Hi Trinitee64,
Assuming that the materials in a mattress you are considering are durable enough for your body type and meet the guidelines here … the choice between different types and combinations of materials and components or different types of mattresses (see this article) are more of a preference and a budget choice than a “better/worse” choice.
There is more about how memory foam compares to latex in post #2 here but the most reliable way to know which combinations of materials you tend to prefer in “real life” will be based on your own careful testing or personal experience.
I’m looking forward to your comments and feedback after your visit.
