Detachment of the Bottom of an Office Chair

The repair method for the detachment of the bottom of an office chair should be selected based on the type and extent of the detachment. Here are some common repair steps:

I. Detachment of the Bottom Fabric or Padding

1. Adhesive Method: If the detached area is small, first clean the bottom plate and the back of the fabric to remove old adhesive or debris. Apply automotive interior adhesive, liquid adhesive, or white glue evenly, press firmly to adhere, and let it sit until fully cured. If the fabric cannot be lifted, use a syringe needle to inject the adhesive into the gap.
2. Nail and Button Method: For areas that need reinforcement, use special repair nails or buttons to pierce through the fabric and into the bottom plate, fixing multiple points at intervals to enhance stability.
3. Fabric Replacement: If the fabric is aged and powdered (e.g., cheap non-woven fabric that crumbles after 3-5 years), thoroughly remove the old adhesive and debris. Choose thickened non-woven fabric or high-density polyester fabric, with a size 2 cm larger than the bottom frame for edge wrapping. Use soft universal adhesive to paste, ensuring the edges are flat.

II. Detachment of Bottom Structural Components (e.g., Separation of Wooden/Metal Bottom Plate from the Frame)

1. Small-Scale Detachment: After cleaning the connection, apply strong adhesive (such as AB glue) to the detached surface, align it, press firmly, and let it sit for more than 24 hours until fully cured.
2. Large-Scale Detachment or Ineffective Adhesive: Use self-tapping screws to fix. Align the detached part and tighten the screws; if there are no screw holes on the original chair, first drill holes at the connection with an electric drill, then install the screws to ensure structural stability.

III. Detachment at the Connection between the Chassis and the Pneumatic Rod

1. Loose Screws: Use a screwdriver to tighten the screws at the connection between the chassis, pneumatic rod, and seat to prevent further detachment due to looseness.
2. Damaged Chassis: If the chassis is cracked or deformed, contact the manufacturer to replace it with a new one. Do not attempt to repair it yourself to avoid safety hazards caused by insufficient structural strength.

IV. Preventive Measures

1. Regular Inspection: Check the bottom connections monthly for looseness, and tighten the screws or repair small-scale detachments promptly.
2. Proper Usage: Avoid vigorous shaking, sitting heavily, or dragging the chair to reduce friction between the bottom fabric and the ground.
3. Choose High-Quality Products: Prioritize purchasing office chairs with steel chassis, high-density polyester fabric, or leather padding to reduce the risk of detachment.

V. Seek Professional Help

If the detachment involves broken internal springs or bands, large-scale cracking of the leather, or if the chair remains unstable after self-repair, it is recommended to contact furniture repair professionals or the manufacturer to replace the parts.
