Hi WebbyR,
You are certainly welcome to attach a picture to your post or add any other information that may be useful although I’m not sure how helpful it will be in deciding on the types of changes that have the best chance of being successful because there can be so many variables that are part of any sleeping issue … especially when there are health issues involved which can make things much more complex and unpredictable.
The first step is to decide on which parts of the body need to sink in either less or more and whether the changes you are looking for are about primary or secondary support or pressure relief.
There is more about primary and secondary support and their relationship to pressure relief and firmness in post #4 here and in post #2 here that may help you visualize what good support/alignment and pressure relief “looks like”.
