Size design basis

According to the human scale

Sofa size data is not set in stone; different styles of sofas have some differences in Size; ultimately, the furniture design should be based on human scale. Such as the human body’s standing position when the maximum range of activities of the reach, sitting position of the calf height and thigh length and upper body activities, sleeping position of the human body width, length and turnover range, etc., which are with the furniture size has a close relationship.

According to human engineering

The general sofa sitting surface is from the ground height of about 35-40 centimetres so that you can sit down. Sitting high should be equal to the height of the knee; the best thing is to be able to do all the way to sit on the sofa so the feet can still step on the floor. The Size of the sofa is still the most important according to ergonomics to determine, according to the human scale, China’s human body sitting thigh level length of the average: men 445mm, women 425mm, to ensure that the front edge of the sitting to leave the inside of the knee there is a certain distance of about 60mm, the sofa’s sitting depth dimensions of the sofa in the range of 380-420mm. The sitting width of the sofa is generally not less than 380mm; for the sofa with armrests, we should consider the human armrests, the inner width of the armrests as the sitting width of the Size, according to the human body’s average shoulder width plus an appropriate margin, generally not less than 460mm. Still, it should not be too broad and should be naturally dropping the arm of the shoulder width of the comfortable posture shall prevail. Sofa sitting surface tilt is generally 3-5 degrees, and the relative back of the chair is also tilted backward.

Sofa cushion size

1, The most comfortable sofa is the person in the seat. It can be a natural backrest, that is, the person’s back, head and shoulders are almost all contact with the back of the sofa; the more significant the contact area, the greater the sense of comfort of the body, and the more natural sitting posture, usually cushions and sofa backrest angle between the backrest and the sofa is not perpendicular to the 90 °, but in the 100 ° to 108 ° between.

Sofa bed size

Sofa beds are popular mainly because the city’s housing prices are too high, and many people working in big cities choose sofa beds for snail living. Therefore, sofa beds combine the use of both sofas and sleeper beds. Because the snail space is small, the size of the sofa bed is not much different from the couch, but it is smaller than the general bed.

The Size of a sofa bed should meet ergonomic principles.

Let a person either sit up or sleep down. It can be a very comfortable sofa bed or a good sofa bed; sofa bed size will be different according to the number of bits or other functions; the Size of the sofa bed will have some minor differences, but there are some ranges, such as

1. The height of the seat surface is between 35 and 42 centimetres, almost the height of the human calf. Too high or too low Size is not conducive to relaxing human muscles, and prolonged use will likely cause body aches and pains.

2, The depth of the seat between 48-55 centimetres is more appropriate; that is to say, when the back is as much as possible against the back of the sofa, the person’s knees should still be outside the seat surface. Calculated from the ground, the height of the backrest of the sofa bed should be maintained between 68-72 centimetres; within this range, the human body’s comfort is the strongest.
