Shape/thickness is useless for most seats.
The softness is good but the size/shape doesn't fit anything. It is too small and square for my car seat, too big and overlapping for my office chair, it is super thick and raises the level of the seat so much that driving or desk sitting is out of whack. Plus it has a tag on the side with a sharp edge that digs into my legs. I'm going to try it on a few more seats I use regularly but I wish they would make a shape more designed for a car since that is really what I bought it for.
