A siderail assembly for a patient-support apparatus including a frame and defining a head end, a foot end longitudinally spaced-apart therefrom, and two laterally spaced-apart sides, comprises a siderail body and a movement assembly. The movement assembly is coupled to the siderail body and is configured to be coupled with the frame of the patient-support apparatus. The movement assembly is configured so that the siderail body moves relative to the frame about a generally laterally-extending axis between a lowered position, a first raised position, and a second raised position laterally spaced apart from the first raised position.
