Is it better to sit for a long time at work or a low stool, or a high stool?

For sedentary workers at work, it is advisable to choose an ergonomic chair, specifically:

1.Seat height: The height of a good chair is generally between 39 and 42 cm, which can make people maintain a correct sitting posture without putting their legs in a suspended state and reduce the occurrence of chronic strain.

2.Backrest design: The backrest of the chair is also very particular, and the backrest should not be too straight, because the human spine has several physiological curves, and a backrest that is too straight is easy to cause backache; The low height of the backrest can reach the user's first and second lumbar vertebrae, and the high height can reach the user's neck, which is convenient for supporting the head.

3.Tilt angle: The backrest inclination of the chair is also particular, generally speaking, the backrest inclination is gradually increased backwards, and it is appropriate to be around 110 degrees.

4.Handle design: The chair with a handle can also help support part of the weight of the upper limb and reduce the burden on the intervertebral discs.

5.Material hardness: The chair should not be too soft, because when people are sitting, the load on the lumbar spine is greater than when standing, and a chair that is too soft is easy to make the lumbar spine bend too much, resulting in back pain.

To sum up, choosing an ergonomic chair is the best choice for sedentary workers at work. Specifically, the chair should have features such as appropriate seat height, backrest design, reclining angle, handle design, and material hardness. At the same time, users can adjust the height and comfort of the chair according to their physical characteristics and needs to maintain a correct sitting posture and reduce damage to the body.

It is better to be shorter, a high stool is easy to sit on with a hunched chest, and a low stool is just the opposite.

The height is determined according to the height of the table.

The optimal height difference between a table and a stool is in the range of 280 to 320 mm, which is more in line with human physiology. For the height of tables and chairs, the state has set standards.

Among them, the standard height of table furniture can be 700 mm, 720 mm, 740 mm, 760 mm, four specifications; The seat height of the stool furniture can be 400mm, 420mm, 440mm, three specifications. In addition, the standard size of tables and chairs is specified, and the height difference between tables and chairs should be controlled in the range of 280 to 320 mm.

The correct height of the table and chair should be able to maintain two vertical verticals while sitting, one is that the thighs and calves can be basically vertical when both feet are on the floor, and then the seat on the front edge cannot put pressure on the plane of the lower thighs. Second, when the arm is naturally downward, the upper part of the arm is basically perpendicular to the lower part of the arm, and the height of the table should just be in contact with the lower plane of the lower part of the arm.

This will allow people to maintain a correct sitting and writing posture. If the height of the table and chair is reasonably mismatched, it will directly affect the posture of the person sitting, which is not good for the user's health. In addition, the space under the writing board is not less than 580mm, and the width of the space is not less than 520mm.

Whether it is the height of a writing desk or desk, or the height of a keyboard and mouse on a computer desk, it should be the same height or slightly lower than the height of the person's elbow when sitting. The top of the monitor should not be higher than the eye level in a sitting position, otherwise vision will be reduced.

The height of the stool is determined according to the height of the person using the stool and the needs of the user. If it is a normal need for study, eating and other daily needs, the height of the stool should be the best for the user to sit on the stool with his feet just straight with the ground, and if it is used in a bar or in front of a song hall microphone, the stool should be slightly higher. It is best to sit on a stool with your feet just below the ground.

In fact, no matter how you sit, as long as your upper body remains straight, but sitting higher is easier to keep your upper body straight.
