Whether in the office or at home, it is a habit of many young people to sit in front of the computer without fighting. If the time is long, there will be problems such as blurred eyes and backache. This is because if the computer chair and the desk are not matched enough, it is easy to cause damage to the eyes and joints. So why not pick a suitable computer chair?
How to choose a comfortable computer chair
The height of the computer chair should be based on the "reference object": many people's office chair height is not up to standard, so that the body can not be freed from back pain. So, how can I adjust the office chair to the "best state"? First adjust the desk or workbench to the right height according to the nature of the work. Because different desk heights have different requirements for the placement of the seat, and sometimes even a seat is required. Once the height of the desk is fixed, the height of the seat can be adjusted by using the desk and body height as a "reference".
Try to choose an adjustable function: a good computer chair should not only be comfortable, but also have a high degree of freedom in both the vertical and horizontal directions, that is, the adjustable range is large. The good seat has a dual pneumatic function, which can adjust the height of the chair and adjust the pitch angle of the seat back. When shopping, you can sit down and feel whether the back of the chair is soft and moderate, whether the curve of the back of the chair fits the curvature of the human spine, fully support the back, whether the waist can relieve the excessive pressure load on the back, and ensure the correct sitting position; Whether it is wide and thick, comprehensive support, can not only reduce the impact of the body's weight when sitting down, but also relieve the pressure on the buttocks during long-term work, relax the body and mind, and improve work efficiency. At the same time, we must pay attention to the selection of the casters: whether it is safe and smooth, whether it can rotate freely on the carpet, whether the plastic texture of the roller is too hard to damage the floor.
Put a cushion to maintain the sitting position: the cushion can really relieve the people with lumbar muscle strain, but there are also a lot of stress when using the cushion. First of all, the cushion must be placed at the waist, and it is not effective to put it on the back. This is because the normal human body has three physiological curvatures. Because of physiological requirements, they do not grow in a straight line. The thoracic vertebrae are convex, and the cervical and lumbar vertebrae are convex forward. From the side, the spine is like the connection of two S. Due to this physiological feature, the waist and back cannot be placed on the same plane. Secondly, the thickness of the cushion should be appropriate. Can not be too thin and too soft, so that it can not lift the waist, not too thick and too hard, too thick may cause excessive flexion of the lumbar spine, and too hard will be uncomfortable. The cushion can be placed behind the waist during the selection. If the cushion still feels comfortable after ten minutes, the thickness is suitable. If the back is tired or even painful, the cushion is unqualified. Furthermore, people who already have lumbar disc herniation and lumbar spinal stenosis should pay more attention to the comfort of the cushion.
