After 10 days of use I am amazed at how much better we are sleeping now. We were sold after the 2nd night for sure. It just allows for a deeper and uninterrupted nights sleep. I have my side set in Auto mode and her side is set in Automatic mode. We can hardly tell if the other is moving around at night- which use to be an issue with our old mattress. Delivery was a breeze and they set it up fast.
