This invention is about a mattress equipped with vibration means. In order to generate fine vibration without noise, the mattress consisted of a cover and cushion part is characteristically installed with a multiple number of piezoelectric vibration elements vibrating by electricity at the prescribed positions on the aforementioned cushion part. Also, in order to enable operation without power connection from the outside, the mattress consisted of a cover and cushion part characteristically includes a multiple number of piezoelectric vibration elements vibrating by electricity; and piezoelectric generator elements installed at the prescribed positions of the aforementioned cushion part in multiple numbers and connected to the aforementioned piezoelectric vibration elements that generate electricity by weight of the user, therefore supplies the electricity to the aforementioned piezoelectric vibration elements.
