Ponderings: Bed Firmness

I don't have any letters to write for today, so instead I'm just going to ponder. A while back, I checked out some mattresses with my lovely significant other. After all, when we decide to get married, it's important to get a bed we both can be comfortable in. Curious how different our tastes are, we went to the SleepNumber store and got our "sleep numbers." Hers was higher than mine. I wonder if that's normal. Then I remembered how she commented how she liked my firm structure and I said I preferred her being soft. I wonder if the degree of softness in a bed is related to the firmness of the body someone likes. Of course, asking different people about their physical preferences and beds is improper so I have not been able to do more than ponder. To be honest, I think it was more of a coincidence, but it would be interesting if these two things were related. Tell me if you found this to be the case as well.
