A bed structure includes a frame, a deck framework moveably connected to the frame, a panel moveably connected to the deck framework, and a motion converter. The motion converter translates the panel relative to the deck framework in response to either or both of a) relative translation between the deck framework and the frame, and b) relative rotation of the deck framework and the frame. In one detailed embodiment the motion converter includes a rack secured to the frame, a primary gear meshing with the rack, a panel drive sprocket rotatably mounted on the deck framework coaxially with the primary gear, an idler sprocket rotatably mounted on the deck framework remote from the panel drive sprocket, a slider connected to the panel, and a chain engaged with the panel drive sprocket and the idler and connected to the slider.
