Long periods of standing at work can lead to back problems as well as problems with the legs and feet. This can create tension, stiffness, inflammation and even varicose veins. The result is lost time due to illness and low productivity due to fatigue and discomfort. A useful contribution to on-the-job safety and employee well-being is to equip workstations with special anti-fatigue mats. The Kleen-Foam mat is a simple and effective way to provide relief for employees who are subjected to the fatigue caused by standing for long periods.
