Method 1:
Initial Removal Steps:
1. Detaching the Backrest and Tilt Mechanism from the Gas Lift:
- Refer to the attached video.
- Grasp both sides of the backrest/seat with your hands.
- Press down on the wheelbase using your left foot.
- Pull up to separate the backrest from the tilt mechanism. Note: There's no need to remove screws or any other parts for this step. Due to the chair's usage, the mechanism and gas lift might fit snugly. It might require a few attempts.
2. Wheels Removal: Detach all the wheels from the base.
3. Gas Lift Removal from Base:
- Place the base flat on the ground.
- Stand on the middle of the base as shown in the attached video.

Method 2:
If the above steps don't yield results, you can try the methods detailed in the provided video and picture:
Gas Lift Removal from Tilt Mechanism:
- Turn the cushion upside down.
- Use a cloth-wrapped hammer to gently tap the gas lift.
- To separate the gas lift from the tilt mechanism, use pliers.
- Important Notice: During the accessory replacement process, please be aware that our product accessories are made of iron and are relatively heavy. To avoid any damage, do not operate on vulnerable or expensive surfaces, such as floors or tiles. Instead, perform the replacement on a sturdy, protected surface.
- During the replacement process, standing on the wheelbase and shaking the chair can make it unstable. It is recommended to have someone support you or hold onto a fixed table to prevent falling.
Method 3:
If you still can't disassemble it using the above method，you can also try the following method：
First and foremost WD-40 or any grease is essential to this task to loosen up the connection of the bottle with the seat especially after long use since it might get a bit rusty
Proper pipe wrench is very helpful because of the amount of physical force this task require.
- Use your WD-40 or grease where the bottle is connected with your seat and turn it upside down so it has an easier time to penetrate and leave it for a couple hours (at least 1).
- Then, tap the tray and the gas cylinder with a hammer. Once it loosens, try Method 1 or 2 again.
Important Considerations
- Protect the surfaces: Use a cloth or protective material to prevent damage to the chair's components.
- Check for wear and tear: Inspect the gas lift and base for any signs of damage or excessive wear before attempting to separate them.
- Consult the manufacturer's instructions: Always refer to your chair's specific manual for the correct disassembly procedure, as mechanisms may vary between different models.
