Adjustable monitor arms enable easy height adjustment for workstations with multiple users. A well-designed chair will favorably affect posture and the amount of strain on the back. An adjustable seat back is best for support in the lumbar region. The user should be able to adjust seat height and seat pan angle from a seated position. Armrests are optional.
Additional accessories can improve operator comfort.
Document holders can minimize eye, neck, and shoulder strain by positioning the document close to the monitor. A footrest should be used if the feet cannot be placed firmly on the floor. Task lamps will illuminate source documents when room lighting is reduced. Glare should be eliminated through methods that include reduction of room lighting, shielding windows with shades, curtains or blinds, positioning the terminal at a right angle to windows, and tilting the monitor to avoid reflection from overhead lighting. Glare screens are not normally necessary.
