🪑 How to Adjust Your Office Chair Properly to Avoid Back Pain
If you work or study at a desk for long periods, it is important to sit on an office chair adjusted to fit your body properly. Sitting incorrectly can lead to back pain and spinal problems.
Orthopedic doctors and physical therapists indicate that sitting for long periods on unsuitable office chairs may cause overstretching of spinal ligaments and problems with the intervertebral discs.
The good news is that adjusting an office chair is simple and only takes a few minutes if you know the correct steps.
⚙️ Steps to Properly Adjust Your Office Chair
1️⃣ Set the Correct Desk Height
Start by determining the proper height of your desk.
✔ Ideally, your desk height should be adjustable.
✔ If it is not adjustable, adjust the chair height to match the desk.
2️⃣ Check the Angle of Your Elbows
Sit comfortably close to the desk.
✔ Your upper arms should be parallel to your spine.
✔ Place your hands on the keyboard or desk surface.
✔ Your elbows should form an angle of about 90 degrees.
3️⃣ Adjust the Seat Height
Locate the height adjustment lever under the chair seat.
🔹 If your hands are higher than your elbows
➡️ The seat is too low and should be raised.
🔹 If the seat is too high
➡️ Press the lever while sitting to lower the seat until it reaches the desired height.
4️⃣ Make Sure Your Feet Are in the Correct Position
Sit with your feet flat on the floor.
✔ Slide your fingers between your thigh and the front edge of the chair.
✔ There should be a small space about the width of a finger.
📌 If you are very tall
You may need to raise both the desk and the chair.
📌 If you cannot slide your fingers under your thigh
You can use an adjustable footrest.
5️⃣ Measure the Seat Depth
Measure the distance between the back of your calves and the front edge of the chair.
✋ Try to fit your fist in the gap.
✔ The ideal distance is about 5 cm (2 inches).
🔹 If your fist does not fit easily
➡️ The seat is too deep and the backrest should be moved forward.
🔹 If the gap is too large
➡️ Move the backrest slightly backward.
💡 Correct seat depth helps prevent slouching and protects the lower back.
6️⃣ Adjust the Backrest Height
Sit upright and adjust the backrest.
✔ It should support the natural curve of your lower back.
✔ You should feel strong support in the lower back area.
Most chairs have a knob behind the chair that allows you to raise or lower the backrest.
7️⃣ Adjust the Backrest Tilt
The backrest should be slightly tilted to support your back.
✔ You should not need to lean forward.
✔ You should also not lean too far backward.
Use the knob behind the chair to adjust the tilt angle until you find the most comfortable position.
8️⃣ Adjust the Armrests
Armrests should support your elbows without raising them.
✔ The armrests should lightly touch your elbows.
✔ Your elbows should remain at a 90-degree angle.
✔ Your arms should move freely.
📌 Note: Not all chairs have adjustable armrests.
💡 Important Tips for Healthy Sitting
🔹 Keep your back straight while working.
🔹 Avoid leaning forward for long periods.
🔹 Stand up and move every 30 minutes.
🔹 Do stretching exercises to reduce pressure on your back.
⭐ A properly adjusted office chair can protect you from back pain and improve your productivity while working.
