This projector is surprisingly very soft and feels comfortable, but the sense of thickness gives it a soft feel. Although it has vinyl/plastic on the bottom so it's not waterproof, it's literally silent on the bed. My worst fear was that it would be noisy while driving and also in the heat which is not noisy at all almost nothing is kept inside in the heat. It feels like there is no mattress topper. I know it's amazing how surprised I was, but it actually works very well and is very waterproof. We are actually planning to buy three more for our children's three single beds.
