Knee Chair

Kneeling chair is a type of chair. Kneeling chairs have been recommended by medical professionals around the world. It is alo known Balans chair. Kneeling chair position with the thighs dropped to an angle of about 60 to 70 degrees from vertical (as opposed to 90 degrees when sitting in a normal chair), with some of the body's weight supported by the shins. Kneeling chairs sought to open up the angle between the thigh and the spine, making it easier to retain the natural curvature of the lower back (the lumbar ).

Lumbar is an adjective that means of or pertaining to the abdominal segment of the torso , between the diaphragm and the sacrum ( pelvis ) . The five vertebrae in the lumbar region of the back are the largest and strongest in the spinal column . In most mammals , the lumbar region of the spine curves outward; this is called lordosis. Despite the name, the posture of a person in a kneeling chair is not the same as kneeling on the ground.

It is sometimes assumed that the knees bear most of the body's weight when sitting in a kneeling chair, but this is incorrect--the shins bear some weight for stability, but you are still sitting (not kneeling). This posture changes the stress distribution of the human body in comparison with the sitting position of an ordinary chair and is recommended for certain diseases or injuries of the backbone . Because the angle of the hip joint is between that of sitting and standing. This chair differs from other kneeling chairs by incorporating an adjustable backrest (lumbar support). Kneelsit's innovation is the mounting of the seat and kneeler on swivel-axle bearings. This allows for continuous movement in the body of the user.
