Our Picks: Best All In One Bed Zippered Mattress Cover With Bug Blocker reviews
1. Bed Bug Blocker All-in-One Mattress Protector for Queen Beds
This Queen-size Bed Bug Blocker is a full mattress encasement, rather than a pad that covers only the sleeping surface. Its water- and stain-resistant material is designed to help shield the mattress from everyday spills and irritants. An interior barrier flap, hook-and-loop closure, and zipper make up the listed triple-seal system.
The cover is made with a soft nonwoven blend and polyurethane, and it is OEKO-TEX Standard 100 certified according to the supplied product information. The full enclosure can be useful if you want coverage underneath the mattress as well as on top. Some owners find it straightforward to put on, while others note that a tight fit can make installation harder—especially with a thick mattress. A second person may help.
One practical point: the supplied details describe a protective barrier, but do not specify a bed-bug certification or guarantee. If bed-bug exclusion is your main concern, check the product listing and care instructions for the exact protection claims before buying. The zipper should be pulled carefully so it does not catch on the protective guard.
Pros:
- Full zippered coverage on all sides
- Triple-seal closure includes a flap and hook-and-loop fastener
- Water- and stain-resistant design
- Machine washable, with no-heat tumble drying listed
Cons:
- A tight fit may make installation a two-person job
- Mattress depth details are not included in the supplied Queen-size information
Verdict: Choose this model if you want a Queen-size, six-sided cover with a layered zipper closure, but confirm the fit and specific pest-protection claims before ordering.
2. Bed Bug Blocker All-in-One Encasement for California King Beds
This version is listed for a California King mattress and provides six-sided coverage. The supplied dimensions are 72 by 84 inches with a 15-inch depth. Its water-resistant layer is intended to help protect against spills and stains, while the product description also identifies a breathable, quiet fabric design and a barrier intended to block dust-mite allergens.
The zipper closure and sealed construction make this a more complete option than a standard fitted protector. The listing describes an ultrasonic seal and a layered fabric construction, but does not provide a specific bed-bug certification or guarantee. For pest concerns, verify the manufacturer’s exact claim rather than relying on the product name alone.
As with the other Bed Bug Blocker sizes, a snug fit may take patience. Owners have found that easing the zipper past its protective guard helps prevent snagging, and a second person can make fitting a large encasement easier. The care instructions call for a warm machine wash and tumble drying with no heat.
Pros:
- Listed California King dimensions include a 15-inch depth
- Six-sided coverage with a water-resistant layer
- Designed to help block dust-mite allergens
- Machine washable according to the supplied care instructions
Cons:
- May be challenging to fit on a thick or tightly sized mattress
- Specific bed-bug certification is not stated in the supplied details
Verdict: This is the clearest fit-specific pick for a California King mattress when you want a water-resistant, fully enclosed design; measure your mattress before ordering.
3. Bed Bug Blocker Triple-Seal Mattress Protector for King Beds
This King-size Bed Bug Blocker encases the mattress on all sides and uses the brand’s triple-seal closure system: an interior barrier flap, hook-and-loop fastener, and zipper. Its water-resistant layer is designed to help guard against stains, spills, and everyday irritants. The listing describes the fabric as breathable and quiet, with a construction intended to block dust-mite allergens.
The supplied dimensions are 72 by 84 inches with a 15-inch depth. Because mattress naming and dimensions can vary, compare those measurements with your mattress rather than relying on “King” alone. The cover is machine washable, but the care instructions specify no-heat tumble drying. Owners have noted that the zipper can catch on its protective guard if pulled quickly, so taking time during installation is sensible.
This model is a practical choice for a King mattress if you prefer a full encasement over a top-only protector. However, while the brand name refers to a bed bug blocker, the information provided here does not establish a formal bed-bug certification. Treat that as a point to verify if exclusion is the main reason you are shopping.
Pros:
- Six-sided coverage with a three-part zipper seal
- Water-resistant layer helps guard against spills and stains
- Designed to be breathable and quiet
- Machine washable with clear no-heat drying instructions
Cons:
- Listed dimensions may not match every mattress sold as King
- Careful zipper handling is needed to avoid catching the guard
Verdict: Consider this King option for a full-coverage, water-resistant encasement with a layered closure, after checking both mattress dimensions and pest-protection claims.
4. MATTSHIELD Ultimate King Mattress and Pillow Encasement Kit
MATTSHIELD’s kit includes a King mattress encasement and two zippered Queen-size pillowcase encasements. The mattress cover is listed for mattresses 12 to 17 inches thick and measures 76 by 80 inches. Its cotton terry surface is described as soft and breathable, while the six-sided layer is listed as waterproof for protection from spills and stains.
This set stands out from the single-cover options because it includes pillow encasements, too. It may suit a household looking to protect the mattress and pillows as a group, and its stated depth range gives shoppers a useful fit check. The product is described as bed-bug-proof, but the supplied details do not explain a certification or testing standard for that claim, so check the listing if formal pest protection is important to you.
Pay attention to the pillow sizing: the kit pairs a King mattress cover with two Queen-size pillow encasements. That may be useful if your pillows are Queen size, but it is not a matching King pillow set. The cover is machine washable, though the supplied information does not give a specific drying temperature.
Pros:
- Includes a mattress encasement and two zippered pillow encasements
- Listed to fit mattresses 12 to 17 inches thick
- Waterproof six-sided mattress protection
- Cotton terry surface is described as breathable
Cons:
- Pillow encasements are Queen size, not King size
- Bed-bug-proof claim should be checked against the manufacturer’s stated testing or certification
Verdict: Pick this kit if you want a waterproof King mattress cover plus Queen pillow encasements and your mattress falls within the stated depth range.
5. Four Seasons Essentials Waterproof Queen Encasement
This Queen-size polyester cover fully encases the mattress and is listed as waterproof. A zipper and Velcro seal close the enclosure, providing a barrier around all six sides. The stated dimensions are 80 by 60 by 14 inches, so this is a useful option to compare against a Queen mattress with a depth near 14 inches.
The main trade-off is care. Unlike the machine-washable Bed Bug Blocker models and MATTSHIELD kit, this encasement is listed for hand washing only. That may be a drawback if you expect to remove and clean the cover often. Some owners find that having another person help with installation makes it easier to position the encasement and guide the zipper.
The supplied details describe waterproof protection, but do not specify a bed-bug certification or guarantee. If you are comparing it with a product marketed for pest protection, review the manufacturer’s exact claims and closure details before deciding.
Pros:
- Six-sided, waterproof mattress coverage
- Velcro zipper seal helps cover the zipper closure
- Listed Queen dimensions include a 14-inch depth
- Polyester construction
Cons:
- Hand wash only, according to the supplied care information
- Specific bed-bug protection claims are not provided
Verdict: This is a sensible Queen option if waterproof coverage is your priority and you are comfortable with hand washing instead of machine laundering.
How to Choose a Zippered Mattress Cover With Bug Protection
Confirm the protection claim
A product name or general barrier description is not the same as a specific bed-bug certification. Check the manufacturer’s listing for the exact pest-protection claim, including whether it refers to bed bugs, dust mites, or other irritants. If you need a cover for a known pest problem, make sure the product’s stated purpose and instructions match your needs.
Measure the mattress size and depth
Measure the mattress length, width, and depth, including any pillow top or added layer that changes its overall thickness. Compare those measurements with the encasement’s stated dimensions. The options here have different fit information: the California King Bed Bug Blocker is listed at 72 by 84 by 15 inches, while MATTSHIELD gives a 12-to-17-inch depth range for its King model. Do not assume all products labeled King or Queen fit the same way.
Look closely at the zipper closure
A full encasement depends on a closure that can be shut securely. Some products in this selection add a flap or hook-and-loop tab over the zipper. Follow the manufacturer’s instructions, close the zipper fully, and avoid pulling it quickly if it catches on a guard. If pest protection is a key reason for buying, verify that the closure design supports the specific protection claim you need.
Choose the right level of liquid protection
Water-resistant and waterproof are not interchangeable terms. The Bed Bug Blocker models are described as water-resistant, while MATTSHIELD and Four Seasons Essentials are listed as waterproof. Consider what you need the cover to handle, such as occasional spills or more frequent accidents, and confirm the exact product wording before purchase.
Consider fabric feel and noise
The supplied information describes the Bed Bug Blocker covers as breathable and quiet, and MATTSHIELD has a cotton terry surface. Four Seasons Essentials is made from polyester, but the details provided do not describe its feel or noise level. If comfort is a priority, consider whether the cover’s surface and construction suit your preferences, and remember that a fitted sheet goes over the encasement.
Check washing and drying instructions
Care needs vary across these options. The Bed Bug Blocker models are listed as machine washable and call for no-heat tumble drying. MATTSHIELD is machine washable, while Four Seasons Essentials is listed for hand washing only. Choose a care routine you can maintain, and follow the instructions so you do not damage the cover or its protective layers.
Decide whether you need pillow protection
Most products here are mattress covers only. MATTSHIELD includes two Queen-size zippered pillow encasements with its King mattress cover. Check the pillow dimensions before choosing the kit, since the included pillow covers are not King size. If you only need mattress coverage, a single encasement may be the simpler fit.
Frequently Asked Questions
What is a zippered mattress encasement?
It is a cover that surrounds the mattress on all sides and closes with a zipper. This differs from a fitted protector, which usually covers the top and sides but leaves the mattress bottom open.
Does every product here guarantee bed-bug protection?
No. The supplied details describe some covers as barriers or use bed-bug-related branding, and MATTSHIELD’s description calls its product bed-bug-proof. However, the information provided does not establish a bed-bug certification or guarantee for every option. Check the manufacturer’s exact claim before buying for pest control.
Is water-resistant the same as waterproof?
No. Water-resistant material is designed to resist some moisture, while waterproof is a stronger stated level of protection. The Bed Bug Blocker models are described as water-resistant; MATTSHIELD and Four Seasons Essentials are listed as waterproof.
How do I know whether an encasement will fit?
Measure your mattress length, width, and depth, then compare those numbers with the product dimensions or stated depth range. Account for any topper or pillow-top layer that adds thickness. A close match can make installation easier and reduce excess fabric or tension.
Can I machine wash all of these covers?
No. The Bed Bug Blocker options are listed as machine washable, and MATTSHIELD is also machine washable. Four Seasons Essentials is listed for hand washing only. Always follow the care label and product instructions.
Is a mattress encasement waterproof if it has a zipper?
Not necessarily. A zipper describes the closure, not the cover’s liquid-protection level. Check whether the specific model is described as water-resistant or waterproof and read how its seams and closure are designed.
Does the MATTSHIELD kit include King-size pillow covers?
No. The supplied product details list two Queen-size pillowcase encasements with the King mattress cover. Check your pillow size before ordering the kit.
Final Recommendation
For a full zippered cover with a layered closure, the Bed Bug Blocker models are worth considering in the size that matches your mattress, with the California King option offering explicit dimensions in the supplied details. Choose MATTSHIELD if you want a waterproof King encasement and Queen pillow covers in one set. The Four Seasons Essentials option is a straightforward waterproof Queen cover, but its hand-wash-only care may not suit everyone. In every case, verify the fit and the manufacturer’s specific bed-bug protection claims before purchasing.
