There are some chairs at office depot that has this feature. I plan on buying one for moderate home usage. They state that you should lower the tension for lighter people and raise the tension for heavier people. But exactly how does the feature help prolong th elife of the chair. I am actually neither heavy or light in weight. And i want to prolong the life as long as possible.

How many ways can seven people sit in seven chairs if the chairs are arranged in a circle, and order matters? Hint: the head position is not fixed. To answer this you must consider how the circular arrangement arranges things.
