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%????
