Talalay Core or Pocket Coil for softness?

First, I would like to say thanks for the website! Its been VERY helpful.

Any idea what would be a softer experience?

Soft 6" Talalay core with 3" Soft Talalay top layer

or

Hybrid Pocket Coil 8 1/2" with 3" Soft Talalay top layer

*My wife and I are both thin (145 and 120lbs) and sleep mostly on our sides.

Hi Sleepless-in-Cali,

If the comfort layer and the cover was exactly the same in both mattresses it would depend on the specifics of the pocket coil and how it compared to the Talalay support core. If they are both sold at the same store then they should be able to tell you which one most people would find softer (although this would also be somewhat subjective and different people may have different opinions about which one was softer) but if they are sold at different stores the only way to know would be based on your own personal testing or experience because innersprings and latex have a different ā€œresponse curveā€ and ā€œfeelā€ (see post #28 here).
