Why don't we hear about waterbeds anymore

This is my first time posting.  Before now I was a blogging virgin but no more...  As the last waterbed salesman I ask the question I already know the answer to but most folks don't.  The question is,"why don't we hear about waterbeds anymore?"
     The answer is more than one reason but one of the primary reasons is that other mattress companies don't want to offer them for sale because it costs them more money to deliver. More in both time allotted to each delivery as well as training of delivery person.  If you are reading this blog you probably would qualify as a regular mattress delivery person but precious few would be trusted to deliver a waterbed into a customers home without training and trustworthiness.  The fact that the potential benefits of water exceed any other product on their showroom floor when used properly only makes the decision to downplay flotation even greater.
     I believe the public is being duped by the marketeers and the profiteers.  Well, this is the American way of today and whacha think about that ??
