Hi boltnut,
A list of the better options that I’m aware of in the Tampa area are in post #143 here.
It also includes three of the better outlets that are listed in the Orlando list which is in post #2 here.
Unfortunately I don’t know the foam suppliers of any of these manufacturers or outlets but for those who are OK with telling you (this is not always information they are willing to provide for “competitive” reasons) … a few phone calls would let you know if their memory foam mattresses use Sensus or Aerus.
