Hi Tradernik,
There is really no âdefinitionâ of what a âlatex mattressâ experience means because this is too subjective and different people could have very different opinions about how similar a particular latex/polyfoam hybrid and a particular âall latex mattressâ would feel to them. Both general categories of mattresses have hundreds of different variations that can be very different from each other depending on the specifics of the materials and components inside each of them. There are even some types of high performance polyfoams that are designed to approximate the âfeelâ of latex (see post #2 here).
In terms of âcomfortâ and PPP the only way to know whether any mattress or combination of materials and components is the best âmatchâ for any particular person or how closely it compares to another mattress for them with any certainty (regardless of the specific combination of materials or components inside it) is based on their own careful testing or personal experience.
In terms of durability it would depend entirely on the quality and durability of the materials inside it relative to the person on the mattress. The quality/durability guidelines I generally suggest are in post #4 here and there is much more detailed information about the many factors and variables that can affect the durability and useful life of a mattress relative to a particular person in post #4 here.
Yes ⌠trying to compare different types and blends of latex or mattresses that have different designs and combinations of materials based on ILD alone can be very misleading.
For most people ⌠when you canât test a mattress in person then the options you have after a purchase to âfine tuneâ the comfort or support of the mattress either by exchanging individual layers or components or the complete mattress or returning the mattress for a refund and the costs involved would generally become a much more important part of their personal value equation.
