Bed bugs are the nightmare that keeps you awake for all the wrong reasons. A full encasement cover is the only way to truly seal your mattress and box spring, trapping any pests inside and blocking new ones from getting in. The right pick is fully zippered, covers all six sides, and stands between you and a sleepless night.

Our Picks at a Glance
How To Choose The Best Bed Bug Mattress and Box Spring Covers
The biggest mistake is buying a simple fitted sheet-style protector. Those leave the sides and bottom of your mattress exposed, which is exactly where bed bugs hide. You need a full encasement that wraps the entire mattress in a zippered shell.
Check the Depth Measurement
Your mattress thickness determines which cover fits. A standard mattress is around 9 to 12 inches deep, but modern pillow-top and hybrid models can run up to 16 or even 20 inches. A cover that is too shallow won’t zip closed; one that is too deep leaves loose, baggy fabric that bunches under your sheets.
Look for the Waterproof Layer
Bed bug protection and waterproofing usually come together. A polyurethane inner lining stops spills, sweat, and accidents from soaking into the mattress, which also removes the moisture that can attract pests and cause mold. The trade-off is that waterproof layers can feel plasticky or noisy, so look for a soft outer fabric that masks the barrier underneath.

In‑Depth Reviews
1. Utopia Bedding Zippered Full Size (Pack of 2)
Our pick — over 4.5★ from 133,000+ verified ratings; the strongest balance of quality and price.
Two full encasements in one box, so you can armor a second bed without a second order.
You get a full 360° wrap that fits a 54 by 75 inch full mattress up to 13 inches deep, sealing every side. The stretchy knitted polyester slips on without fighting you and stays put, so it doesn’t shift and bunch overnight. It is a crowd favorite — a strong 4.6-star rating across more than 133,000 owners confirms this is the pick most people trust.
The waterproof layer blocks spills, sweat, and kid or pet accidents before they reach your mattress. What wins people over is the feel: “waterproof but soft, not plastic feeling or noisy like the plastic ones,” as owners put it. It washes in the machine and tumbles dry on low heat, which keeps the whole setup easy to maintain.
Compared to single-pack covers, the two-for-one format makes this the clear value leader — you protect a guest bed, a kid’s room, or a spare mattress for barely more than one premium cover costs. The material runs a little thinner than some expect, but that thinness is exactly what keeps it quiet and breathable under your sheets.
What Owners Rave About
- Completely noiseless — no crinkling under your sheets
- Secure zippered closure that won’t shift
- Soft knit fabric that feels smooth, not plasticky
Fair Trade-Offs
- Material is thinner than some premium rivals
- Only fits mattresses up to 13 inches deep
Grab this one if: you want maximum protection across two beds without paying double.
Think twice if: your mattress is deeper than 13 inches and needs a taller shell.
2. Four Seasons Essentials Full Size Zippered Cover
A Velcro flap over the zipper that locks the seal shut, so nothing sneaks through the track.
This six-sided encasement is built to fit any Full mattress 9 to 16 inches deep, giving you a wider range than most rivals. The standout detail is the Velcro zipper seal — after you zip it, the flap covers the pull and the track, closing off the one weak point where bed bugs could enter. Weighing only 2.5 pounds, it adds no bulk to your bed.
Spills and accidents pat dry easily because the polyurethane inner lining makes it fully waterproof, so your mattress underneath stays dry. Buyers report the fabric feels soft with a noticeable plastic lining, but it stays quiet and doesn’t trap heat. The zip comes pre-tied for confidence right out of the package.
The one honest catch is installation: you have to stand the mattress up to slide the cover over both sides, which is far easier with a second pair of hands. The full zipper wraps three sides, and the 3-inch secondary polyester lining around the seam adds durability where covers usually wear out first.
Built to last: the reinforced zipper seam is the most stressed part of any encasement, and this one gets extra support exactly there.
Plan for it: set aside a few minutes and grab a helper for the initial install — the payoff is a bug-proof seal.
3. Guardmax Premium Queen Box Spring Cover
The cover that finally gives your box spring the same protection you already give your mattress.
Most people armor the mattress and forget the box spring, which is just as vulnerable to moisture and pests. This zippered encasement fully covers all six sides of a Queen box spring, with a smooth-gliding, tight-locking zipper that keeps everything out. At a 4.7-star rating, it holds the highest score on this list.
The fabric is smooth, soft, and durable, backed by a waterproof inside layer that blocks humidity and spills. Owners say it “makes the box spring look nicer than just a bare box” and adds no noise to the bed. Fit is the thing everyone raves about — owners describe it going on like a glove, with some reporting it even blocks cats from clawing the underside.
This is a strong fit for humid climates where moisture collects inside the box spring and causes damage. Care is simple: machine wash cold with mild detergent and tumble dry, but never iron it — heat can damage the waterproof layer. If you need to move the bed, plan to remove the cover for transport.
What Wins People Over
- Smooth zipper that glides and locks tight
- Fits split king box springs, per owners
- Boosts the look of a bare box spring
Before You Buy
- Must be removed if you transport the bed
- Only covers the box spring, not the mattress
4. Mattressentials Zippered Queen Mattress Protector (14″-16″)
Built for thick mattresses, with a Velcro-covered zipper that seals the deal on all six sides.
If your Queen mattress runs 14 to 16 inches deep, standard covers won’t zip closed — this one is sized specifically for that taller profile. The six-sided encasement uses a full zipper that wraps around three sides, then covers the pull with Velcro so the track is fully sealed. Owners mention it fits 15-inch mattresses with ease and stays in place without shifting.
The 100% waterproof barrier blocks liquid and moisture, and the stretchy, breathable fabric stays soft and completely noiseless under your sheets. Reviews consistently praise the build quality, with several noting the zipper feels solid and the cover goes on quickly with no hassle. One owner even uses it to keep a mattress and foam topper held together as one unit.
It also carries a 3-year limited warranty covering defects in workmanship or materials, as long as you follow the care instructions. That kind of coverage is rare at this price point and signals the maker stands behind the stitching and zipper. For hot sleepers, owners mention no noticeable heat retention, which is a real plus for a waterproof cover.
Depth specialist: few covers in this range are built for 14-16 inch mattresses, so this fills a real gap.
Worth noting: one owner found it blocks sweat but doesn’t fully stop heavy liquid, so treat it as a strong barrier, not a pool liner.
5. SafeRest Premium Full Zippered Mattress Encasement
A lab-certified barrier with a soft cotton terry top that sleeps quiet and cool.
This encasement is explicitly lab-certified for bed bug, dust mite, and fluid protection, which is the gold standard for this category. Unlike fitted sheet-style protectors that leave sides exposed, this zippered cover gives you full 360° coverage. It fits mattresses up to 15 inches thick and weighs just 2.3 pounds, so it adds nothing heavy to your bed.
The top layer is a soft, noiseless cotton terry that owners say is unnoticeable under sheets — no crinkling, no heat feedback, no stiffness. Several reviews describe it as the piece that finally ended the bed bug cycle, especially when paired with diatomaceous earth around the bed. The strong stitch and zipper cover hold up for most, with the occasional report of a zipper that needs gentle handling.
The honest trade-off is that the terry top can absorb liquid before the waterproof layer catches it, so families with toddlers should pair it with a quick-dry pad on top. New units can also carry a chemical smell that fades after a low-heat wash. For anyone wanting certified protection over pure waterproofing, this is the one.
Why It Stands Out
- Lab-certified bed bug and dust mite proof
- Soft cotton terry top sleeps cool and quiet
- Fits mattresses up to 15 inches thick
What To Know
- Zipper can be delicate and may stick
- Terry top absorbs liquid before the waterproof layer
6. Four Seasons Essentials Queen Mattress Protector (16″-20″)
The deep-pocket specialist that swallows a 20-inch mattress and a topper without a fight.
Extra-thick mattresses and toppers are where most covers fail, and this one is built for that exact problem — it fits Queen mattresses 16 to 20 inches deep. Owners confirm it accommodates both a 13-inch mattress and a four-inch pad on top with room to spare. The six-sided design uses a full zipper that wraps around three sides, and a 3-inch secondary polyester lining reinforces the seam for long-term durability.
The polyurethane inner lining makes it 100% waterproof, blocking spills and moisture, while the stretchy outer fabric stays soft and completely noiseless. Reviews highlight the zipper running smoothly and zipping all the way around so sheets don’t slip off. With a 4.6-star average, the quality is consistently praised, and it carries a 3-year limited warranty against defects.
Installation on a heavy mattress is the main friction point — owners say reading the instructions first cuts the job from 15 minutes to just a few, and a second person helps with any mobility limitations. At 3 pounds, it’s a bit heavier than slimmer covers, which reflects the extra fabric for that deep fit.
Best for thick setups: if you run a tall mattress plus a topper, this is one of the few covers that genuinely fits.
Pro tip: read the included instructions before the first install and you’ll avoid the wasted 15 minutes others logged.
7. CleanRest PRO Presto! Zip-Off Top Mattress Encasement (Full)
The genius design that lets you unzip and wash the top in 45 seconds without lifting the mattress.
This is the only cover on the list built around easy washing — the top zips off and removes in 45 seconds by one person, no mattress lifting required. That means you can actually wash the sleeping surface regularly, which is the whole point of a hypoallergenic barrier. It fits Full mattresses 53 by 75 inches, 9 to 18 inches deep, and extra zip-off tops are available for laundry rotation.
The MicronOne fabric blocks bed bugs, dust mites, and allergens without harsh chemicals, and the Zip-N-Click 2X locking zipper delivers full 360° encasement closure. It’s 100% waterproof while staying breathable and noiseless, and it’s hot-water washable — a detail that matters for hygiene. A 10-year warranty backs the oversized zipper and tear-resistant stretch fabric with reinforced double stitching.
The catch is the initial install: on a heavy mattress, owners recommend a helper for the first setup, though solo removal and reinstall of the top afterward is easy. This is the premium pick for anyone who hates wrestling a full encasement into the wash — the zip-off top changes the whole maintenance routine.
Why It’s Different
- Zip-off top washes in seconds, no lifting
- 10-year warranty on zipper and stitching
- Hot-water washable for deep hygiene
Keep In Mind
- Initial install on heavy mattresses needs a helper
- Zipper cover can be a bit tricky at first
8. Mission: Allergy Premium Microfiber Mattress Encasing (Queen, 12″)
The medical-grade encasing designed by a board-certified allergist and recommended by allergy departments.
Allergy specialists and university allergy departments recommend this brand. It’s medical grade, blocks 100% of dust mite and animal dander allergens, is third-party tested by Indoor Biotechnologies, Inc., and is certified bedbug-proof. Designed by a board-certified allergist, it’s specifically recommended by leading allergy specialists and university allergy departments.
The silky soft, tightly woven 100% microfiber polyester is breathable and water vapor-permeable, so it doesn’t feel like plastic under your sheets. Customers note fewer sinus headaches and more restful sleep. The fabric has a quality sateen feel, fits deep mattresses easily, and slides on without being slippery.
This is the most premium-priced pick on the list, and the value for money gets mixed reviews — it’s expensive, but owners consistently say it’s worth it for allergy-free sleep. The sewing is top-tier with bound seams, an interior zipper flap, and an extra-long zipper for easy placement, all backed by a lifetime warranty and made in the USA. If dust mites are your enemy, this is the definitive answer.
Allergy heavy-hitter: the 100% allergen block claim, third-party testing, and allergist design put this in a class of its own.
Budget reality check: it’s the costliest cover here, so reserve it for households where allergen relief is the priority, not just pest defense.
Understanding the Specs
Six-Sided Encasement vs. Fitted Sheet
A true encasement wraps the top, bottom, and all four sides of your mattress in a zippered shell. A fitted sheet-style protector only covers the top and leaves the sides exposed — exactly where bed bugs settle. Always look for the word “encasement” and a full-wrap zipper, not just a stretchy skirt.
Waterproof vs. Water Repellent
A 100% waterproof cover has a sealed barrier, usually polyurethane, that stops liquid from soaking through. Water repellent means the fabric beads up liquid but can eventually absorb it under pressure. If you have kids, pets, or worry about spills, choose the fully waterproof construction with the inner lining.
