How to Fix a Wobbly Table or Chair Leg in 5 Minutes

The table wobbles every time you put something on it. The chair rocks when you sit. Nothing is broken: one leg sits lower than the others, or a joint has loosened over time.

Both problems take about five minutes to fix, and most fixes need no tools at all.

An uneven leg and a loose joint are the two most common causes of wobbly furniture, and both fix with things you probably already have at home.

Why furniture wobbles

There are two reasons.

Uneven leg. One leg is slightly shorter, or the floor itself isn’t flat. The piece rocks on three points instead of resting on all four.

Loose joint. A chair or table joint has worked itself loose from years of use. The joint shifts instead of holding still.

Each cause needs a different fix.

How to fix it

1. Diagnose first: is it the floor or the furniture?

Move the piece to a different spot on the same floor. If it still wobbles, the furniture is the problem. If the wobble disappears, the floor is uneven, not the table or chair, and a furniture pad under all four legs solves it. Skipping this step is the most common mistake: plenty of “wobbly tables” are actually sitting on uneven tile or warped floorboards.

2. Fix an uneven leg with felt pads or folded cardstock

Stick a felt furniture pad under the short leg. Most packs come with a few thicknesses, so test the piece after each one until it stops rocking. For finer adjustment, fold a scrap of cardstock, slide it under the leg until the wobble goes away, then trace the leg’s outline, cut the cardstock to size, and tape it in place. Add pads one at a time and test after each: if you end up needing two, the first one was probably too thick.

3. Tighten a loose chair joint with wood glue

Pull the loose leg or rung out as far as it goes without forcing it. Coat the inside of the socket and the tenon generously with wood glue, press the piece back in, and wipe off what squeezes out. Wrap a bungee cord or tie a rope around the joint to hold it under pressure, and leave it for 24 hours before sitting on it. Testing the joint early is the mistake that ruins this fix: the glue needs the full 24 hours to bond, and putting weight on it sooner breaks the joint loose again.

4. Adjustable feet: rotate them level

Many modern tables and shelving units have threaded rubber feet built to compensate for uneven floors. Check under each corner: if a foot screws in and out, turn it clockwise to raise that corner or counterclockwise to lower it, a quarter turn at a time, testing after each turn, until all four legs sit flat. No tools needed. Turning a foot too far in one go is the usual mistake, since it just trades one wobble for another.

Common questions

How often do furniture joints loosen?

It happens gradually, from years of daily use rather than on any fixed schedule. Check your chairs once a year: a joint that has just started to move is much easier to fix than one that has been rocking for a long time.

What happens if you ignore a wobbly chair?

The joint keeps loosening every time someone sits down. Eventually the leg pulls free of the frame completely, and what would have been a five-minute fix turns into buying wood glue and clamps anyway, or replacing the chair.

Can I use super glue instead of wood glue for furniture joints?

No. Super glue turns brittle under repeated pressure and cracks. Wood glue stays slightly flexible, bonds specifically to wood fibers, and holds up under the weight and movement a chair joint takes every day.

What if the whole frame of a chair is loose, not just one joint?

Take the chair apart as far as you reasonably can, apply wood glue to every joint, put it back together, and use several bungee cords or ratchet straps to hold the whole frame under pressure for 24 hours. Same idea as fixing one joint, just more of it at once.

Do felt pads stay in place under furniture legs?

On flat-bottomed legs, yes: the adhesive backing holds well. On rounded or uneven leg bottoms they can shift over time, and clear furniture gripper cups work better in that case.

Pro tip

After you fix a wobble, dab a small spot of colored nail polish on the bottom of the leg you fixed, or on the foot you adjusted. Next time it rocks, or if you want to check your work later, you’ll know exactly which leg to look at instead of testing all four again.
