Hi tush915,
The Chicago list is in post #2 and #4 here and includes one of the members of the site. A forum search on “mygreenmattress” or on “qualitysleep” (you can just click these) will bring up more information and feedback about them.
I’m not sure what updates you mean but they are included in the online memory foam list here as a possible good quality/value source although in the case of people in Chicago and what is available there I probably wouldn’t be looking online unless there was a particularly compelling reason to do so.
