Multifunctional split mother-and-son bed

The utility model relates to a multifunctional split type major-and-sub bed which is formed by the combination of a major bed and a sub bed, wherein the sub bed can freely enter and go out from the major bed through a guide sliding bar on the lower part of the major bed, and a hook is arranged on the guide sliding bar and enables the major bed and the sub bed to be engaged or disengaged with each other; when needed, the sub bed can be pulled out to be fixed to any position selected; when not used, the sub bed is pushed to a position under the major bed; thus, a crowded phenomenon during sleeping is overcome and the original shapely configuration of a room is not affected. One end of the major bed body is connected with a square tube horse, and the other end is arranged on a bed foot cabinet. Two moveable backrests on which two moveable arm rests are installed on the square tube horse, and thus, the utility model can be used as a reclining chair; as short guard bars and a rubber band mesh enclosure are installed on both sides of the sub bed, children can be prevented from falling down or kicking off quilts. The utility model is convenient to fabricate, and can be of a woody or a steel-wood structure.
