We have slept on our mattress for over a month now. We both fall asleep within 5-10 minutes. This mattress is super comfortable and not as warm as our last Tempur-pedic. My husband is typically hot and I am typically cold. This mattress has just the right temperature for both of us. Advice for a new buyer--have the delivery people help you take a photo of your mattress tag. You will need it for your warranty. I put all the sheets and covers on, and had to take them all off and lift the mattress to get the serial number. Difficult even for two people!
