Hi rierevin,
Just in case you haven’t read it yet … the first place to start is post #1 here which has all the basic information, steps, and guidelines you will need to make the best possible choices.
Once you are ready to start testing mattresses then some of the better options and possibilities I’m aware of in the area are listed in post #2 here and there is also a more categorized list with more detailed descriptions of many of them in post #7 here.
Of course if you have questions along the way feel free to post them here.
