I answered this with my mattress pad, but I will say again, you should always en lose your mattress, especially if so.done else has shared it, with a totally enclosed hypoallergenic, bed bug free, dust mites free, allergen free mattress cover & that is why I did a lot of research & did not just buy the cheapest one I found. Some are thin plastic and rip when you move in bed as well as the fact that the plastic makes you sweat! I will review this product again in 30 days and co firm my research, but I do believe it will be the same! Beverly of St Charles MO
