Dude this is not a computer or electronics gear. There’s no “upgrade to” - the best thing to do is go to stores and try stuff to see what works for you. Because someone’s “upgrade” might be totally wrong for you. As an example, the memory foam pillows that everybody recommends don’t work for me, I had to test until I found one that worked and is harder/firmer than the usual recommendations.
