How long will this mattress last?

Durability is its softest area, scoring 5.6 out of 10, because it runs a thinner comfort layer over 884 coils versus the 1800 in Springwall's premium models. Two things help: thick 13.75-gauge tempered steel coils that resist sag, and the two-sided flippable design, which spreads wear across both surfaces and can roughly double usable life. It is backed by a 10-year warranty and favours lighter-to-average sleepers long term.
