I drive an hour and a half to work each morning and talk about a sore butt. I needed to find a car seat that would relieve the pressure points of a regular car seat and cushion my ride, well this cushion worked. It's a wedge shaped cushion that is thick in the back and narrows toward the front where I don't need as much support under my legs. It's soft comfortable memory foam support is exactly what I needed and a good fair price. It's got like a non-slip coating so I'm not slipping around on the seat. I like it and would recommend to anyone looking for memory foam comfort.
