A cover for an aircraft passenger using a bed surface of an aircraft passenger seat, the cover comprising:

• an upper layer comprising an inflatable bladder, wherein the inflatable bladder is configured to extend across at least 50% of the width of a knee region of the bed surface;
• a lower layer connected to the upper layer along one side, and the upper layer is connected to, or connectable to via a closure, the lower layer along an opposite side, the lower layer spreading across the top of the bed surface;
• a space between the upper layer and the lower layer configured to receive a passenger;
• an attachment mechanism for attaching the lower layer to the bed surface;
• and
• a trigger mechanism for triggering inflation of the inflatable bladder,
• wherein the cover is arranged to cover a passenger in close proximity to the passenger when lying on the bed surface, and
• wherein when the inflatable bladder is inflated, the cover is configured to provide pinning down of the passenger such that sliding of the passenger along the bed surface in a forward, a backward and sideways directions is restricted.
