If you just need a foundation or box spring to go under your mattress - to give your mattress more support or to raise the height - this Slumbercrest Low Profile Foundation has solid wood construction to provide support. When buying a new mattress, it is important to consider buying a new box spring at the same time. Otherwise, your mattress may sag, and you won't get the support you want. The mattress may also wear out sooner, and this will change the way it feels. The Slumbercrest Low Profile Foundation can reduce wear and tear on your mattress and create a more comfortable sleeping surface.
