How to Disassemble Office Chairs

The method for disassembling office chairs varies depending on the model and design. It is necessary to select the corresponding steps according to the specific structure and pay attention to the safety of tool use.

I. Disassembly Steps for the Beluck Office Chair BC03Q Premium Edition

1. Headrest Removal: Pull the headrest to its highest position, press down firmly on the thin metal strip in the middle, and pull it out once you feel the locking mechanism loosen. If the catch is tight, use a discarded hard card to assist in prying it open.
2. Armrest Removal: Invert the chair onto a high platform (such as a table), use the hex wrench that comes with the box to loosen the fixing screws beneath the armrests, and remove the armrests.
3. Separation of the Backrest and Base:
   • Use a hex wrench to remove the connecting screws between the backrest and the base.
   • The base consists of a gas spring and a five-star foot: Use a rubber mallet (or a regular hammer with a towel underneath) to tap each of the five feet of the five-star foot to separate them from the gas spring; then tap the base plate to detach the gas spring from the base.
4. Wheel Foot Removal: Simply pull off the wheel feet of the five-star foot with force. If the catches are tight, wiggle them left and right to assist in disassembly.

II. Disassembly Steps for Universal Ergonomic Chairs (No Professional Tools Required)

1. Headrest Removal:
   • For slip-on designs: Unscrew the fixing screws and remove the headrest.
   • For screw-fixed designs: Simply remove the screws to separate the headrest.
2. Armrest Removal: The screws are usually located on the back frame or seat cushion frame. Use a hex wrench or your hands to unscrew the fixing screws and remove the armrests.
3. Backrest Removal: Lay the chair down and remove the three fixing screws between the back frame and the chassis to separate the backrest.
4. Base and Gas Rod Removal: Use a hammer with a towel underneath to tap the connection points between the gas rod and the chassis, as well as the chair feet, until they loosen, then pull out the gas rod. If the gas rod is tightly connected to the five-star foot, wiggle it left and right to assist in separation.

III. Disassembly Steps for Other Lifting Chairs

Gas Rod Removal: Face the chair directly, step on the five-star foot to maintain stability,掰 (this word seems to be a typo, assuming it means 'pull') the lifting handle to its highest position and hold it; grasp both sides of the chair with your hands and pull upwards with force while wiggling left and right to assist in disassembling the gas rod.

Precautions

• Record Component Positions: It is recommended to take photos or record the connection methods of each component before disassembly to facilitate subsequent assembly.
• Tool Use Safety: When using screwdrivers and hammers, wear gloves to avoid cuts or bruises; use a towel underneath when tapping to prevent damage to the components.
• Keep Small Components: Adapters, screw packs, etc., should be stored properly to avoid loss and affect reassembly.
