If you’re dealing with bed bugs (or just trying not to), the mattress cover you pick actually matters a lot. You want a full six-sided encasement, a bed-bug-proof zipper, quiet fabric that doesn’t sleep hot, and the right depth so it actually fits your mattress. Good covers help trap any bugs inside and block new ones from moving in, but they only work if they’re designed properly.
Top picks
Protect-A-Bed Essential Zippered Mattress Encasement (Queen, fits 6–11″) — Best overall for most people
A fully enclosed, six-sided encasement from one of the best-known names in bed bug bedding, with a waterproof top, dust-mite barrier, and quiet, breathable fabric.
Why it wins: Protect-A-Bed pairs a reputable, widely-recommended brand with a tight zippered six-sided barrier, antimicrobial treatment, and a smooth, quiet top, making it an easy “set it and forget it” pick for most standard-depth US mattresses.
Pros
- Full 6-sided encasement with zippered closure
- 100% waterproof top plus dust-mite barrier
- Breathable, quiet fabric that stays comfortable
- Antimicrobial treatment from a trusted encasement brand
Cons
- Sized for standard 6–11″ mattresses, so measure a thick/pillow-top bed first
- Premium branding costs a little more than no-name covers
- Smooth top has a slight “membrane” feel vs. a bare mattress
Social proof
Protect-A-Bed’s encasements are frequently cited in public-health and pest-control guidance as meeting the key design features of a real bed bug encasement, and this Essential model shows strong, consistent buyer feedback on Amazon. See reviews on Amazon for current sentiment and fit notes.
Trade-offs / Who should skip
Choose something else if your mattress is very deep or you’re stacking toppers (see the Four Seasons deep-pocket pick below), or if you want the absolute cheapest cover for a dorm or guest bed. Otherwise, this is a very solid default for most homes, rentals, and guest rooms.

Four Seasons Essentials Super Deep Pocket Encasement (Queen, 20–24″) — Best for very deep & thick mattresses
A zippered, bed-bug-proof, waterproof encasement built specifically for very tall mattresses in the 20–24″ range, where most standard covers simply won’t reach.
Why it wins: If you’ve got a thick hybrid, a pillow-top, or a mattress-plus-topper stack, this cover’s extra-deep 20–24″ pocket and full zippered six-sided design mean you actually get a proper seal instead of a cover that pops off the corners.
Pros
- Extra-deep 20–24″ pocket for very tall mattresses
- Zippered six-sided encasement with bed bug & waterproof protection
- One of the highest review counts in its category
- Fits thick hybrids and topper stacks other covers can’t
Cons
- Overkill (and loose) on a slim 8–10″ mattress — match the depth to your bed
- Big encasement can be a workout to install on a heavy bed
- Polyester top is a touch warmer than a cotton knit
Social proof
With well over 800 ratings, this Four Seasons encasement is one of the most-reviewed deep-pocket options available, and buyers consistently call out the genuine deep fit and reliable waterproofing. See reviews on Amazon for up-to-date ratings and photos.
Trade-offs / Who should skip
Skip this if your mattress is standard depth — you’ll get a baggier fit than you need, and the Protect-A-Bed or Hospitology covers will sit tighter. But for genuinely deep beds, this is the one that actually fits.

Hospitology Products Sleep Defense System (Queen, 12″ standard) — Best for cool, quiet protection
A hotel-style polyester knit encasement that’s lab-tested, waterproof, and surprisingly cool to sleep on.
Why it wins: If you’re worried about heat and fabric noise, this smooth knit encasement gives lab-tested six-sided protection while staying breathable and soft.
Pros
- Lab-tested waterproof barrier on all six sides
- Extra-soft knit polyester that doesn’t crinkle much
- Breathable membrane to limit heat build-up
- 5-year limited manufacturer warranty
Cons
- Standard depth; very tall mattresses need a different size
- Polyester feel, not everyone’s favorite texture
- Zipper is good, but flap is less beefy than premium bed-bug models
Social proof
Hospitology’s Sleep Defense System comes from a brand that focuses on “barrier bedding” for healthcare and hospitality, and the encasement is widely sold through large retailers with consistently positive feedback on comfort and quietness. See reviews on Amazon for current user impressions.
Trade-offs / Who should skip
If you’re dealing with a very heavy, deep mattress and want the tightest deep-pocket fit, you might gravitate to the Protect-A-Bed Essential or the Four Seasons deep-pocket cover above. But if noise and warmth are your main worries, Hospitology is a very nice balance.

Home Signature 6-Sided Zippered Encasement (Queen, 12″) — Best for allergies + bed bug protection
A fully enclosed six-sided encasement marketed as both bed-bug and dust-mite proof, which is exactly the combination allergy-prone sleepers want in a barrier cover.
No products found.
Why it wins: Home Signature seals all six sides behind a zipper and is specifically rated bed-bug and dust-mite proof, so it blocks the allergens (dust-mite waste, dander) that collect in a mattress along with the bugs — at a mid-range price.
Pros
- Six-sided zippered encasement, bed-bug and dust-mite proof
- Waterproof barrier that also blocks common mattress allergens
- 12″ depth suits most standard mattresses
- Reasonable mid-range price for a full encasement
Cons
- Mixed owner feedback — build feels lighter than premium brands
- Polyester top runs a little warm in hot rooms
- Check your depth; 12″ pocket is snug on very thick beds
Social proof
Home Signature’s encasement carries triple-digit ratings with an explicit dust-mite and bed-bug proof claim, which is why it lands in the allergy-focused slot. Feedback is more mixed than the premium picks, so see reviews on Amazon to confirm current fit and quality before buying.
Trade-offs / Who should skip
If allergy protection is critical and you want the most consistent quality, the Protect-A-Bed Essential up top carries the same dust-mite barrier with stronger reviews. But if you specifically want a dust-mite + bed-bug cover at a lower price, this is a sensible middle option.

QATAN 6-Sided Zippered Mattress Encasement (Queen) — Best budget-friendly full encasement
A no-frills six-sided zippered encasement that nails the basics — full seal, waterproofing, quiet fabric — at one of the lowest prices for a genuine encasement.
Why it wins: QATAN gives you a real six-sided zippered encasement (not a partial fitted cover) with waterproof, noiseless fabric for the price of a basic protector, which makes it great for kids’ rooms, dorms, or outfitting several beds at once.
Pros
- Six-sided, fully zippered encasement for complete coverage
- Waterproof and noiseless top fabric
- Machine washable and easy to live with
- Among the lowest prices for a true encasement, with solid ratings
Cons
- Zipper and seams feel lighter than premium bed-bug brands
- Polyester is a bit warmer than cotton or bamboo
- Fewer depth options than the specialist covers
Social proof
QATAN’s encasement holds a strong rating across triple-digit reviews, with buyers regularly praising the true full-seal fit and quiet fabric for the money. See reviews on Amazon to check how it’s holding up for recent buyers.
Trade-offs / Who should skip
If you’re dealing with a severe infestation and want the beefiest zipper flap and thickest fabric, lean toward the Protect-A-Bed Essential or Four Seasons deep-pocket cover first. But for covering kids’ beds, dorms, or a guest room on a tighter budget, QATAN is a very reasonable compromise.
Scores: Performance 4/5 · Bed bug security 4/5 · Ease of Use 4/5 · Value 4.5/5
Quick compare
- Protect-A-Bed Essential Encasement — Best for most people: Trusted brand, six-sided zippered seal, waterproof + dust-mite barrier; sized for standard 6–11″ mattresses.
- Four Seasons Super Deep Pocket Encasement — Best for very deep & thick mattresses: Genuine 20–24″ pocket and full zippered seal; too baggy for a slim standard bed.
- Hospitology Sleep Defense System — Best for cool, quiet protection: Soft knit, breathable membrane; standard depth means very tall mattresses may need another model.
- Home Signature 6-Sided Encasement — Best for allergies + bed bugs: Dust-mite and bed-bug proof at a mid-range price; feedback is more mixed than the premium picks.
- QATAN 6-Sided Encasement — Best budget full encasement: True six-sided waterproof protection at a low price; lighter zipper and slightly warmer fabric.
(If your mattress is 12 inches or less and you want a very thin, budget-friendly encasement, the Linenspa Zippered Waterproof Mattress Encasement also performs well for basic bed bug protection, but its limited depth makes it less ideal for thicker modern mattresses.)
FAQs
Q: Will a bed bug mattress cover get rid of an infestation by itself?
A: Not by itself. A proper encasement traps bugs already in the mattress and stops new ones from living there, which cuts down on bites from that area. But bed bugs can also hide in headboards, baseboards, nightstands, and other furniture, so you usually still need a full treatment plan (often with a licensed pest-control pro).
Q: Do I need to encase both the mattress and the box spring?
A: It’s strongly recommended. Box springs are classic hiding spots, and many public-health and pest-control sources treat the mattress and box spring as a single “sleep system” that should be fully sealed to remove those hiding places. Many brands (Protect-A-Bed, Linenspa, Hospitology) sell matching box-spring encasements, so look for a bundle if you have a traditional bed setup.
Q: How often should I wash an encasement?
A: Follow the manufacturer’s instructions, but most recommend only washing when needed and using gentle cycles to protect the waterproof membrane and seams. Over-washing or using very high heat can wear out the coating faster. Sheets and mattress pads can be washed weekly; the encasement is more of a long-term barrier you disturb as little as possible.
Q: What should I avoid when shopping for a bed bug cover?
A:
- Avoid partial covers (only top and sides) if bed bugs are your concern.
- Be cautious with chemically treated covers that rely on pesticides; they don’t usually work well for control and add unnecessary insecticide exposure.
- Skip anything with large, exposed zipper teeth or no zipper end cover—those gaps can let bugs slip through.
