Advice on "layering" for a hybrid mattress

Hello
Is it sensible to put pocket coils directly on top of, or beneath, latex? Or is one better off having a layer of some sort – even if a sheet of fabric – as a divider between coils and latex?
Thank you.

The coils have an extra layer of fabric on top and bottom which you can’t see in the promo pictures provided by Leggett and Platt. They just show how the coils are laid out. It is not necessary to add anything below or on top of the coils and the latex can go directly onto them. Let me know if you have any other questions.
