Hi DanInNj,
Savvy Rest does use 100% NR Talalay from Radium, but they are not “specific” about the ILDs they use, just ranges – soft around 15-20 ILD, medium around 30-37 ILD and firm around 37-44 ILD. I’m not sure if any of the component suppliers would know if they have the “exact” same foam that Savvy Rest uses, but they probably have ILDs that are very similar.
As a reference, Talalay in the western world will be sourced from either Radium or Talalay Global (TG). Both companies supply different formulations, some which can be proprietary for larger clients. As an example, Radium has their Embrace, Intuition, Natural Superior and FRX lines, while Talalay Global had additives like phase change materials, graphite and copper they will put in some specialty products.
They are both available in either 100% natural or in a 30/70 blend (NR/SBR) and in practical terms I would treat them as being comparable in terms of durability.
TG blended Talalay comes in target ILD’s of 14, 19, 24, 28, 32, 36, 40, & 44. You can see the approximate density of each of these in post #2 here.
Radium blended Talalay comes in target ILD’s (rounded to the closest whole number) of 11, 15, 19, 22, 25, 29, 34, & 40
Talalay Global uses a filler in their latex formula while Radium doesn’t
Talalay Global 100% natural Talalay comes in N1 (14 - 19), N2 (20 - 24), N3 (25 - 29), N4 (30 - 34), & N5 (35 - 42) with nominal midpoints of about 17, 22, 27, 32, 38.
Radium 100% natural has ILD targets (rounded to the closest whole number) of 9, 13, 18, 23, 28, 33, 39, and 44
You can see a chart for Radium’sILDrangehere.
Most of the manufacturers that I’ve talked that work extensively with both say that they have a comparable “feel” although of course this is subjective, and they all tend to agree that both brands are superior foams. The difference between them would be relatively small and would probably reflect the different ILD’s, amount of filler, and any other differences in compounding formulas and pincore patterns they have.
In practical terms … while there are slight differences between them … I would treat them as equals and the fact that both are Talalay (either blended or natural) would outweigh for me the source of the latex. Radium tends to dominate the Talalay latex market in Europe and Talalay Global tends to dominate the North American market and both of them also do business in each other’s primary markets. They are both well respected and quality products and I would focus more on issues such as which type of Talalay I wanted, the ILD’s of the layers I wanted, and the overall value of the mattress rather than on one brand over another.
