What is the lowest height of a computer chair?#Office computer chair

The appropriate height of the computer chair is relative to the computer desk. The healthy sitting posture of people who often use computers should meet the "three right angles."

The three right angles mean:
The calf at the knee forms a right angle with the thigh; the hip and waist form a right angle; the elbow joint of the forearm forms a right angle. As long as these three right angles are achieved, the body will not be tilted back or forward excessively due to discomfort in the neck.
A healthy sitting posture allows the bones to evenly bear the weight of all parts of the body. We need to keep the upper body straight, especially the neck, and we need to stand upright to support the head, and the shoulders should be naturally drooped, as close to the body as possible, and the elbows should be bent about 90°.
When operating the keyboard or mouse, do not raise your wrist, otherwise the wrist joint is very easy to fatigue. Keep your wrist in a horizontal position as much as possible.
Don’t keep your palms in an adducted or outstretched posture, and it’s best to keep them in a straight line with your forearms. To protect the lumbar spine, you should sit straight and your waist should be straight, so that your knees will naturally bend about 90° and maintain a sitting posture with your feet on the ground.
To achieve three right angles, the collaboration between the table and the chair is required. The so-called "one slap does not sound", no matter how ergonomic a single table or chair is, it cannot achieve the comfortable effect of "three right angles".
