I bought this inflatable portable (luxury ?) travel cushion to try and give relief to a 12 hour flight from Amsterdam to Kuala Lumpur. IT WORKED!!! Great buy, my wife who followed on did not use it on the outward journey but certainly did on the return and was amazed at the relief enabling sleep to occur. Suggest only half inflation but that,s my choice to get maximum comfort. Well worth the money and the looks from my fellow passengers who asked where to get them from showed their discomfort at my comfort. Will get more to give away to associates who travel on business to Malaysia and the Far East. They should sell these at airports.
