Assembly Instructions
Follow these steps carefully for proper assembly. It is recommended to assemble the chair on a soft, clean surface to prevent damage to the chair or your floor.
Video: This video demonstrates the step-by-step assembly process for the BestGlory BG-488 Executive Office Chair. It covers attaching the base plate to the seat cushion, inserting the gas lift, and connecting the backrest and armrests.
- Attach the base plate to the underside of the seat cushion using the provided screws and hex wrench. Ensure the 'FRONT' label on the base plate aligns with the front of the seat cushion.
- Insert the casters into the holes on the chair base until they click securely into place.
- Place the gas lift cylinder into the center hole of the chair base.
- Carefully place the assembled seat cushion onto the gas lift cylinder.
- Attach the armrests to both the seat cushion and the backrest using the remaining screws. Do not fully tighten all screws until all components are loosely attached to allow for alignment.
- Once all parts are aligned, securely tighten all screws.
Operating Your Chair
Your BestGlory Executive Office Chair is designed with multiple adjustable features for personalized comfort.
Height Adjustment
To adjust the seat height, locate the lever under the seat on the right side. Pull the lever up to raise the seat. To lower, remain seated and pull the lever up. Release the lever at the desired height.

Rocking Function and Tilt Lock
The chair features a rocking mode and tilt lock. To activate the rocking function, pull the lever (often the same one used for height adjustment, or a separate knob) outwards. To lock the tilt at a desired angle (between 90° and 135°), push the lever inwards. Adjust the tilt tension by rotating the round knob located under the front of the seat; turn clockwise to loosen for easier rocking, counter-clockwise to tighten for firmer resistance.

Adjustable Flip-Up Armrests
The armrests can be flipped up to save space or allow the chair to be pushed closer to a desk. Simply lift the armrests upwards until they lock into a vertical position. To return them, pull them down.

Lumbar Support and Headrest
The ergonomic design includes an S-curve lumbar support and a double-padded headrest for enhanced comfort and fatigue relief. These are fixed features designed to support natural spinal alignment during long periods of sitting.

- Casters: Keep the casters free of hair, dust, and other debris to ensure smooth movement across various floor surfaces.
