摘要：
The present invention provides a bottom structure for a bed having a bottom lifting mechanism, comprising plural parallel bottom strips; each of the bottom strips being sequentially connected to allow bottom bending; and each of the bottom strips, having a tenon formed in the longitudinal axial direction of the bed on one of the faces to be face-to-face with the adjacent bottom strip, and having a mortise formed in the opposite face, so as to be loosely engaged with the tenon of the adjacent bottom strip.
