Goodbye manual adjustments. 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 be constricted by locking mechanisms and manual controls. In other words, sitting comfortably isn't something you should have to think about. The Freedom chair was designed specifically to encourage frequent, spontaneous changes of position. There are no locks and no tension springs to negotiate. Instead, there are elegant mechanisms that automatically support your body in every position you'll assume throughout the day. Headrests are added to chairs because your head needs support when you recline, which is why people without headrests put their hands behind their heads when they lean back. However, fixed or manually adjusted headrests are never in the right place when you need them. The dynamic, position sensitive headrest on Freedom cradles your head and neck as you recline, and moves out of the way when you sit upright automatically!
