Literally... My wife and myself love this bed. We received it in just about 1 week. Set it up, and we waited 72 hours. So far, we have slept on it for the past 4-5 nights and it has been wonderful. I am 6'2" at 260 LBS. I have had back problems since I was 5. This bed relieves so much lower back pressure, I fall asleep quickly. When I get out of bed and take a 15 minute shower, I go back to wake my wife and my side is already raised back to normal. I am on call 24/7, and so far she has not felt me get out of bed, can't help it if she hears the phone ringing off the hook. We were positive it would not compare to the $4000 name brand beds, but it sure is nice. The expensive firm is not quite as firm as the overstock firm. If you want a little extra give, go for the medium or most likely the soft. I needed good support, so I went for firm.
