"The 6" firm latex core cut in half is the 3" medium toppers. When you make them thinner they loose the firmness

 

According to PFA the statement appears true for PU foam

4.3 IFD varies significantly with foam thickness. On the exact same foam, the IFD increases as the thickness increases, as the following chart illustrates:

All samples are 20" x 20" x stated thickness.
Sample Thickness (inches)    IFD at 25% deflection (lbs/50 in squared)


4---------------------------28.0

5---------------------------31.0

6---------------------------34.5

7---------------------------38.5

8---------------------------43.0

 

Is this statement applicible to Latex ?

PU foam has High resiliance, latex has no resiliance.  Looking more for the facts than opinions.

Anyone ?
