Hi incognito,
The electropedic family of websites (including latexpedic) are all a horrible design and difficult to navigate!
You can read a little more about the Electropedic’s Organic Comfort mattresses in post #2 here. They use high quality materials and there are no lower quality materials or weak links in their design.
The first mattress you linked uses Talalay latex which isn’t organic (there is no organic Talalay latex) but the second mattress uses organic Dunlop latex.
There is more about the different types and blends of latex in post #7 here.
