In response to the third item I agree to a point, but I think that there is also a case to be made for personal preference/requirement. If you are a lighter person and prefer to sleep on a firm bed I don't see a problem with that. Additionally different people have different requirements and this may or may not relate to their height & weight. I bring this up because I am a slim athletic person and I sleep on a firm natural latex mattress that I bought from here http:thenaturalsleepstore.com about 3 years ago.
