A zippered mattress encasement covers the top, bottom, and sides of your mattress, unlike a fitted protector that usually covers only the sleeping surface. For bed bug concerns, that full coverage and a secure zipper matter—but an encasement is not a replacement for professional pest control. The five Utopia Bedding options below offer different mattress sizes and depths, plus waterproof protection, so start by matching the cover to your mattress measurements.

Our Picks: Best Zippered Mattress Cover For Bed Bugs reviews
Best Queen Encasement for a 12-Inch Mattress
This queen-size Utopia Bedding encasement is made for a mattress measuring 60 by 80 inches and up to 12 inches deep. Its zippered design encloses all six sides, while the product description identifies it as a bed bug and dust mite barrier. It also adds a waterproof layer against spills and stains.
The smooth knitted polyester is described as breathable and quiet. Some owners say the cover fits snugly, feels comfortable under bedding, and does not make a crinkling sound. It is machine washable, which makes routine care more convenient, though you should follow the care instructions to help maintain the waterproof layer and zipper.
This is a practical match for a standard-depth queen mattress when you want both full encasement and liquid protection. Measure the mattress before ordering, especially if you use a topper or have a pillow-top bed; the listed 12-inch depth may not leave enough room for a taller mattress setup.
Pros:
- Full coverage for a queen mattress up to 12 inches deep
- Zippered closure and stated bed bug and dust mite protection
- Waterproof barrier for everyday spills and stains
- Machine washable and described as soft and quiet
Cons:
- May be too shallow for thicker mattresses or mattress-and-topper combinations
- Putting a full encasement on a mattress can take more effort than fitting a standard protector
Verdict: Choose this queen version if your mattress is no more than 12 inches deep and you want a washable, waterproof encasement.
Best King Encasement for Extra Mattress Depth
This king-size option fits a mattress measuring 78 by 80 inches and up to 15 inches deep. That extra depth gives it an advantage over the 12- and 13-inch options in this guide if your king mattress is tall. The stretchy polyester fabric and wrap-around zipper are designed to enclose the mattress and help the cover stay in place.
Its waterproof barrier is intended to block spills, sweat, and other everyday liquids. The fabric is described as smooth and non-crinkling, and the cover can be machine washed and tumble dried on low heat. Some owners find the king-size version manageable to install, while others note that a second person can make the job easier.
Compared with the queen and full options, this is the one to consider for a deeper king mattress. The trade-off is that a large encasement can be awkward to handle during installation and laundering. Check the mattress dimensions carefully, including any topper you plan to keep in place.
Pros:
- Fits king mattresses up to 15 inches deep
- Encloses all sides with a zippered closure
- Waterproof protection and machine-washable care
- Non-crinkling fabric is designed for quiet use
Cons:
- Large size may be difficult to install alone
- May not fit mattresses deeper than 15 inches
Verdict: This is the best fit in the group for a king mattress that needs more depth than the 12-inch versions allow.
Best Full Encasement for Mattresses up to 13 Inches
This full-size encasement is listed for mattresses measuring 54 by 75 inches and up to 13 inches deep. It covers all sides and uses a wrap-around zipper. The product information describes it as a waterproof mattress cover with bed bug and dust mite protection.
The smooth polyester fabric is intended to lie flat without the stiff, noisy feel some people associate with waterproof covers. Its extra inch of depth over the other full-size option may help if your mattress is slightly taller or you are covering a mattress with a thin topper. Take a depth measurement before buying rather than relying on the mattress label alone.
This version shares the main features of the other Utopia Bedding encasements, including a machine-washable design. Its main distinction is fit: it offers a little more depth than the 12-inch full model, but it will not be the right choice if your mattress is deeper than 13 inches.
Pros:
- Fits full mattresses up to 13 inches deep
- Full encasement with a secure zippered closure
- Waterproof barrier and stated bed bug protection
- Machine washable with smooth, quiet polyester fabric
Cons:
- Not as deep as the king option for extra-tall mattresses
- Measure any topper as part of the total mattress depth
Verdict: Pick this full-size model over the 12-inch version if your mattress needs the added depth and measures no more than 13 inches.
Best Standard-Depth Full Encasement
This Utopia Bedding full encasement is designed for a 54-by-75-inch mattress up to 12 inches deep. It gives you the same basic all-around coverage as the deeper full-size model, with a waterproof layer and a zippered closure. The listed features also include bed bug and dust mite protection.
The knitted polyester is described as soft, breathable, and quiet. Since this model is one inch shallower than the 13-inch full option, it is a better match for a standard-depth mattress without a thick topper. A snug fit matters for an encasement, so avoid choosing a smaller depth just to get a tighter cover.
This is a straightforward option if your full mattress fits the stated dimensions and you do not need the extra depth of the other full-size model. Both full choices share similar protection and care features, so mattress height is the main deciding factor.
Pros:
- Designed for full mattresses up to 12 inches deep
- Six-sided coverage with a zippered closure
- Waterproof and machine washable
- Soft, quiet knitted fabric
Cons:
- Less depth than the 13-inch full-size alternative
- May be difficult to fit over a thick topper or taller mattress
Verdict: Choose this model for a standard-depth full mattress; select the 13-inch version if your measured setup is taller.
Best Twin Encasement for a Compact Bed
This twin version is designed for a 39-by-75-inch mattress up to 12 inches deep. Like the other covers here, it fully encloses the mattress with a zipper and adds waterproof protection. The product information also identifies it as a bed bug and dust mite barrier.
The twin size is easier to maneuver than a king encasement, which can make installation simpler on a child’s bed, guest bed, or other compact mattress. The cover is machine washable and made with smooth knitted fabric. Some owners report that it fits well and stays quiet, but the actual fit depends on matching the cover to your mattress dimensions.
For a twin mattress that is taller than 12 inches, consider a different size or product with a deeper pocket. A cover that is stretched too tightly may be harder to zip and may not sit as intended.
Pros:
- Fits twin mattresses up to 12 inches deep
- Full zippered coverage with stated bed bug protection
- Waterproof and machine washable
- Compact size is easier to handle than larger encasements
Cons:
- Limited to twin mattresses within the listed dimensions
- Not suited to a mattress deeper than 12 inches
Verdict: This is a sensible choice for a standard-depth twin mattress when you want full encasement and waterproof coverage.
How to Choose a Zippered Mattress Cover for Bed Bugs
Choose the Right Mattress Size
Start with your mattress size and compare its width and length with the product listing. Queen, king, full, and twin covers are not interchangeable, and even a cover labeled with the right size can fit poorly if the mattress dimensions differ. If your mattress has an unusual shape or size, check the measurements closely before ordering.
Measure the Full Mattress Depth
Measure from the bottom edge to the top of the mattress, including a topper if you plan to leave it in place inside the encasement. The options here range from 12 to 15 inches deep. The cover should fit without being overstretched, so choose a depth that accommodates your complete mattress setup.
Look for Full Encasement and a Zippered Closure
A fitted protector typically covers the top and sides, while an encasement surrounds the mattress on all sides. For bed bug concerns, check that the listing describes a full zippered encasement and follow the product instructions for closing it. Do not assume that a waterproof fitted sheet provides the same coverage.
Understand What the Protection Does
The products in this guide are described as bed bug and dust mite protective, and each includes a zippered closure. An encasement can help protect or isolate the mattress when used as directed, but it does not treat bed bugs elsewhere in a room or home. If you suspect an infestation, consider professional pest-control advice and follow their guidance.
Decide Whether Waterproofing Matters
All five picks are described as waterproof, which can help shield the mattress from spills and everyday moisture. This can be useful if you have children, pets, or a mattress you want to keep clean. Waterproofing is an added benefit, but it does not replace checking the fit and closure for bed bug-related use.
Consider Fabric, Noise, and Care
The listed covers use polyester fabric and are described as smooth and quiet. All are machine washable, though the king model specifically lists tumble drying on low heat. Check the care label before washing or drying, and use the stated instructions to help preserve the cover’s condition.
Plan for Installation
A full encasement needs to be fitted around the whole mattress, so installing it may take more time than putting on a standard mattress protector. A larger mattress can be awkward to lift and maneuver. Make sure you can close the zipper without forcing it, and follow the included instructions for proper installation.
Frequently Asked Questions
Does a zippered mattress encasement stop bed bugs?
The products listed here are described as bed bug protective encasements. Their full coverage and zipper are intended to enclose the mattress, but an encasement alone does not address bed bugs elsewhere in a room or home. Follow the product directions and seek pest-control guidance if you suspect an infestation.
What is the difference between an encasement and a mattress protector?
An encasement surrounds the mattress on all sides and closes with a zipper. A typical fitted mattress protector covers the top and usually wraps around the edges, but does not fully enclose the mattress.
How do I know which depth to order?
Measure the mattress from top to bottom, including any topper that will stay inside the cover. Then choose a model whose listed maximum depth accommodates that measurement. The options in this guide fit mattresses from 12 to 15 inches deep, depending on the size.
Can I wash these mattress covers?
The product details identify all five as machine washable. Follow the care instructions on the product label. The king-size model specifies tumble drying on low heat; do not assume the same drying instructions apply to every version.
Will the cover make noise while I sleep?
The product descriptions characterize the polyester fabric as soft and non-crinkling, and some owners report that it stays quiet during use. How it feels can depend on your bedding and personal preference.
Can I put a mattress topper inside the encasement?
That may work if the combined depth of the mattress and topper stays within the cover’s listed limit. Measure the full setup before buying, since a topper can make an otherwise suitable cover too shallow.
Is waterproofing the same as bed bug protection?
No. Waterproofing is meant to block liquids, while bed bug protection depends on the encasement’s full coverage and closure. These products list both features, but each serves a different purpose.
Final Recommendation
For most shoppers, the best choice is the Utopia Bedding encasement that matches the mattress size and depth most closely. The queen, twin, and 12-inch full versions suit standard-depth mattresses, while the 13-inch full model and 15-inch king model offer more room for taller beds. Whichever you choose, measure first, follow the installation and care instructions, and treat an encasement as one part of a broader plan if you suspect bed bugs.
