Abstract
The present invention provides a bottom structure for a bed having a lifting mechanism and plural parallel bottom strips connected sequentially by elastic strips, thus allowing the bottom to be bent. The elastic strips are curved in areas not in contact with the bottom strips so that the bottom structure can be adjusted in length.
