Does anyone have experience traveling on planes with a wedge/posture cushion (
this type of cushion)? If so, have they made a difference in terms of reducing fatigue or discomfort? Also, are they practical (e.g. carrying around, fitting in the seat, do they raise you too high in the seat, etc.) to use?
I've searched the forums but can't seem to find any threads on the use of wedge/posture cushions. I understand it's no doubt a personal preference thing, but any information or tips would be greatly appreciated.
Thank you very much for any help.
