Works anatomically! Light to carry!
Unlike a horse-shoe pillow (including those that inflate) -- Trtl supports head erect or slightly to the side, keeping the chin from bouncing off the chest. Econo seats do not recline enough to use the airline's own pillow, much less one is like a donut. This is the second one of these I bought because my husband claimed the first one!
