Phoenix,
Homework done. 
Now I have questions.
- Natural Talalay is less durable in softer ILDs in a comfort layer than the blend. At which point there is diminishing durability becomes obvious? 19ILD? 21ILD? And do you work the blend % into this formula? I am asking because we like a bit firmer surface, so I want to see if we should go with a blend or NR (see, I am using abbreviations now
) - Is SBR chemical safe? Any smell? Toxic? What is it made from?
- ILD can be confusing from one web site to another. Some refer to individual layer ILDs, while others indicate the ILD for the “total feel”. Is there a way to compare? For example 6’ Dunlap 26ILD + 2’ Talalay 19ILD = ? “total feel” 28? 32?
- I am surprised you mentioned Habitat uses blend Talalay… their website says “2” layer of softer Talalay Natural Latex"… or they differentiate between Bontanically derived and Natural? How misleading if that’s the case. :unsure:
- Is there an updated list for smaller independent manufacturers of latex mattresses in Miami? Your post #2 here is over 1.5 years old, so I was not sure if you have any updates. After reading my homework I decided to make more effort to try and get my mattress locally.
I really appreciate your dedication to this website. Your attention to my question makes me feel special. I feel I have come a long way from the moment I first came across this site. And while my lower back is still killing me every morning, learning so much is making me more confident that I will make the right choice and enjoy restful sleep for many years to come. :cheer:
