Protect-A-Bed Essential Mattress Encasement review

The Essential encasement is the sensible Protect-A-Bed choice for thinner mattresses. It shares the six-sided, zip-around design and patented Bug Lock closure that the company rates as bite, entry and escape proof, so the bed bug barrier is the core of the product rather than an add-on. What you give up against AllerZip is depth: Protect-A-Bed lists it for mattresses 6 to 11 inches deep, against 6 to 18 inches for AllerZip. For a dorm twin, a guest bed, a bunk or a basic innerspring in a rental, that is a fair trade. It was listed at $64.99 when we checked, and the matching Essential Box Spring Encasement was $59.99, which makes a full bed set easy to buy in one order. Returns run 100 nights, and shipping is free over $99.
