On my numerous flights to see my grandchildren in Orlando (5 hours), my back absolutely ached! I was beginning to think I would have to take a flight with 2-3 stops so I could rest my back. My friends and I planned a trip to Hawaii–nonstop! I began looking into some kind of back support–I am 5′ so plane seats just do not "fit" a person of my stature! I sent for your cushions and received them just in time for Hawaii them.I could only fit the "seat" cushion in my carry on( I always over pack) Your cushion is absolutely amazing–no stiffness,no aches nor pain! Thank you so much for designing this product! Now I am confident that I’ll be comfortable traveling to visit my grandchildren no matter how long the flight!! ..More
