We've had our Duxiana mattress for over 20yrs and I love it. However, I have a Temperpedic neck pillow which they say lasts 5 yrs. I'm on my second pillow. I would think the mattress might have a longer lifespan but I wouldn't plan for more than a decade. What does Temperpedic say? They were upfront about my pillow. Of course, they wanted to sell me another one.
