PureCare's clinically proven 5-Sided mattress covers fit like a fitted sheet around your mattress, providing a physical barrier against allergens, dust mites, stains, moisture, mold and mildew. Our OmniGuard® Advance lightweight performance fabric is approved for all mattress types and won't alter the feel or comfort of your mattress. Completely washable, our 5-Sided protectors are specially designed so that you can wash and dry on hot settings for optimal sanitization. PureCare's mattress protectors are treated with antimicrobial silver chloride that inhibits bacteria, mold and mildew that causes deterioration, stains and odors on this product, allowing you to create a cleaner sleep environment in every bedroom in your home. Additionally, our clinically proven protectors are the official mattress protectors of both the National Sleep Foundation and the Women's Choice Award.
