Hi bgaviator,
If you let me know your city or zip code I’d be happy to let you know of any of the better options or possibilities in your area and you could check with them to see if any of them have a latex hybrid mattress that may be “somewhat similar” to the Ultimate Dreams Eurotop. I would keep in mind though that there are hundreds of different styles of latex or latex hybrid mattresses (that may have softer or firmer comfort layers for comfort/pressure relief and softer or firmer support cores for support/alignment) just like there are hundreds of different innerspring mattresses that can be very different from each other so testing one may be completely different from testing another with a different design. There may be some local options though that can give you a sense of the “feel” of Talalay latex (which is the type of latex used in the Eurotop). One of the advantages of the Eurotop as well is that if your sleeping experience indicates that the comfort layers are too soft or firm for you that you can exchange them for a different firmness level.
Since you are also in a higher than average weight range it would also be worth reading [url= https://forum.mattressunderground.com/t/best-mattress-for-the-plus-size-people]post #3 here[/url] and the posts it links to about higher weights. It may also be worth considering one of the mattresses from Dreamfoam’s sister company Brooklyn Bedding which use a higher density base foam and/or thicker layers of latex that may be a better choice to accommodate your higher weight (see post #2 here and post #2 here).
You can read some of my thoughts about airbeds in this article. I would also keep in mind that the only thing you can adjust with an airbed is the air bladder support layers … not the comfort layers … and that softer settings may be risky for good alignment because they can sag in the middle of the mattress where you may need better support.
When you can’t test a mattress in person then your best source of guidance will be a more detailed conversation with a manufacturer or retailer (in this case Dreamfoam). They will know more about their mattresses and which of the options they have available would be the best match for different body types and sleeping styles and would have your best chance of success than anyone else (see mattress firmness/comfort levels in post #2 here). I would keep in mind that a mattress that is “perfect” for one person or couple may be completely unsuitable for another.
