Hi Nannie66,
You can see some of my thoughts about the Pranasleep mattresses in post #3 here and in this thread and a forum search on pranasleep (you can just click this) will bring up more information and feedback about them as well.
The latex they use comes from Latex International and is poured and manufactured in the US. They are one of only two sources of Talalay latex in the western world (the other is Radium in Holland).
