How to sit on a Chair?
Those who have to sit on a chair for long hours e g.
business executive, judges and magistrates, students, clerks etc. should make
sure that they are using the proper chair. The height of the chair should be
such that while sitting on it, the feet are placed flat on the ground. The
knees are at the same or a slightly higher level than the hips and the back is
touching the back support of the chair. If for some reasons a high chair has to
be used then a foot board should be placed under the feet to achieve the same
effect.
