DIY topper, simulating store bought top layers?

[phoenix]

Hi If It Wasnt For the Foam,

I should have been more clear in that I was just curious about making a tufted/quilted top layer and what kind of foam and fiber to put inside. I planned on something like that over another layer of latex, either 1" or 2". The 2" latex I had was missing the nice soft, pillowy top layer.

This would be much more complex and uncertain than I would personally be willing to try and even if you were able to quilt or tuft the materials together (which normally takes specialized machinery) you still wouldn’t have any certainty of success because you don’t know the specifics of the materials that Stearns & Foster is using that you are trying to duplicate (and it would be unlikely that you could find out) so it would be difficult to put everything together and then test it to see how close you came only to find out that it wasn’t what you wanted and then have to undo all your work and change the materials and then quilt or tuft it again to test another version to see if it was close to what you wanted and then keep trying different trial and error combinations until you happened to find a combination that feels the way you want it to feel. If it was me the effort and complexity wouldn’t justify the potential rewards and risk but if you do decide to give it a try then I would be interested in finding out how it turns out for you.

Now I’m a little confused by the blends/varieties of latex as I read about dunlop and talalay, and while reading dunlop is more dense I found one place that has 18 ILD dunlop blended latex:

There is more about the different types and blends of latex in post #6 here and there is also more about the differences between Dunlop latex and Talalay latex in post #7 here but the choice between Dunlop and Talalay is a preference choice and the most reliable way to know which one you would tend to prefer would be based on testing both materials in a range of firmness levels.
