I have to tell you, this is such an eye, ear and nose allergy saver for me. I am always dealing with having the need to vacuum the mattress because my old mattress was not protected from allergens but my new mattress is now provided protection by using this cover and I'm not sniffing or sneezing anymore. Thank you! It's nice to get up refreshed and ready to go and not feeling the need to grab the humidifier and a Benadryl..haha!
