This inflatable footrest was easy to use, compact to carry and helped me get 7 hours of sleep on a 12+ hour flight. I was seated in a bulkhead area, but I think it would work in most economy seats, although you would probably have an issue if you had a lot of luggage in your under-seat area. It especially helped my traveling partner who had recently had a hip replacement. Elevating legs may help avoid deep vein thrombosis so that’s another probable benefit.
