Hi timinswfl,
Yes … you are right on both counts. The real problem with mattresses like these where you don’t know the details of what is inside them is that no matter how it feels in the showroom you have no way of knowing how it may feel in a year or two down the road. Without the ability to identify any potential weak links in the mattress (usually too much lower density/quality polyfoam or other materials in the comfort layers) … you could end up with a very expensive mattress (more costly than many other mattresses that use the same materials) that softens and breaks down too quickly without any recourse (warranties only cover impressions and factory defects … not the loss of comfort or support that goes with foam softening).
Of course I also wouldn’t purchase a mattress that wasn’t suitable in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) no matter what the quality of the materials were. Something that you don’t like or isn’t suitable that uses good quality materials that last for a long time will only maintain the feel and performance that you don’t like for a long time
Unfortunately there are no manufacturers that target the Dr Breus lineup in terms of their design or feel that I’m aware of (although there are many manufacturers that use the same materials in their mattresses in different designs). I don’t think any manufacturer would consider that the Dr Breus line was available widely enough, popular enough, or high enough quality to make it a worthwhile design goal even if the layers were known so any comparisons would need to be based on “feel” alone in side by side testing. While another mattress may feel similar based on subjective comparisons … this also wouldn’t tell you anything about the quality of the materials or how long the similar “feel” will last.
As you can read in post #2 here about “mattress matching” … I would tend to use a common set of criteria as a common standard for all mattresses you test which can help you identify why you like each one rather than trying to match one mattress to another based on subjective perceptions that can vary with both time and circumstances.
I would also suggest that you test for much more than just subjective 'feel" or “comfort” alone and test as carefully, objectively, and specifically as possible for both alignment and pressure relief which are the two most important functions of a mattress that contribute the most to the quality of your sleep over the long term.
