Hi Brick,
D85, D95 etc is the density expressed in kilograms per square meter (kg/m3) which is the most common Dunlop specification.
Post #4 here can give you some idea about how this may translate into ILD but this would not be exact because of all the reasons I mentioned in the link I posted previously.
Arpico is a Sri Lankan Dunlop manufacturer which makes good quality latex.
Typically yes (assuming we are talking about D85) … but of course this is impossible to know for certain for any specific person without them lying on the mattress and the D85 itself would itself not be a specific ILD. It would also have a firm side and a softer side (Dunlop latex settles in manufacturing and is firmer on the bottom of a core) which can make a slight difference.
A D95 would be very firm for most people and would typically need a thicker comfort layer than a D85 would to get to the same level of comfort and pressure relief but again body type and weight distribution and sensitivity to pressure would still be a variable (not just weight) and each person can be very different even if their body weight is the same.
Being allowed an exchange would certainly take some of the “worry” out of the picture.
