Twin Size Jersey Knitted Zippered Mattress Encasement - Waterproof

In this review of the Twin Size Jersey Knitted Zippered Mattress Encasement, the bottom line is simple: it is for sleepers who want full protection without the crinkly, plastic feel of many protectors. The single biggest reason to buy is the combination of a soft, jersey knit surface with a TPU laminate that makes the cover fully waterproof while remaining breathable. The encasement fits a 39 x 75 x 10 in mattress and stretches to cover depths up to 11 in, so it works well for most twin mattresses including slightly thicker toppers.

Key Features

• Jersey knitted surface: The polyester knit delivers a soft, hotel-like feel that stays comfortable through the night and avoids the plasticky noise of some protectors.
• Fully waterproof TPU laminate: A membrane layer blocks all liquids so spills or accidents will not penetrate the mattress beneath.
• Full zipper encasement: A nylon coil zipper seals the mattress completely to keep dust, dust mites and bed bugs out once fully closed.
• Stretch fit for depth: Designed for twin mattresses 39 x 75 x 10 in and stretches to fit up to 11 in depth for snug coverage.
• Hypoallergenic protection: The cover reduces exposure to dust, dander and allergens so allergy-prone sleepers can breathe easier.
• Machine friendly care: Easy to wash by hand or in a quick machine load to remove stains and debris without special treatment.

Who It's For

This encasement is a good match for someone who needs complete mattress protection but does not want to sacrifice comfort: parents of young children, allergy sufferers, or anyone seeking bed bug-proofing from an encasement made in an EPA registered facility. The soft jersey face makes it suitable for everyday use on a primary bed or guest bed where comfort matters.

Those looking for fitted mattress pads with thick quilting or additional temperature regulation should look elsewhere, as this product focuses on barrier protection rather than added cushioning or cooling technologies. Shoppers who require a non-zippered fitted protector for easier on/off changes may prefer a different style.
