Guardmax Jersey Knitted King Zippered Mattress Encasement - Waterproof

In this review of the Guardmax Jersey Knitted King Zippered Mattress Encasement the bottom line is simple: it is for sleepers who want full, noiseless protection without feeling like they are sleeping on plastic. The single biggest reason to buy is the combination of a soft, breathable jersey knitted surface with a TPU laminate that delivers truly 100% waterproof protection. For anyone needing bed bug proofing and allergy defense on a standard King mattress up to 13 in deep, this encasement balances comfort and full enclosure protection.

Key Features

• Size & Depth: Fits a King mattress 78 x 80 x 12 and stretches to accommodate mattresses up to 13 in deep, making it suitable for most modern mattresses.
• Jersey Knitted Surface: The soft polyester knit provides a comfortable, hotel-like feeling and avoids the plasticky sound or stiffness of some encasements.
• TPU Laminate: A thin waterproof membrane blocks all liquids so spills or urine will not reach the mattress core.
• Zippered Encasement: A full nylon coil zipper seals the mattress completely to prevent bed bugs from entering or escaping once closed.
• Hypoallergenic Barrier: Protects against dust, dirt and dander, helping allergy sufferers sleep without nighttime sneezing.
• Easy Care: Simple to install and remove for washing; can be handwashed or laundered on a quick cycle.

Who It's For

This encasement is ideal for people who want full mattress enclosure with a comfortable sleeping surface: those dealing with allergy concerns, households with children or pets where spills are likely, and anyone seeking bed bug proofing backed by manufacturing controls. The soft jersey finish is a good choice for anyone sensitive to noise or the waxy feel of some waterproof covers.

Consumers who prefer a fitted, mattress-pad style protector rather than a full zippered encasement should look elsewhere, as should users who need a heavy duty textile finish beyond jersey knit for decorative purposes. Also, if zipper durability is a top priority for you, note that some users reported mixed experiences with zipper longevity.
