Hi Mige G,
You can read more about the factors that can affect and help you assess the temperature regulation of a mattress in post #2 here. While the Chilibed is certainly an option and provides a wide range of temperature options (and I would consider it to be “safe”) … I’m not so certain that the extra cost would be justified in most cases or for most people who may be fine without it on other types of mattress. The Chilibed is also one mattress and may not be the most suitable choice for a specific person in terms of PPP and you may be trading temperature regulation for pressure relief or alignment or other preferences you may have that may be just as important (which of course can only be confirmed by your own sleeping experience). I would be hesitant to choose a mattress based on a single criteria to the exclusion of the rest that may also be important unless you have tested the mattress in person or it has a good return policy.
Oeko-Tex Standard 100 is a safety rating not a “green” rating (they are very different). I don’t think there are any reliable “green” ratings that I’m aware of that are in widespread use so this would really be a matter of assessing the individual materials in a mattress and how it was constructed based on a “definition” of green that met your criteria. There is also more about organic certifications in post #2 here and the posts it links to and as you can see your choice would also depend on the level or “organicy” you consider to be acceptable.
The choice between Talalay and Dunlop would be a matter of preference and not a better/worse choice in terms of quality and I don’t consider one production method to be “better” or produce a higher quality latex than the other. They are just different and both produce a very high quality and durable type of latex that has different properties (see post #7 here). Both have a long history of being very durable. The only latex that has an organic certification is Dunlop. There is more about the different types and blends of latex in post #6 here but all the latex you are likely to encounter (natural, synthetic, blended, or organic in either Talalay or Dunlop) has passed either Oeko-Tex standard 100 or Eco-Institute testing so I would consider all of them to be “safe”. Talalay does allow more airflow than Dunlop so it may be cooler in some applications (depending on the other variables that can affect sleeping temperature).
Yes … bamboo tends to wick moisture more effectively than cotton although it may not be as durable and it’s also “semi synthetic” while cotton can be a natural or organic fabric. There is more information about how they compare in post #7 here and in post #11 here.
I’m not so sure I would agree with your assumptions here. You can read more about individually wrapped latex in post #2 here.
While you are certainly looking at some high quality options, they are not the only ones available to you. Post #21 here includes a list of the members here that sell mattresses online and there are several others that seem to meet one or more (or all) of the criteria you listed that may also be worth considering. I’m mentioning “one or more” because not all of the choices you mentioned meet all of the criteria you outlined and not all of your criteria are based on what I would consider to be accurate information.
There may also be local options available to you that meet your criteria and if you let me know your city or zip code I’d be happy to let you know of any that I’m aware of in your area.
