Release any lever that keeps the table from turning. Not every pedestal table has such a lever. If it does, it will be located near the pedestal at the center of the table. Pull out on the lever to release it.
Lift the tabletop off the pedestal. Set the tabletop to one side.
Remove the pedestal from the collar in the floor. Grasp the pedestal and lift straight up. Set it aside.
Set the tabletop into place between the dinette seats. The tabletop will rest on a narrow lip made onto the seats for this purpose.
Arrange the cushions from the back of the dinette seats on the tabletop. Cover the cushions with sheets or a sleeping bag.
