A base seat for a bed, chair or sofa includes a fixation base, first and second rocking mounts, four arms pivotally connected between the fixation base and the first rocking mount such that a distance between top ends of each paired arms is smaller than a distance between bottom ends of the paired arms, and another four arms pivotally connected between the first and second rocking mounts such that a distance between top ends of each paired arms is smaller than a distance between bottom ends of the paired arms. First and second drive devices respectively drive the first and second rocking mounts to swing leftward and rightward relative to the fixation base and forward and backward relative to the first rocking mount along first and second arc paths with variable inclined angles, such that the base seat has a multidirectional swinging function with desired inclined angles during swinging.
