Whether the seat is comfortable is related to the scale of the body. The crowd is different from the crowd, the northerners are tall, the southerners are slightly short, and North America and Europe are different, and there are differences between men and women and individuals and individuals. So, comfortable, try to know, mainly look at the following points:

1. Seat height: should be equal to the length of the calf, sit down after the calf natural droop, the soles of the feet just landed. Too high, leg hanging, under the thigh oppressed too much too long too bad, the seat is too low, thighs can not be placed on the seat surface, the body weight to the hip pressure, a long time will not be comfortable.

2. Seat depth: Sitting on the main chair, the seat should be equal to the length of the thigh, sit down after the knee to the corner of the chair, the seat is too deep, the waist is not landing, the seat is too shallow, the thigh is not enough support, are uncomfortable.

3. Chair and chair back material: both should be "glove" type-the bracket should be strong enough, but the surface has a certain thickness of the elastic layer. The outermost contact with the human body materials should be breathable, wear-resistant, dirty, and not easy with the human body or clothing to produce static electricity.

4. Chair back: It is best to the waist, back and neck to play all or part of the supporting role. The longer the chair sits, the better it will be. The dining chair is used only when dining, can ignore the neck, but the office chair is best to be able to take care of. The size of imported furniture is often more suitable for the people in the country of production.

5. Armrest: It is best to use adjustable height.
