SureGuard Cal King Mattress Encasement – 100% Waterproof, Bed Bug Proof, Hypoallergenic

All-in-one protection for your Cal King mattress

The SureGuard Cal King Mattress Encasement is a six-sided, zippered cover designed to wrap your mattress in durable, comfortable protection. Sized at 72 x 84 inches and compatible with mattresses that are 17 to 20 inches deep, it surrounds the bed with a seamless barrier and a soft, sleep-friendly touch.

Key protection you can feel

• 100% Waterproof — blocks perspiration, spills, and accidents from seeping into the mattress with a long-lasting, six-sided shield. Includes a 10-year quality guarantee.
• Bed Bug Proof — Invisi-Zip and SureSeal technology fully seal the mattress when used with a compatible Box Spring Encasement, helping deter nighttime intruders.
• Keeps your mattress clean & fresh — blocks dust, dirt, and dander from all sides for a consistently tidy sleeping surface.

Comfort and safety without compromise

• Soft & Noiseless — 100% cotton terry top delivers a gentle touch, wicks away moisture, and preserves the natural feel of your mattress.
• Hypoallergenic & toxin-free — designed without vinyl, PVC, phthalates, or harsh additives for a calmer sleep surface.

Care, testing, and practical use

Machine wash and dry for easy upkeep. The encasement is independently lab tested and GREENGUARD Gold certified, reflecting a commitment to safer indoor air quality.

Design, fit, and setup tips

Six-sided construction provides full coverage around the mattress edges for consistent protection. The Cal King size (72 x 84 inches) fits mattresses 17–20 inches deep, and the six-sided zipper enables easy on/off. For frequent accidents and easier cleanups, place a fitted SureGuard Mattress Protector over the encasement during laundering or everyday use.

Real-life scenarios

Whether you’re managing spills, pet messes, or seasonal allergies, this encasement aims to keep the sleep surface comfortable and clean. The combination of a soft top layer and a durable barrier helps maintain a fresh feel night after night without changing the mattress’s core comfort.
