The DUO Mattress is exceptionally unique in its construction, redefining the way we construct mattresses today. We took the concept of a one-piece mattress and split it into two separate pieces. Now, no longer are the years of restless sleep on a one-piece mattress that has lost its comfort. With the DUO Mattress, you simply replace the comfort layer over time and achieve a refreshed overall feel. #bettersleep #RestAssured
