Distance between desk and chair


The proper posture towards a screen includes a slight downward viewing angle (screen centred with keyboard) and a eye-to-screen distance between 500 and 700 mm. These can also result from the use of the mouse since several studies have put forward the link between the intensive use of the mouse and neck, shoulder or arm pain. The wrist is also sensitive to pressure as it supports the hand’s weight and also because of the pressure of the bending angle. Increasing the angle of bend increases the contact stress and irritation on tendons and tendon sheathes.
Water drop shape, not too sensitive buttons are crucial elements when it comes to the choice of a good mouse.

The proper posture towards a screen, keyboard and mouse include:
• straight neck
• slight downward viewing angle (screen centred with keyboard)
• eye-to-screen distance between 500 and 700 mm
• forearms parallel to the floor
• wrists straight
• palms resting on a soft surface when not typing on the keyboard
