Office Chair Foot Disassembly and Assembly

The methods for disassembling and assembling the feet of office chairs vary depending on the specific components and design. Common operations include screw removal, snap-ring handling, and modular disassembly, and the appropriate method should be selected based on the actual situation.

Replacement of Footrests for Sihoo C300/C500

The footrests of the Sihoo C series (C300/C500) are secured with three screws. To replace them, use the matching screwdriver to remove these three screws, allowing you to take off the old footrest and install the new one. The chair comes with the screws needed for disassembly and assembly, so no additional preparation is required. However, it is important to ensure that the screw specifications match the tool to avoid stripping the screws or damaging the threads.

Replacement of Broken Office Chair Legs

If a chair leg needs to be replaced due to breakage, first deal with the iron ring that is stuck in the plastic: use a tool (such as a screwdriver) to gently tap the edge of the iron ring to loosen it and then remove the old leg. The new legs are mostly made of galvanized iron, which offers higher durability. When installing, ensure that the wheel snap-rings are correctly inserted into the leg holes to prevent loosening or detachment. Wear gloves during operation to prevent cuts from the metal edges.

Complete Disassembly of Office Chairs (Separation of Chair Legs from Gas Lift)

After long-term use, the gas lift and chair legs of an office chair may become tightly engaged due to friction, requiring a step-by-step disassembly process:

1. Separate the Backrest from the Seat: First, remove the fixing screws or snaps of the backrest to separate it from the seat.
2. Remove the Base: Raise the gas lift to its highest position, hold the seat with one hand, and press the lift adjustment lever with the other hand while shaking to loosen the base from the gas lift and then remove it.
3. Extract the Gas Lift: Invert the chair legs and gently tap the bottom of the gas lift with a rubber mallet (if a rubber mallet is not available, use a wooden board as a buffer) to avoid deforming the chair legs by direct tapping. Control the force during this step to prevent damage to the internal components of the gas lift.

Modular Design of Detachable Five-Star Feet

Some office chairs adopt a “detachable five-star feet” design (such as the KX-300-002 bread feet and KX-320-003 detachable feet from Anji Kaixin Furniture), which optimizes production and transportation through a modular structure:

• Structural Strength: The disassembly design must take into account strength, usually using high-strength plastic or metal materials to ensure stability after multiple disassemblies and assemblies.
• Ease of Installation: The components are fixed with snaps or screws, requiring no professional tools, allowing users to complete assembly or replacement on their own.
• Transportation Advantages: The modular design reduces space occupation, lowers logistics costs, and is suitable for bulk transportation.

Precautions: Read the product manual before disassembly to confirm the component structure; avoid violent disassembly during operation to prevent damage to other parts of the chair; if the snaps are too tight or the screws are rusted, apply lubricating oil to assist in the process.
