Continuous standing or sitting while working is a common source of discomfort and fatigue. Frequent changes of body positions, including alternating between sitting and standing, helps to avoid fatigue.

Arrange work in a semi-circle. Use a swivel chair to reduce body twisting, to allow easy movements, and to reduce side-to-side motions. Use sloping work tables whenever possible to reduce bending, and to encourage an upright position while sitting or standing.

What are examples of a chair for sitting/standing workstations?

Whenever possible, a worker should be able to work sitting or standing at will. Ensure that the seat has a minimum width of 40 cm (about 16 in.). Choose back rests that are contoured vertically and horizontally. Use a seat covering of non-slip, breathable fabric. Select seat padding that is about 2-3 cm (1 in.) thick.

• Provide a chair that can fold up and be stored out of the way where space is limited.
• Ensure that chairs have a back support.
• Provide a chair for resting purposes even when work can only be done standing.
