Our Picks: Best Mattress Case With Zipper reviews
Utopia Bedding: A Full-Size Waterproof Encasement
This full-size cover wraps around the mattress and closes with a zipper, providing coverage on all sides. It is designed for a 54-by-75-inch mattress up to 13 inches deep, so check your mattress measurements before ordering.
The smooth knitted polyester fabric is described as soft and quiet, while a waterproof layer helps block spills, sweat, and everyday accidents. That makes it a practical pick for a guest room or a bed used by children or pets. The cover is machine washable and can be tumble-dried on low heat.
Its main limitation is the size range: it is a full-size option, not a one-size-fits-all cover, and its maximum depth is 13 inches. If you have a thicker mattress or want a queen encasement, consider one of the other picks.
Pros:
- Full six-sided coverage with a zippered closure
- Waterproof barrier for common spills and moisture
- Quiet, stretchy knitted polyester fabric
- Machine washable and suitable for low-heat tumble drying
Cons:
- Fits full-size mattresses only
- Designed for mattresses up to 13 inches deep
Verdict: Choose this Utopia Bedding encasement if you have a full mattress within the stated depth limit and want an easy-care waterproof cover.
Four Seasons Essentials: A Flexible-Fit Queen Encasement
This six-sided queen encasement is made for mattresses 11 to 16 inches deep. Its polyester surface has a polyurethane inner lining to block liquids, and the stretch fabric is designed to stay quiet and comfortable beneath bedding.
The zipper wraps around three sides, so you can place the mattress into the open cover and close it around the bed rather than trying to push the whole mattress through a narrow opening. A Velcro zipper seal and an extra polyester lining around the zipper add coverage and support at the closure.
Keep in mind that the fit is limited to the listed queen dimensions and depth range. The three-sided zipper may make installation easier, but it still takes room to position the cover around a mattress. Compared with the SureGuard option, this model emphasizes a polyurethane barrier and flexible fit rather than a cotton terry top.
Pros:
- Six-sided waterproof construction
- Fits queen mattresses from 11 to 16 inches deep
- Three-sided zipper opening can simplify installation
- Machine washable
Cons:
- Fits queen mattresses only
- Mattresses outside the stated depth range may not fit securely
Verdict: This is a useful choice for a queen mattress if you want a waterproof encasement with a broad depth range and a zipper that opens along three sides.
SureGuard: A Premium Queen Cover with a Cotton Terry Top
SureGuard’s queen encasement fits mattresses 13 to 16 inches deep. It has a cotton terry top and a waterproof barrier on all six sides, with Invisi-Zip and SureSeal features intended to seal the zipper area against bed bugs. The product description also says it is independently lab tested and GREENGUARD Gold certified.
The cotton terry surface is designed to wick away moisture while retaining the feel of the mattress. SureGuard states that the cover is free from vinyl, PVC, phthalates, fire retardants, and other toxic chemicals. Its listed 10-year quality guarantee is a notable feature, though shoppers should review the guarantee terms before buying.
This encasement is a more specialized choice than the basic waterproof covers in this list. It only fits queen mattresses within its stated depth range. The product description also suggests adding a fitted mattress protector over the encasement if you expect frequent accidents and want easier cleanup.
Pros:
- Six-sided waterproof barrier with zipper-sealing features
- Cotton terry top designed to wick away moisture
- Fits queen mattresses from 13 to 16 inches deep
- Includes a stated 10-year quality guarantee
Cons:
- Does not fit mattresses shallower than 13 inches or deeper than 16 inches
- For frequent accidents, the product description recommends an additional fitted protector
Verdict: Consider SureGuard if you want a queen encasement with a cotton terry surface and added zipper-sealing features, and your mattress is within its depth range.
HOSPITOLOGY PRODUCTS: A Deep-Mattress Queen Encasement
The Sleep Defense System is a zippered queen encasement designed for mattresses 12 to 18 inches deep. Its waterproof barrier covers all six sides, and the extra-soft polyester knit fabric is described as breathable and comfortable. The breathable membrane is intended to help avoid trapping heat, though mattress temperature can also depend on your sheets and room conditions.
This is the deepest-fitting queen option in this lineup, making it worth a look if your mattress is too thick for the other covers. It is machine washable and can be tumble-dried on low. The product description says the cover can help reduce exposure to common substances that may reach the sleeper, but it should not be treated as a medical solution.
Its 12-to-18-inch fit range is helpful, but this remains a queen-only cover. Shoppers with a mattress outside that range should choose a different size or model rather than relying on stretch to make up the difference.
Pros:
- Fits queen mattresses from 12 to 18 inches deep
- Waterproof barrier on all six sides
- Soft polyester knit fabric with a breathable membrane
- Machine washable and tumble-dry friendly on low
Cons:
- Available in queen size in the supplied product details
- May not fit securely if the mattress depth is outside the stated range
Verdict: Choose this HOSPITOLOGY encasement if you need a queen cover for a deeper mattress and want full waterproof coverage.
Amazon Basics: A Simple Queen Encasement with Reinforced Seams
This queen-size encasement offers 360-degree zippered coverage and a waterproof barrier. Its flexible polyester fabric has a polyurethane backing, and the product description highlights reinforced seams for durability. A 12-inch pocket depth is listed, so measure your mattress carefully before choosing it.
The cover is described as breathable and noise-free, and it is machine washable and dryer-friendly. The fabric also contains 71% Global Recycled Standard-certified recycled post-consumer polyester, according to the product details. It is a straightforward option for shoppers who want a basic queen cover with waterproof protection and simple care.
The main fit consideration is its 12-inch pocket depth. Unlike the Four Seasons Essentials and HOSPITOLOGY options, the supplied details do not provide a broader depth range, so it may not suit a mattress much thicker than the stated pocket measurement.
Pros:
- 360-degree zippered coverage and waterproof barrier
- Flexible polyester fabric with polyurethane backing
- Reinforced seams and machine-washable design
- Contains recycled post-consumer polyester
Cons:
- Listed with a 12-inch pocket depth
- Supplied details specify queen size only
Verdict: This Amazon Basics option is a practical pick if you have a queen mattress that suits the 12-inch pocket depth and want a simple waterproof encasement.
How to Choose a Mattress Case With a Zipper
Measure the mattress size and depth
Start by checking the mattress length, width, and depth, including any pillow top or built-in padding. A cover that is too small may be hard to close, while a loose fit can shift. Compare your measurements with the listed size and depth range: for example, the Utopia Bedding cover is for a full mattress up to 13 inches deep, while the HOSPITOLOGY queen option fits depths from 12 to 18 inches.
Decide what kind of protection you need
All five products describe waterproof protection, but their other features vary. If your main concern is spills or moisture, look for a clearly stated waterproof barrier. If you also want a bed bug barrier, check the product’s claims about its zipper and closure. A zipper seal or specialized zipper design can be an important part of the encasement, but follow the product instructions for installation and closure.
Consider the cover’s surface and feel
The fabric is the part you may notice most once you make the bed. These options use knitted polyester or polyester blends, while SureGuard lists a cotton terry top. Look for descriptions of stretch, breathability, and noise if you are sensitive to a stiff or crinkly layer. A fitted sheet will cover the encasement, but the material underneath can still affect the feel of your bed.
Check how the zipper opens
A full encasement is more involved to put on than a fitted protector because you need to cover the sides and bottom of the mattress as well as the top. Some designs open along three sides, which can make it easier to position the mattress and close the cover. Before installation, make sure you have enough room around the bed to lift or turn the mattress as needed.
Review the care instructions
Most of these covers are described as machine washable, but drying guidance varies. For example, Utopia Bedding and HOSPITOLOGY specify tumble drying on low, while Amazon Basics describes the cover as dryer-friendly. Follow the label and product instructions so the waterproof layer and zipper stay in good condition.
Think about whether you need a separate fitted protector
An encasement covers the entire mattress, but some people may prefer a fitted protector on top for easier cleanup. SureGuard specifically recommends placing a fitted protector over its encasement when frequent accidents are expected. Consider your household’s needs and the extra laundry involved before deciding whether to layer products.
Frequently Asked Questions
What is the difference between a mattress encasement and a fitted protector?
A fitted protector usually covers the top and sides of a mattress, while an encasement surrounds all six sides and closes with a zipper. An encasement provides more complete coverage, but it generally takes more effort to install or remove.
How do I choose the right mattress depth?
Measure from the bottom edge of the mattress to its highest point, including any pillow top. Then compare that number with the product’s stated depth range or pocket depth. If you are between sizes, check the manufacturer’s fit details rather than assuming the fabric will stretch enough.
Can a zippered mattress case help protect against bed bugs?
Several products in this list describe features intended to help block bed bugs, including zipper seals or specialized zipper designs. For this type of protection, make sure the case fully encloses the mattress and follow its installation instructions. A mattress encasement is not a substitute for addressing an existing infestation.
Are zippered mattress encasements waterproof?
All five products in this guide describe a waterproof barrier. Check the product details for the specific materials and construction, and keep in mind that the zipper and seams are part of the overall closure. Proper installation and care matter for maintaining the intended coverage.
Will a mattress encasement change how my bed feels?
It can add a layer between the mattress and your sheets. The options here describe soft, stretchy, breathable, or quiet fabrics, but feel is personal. If texture or noise is a concern, pay close attention to the listed surface material and fabric details.
Can I wash a zippered mattress encasement?
The products in this roundup are described as machine washable. Care instructions differ, so check the label for the proper water temperature and drying method. Some specify low-heat tumble drying.
Final Recommendation
For a full-size mattress, the Utopia Bedding cover offers a clear fit range and waterproof, six-sided coverage. Among the queen options, Four Seasons Essentials stands out for its three-sided zipper and 11-to-16-inch fit range, while HOSPITOLOGY is the better match for a deeper mattress. Choose based on your measurements first, then compare the zipper design, surface material, and care instructions to find the best mattress case with a zipper for your bed.
