Hi DAK,
I’m familiar with http://www.satarahome.com/ and they sell Savvy Rest and Sueno/Suerte latex mattresses (made by Sleeptek)…
Both of these use high quality materials (natural Dunlop or 100% natural Talalay latex in the case of Savvy Rest and natural Dunlop in the case of the Sueno/Suerte) but they are both more costly than other similar mattresses that use the same materials and design.
They are certainly a good option for testing latex mattresses and are good quality but they are not in the best “value range” compared to other options you have in the area (see post #5 here) … although of course each person may have their own personal value equation which is different from the majority of other people.
Forum searches on Sleeptek and on Savvy Rest (you can just click these) will bring up more information about both of them.
