Did you know that every bed needs a Protect-A-Bed Pillow Protector? FACT: Every night the human body loses a liter of body fluids through the skin pores and mouth, as well as millions of skin flakes. Unprotected mattresses thereby create the perfect breeding ground for bacteria and dust mites (a major cause of asthma, eczema and rhinitis). You can control this by fitting a Protect-A-Bed AllerZip Mattress Protector, which is also especially helpful in cases of incontinence. This waterproof pillow protector zippers to secure in place and its cotton, terry-cloth fabric toplayer is soft and comfortable to sleep on. Guaranteed against leaks or tears for 10 years or the factory will replace at no cost. (Queen Pillow Size: 21x31 in.) Wash before use for best results. Do not bleach or dry clean. This AllerZip pillow protector is also guaranteed bed bug entry, escape and bit proof. There are two pillow protectors in this pack.
