PASSENGER SEAT ARMREST WITH A MULTI-ZONE TOP SURFACE

An armrest for a passenger seat has a forward end, an aft end opposite from the forward end, and a top surface extending from the forward end to the aft end. The top surface includes a first zone and a second zone, and a curvature of the first zone of the top surface is different from a curvature of the second zone of the top surface. In some examples, at least one of the first zone or the second zone has a concave curvature.
