Hi Jgo,
I don’t have a record or keep track of individual mattresses in any area of the country based on their design or specific materials (which would be more than anyone could keep up with in a constantly changing market) but some of the better options and possibilities in terms or retailers and manufacturers I’m aware of in the Indianapolis area are listed in post #2 here.
The tutorial post includes the steps I would follow and links to the mattress shopping guidelines here which has the guidelines I would use to help you assess any weak links in a mattress. There is also more information in post #4 here that can help you assess and compare the durability and the useful life of a mattress.
