How big is the sofa bed size?

1. General size standards
From the current point of view, there is no uniform standard for sofa beds. Because each person's needs, room area and layout are different, the required size is also different. In fact, the size of the sofa bed is similar to that of the sofa, but slightly larger, but the sofa bed can be ergonomically referenced, so that users can feel very comfortable whether they are lying or sitting. For this reason, when buying or customizing a sofa bed, you can roughly measure the size.

2. Seat height
Under normal circumstances, the height of the sofa bed is similar to the height of the calf of the human body, roughly in the range of 35 to 42 cm. Too high or too low is not conducive to the relaxation of human muscles, because sitting for a long time will make people feel back pain. The experience effect is poor, and it will also harm human health. Therefore, the design of the height of the sofa bed only needs to be consistent with the height of the human calf.

3. The inclination of the backrest
As we all know, when the human body sits on the sofa, it usually backs against the sofa, and the inclination of the backrest is controlled at about 100 to 108°, and the height of the armrest is about 62 to 65 cm. This is the best comfortable state. Of course, when buying or customizing the sofa bed, you should experience the comfort level yourself. After all, everyone feels different.
