Office Chair Squeaking

The constant squeaking of an office chair may be caused by loose screws, worn or rusty gas lift rods/height adjustment rods, cracked or loose five-star bases (five-claw bases), lack of lubrication in the rocking base/reclining pivot, foreign objects stuck in the casters or damaged bearings, or broken cushion/backrest wooden boards/frames, and can be repaired or the problem located through specific methods.

1. Loose Screws
   The screws at the connections of the chair's backrest, seat, armrests, and base are prone to loosening under long-term stress, resulting in a "creaking/squeaking" sound when leaning forward, backward, or side to side, and no sound when stationary. The sound is often located beneath the seat, on the backrest connecting steel plate, or at the armrest base. To repair, turn the chair over and tighten all visible screws one by one using a cross or hex key, focusing on the connections of the backrest, seat, armrests, and base.

2. Worn or Rusty Gas Lift Rods/Height Adjustment Rods
   The gas lift rod (the central metal column) can become dry and friction-prone due to long-term weight bearing or dust accumulation, emitting a "click, squeak" sound during height adjustment and making a sound with slight shaking when seated, with the sound coming from the center. To repair, spray WD-40, sewing machine oil, or grease onto the gas lift rod and move it up and down several times to lubricate. If the noise is severe, the gas lift rod should be replaced directly.

3. Cracked or Loose Five-Star Bases (Five-Claw Bases)
   Plastic or nylon feet are prone to aging and micro-cracking, while metal feet may suffer from fatigued welds. Slight deformation under weight can produce a cracking sound, with a "clunk" sound when sitting down or getting up. In severe cases, the footrest may deform, posing a safety hazard. To repair, if the gas lift rod is severely noisy, it should be replaced, and if the five-star base is cracked, it must be replaced.

4. Lack of Lubrication in the Rocking Base/Reclining Pivot
   The reclining function of an office chair relies on springs and pivots. Lack of lubrication can cause dry friction, resulting in a piercing, continuous creaking sound when reclining or rebounding, located at the large metal plate beneath the seat. To repair, spray WD-40, sewing machine oil, or grease onto the reclining pivot and move it up and down several times.

5. Foreign Objects Stuck in the Casters or Damaged Bearings
   Hair, thread, or worn internal bearings in the wheels can cause a "rustling/creaking" sound when pushing the chair, and the chair may also make a sound when rotating in place. To repair, remove the wheels, cut away any entangled objects, lubricate with oil if the bearings are dry, and replace the wheels if damaged.

6. Broken Cushion/Backrest Wooden Boards/Frames
   The internal frames of mesh or fabric chairs can age and crack, emitting a wood or plastic cracking sound under pressure, posing a safety hazard. It is recommended to replace the chair directly.

Quick Methods to Locate the Source of the Squeaking Sound:

• If the backrest creaks when shaken by hand without sitting, check the backrest screws or connecting frame;
• If it creaks during height adjustment when seated, check the gas lift rod;
• If it creaks when reclining without leaning back, check the base pivot;
• If it creaks when rotating in place, check the wheels or five-star base;
• If it creaks when twisting side to side, check the seat fixing screws.
