Have you, or can you categorize the manufacturers on your membership according to the materials they offer? I’m primarily interested in talalay latex mattresses.
thwimsatt - I’m not aware of a fully categorized index but was able to locate the following post which includes a list of forum members selling latex mattresses, and it includes some detail about the type of latex products that each offers. Hopefully it will meet your needs: https://forum.mattressunderground.com/t/latex-mattress
Hi thwimsatt,
Welcome to the Mattress Forum! 
Funny you should ask. I’m currently creating a sortable database for the site business members. But until that is done, business members carrying some form of latex are listed in a reply I offered just a week ago here.
And you can also look through the online sources link for members in the post Sweet Dreams supplied. (Thanks Sweet Dreams!)
Of course, all of our business site members are listed here.
