So far OK, has some issues
The pillow perform well in absorbing road shock - this was good. The size and dimensions are difficult to manage in the car seat as it overlaps. Getting out of the car is difficult due to the seat wanting to slide out. Of concern is the coefficient of restitution of the material. After a long trip the seat is still compressed and is not restoring back to the original height. The  purple advertisements on Google are Goofy and  a turn off for mature adults. If you can deal with the above go for it, overall it helped.<br /><br />P.S. my weight is 170 lb of compression force
