Yesterday I introduced to you all the height of the bed, and today I will introduce the height of the sofa. A reasonable furniture scale is crucial for people's lives. If not properly grasped, it can cause many inconveniences for users and even affect their health. The scale, shape, and layout of furniture design should conform to the physiological and psychological scales of the human body and the activity patterns of different parts of the human body, so as to achieve safety, practicality, convenience, comfort, and beauty.
For single-person sofas, the width before sitting should not be less than 48 centimeters. If smaller than this dimension, a person may be able to sit in勉强edly but still feel crowded. The depth of the seat should be within the range of 48-60 centimeters. If too deep, the lower leg cannot hang naturally, and the calf will be compressed; if too shallow, it will feel like one cannot sit stably. The height of the seat should be within the range of 36-42 centimeters. If too high, it feels like sitting on a chair and uncomfortable; if too low, it will be very difficult to sit down and stand up.
The seat height standard for double or triple sofas is the same as that for single-person sofas, while the seat width has corresponding changes. For triple sofas, the seat spacing for each person should ideally be 45-48 centimeters, and for double sofas, the seat spacing can be larger, generally 50 centimeters, depending on the user's body type. The armrests of the sofa are usually 56-60 centimeters high. If there are no armrests and corner tables are used instead, the height of the corner table should be 60 centimeters for convenient hand support or item retrieval.
