Office Chair Quick Installation

For quick installation of an office chair, refer to the following steps. There may be slight differences depending on the model, so please refer to the product manual or installation video for specific instructions:

1. Install the chair wheels Insert each chair wheel into the assembly holes of the five-claw base one by one, ensuring that each wheel is fully seated in the hole to prevent looseness. Some chair wheels need to be pressed firmly to the bottom of the chair legs until a 'click' sound is heard, indicating proper installation. Check that the wheels rotate smoothly in this step to prevent sliding obstruction due to improper installation.

2. Install the gas lift Align the thicker end of the gas lift with the central hole of the five-claw base, place it vertically downward, and press lightly to ensure a tight connection between the gas lift and the base. For some models, place the gas lift directly into the reserved hole in the middle, paying attention to distinguish between the thick and thin ends of the gas lift to avoid reverse installation, which would result in the lifting function failing.

3. Install the base and seat cushion Place the base on the bottom of the seat cushion, paying attention to the orientation of the base (usually marked with 'front' and 'back'). After aligning the screw holes, use a screwdriver to screw each screw in 3-4 turns to initially fix the position, and then tighten all the screws one by one. For some models, first align the gas lift with the hole on the base, and then slide the base over the gas lift to ensure a secure connection.

4. Connect the backrest and seat cushion Align the bottom sides of the backrest with the armrest installation holes on both sides of the seat cushion. After inserting vertically, first use screws to fix the bottom of the backrest from the bottom of the armrest bracket, and then align the installation holes on the back of the backrest with those on the seat cushion bracket, and lock them with screws. For some models, first remove the seat cushion and backrest, fix the bottom of the backrest with three screws, and then tighten all the connecting screws to ensure that the backrest does not wobble.

5. Install the armrests Press the button below the armrest surface (some models have no button), and insert the left and right armrests into the holes of the armrest brackets respectively. A 'click' sound indicates proper installation. For some models, use screws to connect the armrests to the seat cushion, ensuring that the screws are tightened to prevent the armrests from loosening and affecting use.

6. Install the footrest (if applicable) Take the footrest and insert it into the reserved hole below the seat cushion, ensuring that the footrest is fully seated and can伸缩 freely (here '伸缩' means extend and retract, you may adjust the expression according to the actual context). Some footrests need to be fixed with screws, and tighten the screws according to the instructions to prevent them from falling off during use.

7. Install the headrest (if applicable) Place the headrest in the middle position at the top of the backrest, press the installation part of the headrest to make it fit more closely with the backrest, and use screws to pass through the headrest fixing buckles to lock the headrest with the backrest. For some models, insert the headrest directly into the reserved slot on the backrest, ensuring sufficient insertion depth to prevent the headrest from falling off.
