Does the Office Chair Make Noise When Leaning Back?

The office chair may make noise when leaning back, and the common causes and specific analyses are as follows:

1. Loose connecting components
The backrest, armrests, base, and five-star feet of an office chair are fixed with screws or clips. After long-term use, the screws may become loose due to vibration or frequent adjustment. When leaning back, gaps form between the loose components, and metal or plastic parts collide or rub against each other, producing a crisp 'click' or 'creak' sound. For example, when the connecting screws between the base and the five-star feet become loose, the backward movement will cause direct contact between metal parts, resulting in a noticeable noise.

2. Lack of lubrication in moving parts
Chairs with a reclining function contain core moving parts such as metal springs and rotating shafts inside. If not maintained for a long time, the lubricating oil may dry out or become contaminated with dust, leading to direct dry friction between metals. This friction is particularly evident when the chair is reclined, producing a continuous 'squeaking' sound. Especially in low-temperature environments, the increased viscosity of the lubricating oil may make the noise more pronounced.

3. Noise from the gas lift
The gas lift is a key component for the height adjustment and reclining of an office chair, filled with high-pressure nitrogen gas inside. When the chair is reclined, the gas inside the gas lift produces a slight airflow sound due to compression or expansion. If the gas lift has poor sealing or manufacturing defects, the airflow sound may be more noticeable, but it is usually a normal phenomenon and there is no need to worry excessively.

4. Improper adjustment of the reclining tension
Many office chair bases are equipped with knobs to adjust the reclining tilt force. If the knob is adjusted too tightly, the mechanical structure may exceed its designed load-bearing capacity during reclining, resulting in a sense of obstruction or abnormal noise between components. For example, when the spring is excessively compressed, metal fatigue or deformation may cause a 'creaking' sound. In this case, the knob should be appropriately loosened to restore smooth reclining.

Summary
The abnormal noise when an office chair is reclined is mostly caused by mechanical structure problems and can be solved by tightening screws, adding lubricating oil, checking the sealing of the gas lift, or adjusting the reclining tension. If the abnormal noise is accompanied by chair wobbling or functional failure, it is recommended to contact a professional repair technician for inspection and repair to avoid further damage caused by self-disassembly.
