Query: Protects the mattress and is comfortable too!

I wish I had known about this product sooner all of the mattresses in my house would have had them and the occasional "accidents" the kids had would not have been a worry. We started with one on our Memory foam mattress and we both think it's great. It feels great to know there are no dust mites "living" in the mattress! Just pop it in the washer every other week or so; have had it over a year and it's holding up well.
