To adjust the seat depth, use the same right-side lever. Push the lever forward to slide the seat forward or backward to accommodate your leg length, reducing pressure on your thighs and improving blood flow.

4. Lumbar Support (Self-Adaptive Lumbar Support 2.0)

The chair features a self-adaptive lumbar support system that automatically adjusts to your lower back's curve as you move. No manual adjustment is typically needed for this feature, as it dynamically cradles your spine.

The 3D Superwide Headrest can be adjusted for height and angle. To adjust the height, grasp the headrest and slide it up or down. To adjust the tilt, push it forward until it clicks into the desired position. To reset, push it all the way forward to release the mechanism, allowing it to return to its furthest back position.

6. Armrest Adjustment (8D Bionic Armrests)

The 8D Bionic Armrests offer multi-directional adjustments. They can be raised or lowered by lifting them to the desired height. To reset to the lowest position, lift them to their highest point and release. The armrests also swivel inwards and outwards, and can slide forward/backward to support various postures, including gaming, typing, or relaxing.
