Why is it important to work from the correct computer task chair height?

When working from a computer desk, your task chair must be the correct height, and achieving this will bring a range of benefits. These main benefits include:

  • Reduced risk of long-term injury and musculoskeletal disorders: Having a poorly adjusted task chair will cause you to be in unsupported positions for prolonged periods a day. This poor posture can lead to long-term injuries in several parts of your body, and cause musculoskeletal disorders. These disorders cause major damage in the muscles, spine, tendons and nerves, leading to pain, rigid movement, and even paralysis. When your chair height is positioned correctly, your body is constantly in a healthy, supported posture that reduces the chances of these injuries or disorders occurring.
  • Reduced risk of back, neck and shoulder pain: Having an ergonomic task chair at the right height can reduce the likelihood of you getting back, neck and shoulder pain. When your chair is positioned at the wrong height, your body must move into an unsafe position to work on the computer monitor, and this puts persistent pressure on the spine which causes nerve constriction and disk degeneration. This will cause severe pain and unsafe movement in your back, neck, and shoulders.
  • Avoiding eye strain: Eye strain can occur when you are staring for long periods at a computer monitor that is not in accordance with your chair height. Your eyes can begin to feel pain and turn red, and you may experience blurred vision and severe headaches. When your chair is set at the right height to have your monitor at eye level, your eyes will be in a much safer position to view your screen without looking too far up or down and straining them.

  • Improved comfort and productivity: Ergonomic chairs with the right height improve your overall comfort at your workstation at all times. This daily comfort not only reduces injury risks, but also allows you to focus more on your work and productivity without being distracted by discomfort or pain.

How to ensure your task chair is the correct height

Now that you know the importance of having a correct task chair height, here is a guide on how to ensure this is achieved:

1. Make sure your feet are firmly planted on the ground when you are sitting. If you find you are on your toes, or your feet barely touch the ground, this means that your seat is too high and must be lowered.

2. Your knees must be at a 90-degree angle that is parallel to your hips. If your knees come above your waist, this means that your chair is too low and must be raised.

3. Your chair must adequately support your upper and lower back. Your back has a natural curvature, so you must make sure the backrest of your chair is at the right height to support this curve. A chair that’s too high will result in you leaning forward to work, which disrupts the natural back support posture.

Benefits of working from an adjustable chair

Adjustable chairs are the perfect way to ensure that every aspect of your body’s positioning is set up in a correct and healthy manner. Firstly, your chair can be adjusted according to your specific height, meaning that you most certainly can find the right position for you. Adjustable chairs are also perfect for comfort and easy use, and with a more comfortable chair, you are primed and ready for a highly productive working day without the hassle of discomfort or pain.

What should an ergonomic task chair consist of?

Along with being set at the correct height, these are a few more things that are essential for a healthy task chair setup:

  • Armrest support – Armrests are great for allowing you to use your laptop and keyboard without straining your arms or shoulders. The ideal setup is to have your arms bent at a 90-degree angle and your elbows level with your desk and keyboard.
  • Backrest support – Your backrest should be sufficiently set up to avoid any poor posture which can lead to injury. The natural curvature of your back must be supported by an inward curve in the backrest, to ensure a safe and comfortable position for your back, neck and shoulders to rest in.
  • Your feet should be supported – If your feet aren’t planted on the ground, you may benefit from a footstool that can make sure your feet achieve this positioning.
