I really did use it for a week to see how it fit my bed and I must say it does stays and fit securely. It is actually a waterproof and I love it. The fabric is definitely soft and cool which makes it more comfy to sleep on. I like the upper area where has the pattern it feels like they put some foam in it or is it just me cuz it feels like it. It is not so heavy which is a plus. I don't like so heavy mattress pad cuz it sucks when washing them. I would really recommend this product.
