Many of the Sealy® mattress and pillow covers are treated to be dust-mite resistant. Sealy® mattresses are produced from 100% new materials and we place the utmost emphasis on product quality and consistency by following a variety of industry standards and conducting proprietary tests to ensure that our products adhere to all local, state, and federal health regulations.
If the mites are actually bed bugs, or an insect similar, they are an insect like a housefly and can be easily introduced into any household environment and make their home in or on almost any surface or household item: carpeting, clothes, etc. Unfortunately, there is very little within the average household that is completely resistant to bed bugs. As a company, we cannot do much for a mattress that has been exposed to mites or bugs. We suggest reaching out to your local pest controller to have the insects identified and see what the best option is to rid your home and mattress of the insects.
