Fix a wobbly wooden chair
A chair that shifts when you sit down has joints where the glue has given out. Adding glue to the gap is tempting, but it rarely holds for long. Taking the loose joints apart, cleaning them and regluing them does. A dead-blow or rubber mallet helps here, since it knocks joints apart without denting the wood.
How chairs hold together
Wooden chairs are held together mostly by glue, with the rungs and rails pushed into holes in the legs. Once that glue dries out, the joint shifts a little every time someone sits down, and the hole slowly wears bigger. The repair below takes the loose joints apart, cleans them, and glues them back properly.
Why chairs loosen
Old glue dries out and lets go.
Movement slowly enlarges the holes.
Some chairs use screws or corner blocks that loosen.
Wood shrinks and swells through the year.
| Joint type | How to tell | Fix |
|---|---|---|
| Round peg in a hole | Rungs and rails pushed into drilled holes | Tap apart, clean, reglue, clamp. |
| Corner blocks under the seat | Triangular blocks screwed in the corners | Tighten or replace the screws. |
| Metal bolts and nuts | Visible bolt heads on the legs | Tighten the bolts. Add a thread locker if they keep loosening. |
| Glued joint that won't come apart | Tight joint, but it still flexes | Inject glue as a short-term fix, or see a furniture repairer. |
Reglue the joints
- Find the loose jointsFlip the chair and wiggle each rung and leg. Mark every joint that moves.
- Tap the joint apartGently tap loose joints apart with a rubber mallet. Only separate the loose ones.
- Scrape off old glueClean old glue from the peg and the hole with a utility knife. New glue won't bond to old glue.
- Glue and reassembleBrush glue inside the hole and on the peg, then tap the joint back together with the mallet.
- Clamp overnightWrap a strap clamp around the legs, snug it, wipe off squeeze-out with a damp rag, and let it dry overnight.
Watch it done
- No leg or rung moves when you wiggle it
- The chair sits steady without rocking
- No dried glue squeeze-out at the joints
Still wobbly? Tighten the screws in the corner blocks under the seat.
If a joint is still loose
If it's a table that wobbles, see the guide for fixing a wobbly table.
If a peg is loose in its hole even after cleaning, wrap a thin wood shaving or a layer of glued fabric around it for a snugger fit.
Check the corner blocks under the seat. Tightening their screws often fixes a wobble on its own.
What a pro typically charges (a rough estimate; prices vary by area): A furniture repair shop typically charges $50–$150 per chair.
