Noise Reduction for Office Chairs

The following measures can be taken to reduce noise from office chairs:

1. Use Chair Foot Pads
   Choose foot pads with sound-dampening, wear-resistant, and anti-slip designs. The material should form a buffer layer between the chair and the floor, converting sharp friction sounds into soft muffled noises. For example, rubber or silicone foot pads, after special treatment, can maintain stable performance for a long time and are suitable for common floor types such as wooden floors and tiles.

2. Replace the Chair or Casters
   If the chair has been used for a long time or shows significant structural wear, replacing it with a new one of good quality and sturdy structure is the fundamental solution. If only the casters are worn out, replace the nylon casters with quiet PU casters. Their material can effectively reduce friction sounds with the floor, especially suitable for hard floor environments.

3. Lubrication
   Lubricating the metal connections of the chair (such as hinges and slide rails) can eliminate abnormal noises. Apply a small amount of cooking oil or professional lubricant evenly to the noisy parts, avoiding excessive application that may leave oil stains. For specific models (such as Sihoo M18), you can use WD-40 Blue Can Regular (equipped with a small straw) to spray the bearing connections. It combines the functions of eliminating friction noise, lubrication, and rust prevention.

4. Check and Tighten Screws
   Abnormal noises from the chair may be due to loose screws. Regularly check the screws at the connections of the backrest, seat cushion, armrests, etc., and tighten them one by one using tools, paying special attention to the fixation of adjustment mechanisms (such as lifting rods and reclining devices).

5. Adjust the Chair Structure
   Fine-tune the angle and tightness between the backrest and seat cushion, or adjust the height of the armrests to reduce friction and looseness between components. For example, if there is noise at the connection between the backrest and seat cushion, try adjusting the reclining resistance to a moderate level.

6. Add Adhesive Paper Gaskets
   Adding adhesive paper gaskets between the hole walls of metal connectors and screws, or at the contact surfaces of components, can fill gaps and reduce friction. This method is suitable for screw-fixed areas or the joints of detachable components.

7. Handle Specific Issues
   If the chair is a specific model (such as Sihoo M18) and the abnormal noise mostly comes from the bearing connections, prioritize using WD-40 for spraying treatment. If there is abnormal noise from the lifting of the gas rod, check the sealing of the gas rod and contact after-sales service for replacement if necessary.

By conducting systematic inspections and targeted treatments, the noise interference during the use of office chairs can be effectively reduced.
