Assembly of Black and White Office Chair

The assembly steps for black and white office chairs vary depending on the model. It is necessary to select the corresponding process according to the specific model. Here are the assembly methods and general suggestions for some common models:

I. Assembly Steps for Model P1 (P101BXA)

1. Installation of Chair Legs and Pneumatic Rod: Invert the five-claw chair legs, insert the five chair wheels in sequence, and then flip them over so that the wheels touch the ground; vertically insert the thick end of the pneumatic rod into the center hole of the five-claw base.
2. Fixing the Armrests: Use six A screws (three on each side) along with washers to fix the armrests on both sides. The screws should be tightened in stages (first tighten to one-third, and then fully tighten).
3. Connecting the Seat Cushion and Pneumatic Rod: Align the top of the pneumatic rod with the hole on the seat cushion base, insert it vertically, and ensure it is secure.
4. Installing the Chair Back Steel Plate: Align the chair back steel plate with the four holes on the base, and fix it with four B screws; users under 175cm in height need to adjust the hole positions according to the video.
5. Assembling the Neck Pillow and Chair Back: Insert the neck pillow connector into the protrusion on the chair back, and fix the neck pillow with two C screws; then align the holes on the back of the chair with the holes on the steel plate, and tighten them with four B screws.
6. Fixing the Chair Back Shell: Insert the shell into the slot on the chair back, and fix it from the bottom with two D screws.

II. Assembly Steps for Model E301

1. Installation of Chair Legs and Pneumatic Rod: Pull out the decorative cover of the central axis of the five-claw base, insert it into the chair legs, and fix it with five F screws, then install the chair wheels; flip the five-claw base, cover it with the decorative cover, and insert the pneumatic rod.
2. Assembling the Footrest: Connect the footrest surface and the sliding rod with two G screws, fix the slider to the bottom of the seat cushion (four H screws), insert the footrest, and screw back the pre-installed screws.
3. Fixing the Base: Fix the base to the bottom of the seat cushion with four D screws.
4. Connecting the Armrests and Backrest: Insert the armrest brackets into the holes on the backrest (four B screws), then insert the armrests and fix them with two C screws.
5. Installing the Backrest and Pneumatic Rod: Fix the backrest to the base with three C screws, insert the pneumatic rod, and align it with the holes on the base.
6. Installing the Headrest: Align the protrusion on the headrest with the groove on the backrest and insert it, and fix it with two E screws.

III. General Assembly Suggestions

1. Preparation: Before assembly, check the list of accessories (such as screw packs, tools, etc.) to ensure nothing is missing; for some models (such as E3 Pro), due to the heavy hardware, it is recommended that two people collaborate on the installation.
2. Screw Fixing Principle: All screws should be tightened in stages to avoid misalignment of components due to unilateral force; if resistance is encountered, check whether the holes are aligned.
3. Safety Tips: When installing the pneumatic rod, keep it vertical to avoid air leakage caused by tilting; if any accessories are found to be damaged during assembly, contact after-sales service immediately for replacement.
