The dominant BIFL claim is that latex layers—especially a latex base—hold up for a decade or more, while the top comfort layer (toppers) may need replacement roughly every 10 years. Several comments contrast modular latex/coil builds with all-in-one mattresses, arguing that when one layer fails in a modular system, only that layer needs replacing instead of discarding the whole mattress. Users also report failure modes common to non-modular foams: sagging in memory foam after years and heat retention concerns. A pocket-coil base is repeatedly cited as improving edge/middle support, and some builders use split firmness by dividing layers for fine-tuning without replacing the whole assembly.
