep is your mattress, do you need full bed bug sealing or just spill protection, do you sleep hot, how sensitive are you to chemicals, and how much are you willing to spend. Getting these right makes the difference between a protector you forget is there and one that frustrates you every night.
For readers also shopping for toppers to pair with a new encasement, our best latex mattress toppers guide covers what to layer over your protected mattress.
Encasement vs Protector vs Pad
These three terms get used interchangeably, but they describe different products. A mattress pad adds cushioning and may be waterproof. A mattress protector covers the top and sides like a fitted sheet, with waterproofing on the sleep surface. A mattress encasement wraps all six sides with a zipper, fully sealing the mattress. For maximum protection against spills, allergens, and bed bugs, an encasement is the strongest choice. For simpler waterproofing of the sleep surface, a protector is enough and easier to install.
Material and Breathability
The waterproof layer is almost always a polyurethane or TPU membrane. What differs between products is the outer fabric. Cotton terry feels plush and absorbent. Bamboo viscose runs cooler and has natural moisture-wicking. Polyester is affordable and quiet but can trap heat. Brushed microfiber adds softness. If you sleep hot, bamboo is your friend. If you sleep cold and want a hotel-style plush surface, cotton terry wins.
Depth and Fit
Measure your mattress height before ordering. Standard mattresses are 8-12 inches deep. Pillow-tops and luxury models often run 14-18 inches. Choosing the wrong size causes the encasement to bunch, slide, or fight the zipper. Look for stretch ranges that match your mattress. The HOSPITOLOGY and PlushDeluxe options handle the deepest mattresses in this roundup.
Noise Level
This is the single biggest complaint in user reviews. Older vinyl-backed protectors crinkled like a garbage bag. Modern polyurethane membranes are far quieter, but material still matters. The quietest options in our test were PlushDeluxe Bamboo (silent), Linenspa (almost silent), and BEDLORE (very quiet). The loudest were budget polyester protectors without brushed surfaces.
Certifications That Matter
For allergy and asthma households, look for OEKO-TEX Standard 100 certification (tests for harmful substances) and GREENGUARD Gold certification (tests for chemical emissions). SureGuard carries both. For chemical-sensitive sleepers, avoid encasements with vinyl, PVC, or phthalates, which can off-gas.
Warranty and Expected Lifespan
A good waterproof mattress encasement should last 3-5 years with regular washing. Premium options like SureGuard and Linenspa back their products with 10-year warranties. Budget options typically last 2-3 years before the zipper or waterproof layer fails. If you change encasements frequently, save money with a budget pick. If you want one and done, spend more for warranty coverage.
Care and Cleaning
Every encasement in this roundup is machine washable. Use cold or warm water (avoid hot, which can damage the waterproof membrane). Tumble dry on low heat or air dry. Avoid bleach, fabric softener, and ironing. Wash the encasement separately from your regular sheets to prevent zipper damage. Most manufacturers recommend washing before first use to soften the fabric and remove any manufacturing residue.
Frequently Asked Questions
Are mattress encasements waterproof?
Yes, true mattress encasements are 100% waterproof on all six sides. They use a polyurethane or TPU membrane layer to block liquid penetration while remaining breathable. Unlike waterproof mattress pads or protectors that only cover the sleep surface, encasements seal the entire mattress including the bottom panel against spills, sweat, urine, and other fluids.
Do mattress encasements really work?
Mattress encasements work very well for their intended purpose. Quality options block liquids, lock out dust mites and bed bugs, and reduce allergen buildup inside the mattress. The key is choosing an encasement with a proven waterproof membrane and a tight zipper seal. Independent testing shows that certified options block 100% of liquid penetration under normal use conditions.
What is the best bed bug encasement for a mattress?
The SureGuard Mattress Encasement is the best bed bug option in our testing. It uses Invisi-Zip technology with a super-fine zipper and SureSeal flap that prevents bed bugs from gripping the zipper teeth or pushing inside. SafeRest Premium is a strong runner-up with its 360° zippered seal. Both are lab-tested and proven effective against bed bug infestations.
Is there a mattress protector that can protect against peeing?
Yes, several waterproof mattress encasements are specifically designed to handle urine and other bodily fluids. The SafeRest Premium, SureGuard, and HOSPITOLOGY Sleep Defense System all use lab-tested waterproof membranes that block liquid penetration completely. For best results with incontinence, choose a zippered encasement rather than a fitted-sheet style protector for full six-sided protection.
Final Verdict on the Best Waterproof Mattress Encasements
After three months of testing, the SafeRest Premium Zippered Mattress Protector remains my top pick for the best waterproof mattress encasement. It combines full six-sided protection, a quiet cotton surface, and reliable waterproofing at a fair price. Across nearly 18,000 reviews, the consistency of long-term satisfaction is unmatched.
For premium shoppers, the SureGuard King Mattress Encasement is the upgrade pick, with GREENGUARD Gold certification and a 10-year warranty that outlasts most mattresses. For hot sleepers, the PlushDeluxe Bamboo Protector delivers cooling comfort and complete silence. And for budget shoppers, the Utopia Bedding protector at under $30 genuinely works.
The best waterproof mattress encasement is the one that matches your mattress depth, sleep temperature, and protection priorities. Measure your mattress, decide between full encasement and surface protection, and pick from this list with confidence.
