How to Repair Office Chairs
The repair of office chairs requires selecting the appropriate method based on the specific type of fault. Common faults and repair steps are as follows:
I. Minor Wear Repair for Leather Executive Chairs
If there are minor scratches or wear on the leather surface, cleaning is required first. Spray a multi-functional cleaner onto the damaged area and gently wipe it with a soft cloth or sponge along the grain direction to remove surface stains and aged cuticles. After cleaning, allow it to dry naturally and avoid direct sunlight to prevent the leather from becoming brittle. If cracks appear at the worn area, apply a special leather repair paste, evenly fill the cracks with a scraper, and after drying, lightly sand it until smooth. Finally, spray a leather conditioner that matches the original chair color to restore shine and waterproofing.
II. Repairing an Office Chair That Leans to One Side
Check the Wheel Status
Place the chair upright and observe whether each wheel foot makes even contact with the ground; invert the chair and check for any broken, deformed, or stuck wheels. If the wheels are damaged, replace them with matching models:- Contact the manufacturer with the chair model to order original wheels;
- Remove the old wheels (insert a flat-head screwdriver into the gap between the wheel foot and the chair base as a lever, slowly pry until loose, and then pull out), and take them to an office supplies store to match a replacement set with the same axle shape and size.
Lubricate the Base Sockets
Spray a small amount of WD-40 spray lubricant (or apply a pea-sized amount of Vaseline) into each chair base socket, insert a straw to precisely aim inside the socket, and quickly spray for 0.5 seconds to avoid excessive oil seepage.Install New Wheels
Align the caster stem with the base socket, gently push it in by hand until it is initially seated, and then lightly tap the top of the wheel or near the stem base with a rubber mallet to ensure it is fully seated. If the wheel design allows, tap the stem base to distribute the impact force and avoid damaging plastic components.Test and Further Troubleshoot
Invert the chair and rotate it to test the flexibility of the new wheels. If it still leans, check if the seat plate is deformed: place the chair on its side, locate the metal seat plate (usually a square black steel plate) that connects the seat cushion to the chair legs, and observe for any breaks or cracks at the welds. If the seat plate is damaged, contact a professional for repair or replacement.
III. Disassembling and Repairing a Lifting Chair/Gaming Chair (Leaning Sideways or Unable to Lift)
Disassemble the Chair Structure
Invert the chair and place it on the ground, use a screwdriver to remove the fixing screws between the bottom tray and the seat cushion, and separate the seat cushion, chassis, gas lift, and chair legs.Handle Chassis Faults
Hold the chassis upside down with one hand and tap the edge of the chassis at specific positions with a rubber mallet (or tap it lightly with an iron hammer after padding it with a towel) to separate the chassis from the gas lift. If the chassis is deformed and causing sideways leaning, replace it with a new one.Repair the Gas Lift
If the chair cannot lift, the gas lift may be leaking or stuck. Invert the chair and tap the bottom of the gas lift flatly with a hammer from the side (avoid using the sharp corner of the hammerhead) to force the internal piston to reset. Be sure to choose a gas lift with SGS or TUV certification, as inferior products may pose an explosion risk.Replace the Wheels
Pull out the old wheels directly and forcefully; if they are stuck, use a screwdriver to assist in prying the edge of the wheel foot. When installing new wheels, ensure the axle is fully inserted into the socket to avoid looseness that could cause sideways leaning.
Repair Tips: Wear gloves before operating to prevent scratches. If it involves internal springs or complex structures, it is recommended to contact a professional repair person for handling.
