Great cushion for all methods of travel after trying so many others.
I deal with a piriformis problem that was caused by several car accidents.  I also travel a lot, some times for extended periods in other countries where it can be difficult to find a good office chair and I sit all day.  This cushion has been a game changer for me. I utilized it on 2 plane flights from OR to LA and on to Costa Rica and the amount of pain was lessened.  I'm now using it on a hard kitchen table chair and I'm able to sit all day without issue.  I'm about 215 lbs and the cushion maintains it's shape well and provides a nice cushion.  This particular model is big, but I'm glad I went with the large one as it has been a good platform for several methods of travel.
