If choosing a chair with arm rests ensure: |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
■ They are fully adjustable within the height restrictions of your desk |
■ They do not cause you to hunch your shoulders |
■ You do not rest your arms on them whilst typing / writing etc. |
Maintaining the Correct Posture - |
■ Always sit with the knees lower than the hips. |
■ Ensure that you are not stretching to reach your keyboard and mouse. Move in closer to the desk or re-arrange your desktop if necessary. |
■ Sit with your eyes at least 250mm away from your monitor. Preferably have your monitor positioned at eye level. If this isn’t possible tilt the top of the monitor so that it is slightly further back than the bottom. |
■ Always maintain a good posture whilst seated, try not to slump into the chair. If you find yourself slumping, have a break and walk around the office to invigorate your muscles. |
■ Never stay seated for extended periods. Get up and walk around for at least 5 minutes in every hour. |
Prevention is better than cure - |
Always research well and choose the right chair for the job. Back problems significantly affect productivity at work and can be easily avoided by choosing the right equipment. |
If you’re choosing a chair for someone else, consult with them when making the choice. If the chair is to be shared, make sure it is fully adjustable to suit all users. |
Regulations - |
Remember to check that the chair you buy is compliant with the rules and regulations applicable to your company and the building you work in. For example, always check if you require fire retardant furniture and furnishings in your office. |
