Makeup Chair and Office Chair Installation

The installation steps for makeup chairs and office chairs are as follows:

Makeup Chair Installation Steps

1. Prepare Materials: Gather 4 steel legs, a complete seat cushion, 12 screws, and tools such as a wrench in advance.
2. Install Adjustable Feet: Screw the adjustable feet into the pre-drilled holes in the steel legs, ensuring a secure connection between the feet and legs.
3. Secure Legs to Seat: Align the holes in the steel legs with the corresponding holes on the bottom of the seat cushion, and temporarily fix the position with screws to prevent shifting.
4. Tighten Screws: Use a wrench to tighten all screws one by one, ensuring a firm connection between the steel legs and the seat cushion without any looseness.

Office Chair Installation Steps

1. Install Five-Star Base and Wheels: Insert the wheels into the pre-drilled holes in the five-star base. Some wheels may need to be rotated and tightened for a secure fit, ensuring a tight connection between the wheels and the base.
2. Install Gas Lift and Gas Lift Cap: Flip the five-star base over and insert the gas lift into the center hole. Remove the gas lift cap before insertion to avoid interference; the gas lift should be placed vertically to ensure stability during subsequent installation.
3. Install Seat Base: Place the seat cushion flat on a clean surface, align the seat base in the correct direction with the bottom of the cushion, and temporarily fix it with screws before tightening. Ensure the direction of the seat base matches the function of the cushion (e.g., the position of the adjustment mechanism).
4. Connect Seat to Gas Lift: Align the holes in the seat base with the top of the gas lift, and gently press down to fully insert the gas lift into the base, ensuring a wobble-free connection.
5. Install Armrests: Adjust the position of the armrests forward, backward, left, and right according to the direction of the seat cushion, and temporarily fix them with screws without fully tightening, leaving room for adjustment during the installation of the backrest.
6. Install Backrest: Align the backrest with the back of the seat cushion, first connect the holes at the bottom of the backrest with the armrests, and temporarily fix them with screws; then lift the backrest and install the top screws, keeping them loose at this stage.
7. Final Fixation: Adjust the backrest and armrests to the optimal position, then tighten all screws to ensure a stable structure; finally, install the armrest decorative caps to complete the overall assembly.

Precautions: During installation, check that all screws are tightened to avoid safety hazards caused by looseness; if the holes in the components do not match, stop installation and check for missing steps or incorrect parts.
