Desks and chairs
When setting up your desk and chair, you should ensure that they are both at a comfortable height. Your forearms should level with the desk to ensure that your wrists are not bent while using a keyboard, and your hips should be above the knees, with your legs fitting easily under the tabletop.
Ensure that the back of the chair supports the curve of your back and takes some of the weight. Your chair should be set up in such a way that it is supportive rather than forcing you to have good posture. If you don’t have a suitable chair, a cushion can offer lumbar support.
The aim is to be able to read information on a well-positioned screen. This can be achieved by positioning your primary screen (if you have more than one, this is generally the largest) centrally to you, when you are seated. The screen should be approximately arm’s length away and ideally, the top of the screen should be at eye level. If you have to lean forward to read your screen, either increase the font size or bring the screen closer.
Input devices should be positioned so that your arms and shoulders can stay relaxed. When using a keyboard or mouse, you should keep your wrist and hands in a neutral, relaxed position. If you work from a laptop, you should look at getting a separate keyboard and mouse, enabling you to use a laptop stand to heighten the screen and maintain a strong posture.
