Assembly Instructions for Office Chairs

The assembly steps for office chairs from different brands are as follows:

Deli Office Chair:

1. Install the Ball Bearings: Press the internal structure of the ball bearings into the designated position with slight force to secure them. Ensure the ball bearings are fully embedded to prevent loosening during subsequent use.
2. Install the Seat: Place the seat bottom-up first, align the screws with the pre-drilled holes and press them in, then install some screws according to the direction indicated by the arrows. After placing the backrest, install the remaining screws involved, and finally install the decorative cover to conceal the screw holes and enhance aesthetics.

TOAI E1 Office Chair:

1. Basic Structure Assembly: Press the five wheels into the corresponding holes on the chair base to ensure the clips are secure; insert the gas lift into the center hole of the chair base as the core component for height adjustment.
2. Backrest and Seat Cushion Connection: Fix the backrest and seat cushion with three M8 screws, tightening them until there is no wobbling to prevent loosening during long-term use.
3. Armrest Installation: Connect the armrests to both sides of the seat cushion, flip the chair seat over, and then secure the armrest on the other side to ensure symmetry.
4. Footrest and Base Assembly: Insert the footrest into the pre-drilled hole beneath the seat cushion, then align the gas lift with the base and insert it to complete the connection of the support structure.
5. Headrest Installation: Insert the headrest into the pre-cut slot at the top of the backrest, ensuring the clips are in place to provide neck support.

Ordinary Office Chair:

1. Wheel and Gas Lift Installation: Install the five wheels into the chair base, insert the gas lift into the center hole. The gas lift, as a key component for height adjustment, must be inserted vertically and securely.
2. Base and Seat Plate Connection: Align the base with the bottom of the seat plate, and secure the base with four long screws, ensuring the screws are tightened until there is no gap to prevent the seat plate from wobbling.
3. Backrest and Seat Connection: Install screws at the corner brackets connecting the backrest and seat, aligning the holes before tightening to ensure the angle between the backrest and seat cushion is fixed, providing stable support.

Precautions:

• Before assembly, check that all components are complete to avoid interruptions due to missing parts during the process.
• Tighten the screws in stages. For example, for the Deli office chair, install some screws first and then install the remaining ones to prevent misalignment of components.
• The gas lift must be inserted vertically to prevent adjustment failure or safety hazards caused by tilting.
• After assembly, check that all components are secure, especially load-bearing parts such as wheels and gas lifts.
