A zippered mattress encasement can help protect a queen mattress by covering all six sides and closing it inside a barrier. For bed bug concerns, fit and an intact zipper closure matter as much as the fabric: a cover is one part of a plan, not a substitute for addressing an infestation. Measure your mattress, including any topper you plan to keep under the encasement, before choosing a depth.

Our Picks: Best Queen Mattress Encasement For Bed Bugs reviews
Best for a snug fit on a standard-depth mattress: Utopia Bedding 12-Inch Queen Encasement
This six-sided Utopia Bedding encasement is made for a standard queen mattress measuring 60 by 80 inches, with a pocket depth of up to 12 inches. Its zippered closure covers the mattress, while the waterproof design also helps shield it from spills and stains.
The smooth knitted polyester fabric is described as breathable and quiet, which may suit sleepers who dislike a stiff or noisy layer under their sheets. It is machine washable, giving you a straightforward care option. For bed bug protection, check that the zipper is fully closed and the fabric remains intact after fitting and washing.
Its main limitation is the 12-inch depth. If your mattress is taller, or you plan to leave a thick topper in place, this model may be too tight. Compared with the deeper Utopia option below, it makes more sense when you want a closer fit on a mattress that falls within its stated dimensions.
Pros:
- Made for a standard queen mattress with a 12-inch depth limit
- Zippered, six-sided coverage
- Waterproof and machine washable
- Soft knitted fabric is designed to stay quiet and breathable
Cons:
- May not fit a mattress deeper than 12 inches
- Fit can be too tight if you include a bulky topper
Verdict: Choose this model if your queen mattress is no more than 12 inches deep and you want a washable, waterproof encasement with a snug fit.
Best for a low-profile mattress: Utopia Bedding 10-Inch Queen Encasement
This queen-size Utopia Bedding encasement has the same core approach as the 12-inch option: a zippered cover intended to enclose all sides, plus waterproof protection for the mattress. Its listed 10-inch depth makes it a better match for shorter mattresses that could feel loose inside a deeper cover.
The polyester fabric is described as smooth and breathable, and the encasement can be machine washed. The shorter pocket is the key buying detail. Measure the mattress itself, and include any topper that will stay in place; a cover that is stretched too tightly can be harder to install and may put extra strain on its seams or zipper.
Compared with the other queen Utopia models here, this is the most restrictive choice for mattress height. It is not the one to pick for a thick mattress, but it may be a more appropriate fit than a deeper-pocket model if your mattress is close to 10 inches tall.
Pros:
- 10-inch depth option for shorter queen mattresses
- Zippered design intended to enclose all sides
- Waterproof and machine washable
- Smooth knitted polyester fabric
Cons:
- Limited to mattresses up to 10 inches deep
- Less flexible than deeper models if you change mattresses
Verdict: Pick this encasement only if your mattress height is within its 10-inch limit; taller beds call for a deeper model.
Best for thicker mattresses: HOSPITOLOGY PRODUCTS Sleep Defense System
The Sleep Defense System is designed for a standard queen mattress and fits depths from 12 to 18 inches. That range gives it more room for taller mattresses than the 10- and 12-inch Utopia options. The product description specifies a waterproof barrier on all six sides and says the barrier has been lab-tested.
The cover combines a polyester face with a polyurethane lining. Its breathable waterproof membrane is intended to help avoid a hot or crinkly feel, while the machine-washable design makes routine care easier. The supplied product information also lists a five-year limited manufacturer’s warranty; check the warranty terms for conditions and eligibility.
Some users report that the fabric and zipper feel sturdy and that the cover is quiet in use. As with any full encasement, installation can take more effort than putting on a fitted-sheet-style protector, especially on a heavy mattress. Make sure the queen size and depth range match your bed before ordering.
Pros:
- Fits queen mattresses from 12 to 18 inches deep
- Waterproof barrier covers all six sides
- Machine washable and tumble dryable on low heat
- Includes a five-year limited manufacturer’s warranty
Cons:
- May be too roomy for a mattress shallower than 12 inches
- Full encasements can take more effort to put on than fitted protectors
Verdict: This is a strong option if your queen mattress is at least 12 inches deep and you want a waterproof, six-sided cover with a broad fit range.
Best for a wider-than-standard bed: Utopia Bedding Super Queen Encasement
This Utopia Bedding model is made for a super queen mattress measuring 66 by 80 inches and up to 15 inches deep. That is wider than a standard queen, so it is important not to assume it will fit a 60-by-80-inch mattress. Check your bed’s actual dimensions before buying.
The encasement has a zippered closure, waterproof barrier, and smooth knitted polyester fabric. The product description calls the fabric non-crinkling and says the stretchy cover is designed to stay in place. It is machine washable and can be tumble dried on low heat.
Its wider dimensions are both its main advantage and its biggest drawback. If you own a standard queen mattress, one of the standard queen options in this guide is a more suitable choice. If your bed measures 66 by 80 inches, this model offers full coverage with more depth allowance than the 10- and 12-inch covers.
Pros:
- Designed for a 66-by-80-inch super queen mattress
- Fits mattresses up to 15 inches deep
- Waterproof, zippered, and machine washable
- Fabric is designed to be soft and quiet
Cons:
- Too wide for a standard 60-by-80-inch queen mattress
- Putting on a full encasement may be easier with help
Verdict: Choose this only if your mattress measures super queen size; for a standard queen, select a cover with 60-by-80-inch dimensions.
Best standard queen option for added mattress depth: Utopia Bedding 15-Inch Encasement
This Utopia Bedding encasement is sized for a standard 60-by-80-inch queen mattress up to 15 inches deep. It keeps the familiar queen footprint while allowing more height than the 10- and 12-inch models. A waterproof TPU backing is listed on all sides, and the wraparound zipper is intended to enclose the mattress.
The smooth knitted polyester is described as quiet and soft, and the cover is machine washable and suitable for tumble drying on low heat. Some users report that the material does not make a crinkling sound during sleep. Even so, fabric feel can vary by sleeper, and the encasement sits beneath your fitted sheet.
The 15-inch depth gives this model more flexibility if you have a taller mattress or a topper you plan to leave in place. If your mattress is much shallower, a smaller pocket may give a closer fit. This model and the 12-inch Utopia option share the same standard queen dimensions, but this one is the better match for extra height.
Pros:
- Fits standard queen mattresses up to 15 inches deep
- Waterproof TPU backing on all sides
- Zippered full coverage and machine-washable care
- Quiet knitted polyester fabric
Cons:
- May be looser on a shallow mattress
- Does not fit a mattress wider or longer than standard queen dimensions
Verdict: This is a practical standard queen pick if your mattress is too deep for a 10- or 12-inch encasement but no more than 15 inches tall.
How to Choose a Queen Mattress Encasement for Bed Bugs
Measure the mattress before choosing a size
A standard queen mattress is 60 by 80 inches, but its depth varies. Measure the mattress from top to bottom, including any topper that will stay under the cover. Choose a pocket depth that can fit the full stack without stretching tightly. If your mattress is a different width or length, such as the 66-by-80-inch super queen listed above, select an encasement made for those dimensions.
Look for full, zippered coverage
A mattress encasement is designed to cover the top, bottom, and sides, then close around the mattress with a zipper. For bed bug concerns, a fully closed cover with no tears or gaps is important. Follow the product’s fitting instructions and check the zipper and seams when you put it on.
Consider the zipper and fabric together
The zipper is part of the barrier, so avoid forcing it around an overfilled or oversized mattress. Look for a cover that fits without excessive strain, and handle the fabric carefully during installation and washing. If you notice a tear or a closure that will not stay shut, the encasement may no longer provide reliable coverage.
Decide whether waterproof protection matters
All five options in this guide are described as waterproof, which can help protect a mattress from spills and stains as well as provide an enclosed cover. If liquids are a concern, check that the product’s waterproof layer covers the areas you need and follow its care instructions to maintain the material.
Check care instructions and warranty terms
Machine washing can make upkeep easier, but follow each product’s stated washing and drying directions. High heat or rough handling may affect fabric and closures. The HOSPITOLOGY option lists a five-year limited manufacturer’s warranty; check its terms to understand what is covered and what steps are required for a claim.
Use an encasement as one part of bed bug control
A mattress cover can help isolate the mattress, but it does not treat bed bugs elsewhere in a room or home. If you suspect an infestation, seek guidance from a qualified pest-control professional and follow their instructions. Keep the encasement closed and intact rather than removing it as a stand-alone fix.
Frequently Asked Questions
Does a mattress encasement get rid of bed bugs?
No. An encasement is a protective cover, not a treatment for a whole-room or home infestation. It may help enclose the mattress, but other affected areas still need attention. For suspected bed bugs, consult a qualified pest-control professional.
Is a mattress protector the same as an encasement?
Not always. Many mattress protectors cover only the top and sides, while an encasement is designed to surround all six sides and close with a zipper. Check the product description and dimensions to confirm the coverage style.
How deep should my queen mattress encasement be?
Measure your mattress from top to bottom, including any topper that will remain under the cover. The cover should fit the full depth without being stretched tightly. The options here range from 10 to 18 inches for standard queen sizes, while the super queen model has different width and length measurements.
Can I put sheets over a mattress encasement?
Yes. An encasement sits around the mattress, and you can place your usual fitted sheet over it. Make sure the fitted sheet does not pull the encasement out of place or strain its zipper.
Can I wash a bed bug mattress encasement?
The five products listed here are described as machine washable. Follow the specific product’s washing and drying instructions, and inspect the fabric and zipper afterward for damage.
Which option is best for a thick queen mattress?
For a standard queen mattress between 12 and 18 inches deep, the HOSPITOLOGY Sleep Defense System has the broadest stated depth range. The Utopia Bedding 15-inch model is another option if your mattress is no more than 15 inches deep.
Final Recommendation
For most standard queen mattresses, the Utopia Bedding 15-inch encasement offers a useful balance of full coverage, waterproof protection, and extra room for mattress depth. If you prefer a closer fit and your mattress is 12 inches deep or less, consider the 12-inch model instead. For a thick mattress, the HOSPITOLOGY option covers a wider depth range. Measure first, keep the zipper and fabric intact, and treat an encasement as one part of a broader bed bug response.
