Hi atticia67,
I personally wouldn’t mess with success and I would listen to your body vs your mind. Your mind can’t feel a mattress when you are sleeping but a mattress that is suitable for your body can have a significant effect on your ability to rest and recover over the course of the night and how your body and your mind feels when you are awake. I would always prioritize what you need vs what you prefer if there is a conflict between the two.
If you are sleeping well on your mattress I would also give things a few months so that you can get used to a sleeping system that is different from what you are used to before making any changes.
Adding something softer to your mattress will also involve some level of risk in terms your alignment.
Like any subjective feeling “sleeping on a cloud” also means different things to different people so it’s not really possible to provide specific advice but if you do decide to add a mattress pad or a topper to your mattress to create a different “surface feel” then something that is somewhat fluffy may produce the feeling you are looking for. Perhaps a featherbed (which tends to be costly) or a lower cost fiberbed (made from “down alternative” polyester fibers) would be what you are looking for. There is more information about featherbeds and fiberbeds in post #6 here and the posts it links to.
While some people may describe sleeping on a wool topper as being like “sleeping on a cloud” … wool may have a firmer “feel” than you are looking for, especially as it packs down a little over time. There is more information about wool toppers in post #8 here and the posts it links to as well.
Since you won’t know for sure whether any mattress pad or topper will “feel” the way you want it to feel until you try it on your mattress … I would make sure that you are comfortable with the options you have to return or exchange a product before making a purchase just in case it doesn’t work out as well as you hoped it would…
