How to Adjust the Reclining Angle of an Office Chair

There are several ways to adjust the reclining angle of an office chair, and the specific operation should be selected according to the type of chair:

1. Mechanical Knob Adjustment
Take the Steelcase Gesture as an example. First, adjust your sitting posture: push the seat cushion forward until your legs are naturally bent at a 90-degree angle (with the angle between your knees and hips approximately 110 degrees) to ensure a stable center of gravity. Then, use the metal knob on the left side of the backrest for adjustment. Rotating it clockwise 1-3 times allows for stepless adjustment from 15° to 135°. The green marking line on the knob's dial indicates the 135° optimal reclining angle recommended by ergonomics, suitable for short breaks or relaxing the spine. Adjust slowly to avoid body imbalance due to sudden angle changes.

2. Pneumatic Rod Linkage Adjustment
Similar to the pneumatic rod system of the Herman Miller Aeron, the operation should be done in steps: First, press and hold the red button on the lower right side of the seat cushion for 3 seconds and slowly straighten your back to an upright position. After releasing the button, hold the handles on both sides of the pneumatic rod with your hands. At this time, the built-in sensor in the seat (with an accuracy of ±2kg) will automatically calculate your height and weight data and complete the self-adaptive reclining angle adjustment within 8-12 seconds. This method is suitable for users who need precise matching of their body curves, but it is necessary to maintain body stability to avoid shaking during the adjustment process.

3. Smart Touch Adjustment
The Eu-Bio Gold series is equipped with an APP adjustment system that requires Bluetooth connection to the device. Users need to complete a three-step authentication process: take a photo and upload the QR code on the seat for anti-counterfeiting verification, fill in height and weight data (with an error of less than 5cm), and select a work mode (meeting/creation/rest). The system will generate a three-dimensional adjustment plan based on the data, including recommended reclining angle values, recommended seat depth values, and lumbar support height (accurate to the millimeter). This method is suitable for users who pursue personalized adjustments, but it relies on electronic devices and takes some time for initial setup.

4. Button Adjustment
Some office chairs adopt a simple button design: pushing the button inward puts it in the locked state, where only the seat height can be adjusted up and down, and the reclining angle cannot be adjusted. Pulling the button outward unlocks it, allowing users to adjust the seat to their preferred reclining angle. After adjustment, push the button inward again to lock it. Pay attention to the force when adjusting to avoid button damage or sudden angle changes due to excessive force.

5. Regulator Adjustment
The regulator can be found under the chair. When operating, pull the regulator upward while continuously applying force to the backrest to make the chair back tilt. Before reaching the appropriate angle, maintain hand force and body stability. After reaching the desired tilt, release the regulator to fix it. This method is suitable for users who need manual fine-tuning, but it requires a certain amount of arm strength support.
