Ergonomy: Lumbar and Thigh Support
The lumbar is the region of the spine between the diaphragm and the pelvis; it supports the most weight and is the most flexible. The adjustable lumbar mechanisms in seats allow the user to change the seat back shape in this region, to make it more comfortable. Some seats are long enough to support full thigh.

Famous quotes containing the word support:
“They [parents] can help the children work out schedules for homework, play, and television that minimize the conflicts involved in what to do first. They can offer moral support and encouragement to persist, to try again, to struggle for understanding and mastery. And they can share a child’s pleasure in mastery and accomplishment. But they must not do the job for the children.”
—Dorothy H. Cohen (20th century)
