I purchased this mattess to replace a 20 year old set which I had complemented with a foam topper for the past 5 years. The topper had convinced me that foam was the way to go. BUT, this mattress was the confirming factor. I fall into such a deep sleep that I cannot recall when I drift off and before I know it I have slept 6 hours. It's been a long time since I can claim such restful nights and I have sleeping on it a week now.
