How durable is this mattress over the long run?

Durability is a standout, scoring a perfect 10 out of 10. The reason is the materials: natural latex outlasts even high-density memory foam before forming a body impression, and the 2,014-coil core uses thick 13.75-gauge tempered steel that resists sag far better than thin budget wire. With CertiPUR-US certified foams and a 10-year warranty behind it, this Lux Estate Euro top is engineered to keep its shape across many years rather than softening in a season.
