Whether the        horn chair is comfortable is related to the size of the human body.There are differences between the crowd and the crowd. On the whole, people in the North are tall, people in the South are slightly smaller, and so are people in North America and Europe. There are differences between men and women, and there are also differences between individuals and individuals.So comfortable and uncomfortable, try to know, mainly look at the following points:
1. Seat height: It should be equal to the length of the calf. The calf will naturally sag after sitting down, and the foot will land on the ground.Too high, the calf is suspended, and the pressure under the thigh is too much and too long; the seat surface is too low, the thigh cannot be placed on the seat surface, and the weight of the human body is concentrated to the hip, and it will be uncomfortable for a long time.
2. Seat depth: The seat position of the horn chair should be equal to the length of the thigh. The bend of the back knee joint is right at the edge of the chair. The seat surface is too deep, and the waist and back are not landed; the seat surface is too shallow, and the thigh is not supported accordingly, so it will be uncomfortable.
3. Material of the chair top and back: Both should be of the "outer soft and inner rigid" type - the bracket should be strong, but the surface has an elastic layer of corresponding thickness.
4. Chair back: It can play a partial supporting role on the waist, back and neck.The longer you sit in the chair, the better the support.
       5. Handrail: Select one that can adjust the position.
