Leveraging 20 years of ergonomic expertise, Kensington's patented SmartFit System gives you the power to customize your foot rest for enhanced comfort. The Solemate Plus Foot Rest has an anti-skid surface and supports your legs at the optimum angle to reduce muscle strain and fatigue for all-day comfort. The professional-level customization lets you measure, adjust, and fit your foot rest without the need for an ergonomist. The height adjusts to match your personal SmartFit comfort color, and with a flick of the foot-operated pedal, you can adjust the tilt angle to your ideal setting. Height adjusts from 3.5'' to 5". Angle adjusts 30 degrees and locks into place with a simple press of the foot. Features a non-skid surface.
