Cal King 13-16 in SureGuard Mattress Encasement - Waterproof Bed Bug

In this review of the Cal King 13-16 in SureGuard Mattress Encasement, the bottom line is straightforward: this is a practical choice for anyone who needs full mattress protection without changing the feel of their bed. The reviewer found the six-sided, zippered design most valuable because it creates a complete barrier against liquids, dust and bed bugs while retaining mattress comfort thanks to the 100% cotton terry top. For households with children, pets or allergy sufferers this encasement is primarily about long-term mattress preservation and peace of mind.

Key Features

• 100% Waterproof: The six-sided premium construction blocks perspiration, spills and stains to keep the mattress surface dry and protected.
• Bed Bug Proof: A super fine zipper with Invisi-Zip and SureSeal technology fully seals the mattress to reduce the risk of bed bug ingress when used with a box spring encasement.
• Soft & Noiseless: The cotton terry top feels like fabric, wicks away moisture and preserves the original mattress feel without the crackle of vinyl.
• Hypoallergenic Barrier: Blocks dust, dirt and dander on all six sides, helping to reduce allergens that reach the sleeping surface.
• Durable and Tested: Machine washable, GREENGUARD Gold certified and backed by a 10-year quality guarantee for long-term use.

Who It's For

This encasement is best for Cal King mattress owners with a depth between 13 and 16 in who want full perimeter protection. It suits parents dealing with occasional bed wetting, pet owners worried about accidents, and allergy sufferers who need a barrier against dust and dander.

Those who prefer a very thin fitted protector only for liquid cleanup or who want a cheaper short-term option might look elsewhere; the encasement is designed for full isolation and long-term protection rather than quick on/off daily use.

Pros & Cons

• GREENGUARD Gold certification and no PVC or phthalates make it a safer chemical choice.

Cons
