I’m actually going for the memory foam/latex hybrid feel. I like dead feel of memory foam and the push back of latex. I think I’m on the right track with the exception of the base.
I used the firm latex topper on top of the poly. I also tried layering my old 3" memory foam on top of the latex over the poly foam base. I didn’t using my new 2" memory foam because it was in the other room and I was too tired to carry that back and forth. I prefered both configurations over my current configuration of memory foam over latex over latex. Out of those two, I prefered latex over topper rather than the memory foam over latex over topper. The 3" of memory foam was thick enough that I couldn’t really feel the latex below it.
Thank you for your advice.
