Hi Restless_inNJ,
I think that the absolute best way to become “unconfused” would be to talk with them so they can tell you about the differences between the options they offer. They will give you accurate information that will help you know what is in your own best interests.
You can read more about the differences between different types of latex in this article as well as post #6 here.
In most cases … “organic” latex would be of interest for people who put more value in the certification itself than they do in the quality or performance of the material and are willing to pay a higher cost for it because 100% natural Dunlop latex and organic dunlop latex are functionally the same except for the certification itself.
In the same way … 100% natural Talalay (there is no organic Talalay) would probably be of more interest for those who are willing to pay a higher cost for a slightly less durable material (in the lower ILD’s anyway) with a very similar feel and properties just because it’s natural.
In most cases … 8" - 9" of latex is perfectly fine (and what Shawn at SleepEz normally recommends) unless other factors such as much higher weights or in some cases personal preferences indicate that more latex is a better choice. Post #14 here has more information about the potential benefits of a thicker latex mattress.
Again … there is no “organic” Talalay latex … only Dunlop. The choice between different types of latex though would strictly be a matter of personal preference based on what is most important to each particular person rather than a “better worse” choice.
When you are dealing with high quality, knowledgeable, experienced, and ethical manufacturers that will give you accurate information rather than “marketing” information … especially if they use all the different types of latex so they are more “neutral” and balanced in their outlook and the information they will provide you … the most important part of any purchase decision will be your more detailed conversations with them.
Hope this helps
