I love this bed. It did take more than 72 hours for it to "even out" after being unrolled, which had me a little concerned, but this is week 2 of using the mattress with chronic back pain, knee issues and hip pain and I don't toss and turn nearly as much. I also went from  a max of 4 hours of continuous sleep to 6, and am hopeful with other life style changes I might actually sleep through the night soon. I haven't slept this well since my daughter was born almost 5 years ago!
