Hi Realigned,
While I certainly recommend the members here as a group … I don’t make specific recommendations for either materials, mattresses, or manufacturers. I would start with a phone call to the manufacturers on the list that are members here to talk about your situation and criteria (step 3 in the tutorial) and then decide which ones to visit based on your conversations. I also wouldn’t “assume” that you need a zoned latex mattress (see post #7 here) and I would do some careful testing and let your body tell you whether any specific mattress (zoned or unzoned) is a good “match” for you in terms of PPP.
All the members of this site are knowledgeable and experienced and I believe they all compete well with the best in the industry in terms or their quality, value, service, and transparency and would be well worth including in your research.
