Workstation myths

Many generally accepted guidelines for posture and furniture at computer workstations are, in reality, myths. If rigidly followed, these misconceptions can lead to uncomfortable and costly mistakes. Some of these myths include:

Correct posture at the computer eliminates discomfort and possible injury.

“Picture-perfect” posture can be extremely fatiguing. When sitting, the full force of gravity is carried by the upper body and can lead to fatigue, muscle strain, or joint pain. The best posture is dynamic in nature. Change your position frequently, alternating sitting and standing.

Computer operators should sit upright at the computer.

If given a choice, four out of five workers prefer to sit slightly reclined. A reclined posture is easier to maintain than sitting erect. Sitting slightly reclined also reduces pressure on the discs in your lower back.

Height adjustable chairs enable you to work at any height table.

In some situations, chair height adjustments won’t result in safe work postures at a desk or table. If the table top is too low, lowering the chair can result in an awkward position that places extra pressure on your legs and back. A better alternative would be to raise the desk on blocks.

Petite workers can have difficulty working at a standard or high desktop. If the chair is elevated to work comfortably, feet can dangle above the floor. Footrests can provide foot support in this situation, but may not accommodate all positions a worker might need to reach equipment or complete all work tasks. The best solution is to lower the desk or change the work task to eliminate the need for forward reaching.

Ergonomic chairs are designed to fit all users.

Everyone is shaped differently. Women generally have larger hips than men and need a chair with a higher lumbar back support and a wider seat area. Men frequently have longer legs and need a deeper seat area. When selecting a chair, consider your individual needs.

Adjustable work stations are the best office furniture.

Most work stations require adjusting work surfaces manually which is often inconvenient and time-consuming. A better solution is to place keyboards and monitors on flexible, counter-balanced arms that can be adjusted to accommodate a variety of workers and work postures.

Don’t be hurt by workstation myths. Make sure your furniture and chair are adequate for your needs and use good work habits. Change postures and take frequent short breaks throughout the day.
