The width of the rotating plate 3 after rotation is smaller than the length of the installation space 2, so that a passage for convenient entry and exit is formed between the two ends of the rotating plate 3 and the two ends of the installation space 2.

[0024] When used as a bed, the rotating plate 3 rotates under the drive of the rotating mechanism so that the length of the rotating plate 3 is parallel to the length of the installation space 2, and then descends under the drive of the lifting mechanism to embed the rotating plate 3 into the installation space 2, and the upper end of the rotating plate 3 is flush with the upper end of the main body 1, thereby filling and leveling the upper end of the main body 1 to form a complete rectangular surface, and you can fall asleep after putting the mattress on it.
