Multiple brands mentioned (e.g., Talalay latex, pocket coil bases) Mattress (DIY modular latex / coil build)
8/10
Reddit consensus favors modular latex (often Talalay) and/or pocketed coils because individual layers can be replaced instead of discarding the whole mattress. Lifespan reports commonly reach ~8–10+ years for latex bases/components, with complaints mainly about heat retention (especially memory foam) and occasional sag in cheaper foam builds.
