Office Chair Spring Package

The office chair spring package is an accessory designed to enhance the comfort and durability of office chair cushions. Below are its installation methods, price ranges, and core functions:

Installation Methods
Taking the NB98 spring package for chairs as an example, installation should be carried out step by step:

1. Assemble the Five-Star Base and Gas Lift: Press the wheels firmly into the holes of the five-star base and align them correctly to ensure stability. Align the gas lift with the central hole of the decorative cover and insert it into the center of the five-star base to form the chair's bottom support structure.
2. Secure the Seat Cushion: Place the seat cushion with the holes facing upwards. Use connectors and 2-centimeter hex screws to fix the left and right sides of the cushion, ensuring a firm connection with the bottom structure.
3. Install the Footrest: If the chair is equipped with a footrest, first remove the rubber ring from the pipe opening, align the footrest with the connector, insert it, and then put the rubber ring back on to secure it, providing leg support.
4. Fix the Armrests and Reclining Support: Secure the left and right armrests to the sides of the seat cushion using 3-centimeter hex screws. Fix the reclining support to the center of the seat cushion with 2-centimeter hex screws to provide a support point for the backrest.
5. Connect the Backrest and Headrest: Align the backrest with the upper hole of the reclining support and insert the gas lift into the hole of the reclining support. Fix the headrest to the upper hole of the backrest with a 2.5-centimeter hex screw, and finally snap in the small decorative cover to complete the overall assembly.

• Health Support: Proper design can protect the lumbar spine and leg muscles, maintain correct sitting posture, and reduce health risks caused by improper posture.
• Improved Durability: The spring package buffers the force applied to the seat cushion, reduces material wear, and effectively extends the overall lifespan of the chair.
