Chairs should not be too soft

The degree of softness and stiffness of the chair is also very important. Knowledge of the anatomy and physiology of the human body tells us that when sitting, the lumbar load on a person is larger than that on standing, the position of the spine and the pelvis should be vertical, and the vertical fixed position should be the muscles on both sides of the spine. Maintain. If the position of the spine and pelvis is shifted for a long time, the force of this system will be biased, which will easily lead to back muscle spasm and even bone damage. Over time, the user will feel back pain.

Chairs that are too soft can easily cause users to squat, and the muscles and bones of the body are unbalanced, resulting in back pain. In this case, the user should consider replacing the chair and choose a harder chair for himself. If he continues to use the original chair, the Ouyifeng furniture suggests that the hip should be moved back when sitting down so that the back is close to the back of the chair. Instead of being vacant, consider also adding a cushion to your waist as a support.

Seat height no lower than 39cm

A good seat design should make the center of gravity of the upper body of the user fall on the bones of the hips. The height of the seat should be set based on the reference point of the person's sitting position (scalpel nodal node). Generally, the height of the seat is 39 cm. Between ~42cm, if the height of the seat is less than 39cm, the user's knee will be arched, resulting in discomfort; when the height of the seat is greater than 50cm, the body pressure will be dispersed after the user sits down As far as the thighs, the user's inner thighs are stressed, which can cause serious swelling of the lower legs.

When the user is working for a long time, the chair with backrest can make the user feel more comfortable. In general, the height of the backrest is not fixed, depending on the user's habits and feelings. For the work chair, as long as it does not affect the user's activities, the backrest height can only reach the user's first and second lumbar vertebrae. The taller person can go to the user's scapula and neck; however, for a casual chair, the height of the backrest is appropriate to the neck, so it is better to support the user's head and facilitate the user to rest.

The seat should not be too narrow

When we want to choose a good and suitable chair, we must consider the chair's seat, backrest, handrails and other aspects. The width, depth, inclination, backrest curvature of the seat, etc. must meet the scale of the body and the rules of movement of each part.

The height of the seat, too high or too low, can cause the user's body to be injured. When choosing a seat, besides considering the height of the seat surface, it should also be noted that a good chair must have a seat with a width that is exactly the same, and the seat surface is too narrow, which may cause the user to feel uncomfortable because of the body. Both sides of the muscles will be squeezed; if the seat is too wide, the user's double buttocks will certainly open outwards, so that the user's latissimus dorsi and shoulder deltoid muscle and other tendon tissue will be pulled, If you sit long, you will feel tired.

Healthy seat standard 5 backrest tilted 110 degrees

The inclination of the backrest is also learned. In general, the backrest tilt angle is gradually increased backwards, and the support point of the human body also gradually shifts upwards. In general, the angle between the back of the seat and the thigh is about 100 to 110 degrees, and the posture in which the trunk is too upright tends to stress the spine.
