In addition to choosing suitable sofas, mattresses, and other everyday furniture, our daily work cannot completely sever the relationship with the chair. How to adjust the sitting posture and choose a chair that is fit for health is particularly important. What should be more comfortable with the chairs below ? What are the conditions for a comfortable chair ?
The comfort of the seat is related to the scale of the human body. There are differences between the crowd and the crowd. Generally speaking, northerners are tall, southerners are slightly dwarf, and North America and Europe are the same; men and women are different, and individuals and individuals are also different. So, Shu is uncomfortable, try it out before knowing, mainly to look at the following points:
Health chair standard
Seat height no lower than 39cm
The height of the seat should be equal to the length of the lower leg. After sitting down, the calf will naturally hang down and the soles of the foot will fall. Too high, calf hanging, too much pressure on the lower thigh for too long; the seat is too low, the thigh is not placed on the seat, the weight of the body is concentrated on the buttocks, and it will be uncomfortable for a long time.
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.
To sit in a chair, the depth of the seat should be equal to the length of the thigh. After sitting down, the knee bends to the side of the chair, the seat surface is too deep, and the back is not covered; the seat is too shallow and the thigh is not adequately supported. Uncomfortable.
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.
In a good chair, the width of the seat surface must be exactly the same, and the seat surface is too narrow, which can cause discomfort to the user because the muscles on both sides of the body are squeezed; if the seat surface is too wide, use The hips of the other person will certainly open outwards, so that the tendon tissue of the user's latissimus dorsi and shoulder deltoid muscles will be pulled, and if they sit for a long time, the user will feel tired.
Backrest tilts 110 degrees
The backrest of a good chair is also very elegant. In general, a backrest is not a necessary part of a chair. If a user has a large range of activities and wishes to be able to flexibly turn and pick up items, a chair without a backrest can be selected.
The backrest is best able to support all or part of the waist, back and neck. The longer you sit, the better your support. Dining chairs can be ignored because they are used only for meals, and office chairs are better for them. The size of imported furniture is often more suitable for people in the country of production.
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 chair is too soft and hurt
Ouyifeng furniture also feels the importance of the chair's hardness and hardness. Knowledge of human anatomy and physiology tells us that when sitting, people's lumbar load is larger than that of standing. The position of the spine and pelvis should be vertical, and its vertical fixed position should be from the spine. The muscles on both sides are maintained. 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, he should try to move the buttocks when he sits down, so that the back is close to the backrest of the chair instead of Floating, but also can consider adding a cushion to his waist as a support.
