I'm trying to understand what mattress features are most important for long-lasting comfort and durability.

Specifically, I would like to know:

- How different layers and materials affect longevity

- What mattress systems (e.g., pocket springs vs foam) perform better over time

- What features experienced users recommend for everyday use

I found this overview of different mattress options and specifications here:

Looking for technical explanations or real experience that could help someone choose the most suitable mattress based on long-term performance.
