I have from top down I am currently using: 1" 19 ILD latex, 1" 5.9lb. memory foam, 1" 24ILD latex, 2" 32 ILD latex, 782 Sealy coil system (fairly firm, I would estimate at least 40 ILD compared to latex). I have a 100% cotton mattress pad over all of that, and a wool filled mattress pad over the cotton one. The type of mattress pad you use will affect the feel and firmness a little as well.
I sleep almost 100% on side. I would guess my setup would be a bit too soft for back sleeping or someone that ways a bit more than me (both seem to be true in your case). Of course it will depend on whether you have back issues and how soft you like it. I don't have back issues that often, and tend to like it a bit on the softer side for comfort.
I would say it is fairly comfortable and supporting for me, without the feeling of sinking in too much over night (like when I have used more than 1" of memory foam). It does feel a little softer after it warms up (in a good way). The additional benefit is I can always make it firmer by taking off 1". So, a good setup might be something a bit firmer than you might like, with 1" increments on top that you can adjust to the right comfort. Some people are able to get it just right with thicker pieces, but that has not been the case for me.
How you layer it will affect the feel as well. For me, putting the memory foam on top and the 19ILD below it gives a bit softer feel.
Bottom line is that almost everyone here ends up with something different, so only your experience and trial and error will get you were you want (if you are fairly picky).
Although I'm about 55lbs heavier than you sandman, it seems we share a lot of sleep habbits. I have no back issues other than those caused from sleeping on a hard stiff surface like my old mattress. Although I love the feel of memory foam, I'm a big guy and generate a lot of body heat quickly, so I'm looking for something that is not heat responsive, thats why I'm looking into latex.
@lynn - I'll surely keep you posted. I'm thinking of getting the 5" firm base instead of the 3". It sure would be easier if I had a shop to test various latex options.
