Full XL (17-20 in) SureGuard Mattress Encasement - Waterproof, Bed Bug

In this review of the Full XL SureGuard Mattress Encasement the bottom line is simple: this is a protective, six-sided cover best suited for sleepers who need long-lasting waterproofing and a sealed barrier against allergens and bed bugs. The reviewer found the product most valuable for families, allergy sufferers, and anyone wanting a near-permanent mattress shield that retains mattress feel. The combination of a 100% cotton terry top and a fully sealed zipper system makes it a practical choice when the primary concern is protection rather than temporary convenience.

Key Features

• 100% Waterproof: The six-sided premium barrier blocks perspiration, bed wetting, liquids and stains to protect the mattress from moisture damage.
• Bed Bug Proof: A super fine zipper with Invisi-Zip and SureSeal technology completely seals the mattress against bed bugs when used with a separate box spring encasement.
• Soft & Noiseless: The 100% cotton terry top wicks away moisture and keeps the original feel of the mattress without the crinkly noise of vinyl.
• Hypoallergenic Protection: The encasement blocks dust, dirt and dander on all sides to help reduce allergen exposure for sensitive sleepers.
• Durable and Certified: Independently lab tested and GREENGUARD Gold certified, and backed by a 10-year quality guarantee for long-term use.
• Deep Fit: Sized Full XL at 54 in x 80 in to fit mattresses 17 to 20 in deep and closes with a full zipper for complete coverage.

Who It's For

The Full XL SureGuard Encasement is ideal for households with young children, pets, or anyone who wants a long-term solution to spills and stains without sacrificing mattress feel. It also works well for allergy sufferers who need a sealed fabric barrier against dust and dander on all sides, and for those looking for a noiseless cotton surface rather than a synthetic cover.

Those who should look elsewhere include people who want frequent easy removal for nightly laundering as the encasement is intended as a semi-permanent wrap; for frequent accidents the maker advises using a fitted protector over the encasement. Also, customers who place the highest priority on a heavy-duty industrial zipper may want to compare zipper designs, since feedback on zipper quality is mixed.
