So my spouse (5’2", 130, back sleeper sometimes side) has told me she has back pain from not proper alignment. We have a good bed frame, and her side is 9 inches of DunlopFirm. But now she’s on the floor sleeping better on three inch futon. So maybe she needs something firmer? If I switch out the bottom 6 inches of latex for the caliber edge coils, and then 3 inches Dunlop on top, would that be firmer than her current set up?
Thanks
