Hi Wave1911,
I would completely “reset” how you are looking for a mattress and the first place I would start your research is the mattress shopping tutorial here which has all the basic information, steps, and guidelines that can help you make the best possible choice … and more importantly know how and why to avoid the worst ones.
Post #3 here and the posts it links to also have more information that will be helpful for those that are in higher weights including some suggestions for couples that have a large weight differential.
The better options and possibilities I’m aware of in and around the Long Island area (subject to the guidelines here) are listed in post #4 here.
