Hi jdyubergeek,
There is more about the many variables that can affect the durability and useful life of a mattress relative to each person in post #4 here. Assuming that the Overton is a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) and it’s not “on the edge” of being too soft for you then latex is among the most durable materials in the industry and this would be one of the most durable choices you could make.
