Hi Desireenicole311,
As you mentioned Troy, MT is somewhat of a desert in terms of mattresses :unsure:
If I was in Troy, MT I would probably head in the other direction to Coeur d’Alene which is only a little further away than Kalispell. You can see some of the better options and possibilities there that I’m aware of (updated today) listed in post #4 here.
http://www.managhansfurniture.com/ Is in Libby, MT but when I talked with them they only carry Serta (which I would avoid) and some of the lower end promotional mattresses made by Northwest Bedding in Spokane. He was knowledgeable about mattresses and the industry and he is about to start carrying some of the higher quality mattresses made by Northwest Bedding in the next few weeks so this may be a reasonable option to include in your research when that happens.
Hope this helps a bit.
