The backrest is arranged on one side of the bed body along the length direction of the bed body, and the armrest is arranged on the side of the bed body adjacent to the backrest. The number of the armrest is one, and the length of the armrest is less than half of the length of the bed body. The utility model only arranges the armrest on one side of the bed body, and the armrest serves as a place for the arm. At the same time, when a person lies on the sofa bed, the legs occupy the back half of the sofa bed. By arranging the armrest on half of the sofa bed, the armrest will not block the movement of the legs. Finally, the armrest is only arranged on one side, and the person can sit up or get out of bed from the other side, avoiding the problem of armrests on both sides causing the body movement to be blocked.

[0004] Although the above device can prevent the body movement from being blocked, there are still some problems when using the device:
