I'm so happy with this purchase!  Our new mattress warranty states we need it to be covered and the cover should be waterproof to keep the warranty valid. Most mattress covers that are waterproof make a crinkle noise and are warmer because of the vinyl.  So far I'm not unhappy, it has a decent pad over the waterproof part so it doesn't really make too much noise. As for the heat reflecting from bodies, yes it's still warm, but not as bad as plain vinyl ones.  I'm pleased with the product and while I prefer no vinyl, if I have to have it, this mattress protector is a good choice.  It's always a crap shoot to purchase online without looking and feeling. But with the great return policy and prices, (did I mention what a great savings shopping at Wayfair is?)
You just can't beat it!  I would recommend this product as well as shopping Wayfair!
