Hi Hammer,
I’m glad you had a chance to try out a few different latex products. It’s always best to do your own personal testing, as you found it it’s more accurate than being able to touch foam samples (although those can be quite useful as well).
Both the Nature and Nutrition are all Talalay mattresses. The Nature uses a 6" core of 36 ILD, with 2" of 28 ILD and 2" of 21 ILD above that. The Nutrition uses the same 6" 36 ILD core, with 2" of 19 ILD above that and 3" of 28 ILD Talalay on top of that. The upper layer in each mattress uses the paraffin wax ActiveFusion phase change material. The cover is a 98% polyester, 2% elastin mix, and under the cover there is a FR layer that fits like a mattress pad over the latex layers to meet flammability requirements.
If you’re looking to approximate those comforts, there are some online options with component style systems where they can approximate quite closely the mattresses you tested locally, often at a more competitive price. Many of the members listed in post #21 here are very experienced and knowledgeable and specialize in providing the type of help and guidance on the phone that can help you make good comparisons to the Pure Talalay Bliss line, with a wide range of latex options. I believe that all of them compete well with the best in the industry in terms of their quality, value, service, and transparency. While it’s not possible for me to maintain a listing of all of the latex options available nationally, those site members would be a good place to start your research. You can also do a simple search for Talalay latex mattresses for more options.
If you have more specific questions, please let me know, but hopefully that helps get you started with your comparisons.
