Just a stargazer

I have less than five months to buy a new bed. Of course, this should be plenty of time, except I am like Goldilocks and I want a mattress that is “just right.” I am like the Princess and the Pea, waking up black and blue whenever there is so much as a marble under the mattress. I’ve looked into some different options (and I found out my sleep number) but every time I think I’ve made up my mind, I come across conflicting information. Am I doomed to wake up in pain every morning no matter what I sleep on? No matter what the cost? I’m looking for a panacea, and I wish I could find one in my bed.
