Hi sajurcaju,
I’m sorry you’re having difficulty getting replies to your questions. Phone calls are always the best way to get the fastest response, but I see you’re having some difficulty getting responses form a few of those. All I can think of is that some of these companies may be on extended leave or short-staffed still for the holiday period. I’ll see if I can find out anything for you and will post back if I do find something out for you.
Because of the difficulty in standardizing testing for memory foam, not every vendor may have ILDs for their memory foam or have them provided to them. The density would of course be more relevant. And most important would be what we discussed previously, finding a more “traditional” version in the density matching yours without the faster recovery and gel/phase change additives.
Yes, I think you’re referring to post #5 here.
Here are a few others I found who sell memory foam in pieces after a brief search if you’d want to contact them and see if they have anything that might work for you.
