A zippered mattress protector that fully encases your mattress is essential to keeping your mattress completely protected; however, they can be a chore to take on and off. This is why AllerEase developed a truly unique mattress protector that features a removeable, zip-off top cover that easily zips on and off in between washings. The AllerEase Platinum Zip-Off Top Mattress Protector was made for those who want full protection for their mattress with the added convenience of a simple zip-off top. With allergy protection & luxurious plush top layer this protector is designed for ultimate comfort. The allergen barrier top layer prevents dust mite matter and other non-living allergens from collecting in the mattress protector over time. The waterproof protection provides protection against urine, water, spills and stains.
