Your feet should always be firmly supported when sitting and working. When feet are left dangling, poor circulation in our feet and legs occurs. The footplate can easily pivot back and forth on the frame allowing you to mobilize your legs' circulation throughout the day. It also has a vinyl non-slip tread surface, so your feet won’t slide off! And unlike many flimsy footrests sold in office supply chains, the foot flexor is very stable and won't easily move out of place. This standard model is ideal for users between 5" and 5' 9" in height. In addition, it also aids in keeping your body in place while in the chair.
