Correct sitting posture when working with a computer prevents back pain, neck strain, and other health issues. Properly adjusting an ergonomic chair will provide comfort, help you maintain the correct posture for extended periods, and enhance work performance. In the following article, let’s explore 4 correct sitting postures and 5 popular support accessories office workers favor.
1. Discover 4 Correct Sitting Postures When Using a Computer
To reduce stress on the body, you should frequently change your posture, alternating between sitting, standing, resting, and using supportive devices like ergonomic chairs or height-adjustable desks. Each posture should be maintained for about 30 minutes before switching to avoid pressure on the spine and muscles while improving blood circulation and reducing fatigue. Below are 4 recommended sitting postures you should adopt when working with a computer, whether at home or in the office:
Basic Working Posture: Users should sit up straight, keeping the head and neck in a natural position so the eyes are level with the screen. The feet should be flat on the floor, knees at a 90-degree angle, and elbows parallel to the desk to reduce muscle strain and prevent fatigue.
Low Leaning Back Posture: To relieve pressure on the spine, users can recline the chair at an angle of 100 to 110 degrees. Feet should still touch the floor, with thighs parallel to the ground. This posture is suitable for light relaxation while maintaining focus on work.
Leaning Forward Posture: Users should lean slightly forward for heightened concentration, ensuring the buttocks have full contact with the seat. The feet must be firmly placed on the floor or a footrest for balance. This posture is particularly beneficial for tasks that require precision and meticulousness.
Half-Standing, Half-Sitting Posture: Users need to adjust the chair higher to alternate between sitting and standing, reducing strain on the back and legs. This posture helps improve blood circulation and maintain energy for longer, making it suitable for prolonged work throughout the day.

2. Other Factors to Consider for Maintaining Correct Computer Sitting Posture
In addition to maintaining the four correct sitting postures, you should also consider the following four important factors to maintain proper computer sitting posture.
2.1. Height and Position of the Monitor
Position the monitor at eye level so that your gaze hits the top third of the screen when looking straight ahead. According to experts, the ideal distance from your eyes to the screen is 50 to 70 cm to reduce eye strain. Additionally, if you're using a laptop, consider using a stand to raise the screen to the proper eye level, ensuring that your neck and back can maintain a natural, comfortable position.
Placing the monitor at the correct height and distance helps reduce pressure on the neck and shoulders, preventing chronic pain. You can maintain better focus and ensure consistent work performance when you’re not straining your neck or bending over for long periods.
2.2. Position of the Keyboard and Mouse
You should place the keyboard level with your elbows so that your arms form a 90-degree angle, keeping your hands comfortable and reducing muscle strain. Additionally, maintain a distance of 4 to 6 inches (10 to 15 cm) between the edge of the desk and the keyboard to provide wrist support, and position the mouse close to the keyboard for easy reach, avoiding strain from extending your arm too far. Using a keyboard with a wrist rest can also enhance comfort and reduce tension during extended work sessions.
Correctly arranging your keyboard and mouse helps you maintain a comfortable posture, limits muscle strain shoulder fatigue, and reduces the risk of developing carpal tunnel syndrome. When your hands and shoulders are relaxed, you can work more effectively, enhance your focus, and reduce the exhaustion caused by ongoing discomfort.
2.3. Eye Movements
You should follow the 20-20-20 rule: after 20 minutes of work, look away at something at least 20 feet (about 6 meters) away for 20 seconds to relax your eyes. Additionally, blink frequently to keep your eyes moist and avoid dryness. If you spend long periods in front of a screen, consider using a blue light filter to reduce the effects of screen glare, which can help protect your vision.
Taking care of your eyes and allowing them to rest properly can help reduce eye strain, dryness, and the risk of vision deterioration. When your eyes are relaxed, you’ll feel less tension and fatigue, which is especially beneficial for those working long hours in front of a screen.
2.4. Breathing Habits
Deep and steady breathing is an important habit that helps relax the body and improve concentration while sitting at a computer. After every 30 to 60 minutes of work, you should take a break, stand up, and perform a few stretching exercises combined with deep breathing.
Proper breathing ensures that your brain receives enough oxygen, enhancing your ability to think and concentrate. By regularly practicing good breathing habits, you can reduce stress levels and lower the risk of health issues related to headaches, fatigue, and sleep disturbances.
3. Why is Correct Sitting Posture Important?
Maintaining the correct sitting posture while using a computer not only improves health but also increases comfort, enhances focus, and helps sustain long-term productivity. Here are six key benefits of sitting correctly at the computer:
3.1. Reduces Back Pain and Protects the Spine
Maintaining correct sitting posture helps alleviate pressure on the spine, especially in the lower back, by preventing habits like slouching or leaning improperly. When pressure is evenly distributed, you reduce the risk of lower back and shoulder pain.
Conversely, if you maintain poor posture for an extended period, you may encounter serious issues such as spinal degeneration, herniated discs, or spinal curvature. These conditions cause pain, disrupt daily activities, and diminish work performance, making it more difficult to maintain health and quality of life.
3.2. Reduces Neck and Shoulder Tension
Sitting correctly and positioning the monitor at the appropriate height helps prevent the need to lean down or tilt your neck excessively, thereby reducing pressure on the neck and shoulders. Properly arranging the keyboard and mouse also minimizes the risk of placing your hands incorrectly, which can strain muscles and joints.
With the right posture, you decrease the risk of shoulder pain and muscle stiffness and prevent serious issues like cervical spine degeneration. Your body remains more relaxed, allowing you to maintain productivity for longer without feeling fatigued.
3.3. Prevents Carpal Tunnel Syndrome
Correct sitting posture helps alleviate pressure on the median nerve, preventing carpal tunnel syndrome and providing comfort during prolonged work sessions. When the chair is adjusted to the right height, your arms rest naturally, keeping your wrists straight and free from unnecessary pressure. This way, you don’t have to exert excessive force when using the keyboard and mouse, reducing nerve compression.
Proper posture lowers the risk of injury and prevents symptoms such as numbness, pain, or swelling in the wrists. Conversely, maintaining poor posture over time can lead to loss of sensation or impaired hand function, negatively affecting work and daily activities.
3.4. Reduces Eye Strain and Improves Vision
Sitting correctly helps maintain an ideal distance of 50 to 70 cm between your eyes and the screen, reducing strain on the eyes and minimizing excessive accommodation. This can help you avoid discomfort such as dry eyes, blurred vision, headaches, or the risk of developing computer vision syndrome. Ensuring the proper distance and posture protects your eyesight and enhances your ability to concentrate, thereby improving work efficiency over long periods.
3.5. Improves Blood Circulation
Correct sitting posture, especially when keeping your back straight and feet comfortably on the floor, enhances blood circulation through your back and legs. This prevents leg numbness and swelling, reducing the risk of venous thrombosis. Good circulation also helps maintain energy levels for longer, reduces feelings of fatigue, and enables you to work effectively and comfortably throughout the day.
3.6. Enhances Work Mood
Sitting correctly makes your body more comfortable, reducing fatigue and stress, which contributes to an improved mood while working. You can maintain focus and stay motivated when you aren’t constantly adjusting your posture to alleviate pain. A positive and relaxed mental state increases concentration and stimulates creativity, helping you complete tasks efficiently and enjoyably throughout your work process.
