Hi Adrienne,
There really isn’t much that I can add to my previous comments unless you have any specific questions and to encourage you to keep talking with the online manufacturers or retailers that interest to you.
There are also some comments about all latex mattresses vs a latex/polyfoam hybrid mattress in post #2 here but both of the mattresses you mentioned would be great quality/value choices.
Once you have narrowed down your options to a list of finalists that are all choices between “good and good” and none of them have any lower quality materials or “weak links” in their design relative to your weight range (which they don’t) and if there are no clear winners between them (which is usually a good indication that you have done some good research) then you are in the fortunate position that any of them would likely be a suitable choice and post #2 here can help you make a final choice based on your local testing or mattresses you have slept well on, your more detailed conversations about each of them, your confidence about PPP and the suitability of each one, their prices, your preferences for different types of materials or types and blends of latex, the options you have after a purchase to fine tune the mattress or exchange or return the mattress or individual layers, any additional extras that are part of each purchase, and on “informed best judgement” based on all the other objective, subjective, and intangible parts of your personal value equation that are most important to you.
Thanks for taking the time to share some great feedback about your mattress and some of the “fine tuning” you’ve done
