Hi 1nightstan,
I don’t have any personal experience with any of the products you mentioned but hopefully some of the members here that do will see your post and share their comments and feedback.
If the foundation you are referring to is the Simple Life foundation then an exact term site search on “simple life” (you can just click the link) will bring up more comments and feedback about it and it would certainly make a suitable choice for the BestMattressEver. This topic also has more information about support systems that would be suitable for your mattress as well.
While I can’t make any specific suggestions for anything that you can “feel” because there are too many individual preferences involved and only your own experience can tell you whether any pillow works well for you … there is more information about choosing a pillow in the pillow topic here and the other topics it links to that may be helpful.
There is also more information about sheets and bedding in post #7 here and the other posts and sources of information it links to that should be helpful as well.
