Various Office Chair Adjustments

The adjustment methods for different office chairs vary depending on the model and functional design, and corresponding operations should be selected based on the specific structure. Here is an operation guide for common adjustment functions:

1. Headrest Adjustment

• Leisure Dynamic Ergonomic Chair: The headrest supports height adjustment, which can be achieved by pulling up and down. However, the method for front-back adjustment is not clearly specified, and reference should be made to the product manual or customer service for confirmation.
• Quanpinwu Computer Chair: Featuring a 3D neck-protection design, the headrest can be adjusted by 6 centimeters in height and flipped by 60 degrees, accomplished through buttons or sliding structures at the back of the headrest.
• C500 Second Generation: The headrest adjustment function is integrated into the backrest system, usually allowing simultaneous adjustment of height and angle through knobs or catches at the back of the chair.

2. Backrest Adjustment

• Ergonomic Chair:
  • Angle Adjustment: Control the recline amplitude of the backrest through knobs or levers on the side of the seat. Some models support multi-level locking.
  • Height Adjustment: A adjustment lever is set at the back or side of the backrest. Pull it up, move the backrest up or down to the desired position, and release it to secure it automatically.
• C500 Second Generation: The backrest adjustment covers height, recline angle, and glide function (the seat cushion moves forward synchronously when reclining), operated through the control lever at the bottom or side buttons.
• Quanpinwu Computer Chair: The backrest supports a large recline angle of 172 degrees, paired with an adjustable footrest, suitable for lunch break scenarios. The adjustment button is usually located on the right side of the seat.

3. Lumbar Support Adjustment

• Quanpinwu Computer Chair: Equipped with a 4D airbag lumbar support, it supports up-down (within a 6-centimeter range) and front-back (within a 4-centimeter range) adjustments, operated through airbag buttons or sliding tracks on the side of the lumbar support.
• C500 Second Generation: Lumbar support adjustment may involve adjusting the elastic support force or fine-tuning the position, achieved through knobs or拨片 (a type of control) at the bottom of the backrest.

4. Seat Cushion and Height Adjustment

• General Method:
  • Locate the hand control device (such as a lever or knob) at the bottom of the seat, pull it up, and adjust the height by applying body weight pressure or repeatedly pushing. Reset the lever after adjustment.
  • When standing, adjust the chair so that the front end is just below the knees; when sitting, ensure both feet are flat on the ground and the thighs are parallel to the ground.
• C500 Second Generation: Supports seat height and depth adjustment. Seat depth adjustment is achieved through a sliding rail at the front of the seat, and seat height adjustment follows the general method.

5. Armrest and Footrest Adjustment

• C500 Second Generation:
  • Armrest adjustment may include height, angle, and front-back movement, operated through buttons or knobs on the side of the armrests.
  • Footrest adjustment requires unfolding the hidden footrest, and some models support fine-tuning of the footrest height or angle.
• Quanpinwu Computer Chair: The footrest is linked with the recline function. To unfold it, pull the unlocking device on the right side of the seat.

Adjustment Principles:

• Prioritize adjusting the headrest and lumbar support to fit the curves of the neck and lumbar spine;
• It is recommended that the recline angle of the backrest does not exceed 110 degrees to avoid affecting operational efficiency;
• Regularly check the stability of components such as the gas lift to ensure safe use.
  If there is any jamming or abnormal noise during operation, stop adjusting immediately and contact after-sales service for inspection and repair.
