A zippered mattress encasement is designed to cover all sides of a mattress and help seal it off from bed bugs. The SureGuard is best for shoppers who want a stated bed bug sealing system and waterproof coverage; the Utopia Bedding 12-inch model suits standard-depth queen mattresses. The two-pack is useful for covering more than one mattress, while the Hospitology model fits a wider range of mattress depths. Guardmax emphasizes a guarded zipper and washable, quiet fabric.

SureGuard Waterproof Mattress Encasement

This six-sided queen encasement is best for shoppers who need both bed bug-focused zipper features and waterproof protection. Its listed fit is for mattresses 13 to 16 inches deep.
The top is cotton terry, while the other five sides use polyester backing and polyurethane. The manufacturer describes the cover as waterproof and identifies a super-fine zipper, Invisi-Zip, and SureSeal technology as features intended to seal the mattress. It also lists a 10-year quality guarantee.
Choose this if your queen mattress falls within the stated depth range and you want a waterproof surface. The product information recommends pairing it with a SureGuard box spring encasement. For frequent accidents, it suggests adding a fitted protector over the encasement.
Utopia Bedding 12-Inch Queen Encasement

This Utopia Bedding model is best for a standard queen mattress measuring 60 by 80 inches and 12 inches deep. Its listed features include a zippered closure designed to help keep bed bugs and dust mites away from the mattress.
The smooth knitted fabric is described as breathable, soft, and quiet. Those details may matter to buyers who want an encasement that feels less stiff or noisy during sleep.
Choose this if your mattress matches the listed dimensions and you want a simple zippered, full encasement. Its stated pocket depth is 12 inches, so it may not be the right fit for a thicker mattress.
Utopia Bedding Queen Zippered 2-Pack

This two-pack is best for buyers who need covers for two queen mattresses or want a second encasement available. Each cover is listed for a 60-by-80-inch mattress up to 15 inches deep, with 360-degree coverage.
The stretchy knitted polyester fabric is described as soft and non-crinkling. A wrap-around zipper encloses the mattress, and the product information says the cover is designed to stay in place without shifting.
Choose this if you need two covers and your mattresses are no deeper than 15 inches. The supplied information describes waterproof protection but does not specify zipper-sealing technologies, so compare those details if that is your main priority.
Hospitology Sleep Defense Queen Encasement

This Hospitology encasement is best for queen mattresses with a depth between 12 and 18 inches. Its stretchable construction is listed as fitting standard 60-by-80-inch mattresses within that range.
The cover has a polyester face and polyurethane lining. The product name identifies it as a zippered bed bug and dust mite encasement, and its features also describe it as waterproof and hypoallergenic.
Choose this if your mattress is thicker than 12 inches but no more than 18 inches deep. Confirm the actual mattress dimensions before ordering; the provided information does not detail a special zipper guard or sealing system.
Guardmax Queen Mattress Encasement

Guardmax is best for shoppers looking for a six-sided cover with a zipper that closes around three sides and tucks under a stitched guard flap. The feature description says the flap covers the zipper pull area to avoid an open corner or gap.
A waterproof layer beneath the knitted polyester face is intended to protect the mattress from sweat, spills, and wet nights. The fabric is described as soft and quiet, and the listed care details include warm washing and low tumble drying.
Choose this if the guarded zipper and washable fabric suit your needs. The supplied product details do not state a mattress-depth range, so check the product listing for fit measurements before purchasing.
Buying Guide: How to Choose a Bed Bug Mattress Encasement
What size and depth should you check?
Measure the mattress width, length, and depth, including any pillow top. For a queen, the products here generally list a 60-by-80-inch footprint, but their depth limits differ. The Utopia 12-inch model is for 12-inch mattresses; the two-pack fits up to 15 inches; SureGuard fits 13 to 16 inches; and Hospitology covers 12 to 18 inches. Verify that the cover fully fits before buying.
Which zipper details matter?
Look for a zippered design that encloses the mattress on all sides. Some listings provide additional details: SureGuard names Invisi-Zip and SureSeal, while Guardmax describes a stitched guard flap over the zipper pull. Compare the actual closure features rather than assuming every zippered protector uses the same sealing design.
Do you need waterproof protection?
If spills or nighttime accidents are a concern, prioritize a product whose listed features explicitly say waterproof. SureGuard, Hospitology, the Utopia two-pack, and Guardmax include waterproof claims in the supplied product information. Consider fabric feel and care instructions too, especially if the cover will be used daily.
Does a mattress encasement cover the box spring?
A mattress encasement covers the mattress, not automatically the box spring. SureGuard’s product information specifically recommends using a separate SureGuard box spring encasement. Check whether other bed components need their own covers.
Frequently Asked Questions
What is a bed bug proof mattress encasement?
It is a cover designed to enclose a mattress on all sides with a zipper. Product-specific closure features vary, so review the zipper and fit details before choosing one.
Can an encasement be used on a thick mattress?
Yes, if its listed depth range accommodates the mattress. Among these options, Hospitology lists a range of 12 to 18 inches, while SureGuard lists 13 to 16 inches.
Is a mattress encasement the same as a fitted protector?
No. An encasement surrounds the mattress, while a fitted protector generally covers the sleeping surface and sides. SureGuard recommends an additional fitted protector for easier cleanup after frequent accidents.
Should I encase the box spring too?
If you want coverage for the box spring, check for a separate box spring encasement. A mattress cover alone does not cover that separate component.
