Protect-A-Bed AllerZip Mattress Encasement review

Protect-A-Bed makes the protectors that many hotels and pest control professionals use, and its AllerZip encasement is the pick for total coverage. Instead of covering only the sleeping surface, it zips around all six sides of the mattress and closes with the brand's patented Bug Lock zipper, which Protect-A-Bed says makes it bite, entry and escape proof for bed bugs. The company rates it dust mite proof on all six sides and allergen resistant, and every product uses a LiquiDry waterproof layer and FUZE antimicrobial treatment under a soft, quiet fabric surface. It fits mattresses 6 to 18 inches deep and can be washed in hot water at 130 F. The AllerZip encasement started at $79.99 on Protect-A-Bed's US store when we checked, and the brand offers 100-night returns. For people who only need spill protection, the brand's Essential protector or SafeRest is easier to put on, since an encasement has to be zipped around a lifted mattress.
