The AllergyCare Cotton Zippered Mattress Encasement is a six-sided, zippered cover made of 100% cotton with a fine 4.59-micron weave. It blocks dust mites, pet dander and bed bugs without a synthetic membrane or chemical finish, and the patented BugStop Seal is designed to keep bed bugs from escaping or getting in. The 9-inch depth suits low-profile mattresses, and the long twin size fits 39 x 80 inch beds such as dorm and adjustable-base mattresses. Against polyester and vinyl encasements it breathes better and feels more like fabric, but cotton is not waterproof and the shallow depth limits it to thinner mattresses.
