I chose the soft and we are very pleased with everything about the bed. I purchased it for my son, and we all like it. We are even considering a larger one. It does tend to hold in more body heat making it a little warmer than a regular mattress once you lay on it a while, but it does not seem to be really hot feeling like I had expected. Although it is soft, it is firm enough that you don't sink completely down into it yet you don't feel like like you are sleeping on a board either. There was no smell at all to the mattress that we received and it took shape within a hour or two. It is easy to move around and suits our needs very well.
