Review on ✈️ TravelMate Large Medium-Firm Wellness Seat Cushion - Optimal Comfort for Traveling - 17 x 13 x 3 inches by Heather Wilson

I didn't get this because I needed to sit higher, it was because the seats in our small car have too much of a height difference between the front and back of the seat, so it irritates the hollows of my knees and my legs start to get too tingle. I needed something to lift me up to take that pressure off. This seat cushion is wide as other reviews have said, so consider the dimensions before purchasing. It's also VERY firm, so I'm actually sitting a few inches taller. (and staying there - it doesn't seem to break down in a 6 hour drive I drove all the way). If you're looking for a soft, comfortable seat, this isn't it. The cover is removable, so I'll definitely take it off regularly to wash it (by hand I'm sure). Safe purchase!
