Office Chair Leather Pad Removal

The removal of the leather pad from an office chair should be carried out step by step, using specialized tools and paying attention to safety precautions. The specific process is as follows:

1. Prepare Tools
   Have a rubber mallet (avoid using a metal hammer to prevent damage to the paint surface), a Phillips or flat-head screwdriver, a wrench, and large scissors or diagonal pliers ready in advance. The rubber mallet is a crucial tool; its elasticity reduces the impact on the chair's structure when striking. The screwdriver and wrench are used to remove fixed screws, while the large scissors or diagonal pliers are for clearing tangled debris.

2. Remove Casters
   Casters are usually fixed to the chair legs with clips. Simply grasp the wheel with your hand and pull it outward. If it is stuck due to long-term use, insert a flat-head screwdriver or diagonal pliers into the gap between the wheel and the chair leg and gently pry to separate the clip. If the wheel is jammed by tangled hair or fibers, first invert the chair and use long scissors or curved-tip tweezers to clear the debris, then repeat the above operation. Note: Avoid scratching the surface of the chair legs during cleaning.

3. Remove the Gas Lift
   Fully invert the chair to expose the connection between the gas lift and the five-star base (chair legs). Strike the lower part of the connection between the gas lift and the five-star base (usually a red or silver metal part) with a rubber mallet, avoiding the green or black areas with hydraulic oil. If the connection is too tight, apply a small amount of cooking oil to the joint for lubrication and let it sit for 1-2 hours before striking again. It is strictly prohibited to use a metal hammer or wrench to pry hard, as this may damage the seal of the gas lift, leading to air leakage or the risk of explosion.

4. Remove the Seat Cushion
   After removing the gas lift, invert the chair on the ground. Strike evenly around the metal rim at the bottom of the seat cushion with a rubber mallet to separate the base from the cushion. Then, use your hand to pull the cushion upward and repeat the operation until the base loosens. Next, use a screwdriver to remove the upper screws connecting the seat cushion and the chassis, and continue to strike the metal chassis lightly with the rubber mallet. During operation, hold the hydraulic rod with one hand and step on the chassis with one foot, applying slow force to completely separate the two. Control the force in this step to avoid damaging the hydraulic rod or the internal structure of the seat cushion.

Operation Tips: It is recommended to take photos of the chair's structure before disassembly for easier reassembly later. If you encounter stubborn screws, spray a small amount of penetrating oil to assist in removal. Wear gloves throughout the process to prevent cuts or contact with hydraulic oil on the skin.
