Review on Yupbizauto Breathable Comfortable Ergonomic Support Interior Accessories by David Bartan

Pillow surprisingly well designed for the price. I needed this to relieve my hip while driving and this pillow helps me with that. Keep in mind that the foam isn't the hardest; Although the basic measurements given are accurate, the pillow will compress at least 1 inch when you sit on it. I was fine with this because I'm 6'1" and ride in a car, but if you really need to get up 3 inches you might need a firmer foam. The pillow also holds up as promised. While tucking the rear valve under the seat back. My car has cloth seats and they may behave differently if you have leather or vinyl. Note that the rear flap will only work on a seat or chair with a narrow gap between the seat back and the bottom. I found it was a bit tight for me and I don't have a very wide butt. I have about half an inch of slack on each side, and sometimes it can be difficult to stay centered without slipping off one side. If they added two inches it would be perfect. If you are a taller person, you may need a wider pillow.
