I'm amazed. Its perfect! Not rock hard or plush soft. Super comfortable!Absolutely no movement on one side of the bed when someone is moving around on the other side. I'm absolutely in love with this mattress. I knew that I was going to love it as soon as I laid down on it the first time. It's soft while still being supportive. I love the feeling of sinking into the mattress when I lay down. We've been sleeping on it for a month now and I always feel well rested.
