The AllerEase Cotton Fresh line is the avenue of clean and comfortable. Made from 100% cotton, waterproof top fabric provides both softness and protection from spills and stains. The HeiQ Fresh finish inhibits the growth of odor-causing bacteria while the allergen barrier blocks unhealthy household allergens like dust mites, pollen, and pet dander from collecting in your mattress. Backed by AllerEase's Lifetime warranty, this zippered protector is bedbug bite-proof and machine washable for easy care.
