A patient care bed includes a frame, a side rail, and a side rail mounting assembly. The side rail mounting assembly includes a rail-receiving member defining a passageway configured to releasably receive the side rail and a support rod fixedly engaged to and extending from the rail-receiving member. The support rod is slidable relative to the frame between a storage position, wherein the rail-receiving member is disposed within the frame, and a use position, wherein the rail-receiving member is disposed outside the frame. The support rod is rotatable relative to the frame between a storage orientation, wherein the rail-receiving member is horizontal, and a use orientation, wherein the rail-receiving member is vertical. The side rail mounting assembly is transitionable between a storage condition, corresponding to the storage position and orientation of the support rod, and a use condition, corresponding to the use position and orientation of the support rod.
