It's such a great feeling knowing I finally can get the quality nights sleep I deserve.Thanks to my new Allerease Zippered Pillow Protector I no longer have to worry about my allergies keeping me awake.My jumbo pillow cover was easy to install,it opens at one end to easily slide your pillow in.The top has a zipper function to properly seal your encasement.What I love best is the soft silky comfort feel of the case which is unlike most of the ones I've tried.This case works to seal out pet dander,dust mites,pollen,and bed bugs.Fits any standard pillow with some added room space.
