I  bought this mattress cover because I have allergy induced asthma, and it can get serious quickly. So I am doing all that I can to keep common allergens down in my house. When I found out how many allergens can get trapped in a mattress, especially an older mattress like mine I was appalled. And now I understand why I have a runny nose when I wake up.  I really like the ease of putting this cover on my bed.  Its soft and smooth and goes on easy.  Then it zips up, easy as can be. It's washable and it doesn't feel hot at night, which is really important. And using this cover and keeping down mold and dust in my room has really helped my sinuses. I would definitely recommend this to my friends!
