A mattress encasement creates a zippered barrier around all sides of your mattress. For bed bug protection, the fit and closure matter: an encasement needs to cover the mattress completely and stay zipped shut. The options below also vary in mattress depth, waterproofing, fabric, and care, so check your mattress measurements before choosing.

Our Picks: Best Mattress Encasement For Bed Bugs reviews
HOSPITOLOGY PRODUCTS Sleep Defense System: A Flexible Queen Fit
This queen-size encasement is designed to fit mattresses from 12 to 18 inches deep. Its zippered cover surrounds the mattress on all six sides, while a waterproof barrier adds protection from spills and other liquids. The broader depth range may make it a useful option if your mattress is thicker than average or has a pillow top.
The cover uses a soft polyester knit fabric with a breathable waterproof membrane. That combination aims to provide a more comfortable feel than a stiff, crinkly cover. It is machine washable and can be tumble dried on low, and the product description lists a five-year limited manufacturer’s warranty.
HOSPITOLOGY is a practical pick if you want a queen encasement with a wide stated depth range and waterproof coverage. Before ordering, measure your mattress, including any attached pillow top, to confirm the fit. As with any bed bug encasement, the zipper needs to close fully and stay closed for the barrier to work as intended.
Pros:
- Fits queen mattresses from 12 to 18 inches deep
- Waterproof barrier covers all six sides
- Soft polyester knit is designed to be breathable
- Machine washable with a five-year limited warranty listed
Cons:
- Only the queen size and depth range are specified in the supplied product details
- The encasement needs careful installation to avoid stressing the zipper
Verdict: Choose the HOSPITOLOGY Sleep Defense System if you need a queen encasement with a particularly broad stated mattress-depth range and all-around waterproof coverage.
Utopia Bedding: A Straightforward Waterproof Queen Encasement
Utopia Bedding’s queen encasement covers all sides of a mattress measuring 60 by 80 inches and up to 15 inches deep. A wraparound zipper closes the cover, while stretchy knitted polyester is intended to help it fit securely without shifting.
The waterproof layer is TPU backing on all sides, which the product description says helps resist leaks. The fabric is described as soft and non-crinkling, and the encasement can be machine washed and tumble dried on low. Those details make it a useful choice if you want one cover for both a physical mattress barrier and routine spill protection.
Compared with the HOSPITOLOGY option, Utopia Bedding has a lower maximum stated depth. It may suit a standard-depth queen mattress, but check the measurement before buying, particularly if you have a thick mattress. A zipper closure alone does not replace proper installation: fully enclose the mattress and make sure the zipper is closed.
Pros:
- Full coverage for a queen mattress up to 15 inches deep
- Waterproof TPU backing is specified on all sides
- Stretchy knitted fabric is designed to fit securely
- Machine washable and suitable for low-heat tumble drying
Cons:
- Its stated depth limit is lower than the HOSPITOLOGY queen option
- The supplied details do not list a warranty
Verdict: Utopia Bedding is a sensible option for a queen mattress no deeper than 15 inches if you want a washable, waterproof encasement with a zippered closure.
SureGuard Premium: Cotton Terry and a Sealed-Zipper Design
SureGuard’s queen encasement fits mattresses from 13 to 16 inches deep. The product description highlights a super-fine zipper with Invisi-Zip and SureSeal technology, designed to seal the mattress from bed bugs. It also recommends using the encasement with a SureGuard box spring encasement for coverage of both pieces.
The six-sided protector is waterproof and has a cotton terry top intended to wick moisture while retaining the feel of the mattress. It is described as soft and noiseless, and the materials are listed as free from vinyl, PVC, phthalates, and fire retardants. The product is machine washable and dryable, independently lab tested, and GREENGUARD Gold certified. A 10-year quality guarantee is listed.
Its depth range is narrower than HOSPITOLOGY’s but extends one inch deeper than the Utopia Bedding option. The product description also suggests adding a fitted SureGuard protector on top for frequent accidents and easier cleanups, so consider that extra layer if spill management is a priority.
Pros:
- Sealed-zipper design is specifically described as a bed bug barrier
- Fits queen mattresses 13 to 16 inches deep
- Cotton terry top and waterproof six-sided protection
- Lists a 10-year quality guarantee and GREENGUARD Gold certification
Cons:
- Does not fit mattresses outside its stated 13-to-16-inch depth range
- The product description recommends an additional fitted protector for frequent accidents
Verdict: Consider SureGuard if your queen mattress is 13 to 16 inches deep and you value its specified zipper-sealing features, cotton terry surface, and listed quality guarantee.
Degrees of Comfort: A Queen Encasement with a Cotton Terry Top
This queen encasement is made for mattresses 13 to 15 inches deep. Its six-sided design uses a 360-degree micro-zipper closure, which the product describes as a barrier against bed bugs and household allergens. A TPU backing provides waterproof protection from spills, sweat, and other liquids.
The top is breathable cotton terry with a stain-release surface, and the fabric is designed to be quiet and snug rather than bunching up. The product details say its materials are OEKO-TEX Standard 100 certified. For care, the manufacturer advises a gentle machine-wash cycle and low-heat tumble drying. It also recommends moving the zipper gently during installation.
The 13-to-15-inch range makes this a close fit alternative to SureGuard for many queen mattresses, though the stated closure features and fabric differ. If installing the cover by yourself, its flexible corners are described as helping with one-person setup. Measure carefully, since this model has a two-inch depth range.
Pros:
- Six-sided design with a 360-degree micro-zipper closure
- Waterproof TPU backing and cotton terry top
- Designed for a quiet, snug fit on mattresses 13 to 15 inches deep
- OEKO-TEX Standard 100 certification is listed
Cons:
- Its stated mattress-depth range is limited to 13–15 inches
- Care instructions call for a gentle wash cycle and low-heat drying
Verdict: Degrees of Comfort is worth considering if your queen mattress is 13 to 15 inches deep and you want a waterproof encasement with a cotton terry top and micro-zipper closure.
Mattress Safe Sofcover: A King-Size Option with a Locking Zipper
Unlike the other picks here, the Mattress Safe Sofcover is listed for a king mattress measuring 76 by 80 inches. It fits mattresses 9 to 15 inches deep, making it the option to consider if you need a king-size encasement within that range.
The cover provides waterproof protection on all six sides and is described as breathable. Its patented “Zipper with the Hook” locking system is designed to secure the zipper closure. The product description also lists flammability testing to specified standards. Check the size and depth carefully, since this model will not fit a queen mattress.
Mattress Safe is the only king-size choice in this comparison. Its description focuses on waterproofing, airflow, fit, and the locking zipper, but does not give the same fabric or wash-care details as several of the queen models. If those details matter to you, confirm them with the product listing before purchase.
Pros:
- Fits king mattresses measuring 76 by 80 inches and 9 to 15 inches deep
- Waterproof barrier covers all six sides
- Breathable design is specified
- Uses a zipper system with a locking hook
Cons:
- King size only, so it is not suitable for queen mattresses
- The supplied description does not specify washing instructions or fabric feel
Verdict: Choose the Mattress Safe Sofcover if you need a king-size encasement that matches its 9-to-15-inch depth range and want a waterproof six-sided barrier with a locking zipper system.
How to Choose a Mattress Encasement for Bed Bugs
Measure the Mattress Size and Depth
Start with the mattress size, then measure its depth from the bottom edge to the top surface. Include an attached pillow top, but do not count loose bedding. Compare your measurements with the product’s stated range: a queen size alone does not guarantee that the encasement will fit a thick mattress. A cover that is too tight may be difficult to install, while excess fabric can bunch up.
Look for Full Coverage and a Secure Zipper
A mattress encasement should enclose the top, bottom, and sides—not just cover the sleeping surface. Check how the product describes its zipper and closure. Some options in this guide specify a sealed or locking zipper design, while others describe a wraparound or micro-zipper closure. Once installed, the mattress should be fully inside the cover and the zipper completely closed.
Consider Waterproofing and Fabric
Waterproof protection can help guard a mattress against spills, sweat, and stains, but materials affect the feel of the cover. These products include polyester knit, cotton terry, and TPU-backed designs. If you are sensitive to noise or warmth, review the fabric description and product details closely. The listed materials and features vary, so do not assume every encasement feels or performs the same way.
Check Washing and Drying Instructions
Care instructions matter because you may need to wash an encasement after a spill or as part of regular bedding care. Several products here are machine washable and specify low-heat tumble drying; Degrees of Comfort recommends a gentle cycle. Follow the instructions for the exact product you choose, since high heat or rough handling could damage a cover or its zipper.
Understand What an Encasement Can and Cannot Do
An encasement is a physical barrier around a mattress, not a complete bed bug treatment. It does not protect other parts of a room, such as bed frames or nearby furniture, and it does not replace addressing an infestation. For suspected bed bugs, consider getting guidance from a qualified pest control professional and follow their advice alongside any mattress protection.
Frequently Asked Questions
Can a mattress encasement help with bed bugs?
A fully closed encasement can create a barrier around the mattress. Choose a product described for bed bug protection, confirm the fit, and make sure the zipper is completely closed. An encasement alone does not treat an infestation elsewhere in the room.
Should I cover the box spring too?
If you want to enclose a box spring as well as the mattress, you need a separate box spring encasement sized for it. SureGuard’s product description specifically recommends pairing its mattress encasement with a SureGuard box spring encasement.
How do I know whether an encasement will fit?
Check both the mattress size and depth against the listed measurements. For example, the queen options in this guide have different depth ranges, from 12–18 inches for HOSPITOLOGY to 13–15 inches for Degrees of Comfort. Measure your mattress before ordering.
Can I put sheets over a mattress encasement?
Yes. The encasement is designed to surround the mattress, and bedding can go over it. Follow the product’s care and installation instructions, and avoid forcing the zipper while putting the cover on.
Are these encasements waterproof?
The supplied product descriptions list waterproof protection for all five options. Features and materials differ, so check the individual listing for details on the barrier, fabric, and care instructions.
How should I wash a mattress encasement?
Follow the care instructions for your specific model. Several options are machine washable and specify tumble drying on low; Degrees of Comfort recommends a gentle cycle. Avoid assuming that every cover can be washed or dried the same way.
Final Recommendation
For a queen mattress, HOSPITOLOGY stands out for its broad 12-to-18-inch depth range, while SureGuard offers a cotton terry top and a specifically described sealed-zipper design. Utopia Bedding and Degrees of Comfort are alternatives for queen mattresses within their stated depth limits. If you need a king-size cover, Mattress Safe is the only king option here. In every case, match the encasement to your mattress measurements and close the zipper fully; seek professional help if you suspect an active bed bug problem.
