What is Computer Workstation Setup?
Workstation setup and use for people who work regularly at computers.

More questions, answered
Is a standing desk better than sitting?
A sit-stand desk can help because it makes changing position easy, but standing all day brings its own problems, including leg and foot discomfort. The benefit comes from alternating between sitting, standing and moving rather than from replacing one fixed posture with another.
Do I need an expensive ergonomic chair?
Not necessarily. What matters is that the chair adjusts to fit you: seat height, backrest height and angle, and ideally armrests that do not stop you getting close to the desk. A modest chair that fits well and is properly adjusted is better than an expensive one set up badly.
Can screens permanently damage my eyes?
According to eye specialists, computer use causes eye strain and dryness but does not permanently damage the eyes. Symptoms usually ease with rest, regular breaks, blinking and the right glasses. Persistent problems should still be checked, as they may point to an uncorrected vision issue.
Are wrist rests helpful?
A wrist rest can support your hands during pauses in typing, but resting your wrists on it while you type can bend them and press on the underside of the wrist. Aim to keep your wrists straight and floating while typing, using the rest only between bursts.
What about blue light glasses?
Eye care organizations do not currently recommend blue light glasses for computer use, as there is no good evidence that blue light from screens damages the eyes or causes eye strain. Breaks, blinking and correct glasses for screen distance are more useful.
How high should my keyboard be?
Your keyboard should sit at about elbow height so you can type with relaxed shoulders, elbows close to your sides and wrists straight. If the desk is too high, raise the chair and add a footrest; if you can, use an adjustable keyboard tray.
