Hi OhioJer,
If you list the specifics of any mattress you are considering on the forum (see this article) then I’d certainly be happy to share my thoughts about the materials or help identify any cautions or possible weak links in the mattress (see post #4 here) but keeping up with the specifics of all the mattresses on the showroom floors of all the hundreds of retailers or manufacturers that are listed throughout the forum would be a bigger job than anyone could keep up with in a constantly changing market so for the most part I only know what is listed on their sites (which are often not up to date) or what I’ve mentioned in the descriptions in the list.
