Workers should not stay seated, standing or otherwise static for long periods, so workstations should allow postures and movements to vary. Seating should have adjustable height and angle, a contoured backrest with lumbar support unless it interferes with the task, a swivel action, rounded edges, a five-point base with castors or gliders as suits the floor and a footrest where a workplace assessment shows it is needed. A seated position suits fine manipulation, close visual work needing sustained attention and foot pedal operation. Standing workers should have a chair, stool or support to alternate, a footrest large enough for the whole foot and, where possible, floor covering that cushions hard floors, and standing suits handling large heavy loads, forceful movements, reaching, frequent movement away from the position, no knee room or limited space. Work areas need space for the workers, others involved and equipment, for example enough room in an aged care bathroom for two workers, the client and a hoist, with allowance for bariatric patients.
