Mattress Encasement Zippered California King - Waterproof Sleep

In this review of the Mattress Encasement Zippered California King, the bottom line is simple: it is a practical choice for sleepers who want reliable protection without sacrificing comfort. The encasement is designed to fully cover a California King mattress and provides a 100% waterproof barrier around all six sides while using an extra-soft polyester knit that remains breathable. For anyone worried about bed bugs, dust mites, spills or allergens, this product earns high marks for fit, ease of use and long-term durability.

Key Features

• Zippered full encasement: A secure zipper closure seals the mattress to prevent bed bugs and dust mites from reaching the sleeper for long-term protection.
• Waterproof on six sides: Lab-tested waterproof membrane covers the entire mattress surface and sides to stop liquid from penetrating and damaging the mattress.
• Stretchable polyester knit: The extra-soft fabric stretches to fit standard California King sizes and stays comfortable under sheets without feeling plastic-like.
• Breathable construction: The breathable waterproof membrane is designed not to trap heat so it helps preserve a cooler sleeping surface compared with non-breathable covers.
• Easy care and coverage: Machine washable and tumble dry low so the encasement is simple to maintain and comes with a 5-year limited manufacturers warranty for added peace of mind.

Who It's For

This encasement is ideal for people who own a California King mattress and need full protection from pests, allergens or spills. It suits allergy sufferers, families with children, or anyone in shared housing who wants to block bed bugs and dust mites. The soft polyester face makes it a good match for those who prioritize comfort as well as protection.

People who prefer ultra-plush mattress toppers that dramatically change feel, or who need a cover for a mattress deeper than the product's stretch range, should consider other options. Also, those who want a fitted-sheet style protector rather than a full encasement should look elsewhere.
