Hi alberta05,
I’m glad you found the post with the information you were looking for. Sometimes there are so many posts in the forum that it can be difficult to find the ones that provide the best answers to your questions (and I’m usually more than happy to point in the right direction by linking posts that are relevant).
In case you are also looking for local mattress options that you can test in person … some of the better choices or possibilities I’m aware of in the Louisville area are in post #3 here.
