The need to have a good mattress pad is always forgotten!  I purchased this mattress pad because, I just bought a new memory foam mattress, we live near the coast and the house doesn't have AC and I am a hot sleeper and tend to sweat at night and needed the waterproof to protect the mattress. My wife has allergies and so the hypoallergenic portion is a bonus for her, so bottom line is that we both win!!
