A mattress cover has one real job: keep the mattress dry without making you feel like you’re sleeping on a crisp packet. The best ones do that silently, stay put on thick mattresses, and survive dozens of washes without turning into a crinkly mess. This guide compares nine fitted covers and encasements across those exact daily-use points so you can pick the one that actually fits your bed.

Whether you’re guarding against kids, pets, or just want a cooler sleep surface, the right bed mattress cover balances waterproofing, breathability, and a deep-pocket fit that won’t shift overnight.
Our Picks at a Glance
How To Choose The Best Bed Mattress Cover
Most people shop for a mattress cover only after a spill, an accident, or a pet decides the bed is theirs. Before you buy, focus on three things: how much of the mattress is actually wrapped, how the waterproof layer feels at night, and whether the skirt will grip your specific mattress depth.
Top-only versus full encasement
Basic protectors guard the sleeping surface, but liquids can seep in around the edges and stain the sides of the mattress. A 5-sided or zippered 6-sided encasement fully wraps the mattress, protecting against urine, blood, sweat, and spills from every angle. If you have kids, pets, or a bed you want to keep pristine for years, full coverage is worth the upgrade.
Waterproofing materials and wash durability
The waterproof layer is usually a TPU (thermoplastic polyurethane) film laminated to the fabric. Thicker TPU, like 0.02mm versus the market standard of 0.015mm, tends to hold up through more washes. Cheap protectors can fail after around 20 washes, while thicker layers are built to stay waterproof for 100 or more cycles. Check the care instructions too — most covers are machine washable on cold and tumble dry on low.
Deep pockets and breathable tops
A deep pocket with full elastic or a 360° elastic skirt keeps the cover from shifting on thick mattresses, adjustable bases, or the added height of a topper. For comfort, look for a soft top layer — organic cotton, bamboo viscose, or a knit blend — because that fabric sits directly under your sheets and controls how hot or noisy the cover feels.

In-Depth Reviews
1. LOFE Organic Queen Mattress Protector
Our pick — over 4.5★ from 450+ verified ratings; the strongest balance of quality and price.
The crowd favorite pairs 5-sided waterproofing with an organic cotton top that actually feels soft.
This cover stops liquids from seeping in around the edges by wrapping your mattress in a 5-sided TPU encasement (a waterproof plastic-like layer) that blocks urine, blood, and sweat from kids, pets, or adults. The inner polyester fiber fill adds absorbency, and the 0.02mm TPU layer is designed to survive 100+ washes, versus the market standard of 0.015mm — so it should outlast 10 ordinary covers rather than failing after 20 washes.
The OEKO-TEX-certified organic cotton surface (a label that means the fabric is tested for harmful substances) wins people over, with owners emphasizing how softly padded and noiseless it feels. The 360° elastic skirt fits extra-thick mattresses and adjustable bases, and one buyer fitted it on a king bed about 14 inches deep and called it “way better than the one I had before (which cost 3x as much as this one!)” — also noting the lightly padded top feels quality without being a pain to remove.
The main trade-off is durability uncertainty: some buyers report black spots appearing on the surface, which are cottonseed husks from the organic cotton rather than dirt. If you want a chemical-free organic surface with edge-to-edge protection, this is the strongest balance of comfort and coverage.
What wins owners over
- 5-sided TPU protects edges and sides, not just the top
- 100% organic cotton surface rated for 100+ washes
- 360° elastic skirt stays put on thick and adjustable beds
The trade-offs to know
- Occasional reports of black spots from cottonseed husks
- Durability over time gets mixed reviews
The pick for: anyone who wants full edge protection and a soft organic surface under their sheets.
Think twice if: you’re sensitive to visible surface specks on natural cotton covers.
2. GOPOONY Premium Waterproof Mattress Protector
A 3D air fabric top and an 18-inch deep pocket that stretches to fit mattresses up to 21 inches.
The headline here is the deep pocket: the fitted-sheet style skirt fits all types of mattresses up to 21 inches and keeps the cover from moving. The 3D air fabric is softer and more breathable than ordinary protective covers, and the premium TPU back blocks perspiration, bed wetting, liquids, and stains while staying noiseless.
Families with young kids and pets are the core audience, and the review pages confirm it: owners mention it survived co-sleeping with baby and toddler accidents while the mattress stayed dry, with no chemical smell and no fading after machine washing. It’s comfortably thin — one owner described it as “thin but effective” — which means it disappears under your sheets rather than feeling bulky.
The honest catch is that some owners say the top is not very thick and the fabric runs slightly warmer than a true cooling pad, so don’t expect a dramatic temperature drop. If you have a thick mattress, a topper stack, or just want a quiet, effective barrier that’s easy to swap between washes, this is the one to reach for.
What owners praise most
- Deep pocket fits mattresses up to 21 inches
- Soft, breathable 3D air fabric top
- Machine washable and stays tight after many washes
What to expect
- Not a noticeably cooling top despite the name
- Runs slightly warmer for some sleepers
Best suited to: parents and pet owners with thick mattresses who want a thin, quiet barrier.
skip it if: you’re a hot sleeper expecting a dramatic cooling effect from the top fabric.
3. SafeRest Waterproof Queen Size Mattress Protector
The most-bought cover in this guide, with a cotton terry top that stays quiet and comfy.
SafeRest is the volume king here — the sheer number of verified owners makes its consensus hard to argue with. The sleep surface is 80% cotton and 20% polyester terry cloth, with a 100% polyurethane laminate lining and a stretchable pocket that fits mattresses up to 18 inches deep. Owners describe it as soft, quiet, and free of the crinkle that plagues cheap plastic covers.
The fit is where it shines: it hugs deep mattresses without heat buildup, and the terrycloth layer keeps your sheets from sliding around. Customers note it blocked cat pee and toddler accidents with no mattress damage, washing out cleanly afterward. It’s also a common pick for Airbnb hosts and first apartments precisely because it does the basics so well at a value price.
The split in feedback is water resistance: many find it super waterproof, but enough reviewers point out it’s not actually waterproof that you should treat it as reliable for quick clean-ups rather than a soak-proof barrier. If you want a proven, comfortable daily cover that handles normal spills and accidents, this is the safest bet in the mid-range.
Why it wins crowds
- Cotton terry top feels soft and quiet under sheets
- Fits deep mattresses up to 18 inches
- Machine washable with proven spill-blocking
The honest limit
- Water resistance is mixed — some shoppers say leaks
- Not a full 5-sided encasement
Reach for this if: you want a proven, comfortable daily cover at a value price.
Look elsewhere if: you need guaranteed full-immersion waterproofing for heavy accidents.
4. PlushDeluxe Bamboo Waterproof Mattress Protector
A bamboo viscose top that wicks moisture and slips onto Sleep Number and air-cooled beds.
PlushDeluxe builds its top from bamboo viscose, which wicks away moisture and regulates heat for a fresh, cool sleeping environment. The 60% bamboo / 30% polyester bottom layer gives it a stretchy fitted-sheet grip for mattresses up to 18 inches deep, and the membrane is completely silent — no crinkling sound at all.
What stands out in owner feedback is how well it fits unusual beds. Multiple buyers report it fits Sleep Number’s ClimateCool and Climate Series covers perfectly, preserving the cooling effect at roughly a quarter of the OEM price. Others use it for elderly incontinence care, describing it as fabric-like rather than plastic, with full mattress protection and easy machine washing.
The trade-off splits down the middle on temperature: some owners say it keeps them cool, while others find it extremely hot to sleep on. If you have an air-cooled bed or a memory foam mattress and want a smooth, silent bamboo layer, this fits beautifully — just don’t count on it as your only cooling solution.
What wins people over
- Fits Sleep Number air-cooled beds perfectly
- Bamboo top wicks moisture and regulates heat
- Completely silent with a secure deep fit
The split review
- Some owners find it extremely hot to sleep on
- Extra corner fabric can bunch on some mattresses
The pick for: owners of air-cooled beds and anyone wanting a breathable bamboo surface.
Think twice if: you sleep hot and need guaranteed cooling from the cover itself.
5. Sealy Complete Waterproof Fitted Mattress Protector
A comfort knit top that stays cool for night sweaters, backed by a lifetime warranty.
Sealy’s approach starts with a soft, quiet poly knit top fabric backed by a waterproof layer. One self-described “furnace at night” owner reports the cover stays cool and has “no crinkle or crunch feel or noise” — a big win for hot sleepers. Its Clean Sleep treatment also fights odor-causing bacteria, keeping the cover fresher between washes.
The perfect grip sidewalls stretch to accommodate twin and full mattresses up to 15 inches deep, and queen and king mattresses up to 17 inches deep. Owners note it fits high-profile mattresses perfectly and stays put via deep pockets and stretchy sides. It’s machine washable warm with nonchlorine bleach when needed, and tumble dries on the lowest setting.
The catch is fit-dependent: it shines on high-profile mattresses but bunches on lower-profile beds with box springs. If you have a tall mattress or a new Sealy bed and sleep hot, this is a well-reviewed match — just check your bed height first.
What owners appreciate
- Comfort knit top stays cool for hot sleepers
- Fits tall mattresses up to 17 inches deep
- Backed by a Sealy Certified Lifetime Warranty
The fit note
- Bunches on lower-profile beds with box springs
- Can feel slightly slippery under loose sheets
Best suited to: hot sleepers on thick or high-profile mattresses who want a cool, quiet knit top.
pass on it if: your bed sits low and you don’t want excess fabric bunching.
6. Utopia Bedding Queen Mattress Protector Zippered 2 Pack
A zippered 6-sided encasement that fully wraps the mattress for total coverage.
This is the only zippered full encasement in the mid-range, and the huge owner base confirms why that matters. The wrap-around zipper seals the mattress completely on all 6 sides, so spills, sweat, and everyday accidents are blocked from every angle — not just the top. It fits queen mattresses up to 15 inches deep, and the stretchy knitted polyester slips on easily and stays put without shifting.
The non-crinkling design keeps it quiet and comfortable without feeling stiff, and owners with hotel industry experience validate the quality. It comes as a 2-pack, which is handy for guest beds or for swapping one while the other is in the wash. The smooth fabric lays flat across the mattress and stays unnoticeable under your sheets.
The honest split is on durability and water resistance: some owners mention water going through, and others find the material tears easily. The material is also a little thinner than some expect. If you want total zippered coverage and don’t mind treating it gently, the 2-pack value is strong.
Why it stands out
- Full 6-sided zippered encasement
- Comes as a 2-pack for swapping or guest beds
- Noiseless, non-crinkling knit polyester
The trade-offs
- Water resistance is mixed — some report leaks
- Material is thinner than expected and can tear
Reach for this if: you want total zippered coverage and the convenience of a 2-pack.
Look elsewhere if: you need a thick, heavy-duty fabric that shrugs off rough handling.
7. Treescend 100% Cotton Organic Mattress Protector
A GOTS-certified organic cotton pad with 0.25-inch padding for a quilted, cool sleep surface.
Treescend goes all-in on natural materials with 100% GOTS-certified organic cotton and an ultra-breathable 300 thread count long staple thread design. The 0.25-inch cotton padding adds a plush, quilted feel that balances protection and comfort — owners describe it as soft with just the right amount of padding and note it actually feels cool since it’s all cotton.
The snug 17-inch deep pocket stays tight and in place on thick mattresses and foam toppers. Reviewers praise the fine diamond stitching, thick elastic, and double/overcast seams as signs of a well-made pad. One owner sums it up as 100% cotton and “super plush,” noting it reduced sweating versus their old polyester cover. The absorbent top handles small spills and sweaty sleepers, and it’s machine washable.
The trade-off is clear: this is a water-resistant protector, not fully waterproof. Owners explicitly note it absorbs water rather than repelling it, so it’s not built for heavy accidents. If you want a chemical-free, breathable cotton pad for everyday protection and sleep comfort, this premium pick delivers.
What owners love
- 100% GOTS-certified organic cotton, no plastic feel
- Quilted 0.25-inch padding adds plush comfort
- Snug 17-inch deep pocket fits thick mattresses
The honest limit
- Water-resistant, not fully waterproof for heavy accidents
- Premium price for a non-waterproof pad
The pick for: cotton purists who want a chemical-free, breathable pad that feels plush.
Think twice if: you need a true waterproof barrier for kids or pets.
8. Bedgear Dri-Tec Waterproof Mattress Protector
A moisture-wicking performance cover that’s blocked wine and urine stains for years.
Bedgear’s Dri-Tec fabric is an advanced performance material that pulls moisture away from the body and disperses it for faster evaporation, keeping your sleep surface cool and dry. Its airflow-friendly build promotes ventilation without sacrificing waterproofing, ideal for hot sleepers. The fully banded elastic fits mattresses up to 18 inches deep with a fitted-sheet style grip.
The durability story is the standout here: customers note using this cover for 8+ years while blocking wine and urine stains completely, with no heat retention even on a 16.5-inch mattress. The quiet waterproof barrier shields against spills, sweat, and stains while maintaining a soft, noiseless surface. It’s also adjustable-base friendly and machine washable cold with a tumble dry on low.
The trade-off is price — some owners find it overpriced, and others note it’s cheaper at other retailers. If you want a performance-grade moisture-wicking layer that lasts for years and keeps hot sleepers cool, this is a worthy premium investment.
What makes it premium
- Dri-Tec fabric wicks moisture for faster evaporation
- Reviewers point out 8+ years of reliable use
- Fits thick mattresses up to 18 inches
The cost of performance
- Premium price — some owners find it overpriced
- Cheaper at other retailers
Best suited to: hot sleepers who want a long-lasting, moisture-wicking barrier on a deep mattress.
it’s not for you if: you’re on a tight budget and don’t need performance-grade wicking.
9. Naturepedic Organic Waterproof Mattress Protector Pad
A non-toxic organic cotton pad with a GOTS-approved waterproof layer and Drysleep technology.
Naturepedic builds this pad from two layers of organic cotton jersey with a GOTS-approved waterproof polyurethane layer. Its Drysleep barrier is an ultra-thin waterproof layer that blocks liquids while remaining breathable. It’s completely free of vinyl/PVC, phthalates, and latex, making it a strong choice for anyone avoiding harsh chemicals near their sleep surface.
The fitted sheet style has an organic cotton skirt with a full elastic perimeter stretching to cover mattress depths from 9 to 16 inches. Owners who replaced a Tempur-Pedic cover report this one fits perfectly with no chemical smell. After a toddler’s first big accident, one buyer found the mattress completely dry with no crinkle sound and soft material that’s machine wash and dryer friendly.
The honest caveats: it’s not 100% cotton despite the name — the outer fabric is organic cotton but the waterproof layer contains polyurethane, which one buyer flagged as misleading. There were also initial reports of leaks that were resolved with a free replacement. If you want a non-toxic, breathable waterproof barrier for a child’s bed, this delivers confidence at a premium price.
Why it’s special
- GOTS-approved organic cotton with non-toxic waterproof layer
- Drysleep barrier blocks liquids while breathing
- Free of vinyl/PVC, phthalates, and latex
The honest notes
- Contains polyurethane layer — not 100% cotton
- Initial batch had some leak reports
- Premium price
Reach for this if: you want a non-toxic, breathable waterproof barrier for a child’s or sensitive sleeper’s bed.
Look elsewhere if: you expect 100% cotton construction and don’t want any polyurethane layer.
Understanding the Specs
Waterproof Layer: TPU Thickness
The waterproof barrier is typically a TPU (thermoplastic polyurethane) film laminated to the fabric. Thicker TPU, like 0.02mm versus the market standard of 0.015mm, tends to hold up through more washes. Cheaper protectors can fail after around 20 washes, while thicker layers are built for 100 or more cleaning cycles. If durability matters, that tenth of a millimeter makes a real difference.
Coverage: Top-Only vs 5-Sided vs 6-Sided
Top-only protectors guard the sleeping surface but let liquids seep in around the edges. A 5-sided TPU encasement wraps the mattress top and all four sides. A zippered 6-sided encasement fully seals the entire mattress, including the bottom. For kids, pets, or long-term protection, more coverage means fewer surprises.
