How long will this value mattress last?

Durability is the honest trade-off, scoring 5.5 out of 10, the lowest axis on this bed. The thin 0.75-inch comfort layer over 884 coils gives less foam to break down, and the coils are thick 13.75-gauge tempered steel that resists sag. The flippable design helps most: rotating and flipping spreads wear across both faces. It is backed by a 10-year warranty and suits lighter-to-average sleepers best over many years.
