Hi chrstnamarie,
It uses a single 6" core of blended Talalay latex and has a bamboo viscose cover quilted with wool on both sides (as you mentioned). You would need to check with Arizona Premium to find out the firmness levels they have available.
The SleepEZ uses two 3" layers of 100% natural Dunlop where you can choose the firmness of each layer and has a stretch knit cotton cover that has no quilting. It’s a one sided construction where you can choose progressively firmer layers from bottom to top instead of choosing the firmness of a single layer.
There is more about the different types and blends of latex in post #6 here and there is more about the differences in “feel” between Dunlop and Talalay in post #7 here.
Both of them are members of this site, would make very good quality/value choices, and would be well worth talking to.
