Office Chair Noise Repair

Office chair noise repair can be carried out following these steps:

Step 1: Identify the source of the noise

1. Check the connecting screws: Focus on the connection points of the backrest, armrests, base, and chair legs. Shake them with your hands to feel for any looseness. Loose screws may be the direct cause of the noise.
2. Locate the noise by listening: Sit on the chair and rock it slowly, listening closely to different parts. If the sound comes from under the seat cushion, it may be an issue with the base's rotating shaft or the gas lift. If it's near the chair legs, it could be due to friction between the chair feet and the floor or a loose tenon.
3. Inspect special components:
   • For chairs with a rocking and reclining function, check the metal springs and rotating shafts. Long-term use may lead to spring fatigue or shaft wear.
   • For lift-and-rotate seats, determine if there is any noise from the lift rod, which may be due to aging internal seals or insufficient lubrication.
   • Pay attention to the contact surface between the chair feet and the floor. If the floor is uneven or the chair feet are worn, noise may be generated due to friction.

Step 2: Tighten screws and repair worn holes

1. Tighten loose screws: After finding loose screws, use an appropriate screwdriver or wrench to gradually tighten them clockwise. Avoid over-tightening to prevent stripping the threads.
2. Repair worn screw holes: If the chair still wobbles after tightening the screws, the screw holes may be worn. In this case, use a toothpick or a thin wooden stick dipped in white glue to fill the screw holes. After the glue dries (about 2-4 hours), tighten the screws again to enhance the fixing effect.
3. Handle loose tenon-and-mortise structures: For old-fashioned wooden chairs with loose tenons, first clean off the old glue. Apply white glue to the surface of the tenon and knock it back into place. Secure it with a rope or a clamp. After the glue has completely dried (about 12 hours), remove the fixing device.

Step 3: Lubricate metal components

1. Lubricate rotating shafts and lift rods: For the rotating shafts of the chair base with a rocking function and the lift rods of lift-and-rotate seats, apply an appropriate amount of lubricating oil (such as WD-40 or silicone-based lubricating oil). Lift or recline the chair several times to evenly distribute the lubricating oil.
2. Clean and lubricate the slide rails: If the slide rails of the office chair make noise, first use a vacuum cleaner to remove dust and debris from the tracks. Then, spray a penetrating lubricant (such as WD-40) and slide the seat back and forth to cover the track surface with the lubricant.
3. Treat the lift column: Apply lubricating oil evenly around the lift column to solve noise or resistance problems caused by friction. After application, lift the chair multiple times to disperse the lubricating oil.

Precautions: Before operating, confirm the chair's structural type (such as screw-fixed, tenon-and-mortise, or gas lift design) to avoid damage from incorrect disassembly. If the noise persists, it may be due to aging internal parts (such as a leaking gas lift). It is recommended to contact a professional repair technician to replace the parts.
