Cal King SureGuard Mattress Encasement - 100% Waterproof, Bed Bug

In this review the Cal King SureGuard Mattress Encasement is evaluated for people who need total mattress protection without changing the feel of their bed. The bottom line: this six-sided, zippered cover is best for households worried about liquids, allergens and bed bugs because it provides a full seal and a cotton terry surface that stays quiet and comfortable. The review finds it an especially practical choice where longevity and easy care matter, and notes the company backs it with a 10-year quality guarantee.

Key Features

• 100% Waterproof: The six-sided construction blocks perspiration, bed wetting and spills to protect mattress layers from stains and moisture damage.
• Bed Bug Proof: A super fine zipper with Invisi-Zip and SureSeal technology fully seals the mattress, preventing bed bugs from entering or escaping through seams.
• Soft and Noiseless: A 100% cotton terry top preserves the natural feel of the mattress while wicking away moisture without the crinkly noise of vinyl alternatives.
• Hypoallergenic Protection: The encasement blocks dust, dirt and dander on all sides, helping reduce allergen exposure for sensitive sleepers.
• Machine Washable: The zippered, six-sided design is designed for machine wash and dry, simplifying periodic cleaning and maintenance.
• Certified Safety: Independently lab tested and GREENGUARD Gold certified, indicating low chemical emissions for indoor air quality.

Who It's For

This encasement is for owners of Cal King mattresses that are 6 to 8 in deep who want a comprehensive, six-sided barrier against liquids, allergens and bed bugs while keeping the mattress feel intact. It suits families with children, pet owners, allergy sufferers and anyone who wants long-term mattress protection backed by a 10-year quality guarantee.

It is less necessary for people who already use both a fitted waterproof protector and a separate encasement or for those who prefer a thin, non-zipper protectant that can be removed nightly. Also, shoppers seeking extra-deep compatibility should confirm pocket depth before buying, since this model fits mattresses 6-8 in deep.

Cons
