A waterproof bed bug mattress protector should do more than shield the top of your bed. A zippered encasement covers the mattress on all sides, while a secure closure helps seal it off from bed bugs and dust mites. The picks below also provide a waterproof barrier, but they differ in mattress-depth fit, surface fabric, and included details. Check your mattress measurements before choosing, especially if it is unusually deep.

Our Picks: Best Waterproof Bed Bug Mattress Protector reviews
1. SureGuard: A Cotton-Terry Encasement With a Secure Closure
The SureGuard is a six-sided Queen mattress encasement made for mattresses that are 13 to 16 inches deep. Its cotton terry top is designed to wick away moisture while keeping the feel of the mattress, and the encasement is made without vinyl, PVC, phthalates, or fire retardants, according to the product details.
For bed bug protection, the listing highlights a fine zipper with Invisi-Zip and SureSeal technology. The design fully encloses the mattress, so careful installation and fully closing the zipper matter. It is machine washable and dryer-safe, and the manufacturer includes a 10-year quality guarantee. The listing also says it was independently lab tested and is GREENGUARD Gold certified.
This is a strong fit for shoppers who want a cotton surface and a stated mattress-depth range. One practical limitation: the manufacturer suggests adding a fitted SureGuard protector over the encasement for frequent accidents and easier cleanup. That extra layer may be useful, but it is an additional purchase.
Pros:
- Cotton terry top with moisture-wicking properties
- Invisi-Zip and SureSeal closure technology
- Waterproof protection on all six sides
- Machine washable and dryer-safe
Cons:
- Fits only mattresses 13 to 16 inches deep
- Frequent spills may be easier to manage with a separate fitted protector over it
Verdict: Choose the SureGuard if your Queen mattress fits its depth range and you prefer a cotton terry surface with a specifically described zipper-sealing system.
2. Utopia Bedding: A Smooth, Breathable 12-Inch Encasement
This Utopia Bedding model is a six-sided Queen encasement designed for a 60-by-80-inch mattress with a 12-inch-deep pocket. It has a smooth knitted fabric that the product description says is breathable and does not trap heat. The listing also describes it as soft and quiet, which may appeal if you want an encasement that does not feel stiff or noisy under your sheets.
A zippered closure provides the full-mattress enclosure, and the product is described as waterproof as well as protective against bed bugs and dust mites. It is machine washable for routine care. Because the pocket is specified as 12 inches deep, measure your mattress rather than relying on the Queen size alone; this model may not suit a thicker mattress.
Compared with the other Utopia Bedding option here, this version has a more limited stated depth fit. Its advantage is a clear, snug-fit specification for a standard-depth mattress and a smooth knitted surface.
Pros:
- Six-sided zippered coverage
- Waterproof and designed to protect against bed bugs and dust mites
- Smooth knitted fabric described as breathable and quiet
- Machine washable
Cons:
- The 12-inch pocket limits fit for deeper mattresses
- The description does not specify a warranty
Verdict: This is a practical option if your Queen mattress is close to 12 inches deep and you want a smooth, washable encasement.
3. Utopia Bedding: Flexible Fit With Waterproof Backing on Every Side
This Queen-size Utopia Bedding encasement fits mattresses up to 15 inches deep. Its stretchy knitted polyester is designed to slip on easily and stay in place, while a wraparound zipper encloses all sides. The product description specifies TPU waterproof backing on all sides, so the barrier is not limited to the sleeping surface.
The fabric is described as soft and non-crinkling, a useful feature if you want waterproof coverage without a stiff feel. It is machine washable and can be tumble-dried on low heat. This model also claims protection against bed bugs and dust mites, making it a versatile choice for shoppers who want an all-around zippered barrier.
Its depth range is broader than the 12-inch Utopia model, though it still may not fit mattresses deeper than 15 inches. The supplied product details do not give a warranty or describe a special zipper-sealing feature beyond the wraparound closure, so shoppers who prioritize detailed closure technology may prefer the SureGuard.
Pros:
- Fits Queen mattresses up to 15 inches deep
- TPU waterproof backing covers all sides
- Soft, stretchy fabric with a non-crinkling design
- Machine washable and tumble-dryable on low
Cons:
- Does not fit mattresses deeper than 15 inches
- The product details do not specify a warranty
Verdict: Pick this model if your mattress is no more than 15 inches deep and you want all-side TPU backing with a soft, stretchy fabric.
4. HOSPITOLOGY: A Breathable Encasement for Deeper Mattresses
The HOSPITOLOGY Sleep Defense System is a six-sided Queen encasement that stretches to fit mattresses from 12 to 18 inches deep. That wider range makes it worth considering if your mattress is too deep for the two Utopia Bedding models above. Its soft polyester knit is paired with a breathable waterproof membrane, according to the product description.
The listing describes the barrier as 100% waterproof on all six sides and says it is lab-tested. It is machine washable and should be tumble-dried on low. A five-year limited manufacturer’s warranty is also listed. This model is designed to protect against bed bugs and dust mites, but as with any encasement, it needs to fit correctly and be fully zipped to provide the intended coverage.
The trade-off is that the fabric is polyester knit rather than cotton terry. If a cotton-touch surface is your priority, the SureGuard or PlushDeluxe may be a closer match, though the HOSPITOLOGY’s 12-to-18-inch fit range is the broadest stated range among these picks.
Pros:
- Fits Queen mattresses from 12 to 18 inches deep
- Waterproof barrier on all six sides
- Soft knit fabric with a breathable membrane
- Machine washable and includes a five-year limited warranty
Cons:
- Uses polyester knit rather than a cotton terry surface
- Requires low-heat tumble drying
Verdict: The HOSPITOLOGY encasement is a good match for a deeper Queen mattress if you want a broad fit range, all-side waterproofing, and a stated warranty.
5. PlushDeluxe: Cotton Terry With a Zipper Flap
The PlushDeluxe is described as a waterproof, six-sided mattress encasement with a soft cotton terry surface. Its listing says the fabric is free from vinyl, PVC, and phthalates, and that a breathable membrane allows air to circulate while repelling liquids. A fine invisible zipper and Velcro flap are intended to secure the enclosure.
One important detail needs checking before you order: the product title identifies this as a Queen model, but the supplied description refers to a Full mattress cover. The description also does not provide a mattress-depth range. Confirm the size and dimensions on the product listing before buying, especially if you have a Queen bed or a deep mattress.
If the size is right, the cotton terry top and extra zipper flap may appeal to shoppers who want a softer-feeling surface and a covered zipper. Unlike the SureGuard, the supplied details do not state a mattress-depth range or warranty, so there is less information to use when checking fit and long-term coverage.
Pros:
- Cotton terry surface described as soft
- Waterproof coverage on all six sides
- Invisible zipper with a Velcro flap
- Machine washable and low-heat tumble-dryable
Cons:
- The title and description give different mattress sizes
- No mattress-depth range is provided in the supplied details
Verdict: Consider the PlushDeluxe if you want a cotton terry encasement, but verify the exact size and depth fit on the listing before purchasing.
How to Choose a Waterproof Bed Bug Mattress Protector
Measure the mattress, including its depth
Start with the mattress size and measure its depth from the bottom edge to the top surface. A Queen label does not tell you whether an encasement will fit a thick mattress. The models here have different stated limits: one fits 12 inches, another fits up to 15 inches, the SureGuard fits 13 to 16 inches, and the HOSPITOLOGY covers 12 to 18 inches. For the PlushDeluxe, verify both size and depth because the supplied product details do not clearly establish them.
Choose a full encasement with a secure zipper
A fitted protector covers the sleeping surface and sides, while an encasement wraps around the entire mattress. For bed bug protection, look for a zippered design that encloses all sides and has a way to secure or cover the zipper opening. Follow the product’s installation instructions and check that the closure is fully fastened. The SureGuard specifically describes Invisi-Zip and SureSeal technology, while the PlushDeluxe lists an invisible zipper with a Velcro flap.
Check that the waterproof barrier covers all sides
If you want protection from spills, perspiration, or stains, confirm that the waterproof layer is intended to cover the whole mattress, not only the top. All five picks are described as waterproof encasements, and several specifically state that their barrier covers all six sides. The Utopia Bedding model with TPU backing explicitly places that backing on all sides.
Consider the fabric and feel
The surface fabric can affect how the encasement feels under your sheets. SureGuard and PlushDeluxe use cotton terry tops. The Utopia Bedding models and HOSPITOLOGY use knitted fabrics, described as smooth, soft, or breathable in their product details. If you are sensitive to noise or stiffness, look for a fabric description that addresses those concerns; the Utopia options are described as quiet or non-crinkling.
Review care instructions and warranty details
Washability matters because the encasement stays on the mattress during regular use. These products are described as machine washable, but drying instructions vary: the Utopia models specify low-heat tumble drying, and HOSPITOLOGY also says to tumble dry on low. The listed warranty terms differ as well. SureGuard states a 10-year quality guarantee, while HOSPITOLOGY lists a five-year limited manufacturer’s warranty. Check the product listing for current care directions and warranty terms before ordering.
Plan for installation and everyday use
Putting a full encasement on a mattress takes more handling than fitting a top-only protector, so check the instructions and make sure you can access the mattress sides. Once installed, use fitted sheets as usual and avoid leaving the zipper partly open. If frequent spills are a concern, the SureGuard description suggests adding a fitted protector over the encasement for easier cleanup.
Frequently Asked Questions
What is the difference between a mattress protector and a mattress encasement?
A fitted mattress protector usually covers the top and sides, while an encasement surrounds the mattress on all sides and closes with a zipper. For a bed bug-focused product, check that the encasement fully closes and fits the mattress properly.
Can a waterproof mattress encasement also protect against bed bugs?
Some products are designed for both purposes. The five options here are described as waterproof and as offering bed bug protection. Check the product details for the closure design, fit range, and any specific instructions for using the encasement.
How do I know whether an encasement will fit?
Measure the mattress length, width, and depth, then compare those measurements with the product’s listed size range. Pay close attention to depth: a Queen encasement that fits a 12-inch mattress may not fit one that is 16 inches deep.
Will a waterproof encasement change how my mattress feels?
Feel can vary by fabric and construction. The products here use cotton terry or knitted fabric, and several are described as soft, smooth, quiet, or non-crinkling. Your sheets and mattress may also affect how the encasement feels in use.
Can I machine wash these mattress encasements?
All five product descriptions say they are machine washable. Drying instructions can differ, so follow the care directions for the specific model. Some of these listings specify low-heat tumble drying.
Which option is best for a deep Queen mattress?
Among these choices, HOSPITOLOGY lists the broadest fit range at 12 to 18 inches deep. The SureGuard fits 13 to 16 inches, while the other Utopia model fits up to 15 inches. Measure your mattress before choosing.
Final Recommendation
The SureGuard is the strongest all-around choice if your mattress is 13 to 16 inches deep and you want a cotton terry surface plus a specifically described zipper-sealing system. For a deeper mattress, the HOSPITOLOGY encasement has the broadest stated fit range. If you prefer a smooth knitted surface, consider the Utopia Bedding models, choosing between the 12-inch version and the model that fits up to 15 inches. Whichever you select, confirm the dimensions and follow the installation and care instructions for a proper fit.
