Hi NiteLife,
Bedsetc is owned by members of the same family as Electropedic and in my conversations with them I have found them to be helpful, open, and knowledgeable and to the degree possible they would certainly provide you with the layering of their mattresses (including the Electropedic models).
It’s always important to make sure you know all the layers in a mattress so you can make meaningful quality and value comparisons with other mattresses that are available to you but they are one of the better “possibilities” in Los Angeles which is why they are included in the Los Angeles list here.
As you are discovering … soft and firm is relative to the person and in the case of latex it can be surprising because even firmer latex is very “point elastic” which means it mirrors the shape of the body very well and is very good at re-distributing body weight and relieving pressure. This is also the reason why more objective and specific testing for PPP (Pressure relief, Posture and alignment, and Personal preferences) is more accurate than any “theory”.
