I had to replace a 40 year old pillow protector. **** had one, but it turned in a dummy pillow when I clicked on it. Now I realize you have to use "pillow protector" as the search word, but it still isn't dust mite proof. This pillow I was protecting is one of those old pillows made of cotton that feels like wool. It feels like sleeping on a cloud rather than a noisy hospital pillow. Thanks to Great Offer Stock my favorite pillow is saved.
