Currently, the health of office workers is receiving increasing attention due to the nature of their work, which requires them to sit for many consecutive hours. Therefore, sitting in the wrong posture from the beginning not only negatively impacts health but also significantly reduces individual work productivity.
So, what are the recommended proper sitting positions for office chairs? Let’s explore 3+ correct ways to sit in an office chair to enhance focus and work efficiency in the article below.
1. Discover the Correct Sitting Posture According to Expert Advice
Sitting correctly while working in an office not only helps minimize issues like back pain and neck stiffness but also significantly improves work effectiveness. Below are four recommended sitting methods from health experts.
1.1. Method 1: Basic Sitting Position
To adjust your body to the basic working posture, follow these three main steps:
Step 1: Sit up straight with your back supported, ensuring both feet are firmly on the floor, creating a 90-degree angle between your thighs and lower legs.
Step 2: Use the lever to adjust the chair height so that your elbows form a 90-degree angle and are level with the desk when your arms are resting on it.
Step 3: Utilize the lever or smart adjustment button on the swivel chair to align the lumbar support with the natural S-curve of your spine, providing optimal support for your lower back. Additionally, ensure there’s a comfortable gap between your knees and the edge of the desk to avoid feeling cramped and to enhance comfort throughout your work session.
The basic sitting position helps support the spine and reduce pressure on the lower back and neck while minimizing musculoskeletal tension for office workers. Keeping your feet flat on the floor also improves blood circulation, reducing feelings of fatigue during an 8-hour workday.
1.2. Method 2: Sitting Low and Leaning Back
To achieve the correct sitting posture, adjust your chair so that the backrest tilts backward while still providing adequate support for the lower back and spine.
Step 1: Lean back into the chair and adjust the tilt angle so that your lower back is fully supported and the backrest follows the natural curve of your spine.
Step 2: Ensure both feet are firmly on the floor, with your knees forming a 90-degree angle to maintain a comfortable position without putting pressure on your legs and hips.
The leaning back sitting position helps relax back muscles and reduces muscle tension after long working hours. This posture distributes pressure evenly across the seat and backrest rather than concentrating it on the lower body, helping to alleviate swelling in the legs during prolonged sitting and providing a more comfortable experience.
1.3. Method 3: Leaning Forward
To properly execute this posture, adjust your chair so that your back and neck are adequately supported while your body leans slightly forward for comfort while working, following these three steps:
Step 1: Lean forward, adjusting the chair so that your back is still supported and your knees maintain a 90-degree angle with the floor.
Step 2: Ensure that the backrest and headrest are adjusted to provide optimal support for your back and neck while working.
Step 3: Your arms should rest comfortably on the desk, with your elbows forming a 90-degree angle to reduce pressure on your shoulders.
Note: Aim to keep your neck straight, avoiding excessive bending or leaning forward to reduce strain on the musculoskeletal system and maintain proper posture.
The forward-leaning position helps evenly distribute weight across the legs and hips while keeping the back well-supported by the chair. This reduces strain on the neck and back, providing comfort during long working hours, especially when using a computer. Maintaining the natural S-curve of the spine also helps prevent posture issues like hunching or spinal curvature.

1.4. Method 4: Half Standing, Half Sitting
The half-standing, half-sitting position is a flexible solution for those who want to change their posture frequently throughout the workday. You can use a standing chair to create a seamless transition between working and resting with these three steps:
Step 1: Use the standing chair, sitting at the edge so that the angle between your thighs and lower legs is approximately 10 degrees.
Step 2: Ensure the chair is at an appropriate height so that your feet can rest firmly on the floor or on the chair for comfort.
Step 3: Keep your back straight and shoulders relaxed to maintain the natural curve of your spine.
The half-standing, half-sitting position helps distribute body weight evenly between the soles of your feet and the seat cushion, supporting comfort and reducing pressure on the spine, especially during long working hours. Additionally, this posture helps reduce fatigue and improve blood circulation by allowing the body to change positions flexibly, avoiding prolonged sitting.

2. Common Mistakes in Sitting Posture
Sitting incorrectly for extended periods can lead to various health issues and negatively impact workers' mental well-being. Here are eight common mistakes in sitting posture to avoid:
Leaning Forward Without Back Support: Sitting forward without leaning back places continuous strain on your spine, particularly in the lumbar region. Over time, this can lead to lower back pain, muscle tension, and negatively affect health.
Crossing Your Legs: Sitting with crossed legs can obstruct blood circulation, increasing the risk of varicose veins and disrupting the body’s natural balance. This can lead to hip and knee issues when sitting for long periods.
Tilting Your Head Back: This position strains the neck and upper back muscles, potentially causing neck fatigue, headaches, and stiffness in the neck joints. Prolonged sitting in this manner increases the risk of cervical spine degeneration.
Leaning Too Deeply Against the Backrest: Leaning too far back can cause the body to slide forward, eliminating support for the lumbar area and spine. This can result in lower back pain and uneven pressure on the spine, leading to fatigue and muscle damage.
Bending Your Wrists: Bending your wrists for long periods while using a computer can lead to carpal tunnel syndrome, causing numbness, pain, and weakness in the hands. This position strains the muscles and nerves in the wrist, affecting hand mobility.
Twisting to Alleviate Back Pain: Twisting your body to relieve back discomfort can strain back muscles and the spine, causing pain and discomfort. Maintaining this habit significantly increases the risk of spinal injuries and herniated discs.
Slouching to One Side: Habitually leaning to one side, often seen in those who rest their upper body on the desk, disrupts spinal balance and causes muscle strain. Over time, this can lead to chronic back pain, spinal misalignment, and even hunching.
Feet Not Flat on the Floor: When your feet aren’t flat on the ground, your body lacks proper support, increasing pressure on the lower back and thighs. This can lead to spinal stress, leg muscle fatigue, and decreased blood circulation in the lower extremities.
3. Tips for Productive and Comfortable Work All Day
Here are four tips to help you maintain a correct sitting posture that promotes productivity and comfort throughout the day.
3.1. Choose the Right Office Chair
Selecting a suitable office chair is crucial for your health and work efficiency. A low-quality or incompatible chair can lead to problems like back pain, neck strain, decreased work performance, and long-term mental health issues. Especially, poor sitting posture over time increases the risk of spinal and musculoskeletal disorders, such as herniated discs and cervical spine degeneration.
To ensure health and work efficiency, you should select an office chair that has the following characteristics:
Suitability for Usage Needs: The office chair should meet your specific work requirements and style. If your job requires long hours of sitting, choose a chair that provides support for the spine and lower back. If you want to switch flexibly between working and resting, look for a chair with adjustable features (like height adjustment and backrest tilt) to easily customize it to your preferences.
Soft, Comfortable Materials: Opt for a chair made of breathable and resilient materials to maintain comfort throughout your working hours, reducing feelings of stiffness and heat. A chair with multi-density cushioning, like those from Okamura, not only provides softness but also distributes pressure evenly, minimizing stress on contact points like the back and hips.
Adjustable Features: A good office chair should have adjustable height, backrest, and armrests to accommodate different body types and sitting postures. These features help users easily modify the chair for optimal comfort and prevent issues related to poor posture.
Ergonomic Design: An ergonomic office chair is designed to support proper sitting posture, helping to reduce pressure on the spine, neck, shoulders, and lower back. To determine if a chair is ergonomic, check if it supports the natural curve of the back, has lumbar cushioning, and offers height and backrest adjustments. These elements help maintain correct sitting posture, reduce strain, and improve work efficiency.
3.2. Develop a Habit of Changing Sitting Positions
Frequently changing your sitting position can relieve pressure on the spine and improve blood circulation, effectively preventing chronic health issues. According to the ergonomics research team at Cornell University, sitting continuously for more than 20 minutes can have negative effects on the body and increase the risk of musculoskeletal problems (such as back and neck pain).
Here are some rules to help you effectively change your sitting posture:
Change Position Every 30-60 Minutes: After sitting for 30-60 minutes in a fixed position, adjust the backrest tilt or stand up to move around gently. This will help relax your body and prevent stress on the spine.
Use a Chair with Flexible Adjustment Features: Utilizing an office chair with adjustable height, backrest, and tilt angle allows you to easily change positions while maintaining comfort. A flexible chair enables you to adapt to different postures, minimizing body strain and enhancing work efficiency.
3.3. Balancing Work and Rest Time
Sitting for long periods in one position while continuously using your brain can lead to stress, fatigue, and musculoskeletal issues for office workers. Therefore, effectively balancing work and rest time is key to maintaining long-term productivity and protecting your health. Additionally, proper rest not only helps the body recover but also enhances creativity and focus.
Here are three effective ways to manage your work and rest time:
The 20-20-20 Rule: Every 20 minutes of work, take 20 seconds to look at something at least 20 feet (about 6 meters) away. This rule helps relax your eyes, reducing eye strain from prolonged screen time, while also improving concentration.
Establish Short Breaks: Take short breaks of 5-10 minutes after every 1-2 hours of work. Activities such as standing up, walking around, or doing light exercises will improve blood circulation, reduce pressure on the spine and muscles, and refresh your mind for continued effective work.
Use Your Lunch Break Effectively: Instead of sitting in place during your lunch break, utilize this time to go outside for fresh air or engage in light activities like walking or doing some simple stretching. This not only alleviates stress but also helps you recharge, maintaining your focus for the afternoon.
3.4. Perform Supportive Exercises
Incorporating supportive exercises during work is an effective way to minimize fatigue and help relax the body. Gentle exercises can relieve tension in muscle groups and prevent long-term musculoskeletal issues.
Here are some supportive exercises you can try:
Gentle Neck Rotations: Sit up straight, maintaining a natural posture or leaning against your chair. Start by rotating your neck clockwise from left to front, then to the right and back. After that, rotate counterclockwise for another 10 seconds.
Shoulder Stretch: You can do this exercise while standing or sitting, but make sure to keep your back straight. First, bring your right arm across your chest, ensuring the elbow is straight. Then, use your left hand to gently pull your right arm toward your left shoulder, feeling the stretch in your shoulder and arm. Hold this position for about 15-20 seconds, then relax and switch sides.
Arm Stretch: Extend both arms in front of you, interlace your fingers, and turn your palms outward. Then, stretch your arms forward. Hold this position for 10-15 seconds for best results.
Lower Back Stretch: Sit upright in your chair with your feet flat on the floor and your hands resting on your knees. Slowly lean forward while keeping your back straight to feel the stretch in your lower back. Hold this position for 10-15 seconds, then return to an upright position and repeat several times to relax and relieve tension.
To maintain health and work efficiency, it's crucial to pay attention to proper sitting posture, develop movement habits, and use a suitable office chair. By implementing these practices, you can cultivate good habits for long-term health, while choosing quality supportive products like Okamura office chairs will help you remain comfortable and active in your work.
