Great as a Lumber support not a wonderful travel pillow
There is a strap that can be used to hold this in place as a lumber support on a chair or seat in a car.  It works well but could be better with an additional support stram going u as well as this horizontal strap. Inserting the support into the case is difficult and takes some time, but can be done.  I am using the smaller side of the cushion as my support side - there are no directions or suggestions.
