A user cannot make contact with the seam line during sleep, which allows the user to sleep better and more comfortable and is more suitable for the demands of people.

The top layer and the bottom layer are joined at the sides of the novel cake-type air bed.

Alternatively, the top layer extends from the top surface of the novel cake-type air bed to the sides and the bottom surface, and is welded or bonded with the bottom layer at the bottom surface of the novel cake-type air bed.

Alternatively, the top layer and the bottom layer are integrally formed to form the cavity of the air bed.

Further, as another embodiment, a surrounding band is also included. The surrounding band is provided on the sides of the novel cake-type air bed and between the top layer and the bottom layer.
