Black and White Office Chair Installation

The installation steps for different models of black and white office chairs are as follows:

Black and White P1 (P101BXA)

1. Installation of Chair Legs and Wheels: Invert the five-claw base, insert the five chair wheels into the assembly holes of the chair legs one by one, and then flip it over so that the wheels touch the ground; insert the thick end of the gas lift into the center hole of the five-claw base.
2. Armrest Installation: Take one armrest, pass three A screws (with washers) through the holes, screw them in one-third of the way first, and then tighten them with a wrench; repeat the same process for the other side.
3. Connection of Seat Cushion and Gas Lift: Fix the assembled seat cushion onto the gas lift.
4. Installation of Chair Back Steel Plate: Depending on height (those under 175cm need to adjust the alignment method), fix the chair back steel plate to the base with four B screws, screwing them in one-third of the way first and then tightening them.
5. Neck Pillow Installation: Insert the neck pillow connector into the protrusion at the bottom of the chair back and secure it with two C screws; then insert the chair back shell into the slot and secure it with two D screws.
6. Overall Fixation of Chair Back: Align the holes at the back of the chair back with the holes on the steel plate and fix them with four B screws.

Black and White E301

1. Installation of Chair Legs and Wheels: Pull out the decorative cover of the central axis of the chair legs, insert the chair legs, and secure them with five F screws; insert the chair wheels into the assembly holes, flip the five-claw base, cover it with the decorative cover, and insert the gas lift.
2. Footrest Installation: Connect the footrest surface to the slide bar (with two G screws), and fix the footrest slider to the bottom of the seat cushion (with four H screws); insert the footrest and screw back the pre-installed screws.
3. Installation of Base and Armrests: Fix the base to the bottom of the seat cushion with four D screws; insert the armrest brackets into the holes on both sides of the backrest (secure them with four B screws), then insert the armrests and secure them with two C screws.
4. Installation of Backrest and Headrest: Secure the backrest to the base with three C screws; align the chair with the gas lift and insert it into the base hole; snap in the headrest, adjust its position, and secure it with two E screws.

Black and White P5 Dual-Back Model (P303 BMA)

1. Installation of Chair Legs and Wheels: Remove the decorative cover from the center of the five-claw base, insert the chair legs, and secure them with five A screws; insert the wheels, flip the five-claw base, cover it with the decorative cover, and insert the gas lift.
2. Installation of Armrests and Base: Align the armrests with the pre-embedded nut holes on the seat cushion, and preliminarily fix them with three B screws (do not tighten them yet); align the base with the holes on the seat cushion, position it with four C screws, and then tighten them.
3. Chair Assembly and Lumbar Support Adjustment: Insert the chair part into the gas lift; adjust the height of the lumbar support and lock the backrest with the knob.
4. Installation of Backrest and Headrest: Connect the backrest to the armrest brackets (preliminarily fix them with four D screws and then tighten them); lay the chair down and tighten the six screws on the armrests; align the holes on the headrest with those on the backrest and secure them with two D screws.

Precautions: Before installation, check the list of accessories to ensure that the screw models and quantities match; avoid applying excessive force when using tools to prevent screw slippage; some steps require two people to collaborate (such as fixing the base or backrest).
