The depth of the seat is between 48 and 55 cm, and when the back is pressed against the back of the sofa as far as possible, the knee should still be outside the table. From the ground, the height of the sofa bed backrest should be between 68-72 cm, within this range, comfort is the strongest. In addition, the tilt of the backrest is best between 100-108 degrees, and the height of the handrail is 62-65 cm.
