Aurora Office Chair Adjustment

The adjustment methods for Aurora office chairs mainly include the regulation of functions such as height adjustment, seat cushion, lumbar support, armrests, and headrests, as detailed below:

Height Adjustment:
The height adjustment function of Aurora office chairs is usually achieved through the pneumatic height adjustment lever located beneath the seat. Taking the MH office chair as an example, pull the lever all the way out and then push the second lever upwards to raise the seat. For most models, the height adjustment lever is located on the right-hand side beneath the seat, equipped with an operating handle or button. Simply lift or press down gently to adjust the height. When adjusting, maintain a seated position and feel the change in seat height. The appropriate height is achieved when the knees are slightly more than 90 degrees bent and the feet can naturally rest flat on the ground.

Seat Cushion Adjustment:

• Overall Height: Adjust the overall height of the seat to ensure that when seated, the feet are completely flat on the ground, the thighs are roughly parallel to the ground, and the knees are bent at approximately 90 degrees.
• Seat Depth: Sit as far back as possible on the innermost part of the seat cushion and check the distance between the back of the knees (popliteal fossa) and the front edge of the seat cushion. The ideal state is to be able to easily fit 2 to 3 fingers (about 3-5 cm) to avoid compressing the leg nerves.
• Tilt Angle: Some mid-to-high-end models of seat cushions support forward or backward tilt adjustment. If the front edge of the seat cushion feels too high, use the adjustment handle (usually located on the right-hand side or left side beneath the seat cushion) to lower the front edge by about 3-5 degrees to distribute the pressure on the buttocks.

Lumbar Support Adjustment:
The lumbar support should be aligned with the natural curve of the lumbar spine (around the belt level, i.e., the L3-L4 region) to provide firm support. For example, the lumbar support of the CELY0103B adopts an adaptive elastic structure that dynamically conforms to the curve of the waist according to the sitting posture, reducing fatigue from prolonged sitting. When adjusting, move the lumbar support forward or backward or change its angle to ensure that the waist is closely fitted to the backrest.

Armrest Adjustment:
Some models of armrests support multi-directional adjustment. For example, the armrests of the CELY0302B can be adjusted vertically by 7 cm, horizontally by 5 cm, and rotated by 30 degrees to accommodate different arm lengths and operational needs. When adjusting, flexibly adjust the height and angle of the armrests according to the usage scenario (such as typing or reading) to keep the arms naturally hanging down and avoid shoulder and neck pain.

Headrest Adjustment:
Some models of headrests support multi-dimensional adjustment. For example, the 3D headrest of the CELY0103B can be adjusted vertically by 10 cm and rotated by 45 degrees, while the headrest of the CELY0302B can rotate 360 degrees, covering the height needs from 150 cm to 190 cm. When adjusting, align the headrest with the back of the neck to ensure that the head can be supported when leaning back, reducing pressure on the cervical spine.
