Setting up your workstation properly is crucial. Even with well-designed and adjustable equipment, if the workstation is set up incorrectly, awkward postures are likely, which will increase the risk for injury. Follow tips as outlined below, consider an ergonomic evaluation, or attend an online or instructor-led training session.
The chair is one of the most used pieces of equipment in the office and needs to be adjusted to fit correctly. A poor-fitting chair can have many detrimental effects on posture. Ensure the chair adjustments are understood and it is adjusted and used correctly.
When sitting in a chair, sit back completely to ensure back support. Adjust the height so that the feet are flat on the floor or a footrest, thighs are about parallel to the ground and knees and hips in ~90-110 degree angles.
Even when a chair is adjusted correctly to fit the body, it may not be used in the most beneficial manner. Movement is crucial. We often sit in static posture without movement and are told to ‘sit up straight’ when this is not the most ideal way to sit. Review the below video for a brief illustration on sitting and the use of “dynamic” postures.
The top of your computer monitor should be placed at or slightly below seated eye level and about an arm’s length away. Ensure the size of the text on the screen can be seen without straining the eyes and without leaning forward with the back or neck.
Use of more than one monitor requires consideration of the duration of use the monitor is used. If using two monitors they should be placed as close to one another as possible and if used equally, they should be arranged so that the split between the two is right in the middle of the body to help minimize neck twisting. If using one predominantly, that monitor should be placed directly in front of the body with the less frequently used monitor to either side.
Recommended Dual Monitor Setup
Document holders are useful if there is any referencing from books, paper materials such as handwritten notes, etc. Ideally, given most individuals have more than one monitor, the document holder should be positioned just below the monitor and above and behind the keyboard (see illustrations below). Document holders should also be sturdy enough to write on (make notes, highlight, cross things off). Placement of the document holder in this location can help minimize excessive and repetitive awkward neck and/or back postures to view the paper documents.
Both the keyboard and mouse should be adjusted to about elbow height or slightly lower. This should allow for the shoulders and upper back to relax. The shoulders and upper arms should hang naturally by your sides with the elbows in ~90-110° angles with the forearms about parallel to the ground. An ergonomically designed desk/table should fit a majority of the working population to allow for ideal working elbow postures. (Tables should adjust from ~22-48″). Without proper adjustment, elbow and shoulder postures may suffer. This can increase the risk for injury with extended durations.
Standing posture should be much the same as sitting. Elbows bent at ~90 degrees, shoulders relaxed, elbows close to the body with the forearms about parallel to the ground. (Pictures below illustrate ideal working postures (to start). See the below videos for additional information and illustration.
The keyboard and mouse should allow for a straight wrist posture. There should be no bending of the wrist whether up, down, left or right. If a wrist rest or palm rest is used, it should be a soft material like foam or gel and ideally, should only be used during periods of rest (breaks, when typing/mousing is not taking place). Avoid planting the wrists/palms on the rest for extended periods. Consider trying equipment in the ergo lab prior to purchase.
Avoid cradling the phone for extended durations. Use a headset or use the speakerphone.

Learn to adjust and use all of the furniture and equipment features at your workstation to improve your workstation setup, improve comfort and decrease risk for injury. Even with changes, do not ignore the injury risks. It is highly recommended to seek advice from an ergonomics specialist. Visit the ergo lab to try available equipment and receive further education on tools, equipment setup and overall ergonomics. Complete online and/or instructor-led training to learn more.
