Reflex Anti-Fatigue Mats provide a dual action blend of sponge with vertical column support. The super resilient closed cell polymeric sponge base encourages the subtle movement of leg and calf muscles, which promotes blood flow to the heart. The solid domed Reflex surface is compliant, taking the shape of the foot and providing equal support over the entire footprint. At the same time, it becomes very aggressive, providing an upward vertical force and simple manipulation of areas of the feet. This relieves tension and breaks up patterns of stress in other parts of the body to an amazing extent. As time marches on, it marches on your feet and Reflex Anti-Fatigue Mats help to stimulate your feet and provide pivot point ease. The bonus is good circulation and healthful life.
