CleanRest convertible mattress pads with MicronOne® fabric technology help to ensure that you'll have a healthy, allergen-free night's sleep. MicronOne® fabric creates a protective barrier between you and allergens that can negatively affect your sleep and it blocks all micro-toxins larger than one micron in size, including dust mites, mold spores, pollen, pet dander and bed bugs from coming into contact with you. The two-piece design provides for easy installation and cleanups, allowing you to wash and reuse your mattress pads for years. The soft, padded top piece delivers an added layer of comfort, while the bottom piece provides complete protection from bed bugs and dust mites. The CleanRest convertible mattress pads with MicronOne® fabric technology are a great solution for your allergen-free bedding needs.
