Guardmax Jersey Knitted Full XL Zippered Mattress Encasement

In this review of the Guardmax Jersey Knitted Full XL Zippered Mattress Encasement the bottom line is simple: this cover is for sleepers who need full containment and quiet comfort. It is best for anyone wanting a truly waterproof, fully sealed encasement that still feels soft to the touch. The product stands out because it combines a TPU laminate membrane for liquid protection with a jersey knitted polyester surface so the mattress does not feel plasticky. For people prioritizing bed bug protection and a hotel-like feel, this encasement delivers.

Key Features

• Full XL fit: Designed for a Full XL mattress 54 x 80 x 12 in and stretches to fit depths up to 13 in, so it accommodates most extra-thick mattresses.
• Jersey knitted comfort: The outer jersey knitted polyester creates a soft, breathable sleeping surface that avoids the crinkly sound of traditional vinyl covers.
• 100% waterproof membrane: A TPU laminate prevents liquid spills, urine, and other moisture from penetrating the mattress, protecting it from stains and odors.
• Bed bug proof seal: The full enclosure with a nylon coil zipper is made in an EPA registered facility to ensure containment and to keep pests out once sealed.
• Durable zippered closure: The nylon coil zipper is designed to reduce snags and failure compared with lower quality zippers and allows easy installation and removal.
• Hypoallergenic protection: The encasement blocks dust, dirt, and dander to help reduce allergy triggers during sleep.

Who It's For

This encasement is ideal for people who need complete mattress protection: those dealing with bed bugs, households with children or pets that cause liquid accidents, and allergy sufferers seeking a barrier against dust mites and dander. It also suits sleepers who dislike noisy, plastic-feeling protectors and want a softer, jersey surface.

It may be less appropriate for shoppers who want a fitted pad rather than a full encasement (this covers the entire mattress). Also, users who prioritize an ultra-rugged industrial zipper should consider that some customers reported mixed experiences with zipper longevity, so extra care when zipping is advisable.

Pros & Cons

Pros

• Soft, breathable jersey knit surface avoids the plasticky feel and remains quiet during use.
• Complete waterproof protection from a TPU laminate keeps liquids from reaching the mattress.
• Full encasement with a nylon coil zipper provides true bed bug proofing when sealed.
• Hypoallergenic barrier reduces dust mite and dander exposure for sensitive sleepers.

Cons

• Some customers report mixed zipper durability, so the zipper may require gentle handling.
• Full encasement requires lifting the mattress to install, which can be awkward without help on heavier beds.
