Very comfortable
I suffer from disc and spine pain in neck and driving/sitting long hours  this purple cushion has changed my life for the best. Love it  I  Originally bought the smaller version but that doesn't sit in the seat very well and I found myself sliding off of it or not being able to get comfortable That's why but the ultimate cushion its much bigger doesn't move around on the seat. Am always  comfortable now. I definitely want to recommend it to my friends.
