A mattress encasement can create a cleaner barrier around the bedding where dust mites commonly live. It suits anyone managing dust mite sensitivity, accidental spills, or a bedroom with an older mattress and box spring. The right choice depends mainly on mattress size, depth, closure design, and how the surface feels during sleep.

A Closer Look At Each Pick
This queen encasement surrounds the mattress on all six sides, creating a physical barrier around the sleeping surface. The top panel uses cotton terry, while polyester backing and a polyurethane layer provide the waterproof construction. That combination suits allergy-focused households that also want protection from perspiration, stains, or bed-wetting incidents.
Unlike a fitted protector, the zippered enclosure covers the sides and closes around the mattress. The fine zipper and sealed design are intended to keep the mattress covered on every surface. Measure your mattress first, particularly its depth, because the listed fit covers 13- to 16-inch-deep models.
A Few Highlights
- The six-sided design encloses the top, sides, and bottom rather than leaving the mattress sides exposed.
- Waterproof construction adds useful spill protection without requiring a separate plastic sheet.
- The cotton terry top gives the sleeping surface a softer feel than exposed mattress fabric.
- The fine zipper closure supports a tighter fit around the mattress.
Points To Note
- Installation takes longer than stretching a fitted protector over the mattress.
- Accurate depth measurement matters, particularly for a thick queen mattress or pillow top.

Who It Suits Best
You benefit most from this cover with a queen mattress in the stated depth range who wants full enclosure and moisture protection.
Another Choice May Suit
The Guardmax Queen Waterproof Zippered Box Spring Cover is a better fit when your priority is enclosing the box spring rather than the mattress.
A thick king mattress can leave more exposed surface than a standard pillow-top model, so the 17- to 20-inch depth range is the detail to check first. This SureGuard encasement uses the same six-sided, waterproof approach as the queen version, extending that coverage to larger beds. It works well for households seeking a bedroom-wide barrier without adding a separate mattress wrap.
Compared with the SureGuard Queen Mattress Encasement 13-16 in. Deep, the main difference is mattress size and depth rather than the basic enclosure design. The labeled hypoallergenic construction, fine zipper, and sealed closure make this a practical choice for allergy-focused sleepers with a king profile.
The Good Stuff
- Accommodates king mattresses between 17 and 20 inches deep.
- Waterproof construction handles perspiration, spills, and stains around the mattress.
- The six-sided zipper encloses more of the mattress than a fitted protector.
Worth Noting
- It will not fit a shallower king mattress outside the stated depth range.
Made For
You benefit most from this cover with a 17- to 20-inch-deep king mattress that needs waterproof enclosure.
Reach For A Different Pick When
The Guardmax Queen Mattress Cover better suits a standard queen bed where a soft knit surface matters more than deep king-profile coverage.
Protecting only the mattress leaves the box spring exposed, especially in older homes where dust, moisture, and spills can collect underneath. This Guardmax cover closes that gap with a six-sided waterproof enclosure made for a queen box spring. It is a useful companion to a mattress encasement when you want the full bed structure covered.
The zippered design makes more sense here than on a loose fitted sheet because the box spring has vertical surfaces that need enclosing. The cover is also listed for protection against dust mites, dirt, spills, and stains, giving allergy-focused households a broader defensive perimeter around the sleeping area.
Good Reasons To Consider
- Extends enclosure to an often-overlooked part of the bed.
- Waterproof construction helps shield against moisture and spills.
- The six-sided zipper covers more surface than a basic fitted cover.
- Absorbent material adds a practical layer against dirt and stains.
- It complements a separate mattress encasement in a complete bed setup.
Practical Considerations
- This covers a queen box spring rather than a queen mattress.
- You need compatible mattress and box spring covers to seal the entire bed.
Core Details
Built With In Mind
You benefit most from this cover with a queen box spring and a goal of enclosing both the mattress and its supporting structure.
Where A Sibling Pick Shines
The SureGuard Queen Mattress Encasement 13-16 in. Deep is the better match when the mattress itself is your primary coverage need.
A shallow twin mattress can be easier to enclose than a thick pillow-top model, and this cover is listed for 6- to 8-inch depths. The six-sided design, waterproof construction, and labeled hypoallergenic properties make it relevant for guest rooms, children’s rooms, and smaller beds. It creates a removable surface around the mattress rather than leaving the sides uncovered.
The tradeoff is the narrow fit range. Compared with the SureGuard Queen Mattress Encasement 13-16 in. Deep, this version suits a much lower profile and naturally travels less laundry. The fine zippered closure provides a more complete barrier than a fitted sheet, although installation takes a little more care.
What Pays Off
- Waterproof six-sided coverage suits a shallow twin mattress.
- The compact size works well in guest rooms and children’s bedrooms.
Things To Weigh
- It is intended only for twin mattresses between 6 and 8 inches deep.
- The zippered installation takes more effort than placing a fitted protector.
- It does not cover a separate box spring, so a second cover may be needed for the whole bed.
The Right Fit
You benefit most from this cover with a 6- to 8-inch-deep twin mattress in a smaller bedroom or guest space.
Look Elsewhere When
The Guardmax Premium Queen Waterproof Zippered Box Spring Cover fits better when you need queen box spring coverage rather than a compact twin mattress.
A soft surface can make a protective layer easier to live with, especially on a bed used every night. The Guardmax Queen Mattress Cover uses knitted polyester with a T-shirt-like feel and a quiet texture. That design may suit you better than a crisp cotton surface or a plastic-like waterproof layer, depending on your sensitivity to fabric sounds and textures.
The nylon zipper runs around three sides and tucks beneath a stitched guard flap, leaving no open corner at the pull. Unlike the taller SureGuard encasements, this cover emphasizes a streamlined queen fit and soft knit face. It is a sensible choice for reducing direct mattress contact while keeping the sleeping surface comfortable.
Everyday Perks
- The knitted polyester face feels softer and quieter than many plastic-style covers.
- A three-sided zipper with a guard flap reduces exposed closure gaps.
- The smooth knit surface stays comfortable for nightly contact.
- The queen size works well for common adult bed frames.
Possible Compromises
- Confirm the mattress depth and fit before purchase, especially with a pillow top.
- Its listing does not identify it as a dust mite encasement, so check your specific enclosure needs.

Who Should Grab It
You benefit most from this cover with a queen mattress and a preference for a quiet, soft knit sleeping surface.
Consider Something Else When
The Voyantek King Tencel Protector suits a king bed and anyone who values a smoother plant-based fiber surface.
Tencel lyocell is a cellulose fiber made from wood pulp, and this king protector places that smooth material against the sleep surface. It offers a breathable, low-noise alternative to traditional vinyl protectors, which can feel stiff or crinkly. For you, that texture may matter as much as waterproof coverage during long nights.
A TPU layer, or thermoplastic polyurethane, supplies the waterproof barrier beneath the Tencel surface. Compared with the Guardmax Queen Mattress Cover’s knitted polyester, this option offers a smoother feel and a different fiber profile. The trade-off is that it is listed as a mattress protector rather than a fully zippered encasement, so your allergy-related coverage requirements deserve a closer look.
Notable Upsides
- Tencel lyocell creates a smooth, skin-friendly contact surface.
- The breathable material helps you avoid the heavier feel associated with vinyl.
- The quiet surface reduces the crinkling common to conventional plastic protectors.
- TPU construction adds waterproof and stain-resistant coverage.
- The king size suits larger beds and shared sleeping spaces.
Less Ideal Details
- It is a protector rather than a specified six-sided zippered encasement.
- Confirm the fit and depth for your king mattress before ordering.
Quick Facts
Whose Shelf It Belongs On
You benefit most from this protector with a king mattress and a sensitivity to stiff, noisy, or overly warm vinyl surfaces.
Swap It Out When
The Guardmax Queen Mattress Cover is a better fit for a queen bed where a fully zipped closure takes priority over a Tencel surface.
What To Look For Before You Cover Your Mattress
Start With Full Enclosure
An encasement wraps around the top, sides, and bottom of a mattress. That full coverage matters when your main concern is containing dust mites within the bedding or creating a removable surface that can be cleaned. A fitted protector mainly covers the top, so it may leave more of the mattress exposed.
Match Size and Depth
A cover can look like the right size but fail to fit a deeply padded mattress. Measure both the width and the distance from the top seam to the bottom before ordering. Pay particular attention to pillow tops and raised edges, since they can add several inches to the profile.
Compare Surface and Closure
Cotton terry offers a familiar absorbent feel, while knitted polyester tends to be quiet and soft. Tencel provides a smoother, breathable alternative to vinyl. The closure also matters: a fine zipper and guard flap create a more continuous seal than an open fitted-sheet edge, especially for bed bug concerns.
Consider the Entire Bed
A mattress encasement cannot cover an exposed box spring. Homes with older bedding systems or visible fabric around the frame may need a matching box spring cover as well. This is especially helpful in guest rooms, rental properties, and bedrooms where you want one removable barrier for each major sleeping surface.
What Sets These Covers Apart
Common Shopping Slip Ups
The easiest mistake is buying by mattress size while ignoring depth. Another is choosing a top protector when you need full six-sided enclosure. Check the closure, surface feel, and whether a separate box spring cover is needed before purchase.
What Separates Premium From Basic
A higher-tier option often adds deeper waterproof construction, a full enclosure, or a softer surface material. The upgrade pays off when spills, frequent laundering, or skin sensitivity matter more than the simplest possible cover.
Frequently Asked Questions
Do mattress encasements help with dust mite allergies?
A mattress encasement creates a barrier around the sleeping surface where dust mites commonly live. It works best alongside regular bedding care, good ventilation, and humidity management.
What is the difference between a mattress protector and an encasement?
A protector usually fits over the top and sides of a mattress. An encasement wraps around all six sides, including the bottom, for more complete coverage.
Should I cover the box spring too?
Covering the box spring gives you a more complete barrier around the bed. It is especially useful for older mattresses, visible box spring fabric, or bedrooms with allergy-related dust concerns.
How often should I wash a mattress cover?
Follow the care instructions for the specific material and wash it whenever your household routine allows. Keeping removable bedding clean supports the enclosure’s role as a protective layer.
Which surface feels best for sensitive skin?
Tencel offers a smooth, breathable alternative to vinyl, while cotton terry provides a familiar absorbent feel. Knitted polyester is another quiet option for people who dislike the crinkle of plastic-style protectors.
Final Verdict
The right mattress cover depends on fit, enclosure, and comfort rather than a universal choice. SureGuard leads with deep six-sided waterproof coverage, Guardmax provides box spring and soft knit options, and Voyantek suits king sleepers who prefer Tencel. Measure your mattress, cover the full bed structure, and choose the surface you will be comfortable touching every night.
