Office Chair Gas Lift Replacement

For replacing the gas lift of an office chair, first confirm that the gas lift is damaged, causing the chair to be unable to rise and fall normally, and then follow the steps of removal, selection, and installation for replacement. Details are as follows:

Removing the Old Gas Lift

• In the case of no screw fixation: Turn the chair over, step on the bottom with both feet, and try to remove the gas lift by shaking. You can also use a tool to tap the circular edge around the gas lift (be careful not to tap the bottom), and use the vibration to loosen the gas lift and then remove it.
• In the case of screw fixation: Use a vise-grip or similar tool to clamp the iron post, unscrew the upper part of the seat to separate the gas lift from the seat. Then, use a hammer or wrench to tap the bottom edge of the gas lift, or tap it after placing a wooden block underneath, and remove the gas post from the base by external force.

Selecting a New Gas Lift

• Determining the size: When measuring the size, pay attention to the sinking length. The thickness of the gas post interface is usually the same. Purchase according to the size of the original gas lift to ensure that the new gas lift can perfectly match the base and seat of the chair.
• Choosing the price: Purchase a suitable gas lift online. The price is generally around 8 - 30 yuan, and you can choose according to your budget and needs. When purchasing, choose a reputable merchant to ensure that you buy a qualified product.

Installing the New Gas Lift

• Installing it on the base: Align the new gas lift with the base of the chair, insert it slowly, and ensure that it is installed firmly. During the installation process, pay attention to the direction of the gas lift to ensure that it can work normally.
• Installing the seat: Put the stool on the installed gas lift, adjust the position, and then sit on it and press down to make the seat and the gas lift tightly combined. After installation, check whether the lifting function of the chair is normal to ensure that the replaced gas lift can be used normally.
