Disassembly of Large Office Chairs

The disassembly of large office chairs should be carried out according to the specific type. Taking an ergonomic chair (such as Okamura Sylphy) as an example, the following steps can be followed:

I. Preparation Before Disassembly

1. Confirm the Chair Type: Different types of office chairs (such as lift chairs and swivel chairs) have significant structural differences. First, identify the chair model. For ergonomic chairs, refer to the general disassembly logic; for other types, it is recommended to consult the tutorial based on the specific model.
2. Prepare Tools: Usually, no special tools are required, but some chairs may need a screwdriver (for base fixing screws) or a rubber mallet (to assist in separating components).
3. Clear the Space: Move the chair to an open area to avoid colliding with surrounding objects during disassembly.

II. Disassembly Steps for Ergonomic Chairs (Okamura Sylphy)

1. Lay the Chair Down: Tilt the chair backward or lay it down horizontally to facilitate operations on the bottom structure.
2. Adjust the Seat Depth: Slide the seat cushion to the maximum depth position to expose the bottom buckle structure.
3. Locate the Buckles: Observe the connection between the seat cushion and the chair frame, and find the buckles indicated by arrows on both sides (usually made of plastic and protruding).
4. Disassemble the Seat Cushion:
   • Press the Buckles Simultaneously: Use both thumbs to press the buckles on both sides at the same time, maintaining even pressure.
   • Slide to Separate: While pressing the buckles, slide the seat cushion forward (in the opposite direction of installation) until it is completely detached from the chair frame.
   • Pay Attention to the Force: If the buckles are tight, gently shake the seat cushion to assist in separation, avoiding excessive force that may damage the buckles.

III. Disassembly of Other Components (General Suggestions)

1. Base Disassembly: If the base needs to be replaced, first flip the chair over, unscrew the bottom fixing screws (if any) with a screwdriver, and then gently tap the edge of the base to separate it from the gas cylinder.
2. Gas Cylinder Disassembly: For some chairs, the gas cylinder and the base are designed as one piece and require a special tool (such as a gas cylinder disassembly tool) to separate them; if they are separate, they can be directly rotated and pulled out.
3. Armrest Disassembly: The armrests are usually fixed to the chair frame with screws. Unscrew the screws with a screwdriver to remove them.

IV. Precautions

1. Safety First: Avoid being scratched by sharp components during disassembly. If the chair is heavy, it is recommended to work with two people.
2. Record the Steps: Take photos to record the positions of various components before disassembly for easy subsequent assembly.
3. Keep the Parts: Store small parts such as screws and buckles separately to prevent loss.

If the chair type does not match the example, it is recommended to consult the official manual or contact after-sales service for accurate guidance first.
