Hi rurede4m,
I would keep in mind that the Ultimate Dreams is among the best quality/value in the industry (which is why they are one of the members here) which means that there are not a lot of manufacturers that will “compete” with them.
Having said that … I do think highly of the materials and design of the Tempflow mattresses and Dr Rick who designed them and you can read more of my thoughts about them in post #9 here.
Overall the Tempflow mattresses use good quality materials and are better than average value (especially compared to mainstream manufacturers) but they also sell through retailers which means that they won’t have the same cost structure as a factory direct manufacturer (they don’t “undercut” their retailers). There is also real value in being able to test a mattress in person for PPP (Pressure relief, Posture and alignment, and Personal preferences) so they have some benefits that aren’t part of an online purchase. In other words … each person’s “personal value equation” (what is more or less important to them) and their risk tolerance ( the options available if the wrong choice is made) may be very different.
