I am a disappointed with the mattress. First the mattress is way squishier then I thought it would be. (Keep in mind I got the Firm twilight Dawn as well). So when we are sleeping together if we sleep to close then we start sliding into the middle. The other thing I was concerned about was the cooling package I bought on top of the mattress. I still get very hot and all I sleep with is a sheet. It is a nicer mattress then my 10 year old one but disappointing on the price and what I got vs what it claimed it would do.
