The best bed bug mattress encasements do more than cover the top of a mattress. A true encasement surrounds the mattress on all six sides and closes with a zipper. However, mattress protection is only one part of the bed. Pillows and box springs can require separate products.
This guide compares three full mattress encasements plus two complementary protectors: a zippered pillow protector and a box spring encasement. Therefore, the products are not interchangeable. The comparison focuses on coverage, closure design, waterproofing, fit, care requirements and the limitations stated in the supplied listings.
Protect-A-Bed AllerZip in this guide is a pillow protector. CleanRest PRO is a box spring encasement. Mattress Safe, SureGuard and Utopia Bedding are the three full mattress encasements compared below.

BEST FOR PILLOWS 1. Protect-A-Bed AllerZip Pillow Protectors
Best for: Adding six-sided zippered protection to Queen-size pillows alongside a separate mattress encasement.
Protect-A-Bed AllerZip is different from the best bed bug mattress encasements because this product protects pillows rather than the mattress. The Queen package reviewed here includes two 20 × 30-inch protectors made from polyester.
Each protector surrounds the pillow and closes with a zipper. The listing also describes a flexible Liquidry waterproof layer, Bug Lock zipper technology and FUZE antimicrobial treatment. According to the manufacturer, the design is intended to create a barrier against bed bugs, dust mites and allergens while also protecting the pillow from liquids.
What we like
- Two Queen pillow protectors in the package
- Six-sided zippered construction
- Liquidry waterproof layer
- Machine washable
- Designed to remain breathable and quiet
What to know
- This product protects pillows, not the mattress or box spring
- Strong bed bug prevention claims come from the manufacturer
- A pillow protector does not replace a full mattress encasement
- Fit matters because the reviewed Queen size is 20 × 30 inches
The supplied listing recommends machine washing in hot water at 130°F. It also describes an inverted zipper edge intended to reduce snagging and a Bug Lock closure designed to secure the zippered opening.
Price seen: $16.93 for the Queen two-pack. Rating snapshot: 4.7/5 from 121 ratings, with 200+ bought in the past month on the supplied listing.

Best for: Full six-sided mattress coverage with a dedicated zipper-closing system.
Mattress Safe Sofcover Ultimate is one of the three true mattress encasements in this comparison. The Queen version is designed for a 60 × 80-inch mattress and fits depths from about 9 to 15 inches.
The encasement uses 100% polyester with a laminated polyurethane barrier. Moreover, the supplied listing describes all six sides as waterproof while still allowing airflow. Its patented hook-and-loop closure secures the zipper end, which is an important construction detail in a full encasement.
What we like
- Full six-sided mattress encasement
- Waterproof on all six sides according to the listing
- Polyester with laminated polyurethane barrier
- Breathable construction
- Patented hook-and-loop zipper closure system
What to know
- The supplied data did not include a current price or rating snapshot
- The exact 9–15 inch depth range should match your mattress
- Do not use bleach or borax products according to the care instructions
- The supplied material does not identify the independent bed bug certification body or test protocol
The listing says the encasement is machine washable and can tolerate elevated wash temperatures, with drying at a moderate temperature. It also references mattress-pad flammability testing. That flammability information is a material-safety characteristic, not evidence of bed bug performance.
Price seen: not included in the supplied product information. Check the live listing for the current Queen price.

Best for: Homeowners who want a six-sided waterproof mattress encasement with a cotton-terry sleep surface and several depth choices.
SureGuard combines full mattress coverage with a softer top surface than many basic polyester encasements. The Queen model measures 60 × 80 inches, while the reviewed configuration fits mattresses from 9 to 12 inches deep.
The top uses cotton terry, while the enclosure adds a waterproof backing. In addition, SureGuard uses its Invisi-Zip and SureSeal closure system. The manufacturer says this combination is designed to seal the mattress against bed bugs while also blocking liquids and common allergens.
What we like
- Six-sided waterproof mattress protection
- Cotton-terry top surface
- Four Queen depth ranges: 6–8, 9–12, 13–16 and 17–20 inches
- Invisi-Zip + SureSeal closure system
- Machine washable and machine dryable
- Listed as free of vinyl, PVC, phthalates and flame retardants
What to know
- Installation involves sliding the mattress into a full encasement
- The manufacturer recommends installation with two people
- Choose the depth range that matches your mattress rather than buying by bed size alone
- The GREENGUARD Gold certificate shown in the supplied content was dated through 2021, so this guide does not treat it as proof of current certification
Machine wash separately in cold water with mild detergent and no bleaching agents. Tumble dry on low or no heat with sheets or towels. The listing also says not to iron or dry clean the encasement.
Price seen: $64.97 for Queen, 9–12 inch depth. Rating snapshot: 4.6/5 from 15,101 ratings, with 1K+ bought in the past month.

Best for: Enclosing a box spring as a separate part of a broader bed-protection setup.
CleanRest PRO should not be confused with the best bed bug mattress encasements above. This product is made for the box spring. It completely encloses that component and uses the brand’s MicronOne allergen barrier with a Zip-N-Click closure.
The listing describes the material as micro-fleece and the enclosure as breathable, washable and water-resistant. CleanRest also recommends pairing the box spring cover with its PRO mattress encasement when greater insect resistance is the goal.
What we like
- Designed specifically for full box spring coverage
- MicronOne allergen barrier
- Zip-N-Click closure system
- Water-resistant construction
- 10-year PRO warranty stated in the listing
What to know
- This is not a mattress encasement
- It is described as water-resistant, not 100% waterproof
- A separate mattress encasement is needed to enclose the mattress
- The supplied listing uses broad insect-resistance language, so this guide does not convert that into an independent bed bug-proof claim
If your goal is to encase both the mattress and box spring, this product covers only the box spring. CleanRest recommends combining it with a separate mattress encasement.
Price seen: $45.99 for Queen. Rating snapshot: 4.5/5 from 113 ratings, with 50+ bought in the past month.

Best for: Shoppers who want straightforward six-sided mattress coverage without the more specialized closure systems used by some premium models.
Utopia Bedding is the simplest full mattress encasement in this comparison. The supplied listing describes 360° coverage, a soft knitted 100% polyester fabric, a waterproof barrier and a wraparound zipper.
The selected California King version measures 72 × 84 inches and fits mattresses up to 15 inches deep. The listing markets the product for insect and dust mite control. However, the supplied information does not identify a specific independent bed bug test or certification.
What we like
- Full six-sided mattress coverage
- 100% polyester knit fabric
- Waterproof liquid barrier
- Wraparound zipper closure
- Machine washable and tumble dry low
- Very large rating volume on the supplied Amazon listing
What to know
- The price supplied here is for California King, not Queen
- The selected variant fits mattresses up to 15 inches deep
- The listing’s bed bug claims are manufacturer claims rather than independently verified findings in this guide
- It does not list the specialized zipper-lock technologies found on SureGuard or Mattress Safe
The supplied Amazon snapshot was set to California King: 72 × 84 inches and up to 15 inches deep. Utopia also lists multiple other mattress sizes, so check both dimensions and depth before ordering.
Price seen: $41.52 for the selected California King version. Rating snapshot: 4.6/5 from 133,537 ratings, with 1K+ bought in the past month.
Check current price on AmazonWhich bed bug encasement or protector should you buy?
If you are shopping specifically for one of the best bed bug mattress encasements, focus first on Mattress Safe, SureGuard and Utopia Bedding. Those three products surround the mattress itself. SureGuard stands out for its cotton-terry top and multiple depth ranges. Mattress Safe emphasizes its patented zipper-closing system, while Utopia offers a simpler design.
Protect-A-Bed and CleanRest solve different parts of the same bedding problem. Protect-A-Bed encloses pillows, while CleanRest PRO encloses the box spring. Therefore, neither should replace a mattress encasement when the mattress itself needs full coverage.
A Queen label alone is not enough. Measure the mattress or box spring and verify its depth. A poorly matched encasement can be difficult to install, can leave excess material, or can put unnecessary stress on the zipper.
What matters most in a bed bug mattress encasement?
Start with six-sided coverage. A fitted mattress protector that covers only the sleep surface is not the same as a zippered encasement. Next, examine how the zipper closes because the opening is one of the most important construction details.
Fit also matters. Compare the product’s stated depth range with the actual mattress depth. Finally, consider whether you need waterproofing, a softer sleep surface, high-temperature washing or separate protection for the box spring and pillows.
When an encasement is not enough for bed bugs
A mattress encasement is a protective component, not a complete bed bug treatment plan. It does not remove insects hiding in bed frames, furniture, baseboards, wall voids or other areas of a room.
If you already have suspected bed bug activity, identify the pest correctly before relying on bedding products alone. Widespread activity, repeated bites or insects found away from the bed can justify a professional inspection and a broader treatment strategy.
Frequently asked questions
What is the difference between a mattress protector and a mattress encasement?
A mattress encasement surrounds all six sides of the mattress and closes with a zipper. A standard protector often covers only the top and sides. For the products reviewed here, Mattress Safe, SureGuard and Utopia are full mattress encasements.
Which of these products actually covers the mattress?
Mattress Safe Sofcover Ultimate, SureGuard Mattress Encasement and Utopia Bedding Zippered Mattress Encasement cover the mattress. Protect-A-Bed AllerZip covers pillows, while CleanRest PRO covers the box spring.
Is SureGuard waterproof?
The supplied SureGuard listing describes the encasement as 100% waterproof and says it provides six-sided protection against liquids and stains.
Is CleanRest PRO waterproof?
The supplied CleanRest PRO box spring listing describes the product as water-resistant. Therefore, this guide does not label it as 100% waterproof.
What size SureGuard should I buy for a Queen mattress?
The Queen model measures 60 × 80 inches, but you must also choose a depth range. The supplied listing offers 6–8, 9–12, 13–16 and 17–20 inch Queen options.
Does Protect-A-Bed AllerZip replace a mattress encasement?
No. The AllerZip product reviewed here is a pillow protector. It can complement a mattress encasement, but it does not surround or protect the mattress itself.
Is the Utopia Bedding price in this guide for Queen?
No. The supplied Amazon snapshot was set to California King at $41.52. Check the current listing for the price of the size you actually need.
The bottom line
The best bed bug mattress encasements in this group are the products that actually surround the mattress: Mattress Safe Sofcover Ultimate, SureGuard and Utopia Bedding. They differ mainly in closure design, surface material, fit options and price information available from the supplied listings.
Meanwhile, Protect-A-Bed AllerZip adds zippered pillow protection, and CleanRest PRO covers the box spring. For a more complete bedding setup, treat those as complementary products rather than substitutes for a mattress encasement.
