certainly pleased with this mattress protector. I like it a lot better then my last one. While it does a great job of keeping the dust inside it also isn’t loud! Meaning you can hear someone roll over down the hallway! My husband moved all night it seems and I’m constantly being woke up. This cover isn’t as nosey as they typically are. The top has a softer material then the rest of the protector. Anyway I’m not sneezing as much now. My allergy’s have improved and I can get a full night sleep! My mattress is 11 inch thick and it took some help getting it on. I don’t think it would be ideal for a 14inch. It’s a top quality product. I washed it and didn’t loose it’s shape or size. All around great product.
