How long will this mattress last, and is it durable?

We rate durability a candid 6 out of 10, Fair for its class. A 6-inch all-foam build has less material between you and the base than a tall hybrid, so the comfort layer will soften sooner under years of nightly use. It is backed by a 10-year warranty and a high-density core built to outlast the surface. As a guest-room, youth, or budget primary bed it holds up well; a heavier nightly sleeper should expect softening over a decade.
