A floor lamp requires stability, or it falls easily, and a falling floor lamp could injure a nearby pet or child, or create a flying glass hazard when the lamp's bulb or glass or ceramic shade shatters on impact. Examine your unstable floor lamp for repair potential before discarding it for a more stable model.
Turn off your lamp and remove the plug from its socket. Allow the lamp and the bulb inside it to cool completely before proceeding.
Remove the bulb once it has completely cooled and set it aside. Removing the bulb at this stage of the repair lessens the chance that you'll damage the bulb or its filaments during the repair process.
Lay down your lamp to get access to its base, located on the bottom of the lamp. Peel back the felt at the bottom of the lamp or pry off the cover of the base using a flathead screwdriver. Remove any screws with a Phillips or flat head screwdriver, if screws are holding the base's cover to the base.
Grab the cord that protrudes from the bottom of the base and rethread it through the proper side opening if it has come away from its intended path.
Tighten the bolt that connects the lamp's post to the base, using your wrench; when this bolt is loose, the post wobbles because it isn't firmly connected to the base. Wrap the bolt in tape before tightening it if the bolt it stripped.
Reattach the base cover using screws or by pressing the cover or felt back over the base's bottom. Stand your floor lamp onto its base and check for wobbling. Try gluing a small, round furniture leg pad on the one side the floor lamp leans. Add additional pads until the lamp is stable when standing.
Screw your light bulb back into the lamp and return the lamp to its previous location to complete the repair.
