How thick does a latex mattress need to be?

I am debating on taking the latex I have and putting it on my foundation that I used for the Sealy Truform (Tempurpedic copy).  I now have 5 1/2" latex over my spring mattress, how much more do I need if I am 160-165 lbs, 5' 10 1/2" in order not to bottom out?  Did someone say 9" thick before?  I think I may get samples of 44ILD for the base.

Any suggestions?

Amazingly my back hasn't been hurting with 5 1/2" of latex.  Gasp I now that sounds like a lot, but my springs do not give.  What I want to know is why does the hips (side sleeping) feel no pain and comfortable when I initially lay on it, then hours later, pain city.  Am I the only one with this problem?  It seems like all the complaints here for for lower back.  The only time I had that problem (thank goodness) was when the bed was too soft or too hard.

I sometimes wonder if I will ever get this right.  I still remember Eagle2 (I think) posting that sometimes 80% is the best we can do.  Can't remember exactly what he posted, but I had the layering about 80% good and then I messed with it.  Why can't we get this 100%????

Since no one is answering your original question, I will offer my opinion.   I am 5 ft 10 inches tall and 260 lbs.    I started with 8 inches of "medium" LI latex (ILD unknown) and found that I bottomed out on that setup.    Exchanged it for 8 inches of "firm" (5.5 inches of 40 ILD and 2.5 inches of 32 ILD) which solved the bottoming out issue but was now too HARD.   Then I added 3 inches of 100% natural 24-28 ILD LI latex and find it just about perfect for me.  I am now sleeping on 11 inches of latex plus a little cotton and wool cover on the original mattress.

Since you already have 5.5 inches I would suggest a "base" of firm or extra firm......maybe a 5-6 inch layer.   I suppose you could try 3 inches first since you are lighter than me.  From my experience and what Kimberly has stated, a 36 ILD layer  might be firm enough for most people.   I found 40 ILD to feel like a rock.

i think if you end up putting any more latex in your build you should almost just ditch the springs at some point.  8 inches of quality latex is plenty enough to support just about any body weight without something underneath it.

I assumed he was ditching the springs?    I wouldn't recommend 8-11 inches of latex over springs!

Thanks for the replies.  Yes, I was going to ditch the springs, and put the latex over my old foundation that I bought for the Tempurpedic copy Sealy Truform.  That foundation probably is just a slab right?

I believe 36ILD might be good then?  40ILD is like a rock Mark said? Now if some of my latex is softer than 36 and I want to put it below the firm layer, won't that make it firmer?  My point is I want flexibility and I think some of the O-stock layers are softer than 36ILD, probably 32.  Can I attach an .mp4 video here?  This shows how springy the latex is that I have, or soft.  I push it down compared to the 24ILD I have, I can see the difference; I think anyone could.

Kimberly I agree with you and Sandman to a point.  My left hip has bursitis, but my right hip was fine to sleep on, now it hurts.  As if it is being beaten with a stick.  Not sure why either.  When I lay on my back (which I hate) my back is fine.  This puzzles me and baffles me.  Is it too soft, is it to hard?????
