Hi relay,
[quote]Me: The Soft, Med, Firm was too soft. Firm on top is too firm.
I switched between Med,Firm,Soft and Med,Soft,Firm and settled on Med,Soft,Firm.
This is comfortable for back and side, HOWEVER, I am sleeping more on my side and I find myself turning several times in the night due to pressure on my shoulder that is sunk into the mattress.[/quote]
It would probably be worth trying (from top to bottom) soft/medium/firm. This would be in between the soft/medium/firm and the medium/soft/firm and may allow your shoulders to sink in a little more and would have a little firmer support than the soft/medium/firm.
[quote]I wonder if I could mix a 3" gel 5lb memory foam layer over (2) 3" layers of Med Talalay latex to get the same height as my wifes side?
Anyone know options for 3" gel 5lb memory foam in Twin XL size? I see lots of options for 4lb but it seems that 5lb might be a better product. 7lb might be nice to try too but can’t seem to find anyone selling that as a topper.[/quote]
There is no reason not to try it although it may feel a little bit strange in the middle of the mattress where the memory foam and the latex meet because they have a very different response. Some of the better online sources for memory foam I’m aware of are listed in post #4 here.
