Hi miso,
Welcome to the Mattress Forum! :).
I am sorry about Purple, and the sleepless nights, I can hear it in your voice. And yes it is crazy sometimes how complicated it can get.
Let me try to help, but I am not going to give you some straight reccomendation, it’s is still going to be up to you to do the work…it is worth it!
Also a quick note on latex…please uderstand that dunlop / talalay (process) and man made blend / natural (formula)…all of these options are very high quality materials, it is like comparing BMW/Mercedes, neither of those cars a “bad” they are all very good. I really reccomend you pay close attnetion to our memebers that have years of latex experience. You can see them listed here.
Also if you want read more on natural (NR) and synthetic (SBR) latex, and info on Dunlop/Talalay you can read Phoenix’s post here.
The companies you listed are good companies, Nest is one of our members, so we are very confident in transparancy and qulaity with all of our members. I am confident you can find a much better latex mattress focusing on a few of our members.
Thanks, it will be worth it soon!
