It's a nice mattress. It's recommended to get the mattress protector because of the warranty, but I hate it. Mattress protector takes away from the cooling. Yes when you first lay on it, it's cool, but after a few seconds it goes away. I'm a hot sleeper that's why we got the cool mattress, but having the mattress makes me sweat as if was a regular mattress. Also if it's warm in the house the mattress isn't as cool to the touch.
