"DeLuxe Firm" mattresses provide maximum support without sacrificing a comfortable sleeping surface. "DeLuxe Firm" does not necessarily equate to "hard". By using one of the industry's firmest inner spring, adding double edge guard supports, a steel grid and a firm insulator pad, maximum support is attained. Then by adding a build of a variety of upholsteries we can provide very different levels of comfort and you will get the best of both worlds - maximum support with varying comfort.
