Full 9-12 in SureGuard Mattress Encasement - Waterproof Bed Bug Proof

In this review the Full 9-12 in SureGuard Mattress Encasement is assessed for people who need a complete, long-lasting barrier around their mattress. The single biggest reason to consider it is its six-sided, 100% waterproof zipper design that seals the mattress from liquids and pests while keeping the mattress surface soft to the touch. The review focuses on real-world use: how it fits a 9 to 12 in mattress, how the cotton terry top feels against bedding, and whether the Invisi-Zip and SureSeal zipper system performs as promised for bed bug protection.

Key Features

• Six-sided protection: Fully encloses the mattress to block perspiration, spills and stains on all surfaces for comprehensive protection.
• 100% waterproof: A impermeable barrier prevents liquids reaching the mattress core, helping preserve mattress hygiene and warranty coverage.
• Bed bug sealing: The super fine zipper with Invisi-Zip and SureSeal technology creates a continuous seal to prevent bed bugs from entering or exiting the mattress interior.
• Soft cotton terry top: The 100% cotton terry surface wicks moisture and keeps the original mattress feel intact while remaining quiet during movement.
• Easy care and fit: Designed for Full size 54 in x 75 in mattresses that are 9 to 12 in deep and is machine washable for routine cleaning.
• Certified and guaranteed: Independently lab tested, GREENGUARD Gold certified, and backed by a 10-year quality guarantee for long-term use.

Who It's For

The encasement suits homeowners and renters who want full perimeter protection for a Full mattress and need both liquid resistance and pest control in one product. It is especially useful for families with occasional bed wetting, people caring for someone with incontinence, or anyone who wants to guard an investment mattress from dust, dirt and stains.

Shoppers who prefer a thinner, lightweight mattress pad rather than a full zipper encasement, or those with mattresses thicker than 12 in, should look at alternative protector styles. Also, customers who expect zipper hardware to be impervious to wear should note that some users report mixed experiences with zipper durability.
