Hi LizW,
Welcome ... and I'm glad you found us
You are certainly looking at a great quality/value choice and as you probably know Arizona Premium is a member of this site which means that I think highly of them and that I believe they compete well with
the best in the industry
in terms of their quality, value, service, knowledge, and transparency.
I do plan on giving them a call when they open tomorrow (I am in the Indianapolis area-46140 so we are on EDT), but could explain the properties of the two types of latex?
I understand that the Dunlop contains more latex and is denser/heavier than the Talalay but I am trying to understand how the materials react to pressure. For example, would the airier (word?) Talalay just compress under pressure or displace outward? I am thinking along the lines of a 22-28 ILD, so a medium? This is probably a really stupid question, but on the SNB, the air will displace within the bladder causing some areas to be more firm (shoulders & arms) and others quite less (rear & hips).
The choice between different types and blends of latex is more of a preference and budget choice rather than a "better/worse" choice and any type or blend of latex is a durable material relative to other types of foam materials. There is more about the different types and blends of latex in
post #6 here
and more about how Dunlop compares to Talalay in general in
post #7 here
but the best way to know which type or blend of latex you tend to prefer will be based on your own testing and/or your own personal experience.
When you can't test a mattress in person then the most reliable source of guidance is always a more detailed phone conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart and who can help "talk you through" the specifics of their mattresses and the properties and "feel" of the materials they are using (fast or slow response, resilience, firmness etc) and the options they have available that may be the best "match" for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked or other mattresses you are considering that they are familiar with, and the "averages" of other customers that are similar to you. They will know more about "matching" their specific mattress designs and firmness levels to different body types, sleeping positions, and preferences (or to other mattresses that they are familiar with) than anyone else.
You can see my comments about airbeds in general
this article
. Air (and water) will displace so pressure in one area will affect other areas of the air or water bladder but foam materials will compress under pressure (like a sofa) without affecting the areas outside the area of compression.

If you are also interested in testing some local options then the better options or possibilities I'm aware of in and around the Indianapolis area (subject to making sure that any mattress you are considering meets the the
quality/value guidelines here
) are listed in
