How long will this latex mattress last?

It earns a perfect 10 for durability and is backed by a 10-year warranty. The comfort layer is natural latex, the most durable material in mattresses, which outlasts even high-density memory foam and resists the sagging that ends softer foam beds early. Beneath it a thick Serta Foam Core holds its shape with no coils to fatigue, so the medium-firm feel stays true deep into the next decade.
