Finding a mattress cover that genuinely stops urine from soaking into your mattress without making you sleep on a sweaty, crinkly plastic sheet is the central challenge for anyone dealing with bedwetting, incontinence, or a new puppy. Most waterproof covers fail on one of two fronts: they either leak under pressure or turn your bed into a noisy, heat-trapping sauna.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing bedding protection data, pore over lab test results for waterproof barriers, and track real-world customer feedback on how these covers hold up to repeated washing and nightly abuse.
This guide cuts through the marketing noise to help you find the best pee proof mattress cover that balances absolute liquid protection with genuine sleep comfort and easy maintenance.
How To Choose The Best Pee Proof Mattress Cover
Protecting your mattress from urine requires more than a basic, thin waterproof pad. You need a barrier that won’t fail when a bladder fully empties or after a child rolls over. Here are the three non-negotiable factors to consider.
Encasement vs. Fitted Sheet Protector
A fitted sheet-style protector only covers the top and sides, leaving the bottom of your mattress exposed. If urine soaks through the sides or leaks around the elastic edge, it reaches your mattress directly. A zippered encasement wraps around all six sides, creating a sealed cocoon. For bedwetting or incontinence, the six-sided encasement is the only truly pee-proof option because it contains the liquid from every angle.
Fabric Type and Breathability
The top fabric layer determines whether you wake up sweating. Cotton terry is soft, highly absorbent, and quiet, but it can feel warm. Organic cotton adds a chemical-free advantage for sensitive skin. Tencel (lyocell) wicks moisture better than cotton, stays cooler, and is naturally hypoallergenic. Avoid vinyl or PVC-backed covers — they trap heat and produce that loud crinkling sound every time you shift. Look for a TPU (thermoplastic polyurethane) waterproof membrane bonded to a breathable fabric.
Barrier Quality and Washability
The waterproof layer must withstand high-volume liquid events without leaking through seams or corners. A PU (polyurethane) or TPU laminate that is heat-pressed rather than glued-on holds up better to frequent washing. If you plan to wash the cover weekly, check that the manufacturer explicitly states it is machine-washable and dryer-safe without degrading the waterproof coating. A 10-year warranty is a strong indicator of a durable, pee-proof barrier.

In‑Depth Reviews
1. SureGuard Mattress Encasement (King)
The SureGuard Encasement is the gold standard for full, no-compromise pee protection. Its six-sided design wraps the entire mattress in a waterproof, bed-bug-proof cocoon, and the zipper uses Invisi-Zip technology with a tight, fine-tooth closure that seals completely. The 100% cotton terry top layer wicks moisture away and stays noiseless, so you never hear a crinkle or feel a plastic barrier when you roll over. With a 10-year warranty and GREENGUARD Gold certification, this encasement is built for frequent washing and daily abuse.
All five customer reviews rate this cover 4 or 5 stars, with buyers praising its durable fit and the peace of mind it brings. One reviewer noted that it fits a Purple mattress perfectly, while another called it “solace” against leaks. The only caution is to zip slowly and align the edges carefully, though this is common with high-quality encasements. For a primary mattress protector that handles heavy wetting events without fail, this is the top pick.
The 13-to-16-inch deep pocket accommodates most modern mattresses, including memory foam and hybrid models. It blocks allergens, dust, and dander on all sides, making it a strong choice for sensitive sleepers who also need a reliable urinary barrier.
Why it’s great
- Six-sided encasement provides full 360-degree liquid protection
- Cotton terry top is soft, quiet, and moisture-wicking
- 10-year warranty shows confidence in durability
Good to know
- Zipper requires careful alignment to avoid snagging
- Not a stretch-fit; may feel slightly loose on very thin mattresses
2. MATTSHIELD ORIGINAL Organic King Protector
If organic certifications and skin-friendly materials are a priority alongside pee-proofing, this protector from MATTSHIELD ORIGINAL delivers. The top layer is made from organic cotton backed by a waterproof TPU membrane, and the 380GSM 3D air fabric construction adds a plush, quilted feel without bulk. It is free from latex, PVC, and phthalates, and the entire product is OEKO-TEX certified for low chemical emissions. The deep stretch-knit skirt fits mattresses up to 18 inches securely, keeping the fitted sheet taut.
Buyers report zero crinkle noise and no heat buildup, with one reviewer calling it “the best mattress cover” for staying cool. A minor drawback is the weight when washing — the thick surface holds water, making it heavy to handle in a spin cycle and a challenge to dry fully. Still, for those who want a naturally derived fabric against their skin and reliable waterproof protection underneath, this is a standout choice.
The ivory color and soft-hand feel elevate the aesthetic beyond a typical clinical-looking protector. For parents or caregivers concerned about chemicals touching a child’s skin during bedwetting events, this organic pick provides serious peace of mind.
Why it’s great
- OEKO-TEX certified organic cotton top is gentle on sensitive skin
- Thick 380GSM fabric is quiet and plush without crinkle
- Deep 18-inch pocket fits pillow-top and thick mattresses
Good to know
- Heavy when wet; can strain washing machine spin cycle
- Not a full encasement — liquid can still escape around elastic edges
3. Tempur-Pedic TEMPUR-Protect King
This Tempur-Pedic protector uses stretchy fabric with mesh sides and deep pockets to create a snug, custom fit that doesn’t shift or bunch. The patented ThermalSense fabric is lightweight and designed for continuous airflow, keeping the sleep surface breathable even with a waterproof barrier underneath. It is 100% waterproof, effectively blocking spills and pet accidents without any crinkly noise. Multiple customers confirm that even full water bottles dumped on the bed didn’t reach the mattress.
A notable pattern in feedback is that this cover runs large — it fits a standard king mattress with significant overhang, needing a 20-inch-deep mattress to look tidy. One reviewer complained about bunching and stretching after washing, though the majority praise the soft, quiet fabric. The machine-washable and dryer-safe convenience is a major plus for frequent laundering, which is essential when managing accidents.
It is important to note that this is a fitted sheet-style protector, not a full encasement. While its waterproof layer is robust, liquid can still leak out around the bottom edges if the volume is high. For those with a Tempur-Pedic mattress who want a brand-matched, stretch-to-fit protector, this is the top pick.
Why it’s great
- Stretchy mesh sides provide a wrinkle-free, custom-like fit
- ThermalSense fabric breathes well, reducing sweat buildup
- Survived full water bottle spills in real-world tests
Good to know
- Very large fit; best for mattresses 18+ inches deep
- Fitted style — not a full six-sided encasement
4. NORTHERNFARE Tencel Queen Protector
The NORTHERNFARE protector is built around a Tencel jacquard top layer, which is approximately ten times softer than cotton and excels at wicking heat and moisture away from the body. This makes it a smart choice for hot sleepers who also need a waterproof barrier. The triple-layer design combines the cooling Tencel top with an invisible waterproof membrane and a deep 18-inch pocket skirt, keeping everything secure without shifting. OEKO-TEX 100 certification ensures zero harmful chemicals near the skin.
Customer reviews consistently highlight the lack of crinkling, the absence of trapped heat, and the genuine waterproof performance after multiple washes. One user said it outclassed four other “no sound/no sweat” covers they tried. On the downside, the fabric blend is 69% polyester, which may not feel as natural as 100% cotton to some users, and the fitted design leaves the mattress bottom exposed to potential soaking.
For a queen-size bed experiencing nightly bedwetting or post-surgery incontinence, this protector balances premium comfort with strong, noiseless waterproofing. The ability to wash it repeatedly without degrading the waterproof layer makes it a reliable workhorse.
Why it’s great
- Tencel top actively wicks heat for a cool, sweat-free sleep
- No crinkle or plastic noise even after washing
- 18-inch deep pocket fits thick mattresses securely
Good to know
- Polyester blend may not appeal to all-cotton purists
- Fitted protector — not a full encasement
5. CleanRest PRO Presto! Cal King Encasement
This CleanRest model solves the biggest hassle of a full encasement: washing the entire heavy cover. Its top layer unzips completely in under a minute without lifting the mattress, so you can launder only the top portion and leave the bottom base in place. The MicronOne fabric blocks dust mites, bed bugs, and allergens, while the Zip-N-Click 2X locking zipper provides a secure, 360-degree seal. The airflow-oriented design vents body heat and reduces humidity, making it cooler than most fully enclosed protectors.
Reviewers praise the simple installation process using the video guide, the hotel-quality feel, and the soft, noiseless fabric. The main trade-off is the premium price point and the fact that the top is a separate piece requiring its own zipper alignment. For a caregiver managing repeated bedwetting who wants to strip and wash only the soiled portion, this design is a real time-saver and reduces wear-and-tear on the base cover.
The 10-year warranty reinforces the heavy-duty construction. Expect a true six-sided barrier that keeps all liquid trapped inside the encasement, not just the top. This is a specialized but practical solution for high-volume incontinence scenarios.
Why it’s great
- Zip-off top is machine-washable without moving the mattress
- MicronOne fabric is breathable, hypoallergenic, and noiseless
- Zip-N-Click lock offers the most secure 360-degree seal
Good to know
- Premium price reflects the encasement and separate top design
- Requires careful zipper alignment for the top section
6. NORTHERNFARE Tencel King Protector
This King-size version of the NORTHERNFARE Tencel protector brings the same cooling, noiseless, triple-layer waterproof design to a larger bed. The 100% Tencel surface fibers are naturally breathable, drawing moisture and heat away from the sleeper, which is critical for those prone to night sweats or sleeping with a partner who wets the bed. The waterproof barrier is positioned between the Tencel top and the jersey cotton skirt, ensuring zero crinkle and no plastic feel.
Reviews mirror the Queen version — users praise the complete lack of rustling, the soft-to-the-touch fabric, and the effective cooling. One verified buyer said it “doesn’t trap heat or change the feel of my Saatva,” while another tested it against four competitors and declared it the only one that delivered on both silence and dryness. The fitted design is snug on mattresses up to 18 inches deep, though it is not a full encasement, so liquid could theoretically escape the bottom edge if the volume is extreme.
For a King-sized bed needing lightweight, washable, and truly quiet protection, this protector offers a premium experience without a luxury price tag. It is easy to install and remove for weekly washing, making it practical for ongoing use with children or elderly family members.
Why it’s great
- 100% Tencel surface provides superior cooling and moisture wicking
- Triple-layer construction is noiseless and comfortable
- Machine washable and dryer safe without degrading the barrier
Good to know
- Fitted sheet style — not a full six-sided encasement
- Some users may prefer a thicker, quilted feel
7. Purple Waterproof Mattress Protector (King)
The Purple protector is engineered specifically to pair with a Purple GelFlex Grid mattress, providing added stretch that flexes seamlessly with the grid for optimal pressure-relief. The soft-knit top layer is fully waterproof and completely crinkle-free, so the protection is invisible during sleep. It is designed to survive repeated washing without losing its waterproof integrity, a common failure point for cheaper covers. The polyester construction is lightweight and easy to handle.
Customer feedback is almost universally positive: the cover is stretchy, fits Tempur-Pedic and other mattresses well, and survived a half-gallon water spill without a single drop reaching the mattress. The main criticism is the premium price point, though buyers who own a Purple mattress generally consider it a worthwhile investment. One reviewer noted that the waterproofing is “pricey but worth it” after the direct spill test.
Note that this is a fitted protector, not a full encasement, and fits mattresses 8 to 15.5 inches deep. For Purple mattress owners who want unobtrusive, stretch-fit protection that preserves the unique feel of the GelFlex grid, this is the only option that truly matches.
Why it’s great
- Designed to stretch with Purple GelFlex Grid for full pressure relief
- Crinkle-free knit fabric is completely silent and soft
- Proven waterproof performance in extreme spill tests
Good to know
- Only fits mattresses up to 15.5 inches deep
- Fitted style — not a full encasement for maximum containment
