Albert, You move the flippen nightstand!!!!
In my case, Helen usually has the clock and lamp on the bed without unplugging (My clients don't like flashing clocks) and the front 2 legs or corners on sliders, If I cant shift from side to side, I will pull out to the end of the bed so I have room to satisfactorily clean that area.
Slide back and Helen will place on Tabs or Blocks when she removes the sliders with the Lift Buddy and the Tabber. (Your Welcome Gary)
