I had my doubt when we first recieved this - as my husband does wake up most mornings with slight allergies. Well, after only about a week - he hasnt had one flare up and is fully convinced that this is the answer. It was super easy to put over the mattress myself too. It is a bit rattly sounding as if we were going to be laying on plastic - but it doesnt make much difference once the actual sheets are over the cover. I do recommend this if you have problems - it is definately worth a try and see if it helps you too!
