The Ramada in Durango CO has them, but that probably isn't much help. So put Google to work, and try some combinations like "Connecticut Hotel Tempurpedic" (or Massa... whatever).
There seems to be one in Stonington CT.
Though questionable how much you will find out. When we stayed at the Durango hotel especially to try the beds, they had some super hard hotel version that was like just about the worst non-,memory foam hotel bed I have ever slept on. It seemed to me anyone who could sleep on those beds could sleep on ANYTHING and had no need of a $2k trick bed. Obviously TP makes some beds that we might have been happier with, but a sample group of 1 does not often produce useful results.
