Hi Hypnotiq,
There is more about “matching” one mattress to another one in post #9 here and the posts it links to. I don’t know of any other “all latex” blended Talalay latex mattresses that use the same layering and design but there would likely be other Talalay latex mattresses that use different designs that would also be an equally good (or perhaps even better) match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) even though they didn’t have exactly the same “feel” or design. Post #32 here also has some online sources for the Pure Latex Bliss mattresses that you call and talk to that you can use for value comparisons (PLB has MAP pricing which means that the posted price is controlled but if you talk with them you may find that the actual selling price is lower).
The tutorial post also includes a link to some of the members here that sell latex mattresses online (in the optional online step) that include a wide range of features, designs, types of latex, and budget ranges.
