The Freedom chair is designed to give the maximum ergonomic benefit to the sitter with a minimum number of manually-adjusted controls. Once the chair is fitted, no further adjustment is required. The idea is that movement, which is essential for a healthy body, shouldn't it be constricted by locking mechanisms and manual controls. In other words, sitting comfortably isn't something you should have to think about.
The FM100 offering a stable yet dynamically adjustable foot support, packs a lot of features into a value-priced package.
The and FM300B, with their ball bearing rollers, encourage gentle rocking of the feet in the same way a rocking chair encourages movement.
