Very comfortable
I used it for my travel to India approx 22 hrs on the flight . there  are was no swelling in my feet . I was so comfortable using it and I think it also helped me with my acid reflux . The best thing ever . I showed it to my brother in India and he ordered 2 of them. My journey was very comfortable unlike my passenger sitting next to me who was struggling to put her feet up somehow and her feet got swollen too
