My chair tilts unevenly. Is the base broken or just loose?
A wobbly chair usually has one of three causes. Here's how to diagnose and fix each:
| Problem | Signs | Fix |
|---|---|---|
| Loose Screws/Bolts | Chair wobbles at connection points | Flip chair, tighten all visible bolts with Allen wrench or screwdriver |
| Worn Casters | One wheel smaller or damaged | Replace individual casters (universal fit, $10-20 each) |
| Bent Base Star | Base visibly uneven on floor | Replace the entire 5-star base (match gas cylinder size first) |
| Gas Cylinder Issue | Cylinder moves within base | May need cylinder replacement if base socket is worn |
Quick Test:
Remove casters and set base on flat surface
If base rocks, it's bent—replace it
If base is flat, check caster heights
Still wobbly? Tighten all chair-to-mechanism bolts
Most wobbles are fixed by simply tightening bolts or replacing one worn caster.
