An improperly adjusted chair, a poor fitting chair, unsupported feet, sitting too long without a break or change of positions can cause discomfort in the lower extremities.
Experience pain in hips, legs and knees while sitting
In many situations, pain is caused by a chair seat not being raised high enough or the depth of the seat pan set too short. If you have an adjustable ergonomic chair, raise the height of the seat pan so that the hips and knees are set at right angles, legs dropping straight with feet placed comfortably onto the floor. The front edge of the seat pan should be approximately 2 inches behind the back of the knee to provide adequate support for the hip, leg and even the lower back.
In other situation, pain can be caused by the seat pan being raised too high and/or the seat pan set too deep. If the chair is adjustable, make adjustments as noted above. If a properly fitting ergonomic chair is not available, purchase and adjust appropriately. See our chair section.
Pressure on the back of the knees Legs don’t feel supported.
Dangling feet can put pressure on the thighs and the back of knees, cutting off circulation to lower legs and feet. Legs should rest comfortably onto floor or on a footrest. (See our Footrest Section)
