I was very skeptical purchasing a bed that I haven't touched or laid on. I took a gamble, but it was well worth it. The delivery time was 15 days and the packaging looked that of a Pillsbury dough boy can. There was a smell, but it was very faint. The bed expanded rapidly and took little time to reach full size. I purchased a medium, I wish I would have bought the soft one instead but I still love the bed. My medium is pretty firm, but very supportive. When I lay down most of body I can feel sink into the bed while my feet and head are slightly higher. I would recommend this bed to ANYONE, especially someone who has back pains. The main reason why I purchased it was due to my wife and I both having severe scoliosis and after three weeks improvements are very noticeable. It isn't going to fix our spines but every night has been a great night of sleep, every day when we wake up and we are fully energized and it stays with me all day long. Well, there isn't much more I can say, it is an excellent buy and I would recommend the soft, if my medium feels to firm there is not telling how hard the firm bed is. I am sure that if you get the soft, you will still get a very supportive and relaxing sleep continuously. Hope you enjoy your bed as much as I do.
