Hi Dangeresque55,
Yes … the Dunlop that SleepEZ uses is 100% natural molded Dunlop. All three of these versions of latex (and all the different types and blends of latex) come in a wide range of firmness levels so any one of them may be firmer than any one of the others depending on the firmness of the specific layers you are comparing. The softest versions of continuous pour Dunlop though would be softer than the softest versions of molded Dunlop that you are likely to encounter and would be similar to the softest versions of Talalay. There is a little more about how Dunlop (of both types) and Talalay compare in post #7 here but the best way to know which one you tend to prefer would be based on your own personal experience.
I don’t know the specific layering and materials in the Therapedic Natural Splendor or the Therapedic Blue Heaven so I can’t make any meaningful comments about either of them but if you can provide the specs of both of them and list them on the forum I’d be happy to make some comments about either or both of them. I can make some comments about the other three however.
Both of the SleepEZ mattresses and the Spindle Abscond have a similar 3 x 3" layer design with a wool quilted cover so in this way they are similar. The SleepEZ natural provides the choice between blended Talalay and 100% natural Dunlop and the SleepEZ organic provides the choice between 100% natural Talalay or 100% natural Dunlop and has an organic cover but there would be little reason to choose the Organic version with Dunlop layers since the Dunlop is the same in both lines. There is more about the different types and blends of latex in post #6 here. All of these mattresses use high quality and very durable materials and there are no weak links in any of them.
All three of them provide the option to choose the firmness of the layers before a purchase and have the option to either rearrange the layers or exchange them and both of them have a return policy but the exchange and return policies are different and there are different costs involved.
Any one of these three would make a great choice and when you are down to finalists that are between “good and good” and if there are no clear winners between them then making a final choice (see post #2 here) about which one would be “best for you” would be a matter of “best judgement” based on your more detailed conversations with each of them and on all the objective, subjective, and intangible criteria that are most important to you or in some cases it may even be a matter of which way you find yourself leaning.
