The bed device has load measurement means for generating a load signal; first computation means for computing a center-of-gravity variation or load variation on the basis of the load signal; first determination means for determining whether the computation result for the center-of-gravity variation or load variation is equal to or greater than a first threshold value; totaling means for totaling the number of times that the computation result is determined to be equal to or greater than the first threshold value; second computation means for multiplying the totaling results by coefficients for each time period and adding the results; and second determination means for determining a waking or sleeping state or determining a body movement or rest state of a user on the basis of whether a computation result of the second computation means is equal to or greater than a second threshold value. Movement of a user can thereby be monitored by using load information of a bed unit, and the waking state or body movement state of the bed user can be detected with high precision. |
