Office Chair Disassembly Guide

Disassembling an office chair requires step-by-step operations based on its specific type and structure, with core points including identifying key components, disconnecting connections, paying attention to safety hazards, and adopting targeted handling for different materials and functions.

I. Disassembly Points for High-End Electric Office Chairs (e.g., Livorno S02 Executive Chair)

1. Functional Module Separation: These chairs integrate an electric adjustment system (headrest, backrest, leg rest, seat cushion) controlled by four independent motors. Before disassembly, disconnect the power supply to avoid short circuits or accidental motor activation.
2. Connection Wire Handling: There are usually three connection wires (power wire, signal wire, heating module wire) between the backrest and seat cushion. Use professional tools to mark and disconnect each wire individually to prevent confusion and functional abnormalities.
3. Airbag and Heating Module Removal: The massage function relies on two sets of five airbags. First, release the air pressure (via an exhaust valve or manual pressing); the lumbar heating module blows air through small holes, so turn off the heating function and allow it to cool before disassembly to avoid burns.
4. Fabric and Filling Separation: The contact surface uses European imported top-grain leather. During disassembly, use a hot air gun to soften the glue and peel it off gradually from the edges; the PVC artificial leather part can be cut directly, but retain the complete structure for future assembly reference.

II. Hazards and Precautions for Disassembling Low-Quality Office Chairs

1. Structural Safety Risks: Low-priced products have thin chassis plates and poorly welded chair legs. During disassembly, wear safety goggles and gloves to prevent plate breakage or metal burrs from causing scratches.
2. Filling Handling: Low-quality recycled cotton may contain bacteria or chemical residues. After disassembly, seal it in packaging and label it as 'hazardous waste' to avoid secondary pollution.
3. Gas Cylinder Inspection: If the gas cylinder is of poor quality (e.g., lacks explosion-proof design), during disassembly, use a special tool to slowly release the gas to prevent sudden ejection and injury.

III. Core Structure Disassembly Steps for Swivel Office Chairs

1. Base and Gas Cylinder Separation: Invert the chair and use a wrench to loosen the base fixing screws, then slowly pull out the gas cylinder (use a rubber mallet to tap gently if stuck).
2. Chassis and Seat Cushion Separation: For single-lever control chassis, first remove the adjustment lever; for split chassis, disconnect the connecting screws between the seat cushion and backrest, and note the positions and quantities of the screws.
3. Mesh Backrest Handling: Check the weaving method (e.g., horizontal or vertical elasticity), use scissors to cut the fixing ropes, and retain the frame's elastic components for future maintenance reference.
4. Seat Cushion Filling Identification: High-density foam can be removed directly; for recycled cotton, check for mold or clumping, and handle separately if there is an odor.

Tip: If you need to replace the base of a lifting chair, it is recommended to refer to the official tutorial or contact after-sales service to avoid malfunction of the gas cylinder or chair tipping due to improper operation.
