Hi Phil P,
Thank you for your kind words.
Here is a coir bed rug. It’s made of coconut fiber and held together with a natural latex adhesive. It is firm and allows for air circulation beneath a mattress placed upon a firm, flat surface.
If you do that, you may wish to forgo the coir bed rug.
These bowed slats can perform as a bit of an active sleep surface and accept some of the load placed upon the mattress, and some of these slat systems are tension adjustable and they can change the feel of the mattress in certain areas, and their impact will be more noticeable when used in concert with thinner mattresses (see post #2 here). If the bow is substantial, adding the flat decking material may end up causing noise.
These are all questions that I can’t answer for you, as they’re all part of your own personal value equation. While price is certainly important of course, the “value” of a mattress purchase is what is most important and price is just one of many factors that can affect the “value” of a mattress purchase. There isn’t a “formula” that can be used to assess or “calculate” the value of a mattress because there are so many different variables and criteria involved that can affect the price of a mattress that can each be more or less important to some people and not to others who may have completely different criteria or definitions of “value”. The value of a mattress purchase is also relative to how a mattress compares to the other finalists you are considering or to other mattresses that are available to you in your area (or online if you are also considering online options). There are many reasons that a mattress that may be “good value” for one person or in one area of the country may not be good value for someone else that has very different needs and preferences or that lives in a different area.
With that being said, every change in layering will impact comfort. Going from 2" to 3" is a 50% increase in comfort material. You’ll tend to notice more of a difference between Dunlop and Talalay latex versus the difference between blended and natural. Aside from that, it really would come down to your own personal testing of a product. The Dreamfoam Ultimate Dreams you mentioned uses a blended Talalay. Based upon the firmness data on the Eco Terra site and their import records, I think they are using Dunlop (you’d want to call and confirm). The Arizona Mattress offers both Dunlop and Talalay. The My Green Mattress uses Dunlop latex.
I would make a list of the pros and cons of each product and then compare two at a time, looking at price, configuration options, ability to customize, totally overall componentry, Dunlop or Talalay, return policies, etc. Only compare two items at a time, and eliminate the “loser” from contention. You’ll eventually come up with your “winner”.
