I have acid reflux and sometimes use a wedge pillow. Somehow I got to thinking it might be useful to use one of these on an airplane to simulate seat recline. Most of these are about 32-inches wide, so I would need to cut one in half.

A couple of notes. First, I'm 5-10 and find that most planes have super-plentiful legroom. So shifting my butt forward a few inches isn't likely to cause any legroom problems. Second, I find the way that the airline seats actually lean forward to be really uncomfortable and to make it hard to breathe (I don't have severe asthma attacks, but do have constant minor problems breathing). As a practical matter, airline seats no longer recline at all.

So anyway, I started shopping Amazon for a 7-inch-rise wedge pillow that I could cut in half so that it would be 16-inches wide when I stumbled upon something called a "dual-position wedge." This is listed at 19 inches wide, although customers say it is 18 or 18.5. So I will still need to trip the edges with a razor blade to fit a 17-inch-wide airplane seat. It has a 12-inch rise, which I think may be too much and may require more razor blade surgery. But with all that said, it looks like it might make it possible to lean back and stretch out on transatlantic or other very long flights.

Does anyone have any experience using anything like this? Does it count as my one personal item? What if I have a medical note. I've ordered one of these and am going to try it in a couple of chairs at home to see how it works. If it doesn't, I'll probably send it back.
