As we sleep we shed thousands of dead skin cells, which can quickly accumulate providing an ideal environment for allergens to thrive. SafeRest mattress protectors trap allergens and skin cells on the surface of the protector where they can be easily washed away during suggested quarterly launderings. This helps provide a cleaner more allergen free sleep environment for you and your family.
