If you have joint problems (I'm facing a diagnosis of rheumatoid arthritis), what kind of mattress do you have?
I'm 33, relatively fit and healthy yet hobbling round like an old woman. My mattress that I have now was a cheap emergency purchase from tesco after I left my marriage and now I need to get it sorted.
I have a memory foam topper on it but to be honest I think that makes the pain worse, not better.
