Glass-topped tables are sleek and complex, however, like any piece of furniture, time and wear may toss them a bit out of whack. Few things are more annoying than a table which rocks when you lean on it, along with a table which wobbles is more likely to cause leakage. Fixing a wobbly table is not complicated, though you may have to try several procedures before finding the one which works for you.
Ensure that the glass top is securely seated in its framework or on its foundation. If it is not, reseat it by moving and lifting the glass till it settles back to position.
Move your table a few inches in each direction to see if the wobbling is caused by an irregular floor rather than an issue with the glass table. This works equally well on rectangular, square, round or oblong poles with four legs. Alternatively, rotate the table when it sits on a single, base base.
Examine the table legs to see if the screws or bolts which hold them in position have come loose. Tighten all screws or bolts, using a screwdriver or wrench.
Lift each leg a couple of inches from the floor and make sure that any cushioned or nonslip pads which needs to be connected to the bottom remain in place. These may fall off as soon as the table is moved, making the table wobble. Buy replacements at your local home improvement store.
Prop up whichever leg or portion of this pedestal is not sitting solidly on the floor, using a little piece of folded felt or cardboard. Once the table is stable, gauge the thickness of your shim and then buy a premade, nonskid wedge to replace your temporary repair.
