Abstract

A foldable bed includes a base, a first frame and a second frame. The first frame is provided with two chest and abdomen support rods. The first frame is connected with two retractable bars which are connected with a head support. The second frame is provided with a plurality of support bars. Thus, when the user is disposed at a prone positioning state, the two chest and abdomen support rods are adjusted to fit the user's body, such that the user's chest and abdomen are exposed and will not be compressed, while the head support is adjusted to fit the user's face, such that the user's eyes, nose, mouth and ears are exposed and will not be compressed, to prevent the user's respiratory tract from being clogged.
