Hello Langanke, I’m happy to provide any insight I can, although hopefully you’ll get a few responses just so you can make the most informed decision.
**I’m so sorry but I misread your message and thought your weight was 185 pounds, so if you saw my previous response, please disregard it.
We don’t normally recommend our latex and coil Hybrids for folks over 230 pounds because it’s liable to lead to back pain from a lack of support, and this is generally the case with Leggett & Platt’s coils AND Brooklyn Bedding’s Ascension coils.
Based on the information you’ve provided, I would recommend a 10" latex mattress with soft Talalay over medium Dunlop over firm Dunlop for her side, and medium Talalay over firm Dunlop over extra firm Dunlop for your side. The top Talalay layer should provide all the contour and pressure relief needed to avoid any pressure point issues and will add secondary support to the mattress. Secondary support is needed to fill in the gaps between your body and the mattress – back sleepers normally need secondary support to fill in the gaps between the small of their back and the mattress; side sleepers normally need secondary support to fill in the gaps between their mid-section and the mattress. If these parts of a person’s body aren’t supported by the mattress, their muscles will work throughout the night to hold these parts of the body up, and by the time they wake up they’ve got back pain. So the top 3" of Talalay latex will provide contour, pressure relief, and secondary support. The remaining Dunlop layers should provide all the support needed to maintain proper spinal alignment and avoid back pain. Please keep in mind that our initial recommendations have a 90% success rate (we only have a 10% layer exchange rate and a 3%-4% return rate) so there’s a 90% chance that the above recommendation works perfectly for you.
