Didn't work
I bought this because I have arthritis in my hips and wanted it to get in and out of my SUV. This one in particular did not significantly increase the height of the seat and that was a large part of my decision. It arrived and seemed to be of good construction and what i expected. So, I put it on my seat and got in the car. I tried to swivel and it just didn't work at all. I expect it would be fine on a hard chair surface, but, on a car seat it doesn't perform as advertised. A disappointment to be sure.
