A fitted pad covers only the top, leaving the sides and bottom of the mattress bare. A zippered encasement wraps the whole mattress like a sealed envelope — top, sides, and bottom — so bed bugs and spills never reach the foam inside.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Below you will find eight zippered encasements, sorted by how well each one seals, how deep it fits, and how it handles liquid in daily life. Whether you are covering a dorm-room twin or a king pillow-top, the right bed bug mattress and waterproof protector depends on depth, closure, and fabric.
Our Picks at a Glance
How To Choose The Best Bed Bug Mattress and Waterproof Protector
A mattress encasement is a sealed fabric bag for your mattress, and it lives or dies on three things: depth, closure, and backing. Get the depth wrong and the zipper strains or the fabric sags. Get the closure wrong and bed bugs walk in through a gap. Get the backing wrong and a nighttime accident reaches the foam. Here is what actually matters before you buy.
Measure Your Mattress Depth First
The single most common mistake is guessing your mattress height instead of measuring it. Measure from the top of the mattress down to where it meets the box spring, then add the height of any topper you use. If your mattress plus topper tops out at 12 inches, a cover rated for 6 to 9 inches will not close. A cover rated up to 15 inches will. When in doubt, buy the deeper size — the stretchy side panels take up a little slack, but they cannot stretch to cover three extra inches.
Zipper Quality and the Velcro Seal
The zipper is the only opening in the whole barrier, so it is the one place a bed bug can enter. Look for a zipper that runs around at least three sides of the mattress, which lets you lay the cover flat and slide the mattress in rather than wrestling it through a tight hole. Some covers add a Velcro tab over the zipper pull once it is closed, and that small flap covers the one remaining gap. A zipper with no end guard leaves a tiny slit at the corner.
Waterproof Backing, Not Just Water-Resistant Top
Waterproof and water-resistant are not the same thing. A water-resistant top fabric beads liquid for a few seconds before it soaks in. A waterproof encasement has a polyurethane backing or a TPU layer bonded to the fabric, which blocks liquid from passing through at all. If the spills are pet accidents, bed-wetting, or caregiving accidents, you want the backed version every time. This is also why you can machine wash most of these covers — the backing survives the cycle.
Fabric Feel and Noise
Older vinyl covers sounded like a chip bag every time you rolled over. Modern encasements use knitted polyester or a cotton terry top over the backing, which keeps the cover quiet under a fitted sheet. A brushed polyester or terry surface also keeps your sheets from sliding around. If quiet sleep is your priority, skip anything described as plastic or vinyl and choose a knit or terry top instead.

In‑Depth Reviews
1. Utopia Bedding Waterproof Mattress Protector Queen Size, Zippered Mattress Encasement
Our pick — over 4.5★ from 133,500+ verified ratings; the strongest balance of quality and price.
The best-selling six-sided seal that swallows a queen mattress plus a topper whole.
If your queen mattress and its topper stack up thicker than you think, this is the encasement to start with. It fits 60 by 80 inch queen mattresses up to 15 inches deep, and it wraps all six sides rather than sitting on top like a fitted sheet. That depth rating is the headline number here, because the Full Zippered pick lower down maxes out at 6 to 9 inches — a 15-inch ceiling versus a 9-inch one is a real gap when you have a pillow-top. A high proportion of owners — the crowd favorite at 4.6 stars across 133,000+ ratings — describe slipping it over the mattress, zipping the wrap-around closure, and having it stay put without shifting.
What wins people over is how the fabric behaves once it is on. The knitted polyester top is smooth and non-crinkling, so it stays quiet under sheets instead of crackling every time you turn. The TPU backing — a thin waterproof layer bonded to the fabric — sits on all sides, so spilled coffee gets repelled and wiped off rather than soaking into foam. The zipper is the other consistent point of praise: it seals completely shut, which is the one gap where bed bugs could otherwise walk in. Owners also lean on the machine-wash cycle, running hot-water washes after a wet night and air-drying the cover back to life.
The catch worth knowing: not every unit lives up to the waterproof claim, and a few buyers report water pushing through over long exposure. There is also a mild split on durability, with a small share finding the cover tears under heavy use. Neither trend applies to most owners, but if your main worry is heavy long-term liquid exposure rather than bed bugs, size up carefully and treat the fabric gently. The material is also on the thinner side, so it protects the surface without adding cushioning.
Where it seals the deal
- Wraps a queen mattress up to 15 inches deep on all six sides, plus toppers
- TPU backing on all sides helps keep spills and accidents out of the foam
- Sturdy wrap-around zipper stays closed and keeps the cover from sliding around
- Knitted polyester top is quiet with no crinkle under the sheets
What to know first
- Some owners mention liquid eventually seeping through on heavy saturation
- Material runs thin, so it protects the surface without adding softness
- A small share of customers note tearing with rough daily use
- Packaging and finish may vary slightly from unit to unit
Best for: a standard-depth queen with a topper you want sealed top, sides, and bottom.
Skip if: you need a very deep pillow-top fit — the Mattressentials pick goes to 16 inches.
2. Full Zippered Mattress Protector, Waterproof, 6-9 Inch
The cheapest full-coverage seal here — and the one that fits thin mattresses best.
A thin mattress is a real problem for most encasements, because the fabric has to be pulled tight or it sags into wrinkles. This one sidesteps that by being designed for mattresses 6 to 9 inches deep, which covers hospital beds, RV beds, kids’ bunks, and thin foam mattresses that thicker covers bunch up on. The spunlace non-woven fabric feels light and thin, and it adds no bulk to the sleep surface. Owners describe it as quiet — no crunch, no plastic rustle — and the six-sided zipper runs all the way around, so nothing is left exposed like on a fitted pad.
What the review pages keep coming back to is how the cover handles daily mess: reviewers point out wet and muddy dog feet, slobber, and everyday spills wiped clean, and several say it held up through repeated machine washes with no leaks. A few owners treat the install as a two-person job — the method is a slide-on-and-zip, like putting a pillowcase on a very heavy pillow, so having a second set of hands makes it easier, though a solo install is doable. Owners size it for exactly what it is built for: protecting guest room and rental mattresses against bugs, stains, and wear without spending much.
Here is the honest trade-off: despite the “waterproof” name, a handful of shoppers say the cover failing under sustained daily liquid exposure, so it is not the pick for incontinence care or any heavy repeat-wetting situation. The non-woven fabric is also the least cushioned in this lineup — it protects the mattress, it does not soften it. For a low-traffic guest bed or a bed that needs bug and stain coverage on a budget, it does its job; for daily caregiving, size up to a backed option.
The non-woven reality: spunlace non-woven is the lightest fabric here. It keeps the cover silent and packable for RVs and guest rooms, but it cannot fake the plush feel of a knit or terry top.
Where it lands: pick this when the mattress is 6 to 9 inches thick and the job is bug and spill sealing, not nightly liquid handling.
Reach for this if you need a full zippered seal on a thin mattress and want to keep the spend small.
Look elsewhere if the mattress is thicker than 9 inches or the bed sees daily wet accidents.
3. Amazon Basics Zippered Mattress Encasement – Waterproof, Queen
A simple, quiet 360-degree seal that turns a stained dorm mattress back into a clean one.
For a queen mattress that measures at standard depth, this is the most straightforward install in the whole lineup. The 360-degree zipper wraps the mattress completely and, as owners describe it, the zip runs far enough down that the cover slides over the corners instead of needing to be wrestled on. Over a third of owners specifically call out the fit, and the second-most-discussed point is how easy it is to get the cover on. College dorm beds, guest rooms, and standard 12-inch queens all sit comfortably inside the 30cm (12-inch) pocket depth.
The fabric blend is where the comfort comes from. Polyester with a polyurethane backing gives breathable, noise-free coverage, and owners consistently note that it does not feel stiff or crinkly under sheets. The backing is what makes it waterproof, and it survives washing, so a stained mattress stays covered wash after wash. Owners also like how a worn, discolored mattress instantly looks tidy again once the cover is zipped on, which is the practical reason this pick sells for guest rooms and rentals.
Two things to weigh. First, the zipper and water-resistance feedback lands mixed rather than glowing — most owners are fine with both, but a few do note the zipper feeling less smooth over time, and a handful of water-resistance complaints appear. Second, this pick is built around a 12-inch pocket depth, so it will not stretch to a deep pillow-top. There are no printed orientation instructions with the unit, so plan the install before you start — a couple of extra minutes of maneuvering beats guessing which way the zip runs.
Why it earns its place
- 360-degree zipper wraps the whole mattress and slips on easily
- Polyurethane backing goes fully waterproof while staying breathable and quiet
- Machine washable and dryer friendly, holding up through cycles
- Made with 71% Global Recycled Standard (GRS) certified recycled post-consumer polyester
What to watch for
- 12-inch pocket depth will not fit a deep pillow-top mattress
- No printed orientation instructions, so first-time installs take planning
- Zipper smoothness lands as a mixed point rather than universal praise
- A small set of buyers report water-resistance falling short of expectation
Pick this one for fast, fuss-free sealing on a standard-depth queen — dorm beds, spare rooms, and rentals especially.
skip it if your mattress runs past 12 inches or you need printed setup guidance in the box.
4. Utopia Bedding Waterproof Zippered Mattress Protector Queen Size, 10″ Deep Pocket
The silky knitted cover that owners happily sleep on with no bed pad underneath.
Most encasements are designed to hide under a sheet, but this one gets described by owners as soft enough to sleep straight on. That depends on the fabric: a smooth knitted polyester that feels silky rather than plastic-y, with a quiet finish that makes no noise when you move. The 60 by 80 inch queen fit with a 10 inch deep pocket holds the cover snug without slack, and the six-sided zippered closure seals the whole mattress so bed bugs and dust mites have nowhere to enter. Fit and softness are the two things owners talk about most, and both land positive here.
The closing details are what keep it usable long term. The zipper runs smoothly and has an end flap that keeps the pull from catching or opening on its own. The material is sturdy without being stiff or crinkly, so it does not change how the mattress feels to lie on. Owners also tell an interesting sizing tip from their own experience: buying one size up, such as a 12-inch cover for a 10-inch mattress, makes the install far easier — one owner who did exactly that said sizing down to the 10-inch version would have meant a real struggle getting it on. That is worth remembering if your mattress sits right at the limit.
The honest split is on water resistance. Many owners mention it genuinely repels liquid, but a smaller set say moisture eventually soaks through, so it is not a guarantee against repeated heavy wetting. It is also a standard-depth cover — 10 inches, with a comfortable stretch — so a very deep mattress plus topper will strain the zipper. For a normal queen where the goal is sealing plus a comfortable, quiet surface, this is a strong middle pick.
Why owners sleep on it bare: the knitted finish is the softest-feeling cover in this lineup and holds up through the wash without going stiff.
The sizing trick: many owners recommend ordering one depth size up for easy install — especially if your mattress is borderline.
Ideal if you want a cover soft and quiet enough to skip the bed pad entirely.
Consider the deeper picks if you’re covering a very thick mattress or need certainty on heavy wet spills.
5. Linenspa Encasement Waterproof Mattress Protector — Zippered 360°, Full
The budget-priced full encasement with a warranty that punches well above its tier.
What separates this cover from the others is what happens if it ever fails: it carries a 10-year limited warranty against manufacturer’s defects. That backing matters for a full-size mattress headed to a dorm or a rental, where the cover is going to live a hard life. The encasement slides on like an envelope rather than a fitted sheet, zips closed on all sides, and covers the top, sides, and bottom so nothing is left bare. Fit runs standard mattresses up to 12 inches thick.
Owners describe it as genuinely waterproof in the moments that count: wet accidents get contained, and the surface wipes clean rather than soaking in. It runs quiet all night with no crinkle, and it does not alter how the mattress feels — which is the thing that keeps people from noticing it is there. The brushed polyester surface feels soft under a sheet, and owners find it easy to install without wrestling. Quality is the one thing owners agree on most here, and installation is a close second.
Two caveats worth flagging honestly. The zipper is durable but not completely noiseless — owners say you can still hear the fabric when you roll, even with a fitted sheet over it. And the waterproof backing holds for most spills but a few customers note leaks under sustained saturation, so it is not built for heavy daily wetting. If a quiet night is your priority and you want a safety net in the form of a warranty, this one is tough to top for a budget bed.
What earns the trust
- 10-year limited warranty stands behind the encasement
- 360-degree zipper seals top, sides, and bottom of the mattress
- Waterproof lining contains real spills and wipes clean
- Brushed polyester surface stays quiet under a fitted sheet
Where it stops short
- Zipper and fabric are audible when you move on the bed
- Some reviewers point out leaks under repeated heavy wetting
- Fits up to 12 inches only — deep mattress owners need another pick
- Durability feedback is mixed, with a small share reporting tears
The pick for: a dorm, guest, or rental full-size mattress where you want the warranty safety net.
Not the one if: your mattress is thicker than 12 inches or you need total silence when you roll over.
6. Mattressentials Zippered Queen Mattress Protector (14″-16″ Depth)
The deep-fit seal for pillow-top queens that push past the standard depth limit.
If your queen mattress measures 14 to 16 inches thick, most of the covers here will not stretch over it — this one is designed for exactly that. It wraps all six sides and, once closed, adds a Velcro zipper seal over the top of the zipper so the pull cannot creep open and nothing slips through that final gap. Owners describe it as the tightest fit of the covers they tried, but still easy enough to install solo on a thick mattress, even a 16-inch queen — with the slack running just slightly loose rather than fighting the corners.
The fabric is described by owners as not feeling like plastic, which is what you want when the point is to forget the cover is there. Water resistance and material quality both land on the positive side, and the cover is built to handle pets and kids without letting liquids soak in. The zipper quality and the Velcro cover earn the most specific praise and the fit and easy install are the aspects owners bring up most often — the two things that decide whether a deep cover is worth keeping.
One honest note: it runs on the pricier side of this lineup, and the waterproofing is not independently verified by every owner — so treat it as a strong daily barrier rather than an unbreakable one. It will also not fit a standard 10-inch mattress snugly, so if your mattress is short, look at the standard-depth Utopia picks instead. For a genuine pillow-top queen, this is the one that actually closes.
Why the depth rating matters: 14 to 16 inches covers the pillow-top mattresses other covers simply cannot reach, so the zipper closes instead of straining.
The one trade-off: it costs more than the standard-depth covers, so it makes sense for a truly deep bed and little else.
Get this if your mattress runs 14 to 16 inches and the other covers leave the sides exposed.
Steer clear if your mattress is standard depth — it will fit too loosely, and you’ll want the tighter standard picks.
7. Four Seasons Essentials Cotton Terry Zippered Encasement, Queen
The cotton terry top that feels like a mattress pad and seals like an encasement.
Cotton terry on top is the difference here — the surface feels like a towel, not a plastic sheet, and owners consistently describe it as soft, well-made, and quiet with no crinkle. It fits 12 to 16 inch thick queen mattresses, so it covers the deep pillow-tops as well as standard queens, and the full zipper wraps around three sides, meaning the mattress slides in through the open end and zips shut in place. Owners note that fitting a king can take a second set of hands, but a queen install is manageable on your own.
Two details owners raise. First, washing and drying work well, and owners like that the cover survives cycles and preserves the mattress feel. Second, the backing on the underside is plastic or PVC, so the top and sides are the breathable cotton terry while the bottom carries the waterproof layer — which means the cover really does block liquid, but the bottom is stiffer than the top and needs to be kept away from rough box-spring edges. Owners who fit a 12-inch mattress snugly get the best result; the stretch handles standard depth comfortably.
The honest caveat: the zipper quality is mixed — most owners find it strong, but a minority report bad zippers, so it is worth inspecting the zip on arrival. It also carries a 3-year limited warranty, which is shorter than the Linenspa pick’s 10 years. For a queen where you want a cotton-feel top over full six-sided protection, this is the softest option that still seals.
Why owners keep it
- Cotton terry surface feels soft and quiet rather than plasticky
- Full zipper runs around three sides for easy slide-on install
- 100% waterproof backing keeps the mattress surface dry
- Fits queen mattresses from 12 to 16 inches thick
Worth knowing
- Zipper quality is mixed — a minority report bad zippers
- Bottom backing is plastic/PVC and can be stiff against rough springs
- 3-year limited warranty is shorter than some rivals
- King-size installs go better with two people
The best pick for a queen where you want a soft cotton-feel top and don’t want to compromise on a full six-sided seal.
Not the case if you want the longest warranty — the Linenspa covers 10 years, versus the 3 years here.
8. Slumberfy King Size Waterproof Bamboo Mattress Encasement, Zippered Bed Bug Protector
The king-size encasement whose top zips off so you never wrestle a whole mattress to wash it.
Washing a king encasement usually means pulling off the entire cover, which is the exact chore that keeps people from washing it at all. This one solves that with a 360-degree EZ zipper that runs around the entire top edge, so the top layer can be unzipped and taken off by itself for the machine — the bottom stays fitted like a sheet. Owners describe it as easy to put on and remove, and one reports a solo install under 10 minutes even with a 12-inch mattress and a topper. The fabric is 60% bamboo viscose with a polyester bottom layer, and it stays silent with none of the crinkle you get from a plastic protector.
The bamboo viscose top is what owners like to touch — soft, skin-safe, and quiet, with no sweating underneath. The cover is sealed on all six sides with a zipper overlap, so it blocks bed bugs and dust mites as well as liquid. The waterproof layer holds up in everyday spills; the review pages note everything from pet accidents to spilled drinks being contained with no soak-through. The 280 thread count gives the surface a fine, smooth feel that keeps sheets from snagging. It is also machine washable, and owners keep using it over multiple wash cycles.
The trade-off: water resistance divides owners more here than on any other pick in this lineup — a minority find it does not hold up when liquid sits for a while, so treat it as a barrier for ordinary accidents, not for sustained wetting. It is also double the price of the budget picks, though a lifetime warranty backs the purchase. And on a 6-to-9-inch mattress, some find it fits a little loose at the corners.
The one-of-a-kind feature: the 360-degree zip-off top turns a two-person king-bed chore into a one-person job, which is why owners keep recommending it for beds where washing has to be easy.
What to expect: bamboo viscose means a soft, quiet, breathable surface — paired with a waterproofing that handles spills but not prolonged standing liquid.
Best suited to a king bed where easing the washing routine matters more than anything else.
Better skip if you need the waterproof layer to survive heavy, repeat wetting — the standard-depth Utopia covers do that with less fuss.
Understanding the Specs
Depth Fit (Pocket Depth)
The listed depth on every one of these covers is the maximum mattress height it can wrap around and still close cleanly. A cover listed for 6 to 9 inches is built for a thin mattress and will bunch up on a standard one; a cover rated 14 to 16 inches is built for a pillow-top and will feel loose on a 10-inch queen. Match the depth to your mattress plus any topper you use, and where the mattress sits right at the limit, sizing up one notch usually beats sizing exact. Many owners find the stretchy side panels forgive a little slack, but they cannot make up three missing inches.
Zipper and Seal Type
The zipper is the only opening in the barrier, so its quality decides whether bed bugs can get in. A wrap-around or 360-degree zipper travels around three sides of the mattress, letting you lay the cover flat and slide the mattress in — far easier than feeding it through a tight hole. Some covers add a Velcro tab that covers the zipper pull once closed, which closes off the last possible entry spot, while a cover without that tab leaves a tiny gap. Look for a cover whose zipper overlaps or seals rather than simply stopping.

Final Thoughts: The Verdict
For most beds, the bed bug mattress and waterproof protector winner is the Utopia Bedding Queen Zippered Encasement, because it wraps a queen up to 15 inches deep on all six sides, uses a TPU backing on every side, and stays quiet under the sheets — and it is the crowd favorite with the deep review history to prove it. If your mattress is a thick pillow-top running 14 to 16 inches, grab the Mattressentials Zippered Queen Protector, which closes where the standard covers cannot. And for a thin mattress, a guest bed, or an RV bunk on a tight budget, the Full Zippered Mattress Protector gets the seal done for less. Whatever you pick, match the depth to your mattress before you buy — that one measurement decides whether the zipper closes cleanly, and getting it right is the difference between a protector you keep for years and one you stop using by spring.
