Hi KJ,
The closest factory directs to you going north or east are in Post #2 here. There are some good choices in reasonable driving distance. I would call the ones that are closest to you first and talk to them about your preferences of materials and mattresses you have liked and ask what they make that may be suitable. If the call sounds promising, I would take the drive. There is no doubt the quality and value would be much better with any of the manufacturers on the list and they would likely save you a lot of time and frustration as well trying to sort through all the marketing information in the mainstream brands and stores and the frustration that goes with not being able to find any meaningful information that relates to the real quality/durability of these mattresses. Post #2 here has some links with feedback about many of the manufacturers listed.
Going west into Connecticut you also have some good choices but they are a little further away. They are listed in post #2 here. A forum search on “Connecticut” (clickable) will also bring up some posts with feedback about these as well.
Overall … I would tend to north/east.
