Office Chair Posture

Office chair posture requires comprehensive adjustments in terms of seat height, sitting angle, arm support, monitor height, etc., while avoiding poor postures and choosing the correct sitting posture type according to needs.

1. Seat Height
Adjust the seat height so that your feet are completely flat on the ground, with your thighs and lower legs forming an angle of 95°-100° to ensure an even distribution of body weight. If the chair is too high and your feet are dangling, use a footrest; if the chair is too low, it will increase the pressure on your knee joints, which may lead to joint pain over the long term.

2. Sitting Angle
Maintain a slightly reclined posture, with the backrest and torso forming an angle of 100°-110°, which can effectively reduce lumbar pressure. The key is that the back (especially the lower back) should fit against the backrest. If the chair is equipped with a lumbar support, adjust it to the position that supports the natural curve of the lumbar spine to avoid a hollow lower back.

3. Arm Support
The height of the armrests should be consistent with the height of your elbows when they are hanging naturally, allowing your forearms to rest easily on the armrests or the desktop, with your upper arms and forearms forming an angle close to 100°. This posture can disperse shoulder pressure and prevent shoulder and neck stiffness or pain.

4. Monitor Height
Raise the monitor or use a stand so that your line of sight is level with the top edge of the screen. This setting forces the spine to stretch naturally and avoids increasing neck pressure due to forward head posture (studies show that a forward head posture can increase neck pressure by 3-5 times).

5. Avoid Poor Postures
Be alert to actions such as slouching, shrugging, or forward head posture. Slouching increases the burden on the lumbar spine, shrugging can easily cause tension in the shoulder and neck muscles, and forward head posture directly compresses the cervical spine, which may lead to cervical spondylosis or scoliosis over the long term.

6. Correct Sitting Posture Types

• Upright Sitting: Pair with an ergonomic chair, a height-adjustable desk, and a monitor stand to ensure that the neck, back, and lower back are all supported, suitable for long periods of focused work.
• Reclined Sitting: Requires a leg rest, a height-adjustable desk, and a monitor stand. By adopting a semi-reclined posture, it disperses body pressure and is suitable for short breaks or reading.
• Standing: Reduce the risks of prolonged sitting by alternating between standing and sitting. It requires a height-adjustable desktop to maintain a neutral spine position.
• Riding Sitting: Between sitting and standing, it maintains an upright spine through a posture similar to horse riding and requires a height-adjustable desk. It is suitable for scenarios that require flexible movement.

It is recommended to choose a suitable sitting posture according to work needs and alternate and adjust every 30-60 minutes to reduce the continuous pressure on the body from a single posture.
