Leather Office Chair Installation

The installation of a leather office chair requires selecting the appropriate method based on the specific model and component type. Common installation steps are as follows:

I. Modular Installation of the Livorno M30 Leather Chair

This model features a modular design, simplifying the installation process to three steps:

1. Install the Five-Star Base and Gas Lift: Place the five-star base flat on the ground, ensuring the five legs are evenly spread. Insert the gas lift vertically into the center hole of the five-star base and press gently until fully embedded, ensuring a secure and wobble-free connection.
2. Install the Seat Cushion: Align the bottom connector of the seat cushion with the top of the gas lift and press down vertically until you hear a 'click', indicating the latch is locked. If the seat cushion is secured to the gas lift with screws, use an Allen wrench to tighten them clockwise.
3. Function Test: After installation, sit on the chair and adjust the height of the gas lift to check for smooth lifting and lowering; rotate the chair to test the flexibility of the five-star base, ensuring there is no jamming or unusual noise.

II. Universal Installation Process for Leather Office Chair Armrests

Armrest installation should follow these standardized steps:

1. Preparation: Invert the chair so that the backrest faces down and the five-star base faces up. Clear the work area of any debris. Prepare tools such as a Phillips screwdriver and an Allen wrench, and confirm the left and right directions of the armrests (usually marked with 'L' and 'R' labels).
2. Align Holes and Initial Fixation: Clean the screw holes at the connection between the armrests and the chair body. Align the armrests with the installation holes and secure them temporarily with screws. Note: The screws do not need to be fully tightened at this point; leave 2-3 millimeters of play for subsequent adjustments.
3. Tighten Screws Diagonally: Once both armrests are initially in place, gradually tighten the screws in a diagonal sequence (e.g., first the front left, then the back right) to ensure even force distribution and prevent the armrests from tilting.
4. Function Check: After installation, upright the chair and test the stability of the armrests: press firmly on the armrest surfaces to check for looseness; adjust the chair's backrest or lifting function to confirm that the armrests do not interfere or produce unusual noise.

III. Basic Principles for Universal Disassembly and Installation

Applicable to scenarios such as cushion or backrest replacement or repair:

1. Component Separation Methods:
   • Screw-Fixed Models: Use the corresponding screwdriver to unscrew the screws at the connection points counterclockwise. Be sure to save the screws and store them separately.
   • Latch-Fixed Models: Locate the plastic latches and use a flat tool (such as a bank card) to gently push or pull along the latch缝隙 (gap) to separate the components. Avoid using excessive force to prevent the latches from breaking.
2. Notes for Electric Adjustment Models: If the chair has electric functions (such as massage or heating), disconnect the power cord first to prevent the risk of short circuits or electric shocks; reconnect the power after installation is complete and test the functions for normal operation.

Tip: Before installation, be sure to read the product manual to confirm the component list and tool requirements; if you encounter complex structures (such as hidden screws or irregular latches), it is recommended to contact the manufacturer's after-sales service or watch installation videos for assistance.
