Hi zexpress,
Just to update this topic and discussion … I had the chance to talk with Lori at 4sleep both yesterday and today. She was certainly knowledgeable, open, and transparent about themselves and their new mattress and I enjoyed our conversation. Their mattress uses good quality materials and outside of those that are in higher weight ranges (more than the low 200’s or so) there are no obvious weak links in their mattress so based on our conversation I’ve also added them to the list of “simplified choice” mattresses in post #3 here where you can see some of my comments about our conversation and their background as well.
