How to Install an Office Chair in Guyuan

The installation of an office chair in Guyuan can refer to the following two conventional processes, with specific steps adjusted according to the actual model:

Method 1: Step-by-Step Installation

1. Preparation Before Installation

   • Tool Organization: Prepare tools such as a cross-head screwdriver, adjustable wrench (or hex wrench), rubber mallet, and scissors.
   • Component Verification: Check that all components are present, including chair legs (five-star or four-leg), gas lift (height adjustment column), seat, backrest, armrests, headrest (for some models), screw pack, and instruction manual. If any components are missing or damaged, contact after-sales service immediately.

2. Step-by-Step Installation

   • Chair Legs and Gas Lift: Place the chair legs flat on the ground with the center hole facing up. Insert the gas lift vertically and press gently until fully seated, paying attention to the direction of the dust cover.
   • Securing the Seat: Align the bottom of the seat with the top of the gas lift and press down slowly until you hear a 'click' (indicating the latch is locked); for reclinable chair models, install the right-side recline control handle simultaneously.
   • Connecting the Backrest and Armrests:
     • Pre-assembled backrest: Adjust to an upright position;
     • Separate backrest: Secure with screws to the metal bracket at the rear of the seat.
     • Armrest Installation: Align with the screw holes on both sides of the seat, tighten with screws, ensuring symmetry.
   • Additional Components:
     • Headrest: Insert the rod into the预留 (pre-drilled) hole at the top of the backrest and rotate to the desired height;
     • Lumbar support: Attach to the middle of the backrest using Velcro or latches;
     • Casters: Press firmly into the holes at the ends of the chair legs until you hear a 'click'.

3. Post-Installation Inspection and Adjustment

   • Inspection: Shake the chair to test structural stability; check that height adjustment, recline, and rotation functions operate smoothly; ensure no screws are exposed and wheels are securely fixed.
   • Adjustment: Adjust the backrest recline tension (using the knob under the seat), headrest height (aligned with the earlobes), and armrest width (aligned with the natural drop of the elbows) according to personal preference. It is recommended to check screw tightness monthly to extend the chair's lifespan.

Method 2: Bottom-Up Installation

1. Casters and Chair Legs: Press each caster firmly into the holes at the ends of the chair legs, ensuring a 'click' confirms secure attachment; after installation, place the gas lift vertically into the center hole of the chair legs.
2. Base and Seat: Secure the base to the bottom of the seat with screws.
3. Connecting Backrest and Seat: Attach the backrest to the seat using hinges or screws, then insert the combined unit vertically onto the top of the gas lift.
4. Armrests and Headrest: Finally, install the armrests (aligning screw holes and tightening) and the headrest (inserting into the top hole of the backrest and adjusting height).

Precautions: Avoid excessive force during installation to prevent component damage. If latches fail to lock or screw holes are misaligned, recheck component models or contact after-sales service.
