An air-operated device for better sleep includes a pad whose inside has an interlayer composed of two sheets stacked together. The top surface of the pad has an accommodating cavity in communications with the interlayer. The pad has an air vent. Two airbags are disposed adjacently in the accommodating cavity. The airbags are in touch with the interlayer by the adjacent side. The airbags are connected to the air vent of the pad via an air-transporting pipe, respectively. An action pad is disposed correspondingly in the accommodating cavity and depresses the two airbags. A controller is connected to the air vent of the pad to inflate and deflate the airbags. When the airbags are inflated, the action pad is pushed by the air bags to sway upward.
