Why do some stacking chairs rock or wobble, and how do I fix it?

Stacking chair rocking or wobbling is caused by: uneven leg lengths or bent legs (from impact damage), worn or missing floor glide caps (one leg shorter than others due to missing cap), warped floor (not the chair's fault - a chair level on flat floor is fine), or loose frame joint welds. Fix: replace missing glide caps first (the simplest fix). For minor uneven leg lengths, self-leveling glide caps (adjustable height furniture feet) can compensate. Significantly bent frames are a safety issue - replace the chair rather than trying to bend it back. For rocking on a genuinely uneven floor, anti-rocking glides or floor levelers under the seating arrangement help. FindOfficeFurniture.com - 888-719-4960.
