I bought this mattress for my cousins. They are about to have a baby. The reason I purchased this mattress is because I love it. My daughter has this mattress in a full. When considering this purchase it was a must to have the cleanest materials used in the mattress - Naturepedic has received the best ratings, even some extremely hard ones to get - but I loved that one side was waterproof and the other side is quilted. Every once in a while my daughter will have an accident at night. All I have to do is strip off the sheets, wipe the waterproof side down with some soap and water, make the bed, and put her back to sleep. When she is a bit older we will flip it over for her to enjoy the quilted side. Not only does she sleep really well on this mattress, but so do I knowing that she is not being exposed to toxic chemicals from her bed. Thanks Naturepedic!
