Mattress Forum

I have lower back pain, while my husband has mid to upper back pain. (From bottom to top) F/M/S was recommended for me, while XF/F/M was recommended for my husband. We are back/side sleepers. I am 5'4" 137lbs, Husband is 5'8" 170 lbs.

I have several questions before making our purchase:

 1. Will F/M/S be too soft for me? Shawn said that since I'm lighter, the F/M/S should provide enough support for me
 2. My husband sleeps on his side half the time; will the XF/F/M be too firm for him? 
 3. We may go with the Blended Talalay (instead of the Natural) because it's more within our price range. Any thoughts about this or issues/concerns we should be aware of?
 4. If we get custom layers for my husband and I, if we lay in the middle of the bed, is the split noticeable?

Thanks in advance for your help/assistance!
