Unspecified (component-based DIY mattress using latex layers and optional pocket coil base) DIY modular mattress (latex core + replaceable toppers/pocket coil base)
8/10
Community reports multiple multi-year to decade-range lifespans for latex-based modular mattress builds, largely because worn comfort layers can be replaced without discarding the full mattress. Memory-foam and all-foam builds are more frequently associated with early sagging/heat complaints, lowering BIFL confidence.
