A wobbling over armchair table is frustrating, but it's usually a quick fix rather than a reason to replace the table. Before you give up on it, work through these five checks. Most people find the culprit by fix number three.

Check the basics first (fixes 1 to 3)
The most common causes of over chair table wobbling come down to three things that are easy to miss during everyday setup. Work through these before anything else.
Fix 1 — Are the castors locked?
This is the most overlooked cause of wobbling, and the easiest fix. Most over chair tables roll on four castors (small wheels) so you can move them around easily. Each castor has a small brake tab you press down with your foot to lock it in place.
If even one castor is unlocked, the whole table can shift under load. Get down and check each wheel. Press each brake tab firmly until you feel it click, then try the table again.
Not sure whether your table has locking castors? Check the product page for your model. Our over armchair table range includes the specifications for each model.
Fix 2 — Are the base legs fully extended and sitting flat?
Over chair tables have a U-shaped or H-shaped base that slides under and around your chair. That base often has adjustable feet or splayed legs that need to be fully extended and sitting flat on the floor.
Partially extended legs create an uneven contact point with the floor. Even a small gap under one leg is enough to cause rocking. Extend each leg to its full position, then place your hand under each foot to confirm all four are making solid contact.
Also check that the base is positioned correctly under the chair. If it's resting against the chair legs rather than sliding cleanly underneath, it will tilt.
Fix 3 — Is the height column lock fully engaged?
The height-adjustment column is a common source of wobble. Most over chair tables have a telescoping column with a twist lock, a lever, or a pin that holds the height once you've set it.
If that lock isn't fully engaged, the column can slip or rock slightly under the weight of anything placed on the tabletop. Lower the table to its minimum height, then re-raise it to your preferred position and tighten the lock firmly. Give the tabletop a gentle push side to side. No movement means the lock is holding.
What to do when the floor or load is the problem (fixes 4 and 5)
If the first three fixes didn't solve it, the issue may be the surface underneath the table or the way things are sitting on top of it.
Fix 4 — Check for uneven flooring
Carpet joins, floor transitions (where carpet meets tiles), or a slight bow in floorboards can make an over chair table rock even when it's correctly assembled. The table isn't broken — it's just on an uneven surface.
The simplest fix is to reposition the table a few centimetres in any direction until all four castors sit on a consistent surface. On carpet, press each castor down firmly so the wheel sits below the carpet pile rather than resting on top of it.
For persistent rocking on uneven hard floors, thin rubber furniture pads placed under any castor that's lifting can compensate. These are inexpensive and available from most hardware stores. Alternatively, locking the castors first (Fix 1) often reduces the effect of minor floor variation significantly.
Fix 5 — Check the weight distribution on the tabletop
Over chair tables are designed for light daily use: a meal, a drink, a book, a tablet. They're not built for heavy or unevenly distributed loads.
If a heavy item — a laptop, a large drink bottle, or a plate stacked with food — is sitting towards one edge, it shifts the centre of gravity and causes the table to tip or rock. Slide everything to the middle of the tabletop and spread items evenly. Most standard over armchair tables are rated for around 5 to 10 kg, so check your model's specifications if you're unsure.
Our article on the best over armchair tables in Australia covers what to look for in a stable model if you're finding your current table is regularly close to its limit.
When wobbling means the table needs replacing
If you've worked through all five fixes and the wobble is still there, it's worth taking a closer look at the table itself.
Signs that the table has reached the end of its useful life include:
- Visible cracks or bending in the base frame or column
- A height lock that no longer holds position even when fully tightened
- Loose or wobbly joints that move independently of each other
- Castors that no longer lock or roll cleanly
A structurally compromised over armchair table is a safety risk. If a hot drink or a meal tips because the table gave way, the consequences can be serious — particularly for someone with limited mobility.
A replacement table doesn't need to be expensive. If you're unsure which model to choose, our guide on how to choose the best over armchair table in Australia walks through the key things to look for, including base design, height range, and tabletop size.
Most wobbles are fixable. But if the frame is damaged, replacing sooner rather than later is the right call for your peace of mind.
Key takeaways
- Check the castor brakes first, as one unlocked castor is enough to cause rocking
- Make sure all base legs are fully extended and making contact with the floor
- Re-engage the height column lock firmly if the table shifts when loaded
- Reposition the table if it's sitting on an uneven surface or a floor transition
- Keep heavier items centred on the tabletop to avoid tipping
- Replace the table if the frame or column is visibly damaged or the locks no longer hold
