FR500

The award-winning FR500 delivers effortless functionality in a simple, stylish package. Like all Humanscale Foot Rockers, the FR500 promotes health and comfort by getting the user’s feet moving. This addition to the workstation provides instant relief from prolonged sitting by encouraging a gentle rocking of the feet.
The FR500 Foot Rockers provides perfect support for the feet and legs when sitting. By engaging lower leg muscles, it increases healthful circulation while also raising the feet to relieve pressure on the lower back.
Designed with a graceful curvature, the FR500 encourages users to get their legs and feet moving. Its innovative design ensures the user’s feet stay firmly planted on the foot rest so the user can gently rock all day long.
