The MI-7803 is an under-desk, ergonomic footrest that will keep you working comfortably. Raise your feet and legs for better posture and less strain. Improve your circulation with the massaging, round surface bumps. Tilt setting goes from 0 to 15 degrees so you can adjust the footrest to your leg length. Non-skid surface keeps your feet from slipping off the footrest while working. Low-profile takes up minimal space under your desk or stored away.
