The King size smart base bed frame is a steel base that
sits up high enough (about 14 inches off the floor)that you do not use a box spring. The smart base
comes un-assembled in a box. No tools are required to put it together. Once built, you simply place
the mattress on top and you are ready to sleep. If you want to add your headboard to the frame, you
will need to purchase the optional headboard bracket set.
