Horizon's footrests are made from a solid and sustainable product design. They are adjustable at several heights. The unique footplate has a rubber non-slip cover and provides optimal comfort and stimulates the blood circulation. The angle of the foot rest can be adjusted with a single foot movement, so that the ankle can always be kept at a 90� angle.This encourages you to stretch your legs from time to time. Apart from a welcome change in position, and a good working posture, it helps to prevent stiffness, swollen or cold feet and varicose veins. Using a footrest will help you to create a healthy and comfortable working environment. Lifetime warranty!
