I think the basic answer is no, high quality latex does not sag after a short period.

Look at the content label on the mattress to see what the components are.

So...the answer is:  it is the wool and cotton compressing.  I guess I need a mattress with a very thin, if any, layer of wool or cotton on top of the latex.  Perhaps some mattress surgery is in order!

Has anyone ever had this issue with a dunlop mattress?  Or a mattress with a primarily dunlop core?  

I think the softening that people talk about is a temporary thing while the latex is warmer.  Not a permant indentation.  I am still skeptical that latex international latex has developed an indentation over a short period of time.  Most likely it is the wool/cottom layers getting compressed.
 

I agree a properly cured zoned latex core should not sag.  I do believe, however, that a 100% talalay core could have that deeper sensation that may be misread as a sag type of problem.  If you have wool compressing it may well simply be an unrelated visual cue unrelated to the sensation of depth.

Others will answer as well, but no. It doesn't soften and mold to your body the way memory foam does. It's springier. It's soft when you lay on it but bounces right back when you don't.  It does not retain heat as much as memory foam, but for some (myself included) it does still retain quite a bit of heat and causes sweating. Your results may vary of course.

If you get a chance, ask to see a sample of the latex core of a mattress, or find a photo of one online.  You will see that their are row upon row of symetricly placed holes across the surface.  These holes which will be anywhere from a 1/8" to 5/16" in diamiter go all the way through the core.  The holes help determine the firmness of the latex core and they allow the core to draw heat away from the body on top of the core.  And they do a pretty good job.  If you go back thirty years, the most common and often heard complaint about latex mattresses was they cot so very, very hot!  In the latex mattress industry today we don't realy hear that complaint very much.

Hope this helps,

It felt as though the latex itself would soften after I had laid in one spot sleeping for several hours, it felt as though my hip joint had melted down into it.  But I agree, it is difficult to ascertain due to the wool/cotton already being compressed in just that area, and with those layers being so thick in the first place -- the depression was already rather pronounced.  They hauled it out of here this morning, so no more of that.

I have placed an order for the Sam's Club American Sleep Organic Mattress.  They say it is in stock, but they give no indication whatsoever of when it might be delivered.  So the journey continues!  

Which Sam's Club mattress did you order?  Link please.

At least you can return to Sam's Club if it doesn't work out.  Is it the Latex Green one or the Latex International one you ordered?

My toppers from Latex Green and Latex International and Dunlopiillo (now gone) have not sagged, or indented any.

I don't know if there is a legal way to build any finished mattress that will not sag one bit.  you would almost just have to buy several different layers of latex yourself and get a simple cotton mattress cover for it, this would be the least amount of sag with a latex mattress.  Or in my experience it seems that Tempur Pedic mattresses hardly take a body indentation if any...however they do soften up dramatically with useage and do lose some support.
