Abstract: An improved structure of a ventilated mattress with cooling and warming effect is disclosed. The structure comprises a mattress body, a warming/cooling air-delivery controlling box, and a connecting tube. The control box produces warming/cooling air to the mattress body via the connecting tube and the warming/cooling air is released via a plurality of ventilation buttons mounted at the surface of the mattress body. Thereby, the mattress provides the user with a warming/cooling effect.
