8/10
Community reports favorable long-term outcomes for latex-forward, modular/split-layer mattress builds, with users repeatedly citing multi-year durability. Failure mode is usually comfort-layer sagging/softening, but replacement can be limited to a top layer rather than the whole mattress, improving practical longevity.
