Hi lax2luv,
I think you’re referring to the Dreamfoam Ultimate Dreams latex/pocket coil here which has 2" of Talalay latex and some polyfoam in the comfort layers, but I’m not sure of the specifics of all the layers and components. If you’re considering this item, I would phone Dreamfoam directly and make sure that you find out information listed here so you can compare the quality of the materials and components.
Post #2 here also lists some more of the site members who offer latex and spring mattresses.
