Hey stmslpr,
Hey thanks for the detail in your post. Berkely Ergo products, very well known and high-quality products.
This is interesting but not that surprising (Berk firm talalay core ild?). Phoenix has a post about it - differences latex core vs innerspring post#2 that discusses some of the technical differences.
This is interesting as I think I know this Belgian foam, with the fast response, did you feel the foam itself or see it? It’s light blue or it was light blue. It is very nice “memory foam” and really makes the answer to this question more difficult. And really it’s more of a “you” question, as everyone could have a different preference.
Your descriptions are very robust, for the 8" Talalay mattress, which is high quality, but different…and not everyone. The zoning is cool looking, but as a core, one cant feel the different zones. Did you have an additional 2" Talalay topper on top of the Amsterdam?
It sounds like your getting close, and the coil move worked so far. Let us know any other questions I am sure I missed something.
Thanks,
Sensei
