The invention relates to the field of furniture and particularly discloses an automatic accompanying 
bed. The automatic accompanying 
bed comprises at least three bottom plates, wherein the adjacent bottom plates are hinged, a buffer layer is fixed to the top of each bottom plate, supporting legs are fixed to the bottom of the bottom plate at one side, and a supporting frame is hinged to the bottomof the bottom plate at the other side; a pull 
rope is fixed to the bottom plate where the supporting legs are fixed, and a stepping motor capable of rolling the pull 
rope is fixed to the supporting frame; a heating cavity is formed in each bottom plate, a plurality of hot air channels are formed in the top wall of each heating cavity, a 
piston is connected into each hot 
air channel in a verticalsliding mode, each 
piston is higher than the top of the corresponding bottom plate, a spring is fixed between each 
piston and the inner wall of the corresponding heating cavity, and each piston is provided with an exhaust channel which communicates with the corresponding heating cavity in the slide-down process; and each buffer layer is provided with a plurality of through holes, and each heatingcavity communicates with an air-in piece and a heating piece. According to the scheme, the accompanying 
bed can be unfolded slowly and automatically without being unfolded by manpower completely, andthe situation that a large sound is generated in the unfolding process is avoided.
