How long does a mattress last?
In short
Lifespan depends on core material: many foams last about 6–8 years, pocket sprung and hybrids often 7–10, and latex cores commonly 8–12 under normal use. Sag, broken support, or persistent discomfort with an aged mattress are replacement signals.
More detail
Foams soften via foam wear and oxidation; steel coils take permanent set; latex ages through permanent flattening. Maintenance (rotate, protector, correct base) affects realised life. See material lifespan tables for detail.
