Unspecified (community discusses a DIY/modular mattress setup) DIY mattress (modular latex/pocket coil build)
8/10
Community sentiment is strongly favorable toward modular latex-based mattresses for lifespan, largely because failed comfort layers can be swapped instead of replacing the whole mattress. Multiple users report 7–10+ year durability, with minor caveats like topper replacement cycles and comfort/heat variability by material and climate.
